Subject: [PATCH 0001/1480] driver core: allow kobj_to_dev() to take a const
 pointer

If a const * to a kobject is passed to kobj_to_dev(), we want to return
back a const * to a device as the driver core shouldn't be modifying a
constant structure.  But when dealing with container_of() the pointer
const attribute is cast away, so we need to manually handle this by
determining the type of the pointer passed in to know the type of the
pointer to pass out.

Luckily _Generic can do this type of magic, and as the kernel now
supports C11 it is availble to us to handle this type of build-time type
detection.

Subject: [PATCH 0002/1480] USB: allow some usb functions to take a const
 pointer.

The functions to_usb_interface(), to_usb_device, and
interface_to_usbdev() sometimes would like to take a const * and return
a const * back.  As we are doing pointer math, a call to container_of()
loses the const-ness of a pointer, so use a _Generic() macro to pick the
proper inline function to call instead.

With the changes to the driver core to make more pointers const, the USB

callback so that the driver core's constant pointer will also be
properly propagated.

Subject: [PATCH 0004/1480] kernfs: dont take i_lock on inode attr read

The kernfs write lock is held when the kernfs node inode attributes
are updated. Therefore, when either kernfs_iop_getattr() or
kernfs_iop_permission() are called the kernfs node inode attributes
won't change.

Consequently concurrent kernfs_refresh_inode() calls always copy the
same values from the kernfs node.

So there's no need to take the inode i_lock to get consistent values
for generic_fillattr() and generic_permission(), the kernfs read lock
is sufficient.

Subject: [PATCH 0005/1480] kernfs: dont take i_lock on revalidate

In kernfs_dop_revalidate() when the passed in dentry is negative the
dentry directory is checked to see if it has changed and if so the
negative dentry is discarded so it can refreshed. During this check
the dentry inode i_lock is taken to mitigate against a possible
concurrent rename.

But if it's racing with a rename, becuase the dentry is negative, it
can't be the source it must be the target and it must be going to do
a d_move() otherwise the rename will return an error.

In this case the parent dentry of the target will not change, it will
be the same over the d_move(), only the source dentry parent may change
so the inode i_lock isn't needed.

Remove the bLedLinkBlinkInProgress component from struct led_priv. Its
only use is to block requests for "link blinking" when this blinking
pattern is already active.

The "link blinking" pattern is a continuous blinking pattern (as opposed
to other patterns where we blink N times), it's no problem to restart this
pattern when it's already running.

bFwCtrlLPS is just once initialized and never changed. The evaluation will
always have the same result. Remove resulting dead code.

Subject: [PATCH 0019/1480] staging: r8188eu: merge odm_types.h into other
 headers

The macros SET_TX_DESC_ANTSEL_{A,B,C}_88E are used in odm_RTL8188E.c.
Move them from odm_types.h to odm_RTL8188E.h.

ODM_CE is used in places where also ODM_ITRF_USB is used in the code.
Move the ODM_CE define to the header that defines ODM_ITRF_USB. While
at it remove an extra space between '#' and 'define ODM_ITRF_USB'.

The haeder odm_types.h is now empty and we can remove it.

Define a struct ieee80211_mgmt for the message that we process in
OnDeAuth. Use this struct to read the bssid.

This patch removes one GetAddr3Ptr call, getting us a tiny step closer to
removing GetAddr3Ptr.

 assignment

bBusyTraffic is set only if we're not in WIFI_AP_STATE, i.e. in the else
branch. If we were not in WIFI_AP_STATE, we'd go into the if branch and
return _SUCCESS before making it to the bBusyTraffic assignment.

Move the assignment into the else branch to make this clearer.

Subject: [PATCH 0042/1480] staging: r8188eu: exit for deauth from unknown
 station

If we receive a deauth message from an unknown station, we can drop this
message and exit immediately. Reorder the code to make this clearer, don't
wrap everything in an if statement.

Subject: [PATCH 0050/1480] staging: r8188eu: fix led register settings

Using an InterTech DMG-02 dongle, the led remains on when the system goes
into standby mode. After wakeup, it's no longer possible to control the
led.

It turned out that the register settings to enable or disable the led were
not correct. They worked for some dongles like the Edimax V2 but not for
others like the InterTech DMG-02.

This patch fixes the register settings. Bit 3 in the led_cfg2 register
controls the led status, bit 5 must always be set to be able to control
the led, bit 6 has no influence on the led. Setting the mac_pinmux_cfg
register is not necessary.

These settings were tested with Edimax V2 and InterTech DMG-02.

Subject: [PATCH 0056/1480] staging: r8188eu: don't include rtw_led.h from
 rtw_cmd.h

The rtw_cmd.h does not need any definitions from the led layer, there's
no reason to include rtw_led.h.

When I tried to remove this component

struct led_priv {
   struct adapter *padapter;
   ...

I saw compiler errors because of this chain of include files:
drv_types.h -> rtw_cmd.h -> rtw_led.h

rtw_led.h uses struct adapter before it sees the definiton near the end
of drv_types.h. (It seems that a simple struct adapter * prevents this
problem.)

The best option for fixing this issue is to not include rtw_led.h in
rtw_cmd.h.

The only struct led_priv that's used in the r8188eu driver in embedded in
the driver's global struct adapter. We can use container_of to access the
"outer" structure, there's no need to store a pointer to it.

Subject: [PATCH 0058/1480] staging: r8188eu: set two more state variables

Set two more state variables in the blink worker when scan blinking and
tx/rx blinking are finished.

bLedBlinkInProgress is true during tx/rx blinking, bLedScanBlinkInProgress
is true during scan blinking. If we doing neither of the two, we may
safely set both variables to false.

This change makes the scan and tx/rx cases almost identical, we are now
ready to summarize the two cases.

Subject: [PATCH 0061/1480] staging: octeon: remove redundant variable
 total_freed

The variable total_freed is accumulating skb_to_free however it is not
being used after this. The use of total_freed is redundant and hence
the variable can be removed.

Subject: [PATCH 0076/1480] staging: r8188eu: Associate pointer symbol with
 parameter name

The pointer symbol '*' should be associated with the function parameter
name and not its type. This improves code readability and adheres to the
coding-style guidelines. Address following checkpatch reported error:
	ERROR: "foo *   bar" should be "foo *bar"

While in there, update parameter name at one place to match other function
declarations.

Simple variants of macros PlatformEFIOWrite and PlatformEFIORead are
defined but never used. As they do not appear to be designed for anything
significant, we can remove them to avoid unexpected usage.

Subject: [PATCH 0091/1480] usb: gadget: uvc: default the ctrl request
 interface offsets

For the userspace it is needed to distinguish between requests for the
control or streaming interface. The userspace would have to parse the
configfs to know which interface index it has to compare the ctrl
requests against. Since the interface numbers are not fixed, e.g. for
composite gadgets, the interface offset depends on the setup.

The kernel has this information when handing over the ctrl request to
the userspace. This patch removes the offset from the interface numbers
and expose the default interface defines in the uapi g_uvc.h.

- *
- * - See musb_{host,gadget}.c for more info
- *
- * - Correct RX DMA generally forces the engine into irq-per-packet mode,
- *   which can easily saturate the CPU under non-mass-storage loads.
- *
- * NOTES 24-aug-2006 (2.6.18-rc4):
- *
- * - peripheral RXDMA wedged in a test with packets of length 512/512/1.
- *   evidently after the 1 byte packet was received and acked, the queue
- *   of BDs got garbaged so it wouldn't empty the fifo.  (rxcsr 0x2003,
- *   and RX DMA0: 4 left, 80000000 8feff880, 8feff860 8feff860; 8f321401
- *   004001ff 00000001 .. 8feff860)  Host was just getting NAKed on tx
- *   of its next (512 byte) packet.  IRQ issues?
- *
- * REVISIT:  the "transfer DMA" glue between CPPI and USB fifos will
- * evidently also directly update the RX and TX CSRs ... so audit all
- * host and peripheral side DMA code to avoid CSR access after DMA has
- * been started.

- * ========

- * (except how it handles the exactly-N-packets case).  Building a
- * txdma queue with multiple requests (urb or usb_request) looks
- * like it would work ... but fault handling would need much testing.
- *
- * The main issue with TX mode RNDIS relates to transfer lengths that
- * are an exact multiple of the packet length.  It appears that there's
- * a hiccup in that case (maybe the DMA completes before the ZLP gets
- * written?) boiling down to not being able to rely on CPPI writing any
- * terminating zero length packet before the next transfer is written.
- * So that's punted to PIO; better yet, gadget drivers can avoid it.
- *
- * Plus, there's allegedly an undocumented constraint that rndis transfer
- * length be a multiple of 64 bytes ... but the chip doesn't act that
- * way, and we really don't _want_ that behavior anyway.
- *
- * On TX, "transparent" mode works ... although experiments have shown
- * problems trying to use the SOP/EOP bits in different USB packets.
- *
- * REVISIT try to handle terminating zero length packets using CPPI
- * instead of doing it by PIO after an IRQ.  (Meanwhile, make Ethernet
- * links avoid that issue by forcing them to avoid zlps.)

- * CPPI RX Woes:
- * =============
- * Consider a 1KB bulk RX buffer in two scenarios:  (a) it's fed two 300 byte
- * packets back-to-back, and (b) it's fed two 512 byte packets back-to-back.
- * (Full speed transfers have similar scenarios.)
- *
- * The correct behavior for Linux is that (a) fills the buffer with 300 bytes,
- * and the next packet goes into a buffer that's queued later; while (b) fills
- * the buffer with 1024 bytes.  How to do that with CPPI?
- *
- * - RX queues in "rndis" mode -- one single BD -- handle (a) correctly, but
- *   (b) loses **BADLY** because nothing (!) happens when that second packet
- *   fills the buffer, much less when a third one arrives.  (Which makes this
- *   not a "true" RNDIS mode.  In the RNDIS protocol short-packet termination
- *   is optional, and it's fine if peripherals -- not hosts! -- pad messages
- *   out to end-of-buffer.  Standard PCI host controller DMA descriptors
- *   implement that mode by default ... which is no accident.)
- *
- * - RX queues in "transparent" mode -- two BDs with 512 bytes each -- have
- *   converse problems:  (b) is handled right, but (a) loses badly.  CPPI RX
- *   ignores SOP/EOP markings and processes both of those BDs; so both packets
- *   are loaded into the buffer (with a 212 byte gap between them), and the next
- *   buffer queued will NOT get its 300 bytes of data. (It seems like SOP/EOP
- *   are intended as outputs for RX queues, not inputs...)
- *
- * - A variant of "transparent" mode -- one BD at a time -- is the only way to
- *   reliably make both cases work, with software handling both cases correctly
- *   and at the significant penalty of needing an IRQ per packet.  (The lack of
- *   I/O overlap can be slightly ameliorated by enabling double buffering.)
- *
- * So how to get rid of IRQ-per-packet?  The transparent multi-BD case could
- * be used in special cases like mass storage, which sets URB_SHORT_NOT_OK
- * (or maybe its peripheral side counterpart) to flag (a) scenarios as errors
- * with guaranteed driver level fault recovery and scrubbing out what's left
- * of that garbaged datastream.
- *
- * But there seems to be no way to identify the cases where CPPI RNDIS mode
- * is appropriate -- which do NOT include RNDIS host drivers, but do include
- * the CDC Ethernet driver! -- and the documentation is incomplete/wrong.
- * So we can't _ever_ use RX RNDIS mode ... except by using a heuristic
- * that applies best on the peripheral side (and which could fail rudely).
- *
- * Leaving only "transparent" mode; we avoid multi-bd modes in almost all
- * cases other than mass storage class.  Otherwise we're correct but slow,
- * since CPPI penalizes our need for a "true RNDIS" default mode.
- */
-
-
-/* Heuristic, intended to kick in for ethernet/rndis peripheral ONLY
- *
- * IFF
- *  (a)	peripheral mode ... since rndis peripherals could pad their
- *	writes to hosts, causing i/o failure; or we'd have to cope with
- *	a largely unknowable variety of host side protocol variants
- *  (b)	and short reads are NOT errors ... since full reads would
- *	cause those same i/o failures
- *  (c)	and read length is
- *	- less than 64KB (max per cppi descriptor)
- *	- not a multiple of 4096 (g_zero default, full reads typical)
- *	- N (>1) packets long, ditto (full reads not EXPECTED)
- * THEN
- *   try rx rndis mode
- *
- * Cost of heuristic failing:  RXDMA wedges at the end of transfers that
- * fill out the whole buffer.  Buggy host side usb network drivers could
- * trigger that, but "in the field" such bugs seem to be all but unknown.
- *
- * So this module parameter lets the heuristic be disabled.  When using
- * gadgetfs, the heuristic will probably need to be disabled.

Subject: [PATCH 0094/1480] usb: dwc2: platform: Improve error reporting for
 problems during .remove()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Returning an error value in a platform driver's remove callback results in
a generic error message being emitted by the driver core, but otherwise it
doesn't make a difference. The device goes away anyhow.

For each case where ret is non-zero the driver already emits an error
message, so suppress the generic error message by returning zero
unconditionally. (Side note: The return value handling was unreliable
anyhow as the value returned by dwc2_exit_hibernation() was overwritten
anyhow if hsotg->in_ppd was non-zero.)

Subject: [PATCH 0095/1480] device property: Allow const parameter to
 dev_fwnode()

It's not fully correct to take a const parameter pointer to a struct
and return a non-const pointer to a member of that struct.

Instead, introduce a const version of the dev_fwnode() API which takes
and returns const pointers and use it where it's applicable.

With this, convert dev_fwnode() to be a macro wrapper on top of const
and non-const APIs that chooses one based on the type.

phy-generic uses the existance of the property "vcc-supply" to see if a
regulator is optional or not. Use devm_regulator_get_optional() instead
which exists for this purpose. Using devm_regulator_get_optional()
avoids "supply vcc not found, using dummy regulator" messages.

Subject: [PATCH 0103/1480] usb: chipidea: core: handle usb role switch in a
 common way

Currently, ci_usb_role_switch_set() may be called before system resume
stage when suspended. Worse yet, ci_hdrc device may stay at RPM_ACTIVE
state which will cause pm_runtime_get_sync() fail to resume the device.
In this case, role-switch may unable to complete transition process due
to not exit from lpm state or due to lack some means after system resume.

Same as ci_cable_notifier(), usb_role_switch could handle its events based
on ci_hdrc_cable mechanism.

Subject: [PATCH 0105/1480] usb: chipidea: core: add controller resume support
 when controller is powered off

For some SoCs, the controler's power will be off during the system
suspend, and it needs some recovery operation to let the system back
to workable. We add this support in this patch.

As there maybe more APIs of usbmisc for suspend and resume, group
them into imx_usbmisc_suspend/resume. Besides, introduced .power_lost_check
API, so that proper resume operations can be performed in power lost case.

Subject: [PATCH 0117/1480] fpga: zynq: Switch to use dev_err_probe() helper

In the probe path, dev_err() can be replaced with dev_err_probe()
which will check if error code is -EPROBE_DEFER and prints the
error name. It also sets the defer probe reason which can be
checked later through debugfs. It's more simple in error path.

Subject: [PATCH 0118/1480] fpga: lattice-sysconfig-spi: add Lattice sysCONFIG
 FPGA manager

Add support to the FPGA manager for programming Lattice ECP5 FPGA over
slave SPI sysCONFIG interface.

sysCONFIG interface core functionality is separate from both ECP5 and
SPI specifics, so support for other FPGAs with different port types can
be added in the future.

It came in from a staging driver that has been long removed from the
tree, and there are no in-kernel users of the macro, and it's very
dubious if anyone should ever use this thing, so just remove it
entirely.

Subject: [PATCH 0121/1480] linux/container_of.h: Warn about loss of constness

container_of() casts the original type to another which leads to the loss
of the const qualifier if it is not specified in the caller-provided type.
This easily leads to container_of() returning a non-const pointer to a
const struct which the C compiler does not warn about.

Subject: [PATCH 0123/1480] kset: fix memory leak when kset_register() returns
 error

Inject fault while loading module, kset_register() may fail.
If it fails, the kset.kobj.name allocated by kobject_set_name()
which must be called before a call to kset_register() may be
leaked, since refcount of kobj was set in kset_init().

To mitigate this, we free the name in kset_register() when an
error is encountered, i.e. when kset_register() returns an error.

A kset may be embedded in a larger structure which may be dynamically
allocated in callers, it needs to be freed in ktype.release() or error
path in callers, in this case, we can not call kset_put() in kset_register(),
or it will cause double free, so just call kfree_const() to free the
name and set it to NULL to avoid accessing bad pointer in callers.

With this fix, the callers don't need care about freeing the name
and may call kset_put() if kset_register() fails.

Move some code around in rtw_mlme_ext.c to make it simpler.

mlme_sta_tbl is used only by mgt_dispatcher. Move the table inside the
function. Move mgt_dispatcher behind the handler functions. We can then
make the handler functions static.

Subject: [PATCH 0135/1480] staging: r8188eu: change mlme handlers to void

The mlme handlers that are called from mgt_dispatcher return an error
code. mgt_dispatcher doesn't check this error code, we can remove it and
change the handler functions to void.

For now, make only the minimum changes to the handlers for removing the
error codes. If handlers can be simplified, that'll be done it separate
patches.

Subject: [PATCH 0136/1480] staging: r8188eu: remove unnecessary label

Subject: [PATCH 0154/1480] perf tools riscv: Add support for get_cpuid_str
 function

The get_cpuid_str function returns the string that contains values of
MVENDORID, MARCHID and MIMPID in hex format separated by coma.

The values themselves are taken from first cpu entry in "/proc/cpuid"
that contains "mvendorid", "marchid" and "mimpid".

Subject: [PATCH 0155/1480] perf arch events: riscv sbi firmware std event
 files

Firmware events are defined by "RISC-V Supervisor Binary Interface
Specification", which means they should be always available as long as
firmware supports >= 0.3.0 SBI.

Expose them to arch std events, so they can be reused by particular PMU
bindings.

Subject: [PATCH 0157/1480] perf tools: Save evsel->pmu in parse_events()

Now evsel has a pmu pointer, let's save the info and use it like in
evsel__find_pmu().  The missing feature check needs to be changed as the
pmu pointer can be set from the beginning.

Subject: [PATCH 0159/1480] perf stat: Use evsel__is_hybrid() more

In the stat-display code, it needs to check if the current evsel is
hybrid but it uses perf_pmu__has_hybrid() which can return true for
non-hybrid event too.  I think it's better to use evsel__is_hybrid().

Also remove a NULL check for the 'config' parameter in the
hybrid_merge() since it's called after config->no_merge check.

Subject: [PATCH 0160/1480] perf stat: Add aggr id for global mode

To make the code simpler, I'd like to use the same aggregation code for
the global mode.  We can simply add an id function to return cpu 0 and
use print_aggr().

No functional change intended.

Subject: [PATCH 0162/1480] perf stat: Add 'needs_sort' argument to
 cpu_aggr_map__new()

In case of no aggregation, it needs to keep the original (cpu) ordering
in the aggr_map so that it can be in sync with the cpu map.  This will
make the code easier to handle AGGR_NONE similar to others.

Subject: [PATCH 0164/1480] perf stat: Allocate evsel->stats->aggr properly

The perf_stat_config.aggr_map should have a correct size of the
aggregation map.  Use it to allocate aggr_counts.

Also AGGR_NONE with per-core events can be tricky because it doesn't
aggreate basically but it needs to do so for per-core events only.
So only per-core evsels will have stats->aggr data.

Note that other caller of evlist__alloc_stat() might not have
stat_config or aggr_map.

Subject: [PATCH 0165/1480] perf stat: Aggregate events using
 evsel->stats->aggr

Add a logic to aggregate counter values to the new evsel->stats->aggr.
This is not used yet so shadow stats are not updated.  But later patch
will convert the existing code to use it.

With that, we don't need to handle AGGR_GLOBAL specially anymore.  It
can use the same logic with counts, prev_counts and aggr_counts.

Subject: [PATCH 0166/1480] perf stat: Factor out evsel__count_has_error()

It's possible to have 0 enabled/running time for some per-task or per-cgroup
events since it's not scheduled on any CPU.  Treating the whole event as
failed would not work in this case.  Thinking again, the code only existed
when any CPU-level aggregation is enabled (like per-socket, per-core, ...).

To make it clearer, factor out the condition check into the new
evsel__count_has_error() function and add some comments.

Subject: [PATCH 0168/1480] perf stat: Allocate aggr counts for recorded data

In the process_stat_config_event() it sets the aggr_mode that means the
earlier evlist__alloc_stats() cannot allocate the aggr counts due to the
missing aggr_mode.

Do it after setting the aggr_map using evlist__alloc_aggr_stats().

Subject: [PATCH 0171/1480] perf stat: Add perf_stat_merge_counters()

The perf_stat_merge_counters() is to aggregate the same events in different
PMUs like in case of uncore or hybrid.  The same logic is in the stat-display
routines but I think it should be handled when it processes the event counters.

As it works on the aggr_counters, it doesn't change the output yet.

Subject: [PATCH 0172/1480] perf stat: Add perf_stat_process_percore()

The perf_stat_process_percore() is to aggregate counts for an event per-core
even if the aggr_mode is AGGR_NONE.  This is enabled when user requested it
on the command line.

To handle that, it keeps the per-cpu counts at first.  And then it aggregates
the counts that have the same core id in the aggr->counts and updates the
values for each cpu back.

Later, per-core events will skip one of the CPUs unless percore-show-thread
option is given.  In that case, it can simply print all cpu stats with the
updated (per-core) values.

Subject: [PATCH 0173/1480] perf stat: Add perf_stat_process_shadow_stats()

This function updates the shadow stats using the aggregated counts
uniformly since it uses the aggr_counts for the every aggr mode.

It'd have duplicate shadow stats for each items for now since the
display routines will update them once again.  But that'd be fine
as it shows the average values and it'd be gone eventually.

Subject: [PATCH 0174/1480] perf stat: Display event stats using aggr counts

Now aggr counts are ready for use.  Convert the display routines to use
the aggr counts and update the shadow stat with them.  It doesn't need
to aggregate counts or collect aliases anymore during the display.  Get
rid of now unused struct perf_aggr_thread_value.

Note that there's a difference in the display order among the aggr mode.
For per-core/die/socket/node aggregation, it shows relevant events in
the same unit together, whereas global/thread/no aggregation it shows
the same events for different units together.  So it still uses separate
codes to display them due to the ordering.

One more thing to note is that it breaks per-core event display for now.
The next patch will fix it to have identical output as of now.

Subject: [PATCH 0175/1480] perf stat: Display percore events properly

The recent change in the perf stat broke the percore event display.
Note that the aggr counts are already processed so that the every
sibling thread in the same core will get the per-core counter values.

Check percore evsels and skip the sibling threads in the display.

Subject: [PATCH 0176/1480] perf stat: Remove unused perf_counts.aggr field

The aggr field in the struct perf_counts is to keep the aggregated value
in the AGGR_GLOBAL for the old code.  But it's not used anymore.

Subject: [PATCH 0183/1480] perf scripts python: intel-pt-events.py: Add
 ability interleave output

Intel PT timestamps are not provided for every branch, let alone every
instruction, so there can be many samples with the same timestamp. With
per-cpu contexts, decoding is done for each CPU in turn, which can make it
difficult to see what is happening on different CPUs at the same time.
Currently the interleaving from perf script --itrace=i0ns is quite coarse
grained. There are often long stretches executing on one CPU and nothing on
another.

Some people are interested in seeing what happened on multiple CPUs before
a crash to debug races etc.

To improve perf script interleaving for parallel execution, the
intel-pt-events.py script has been enhanced to enable interleaving the
output with the same timestamp from different CPUs. It is understood that
interleaving is not perfect or causal.

Add parameter --interleave [<n>] to interleave sample output for the same
timestamp so that no more than n samples for a CPU are displayed in a row.
'n' defaults to 4. Note this only affects the order of output, and only
when the timestamp is the same.

Example:

  $ perf script intel-pt-events.py --insn-trace --interleave 3

 As mentioned above, it is easy to capture too much data.  One way to limit the
 data captured is to use 'snapshot' mode which is explained further below.

Subject: [PATCH 0184/1480] perf test: Do not use instructions:u explicitly

I think it's to support non-root user tests.  But perf record can handle
the case and fall back to a software event (cpu-clock).  Practically this
would affect when it's run on a VM, but it seems no reason to prevent running
the test in the guest.

Subject: [PATCH 0186/1480] perf test: Use a test program in 'perf record'
 tests

If the system has cc it could build a test program with two threads
and then use it for more detailed testing.  Also it accepts an option
to run a thread forever to ensure multi-thread runs.

If cc is not found, it falls back to use the default value 'true'.

Subject: [PATCH 0187/1480] perf test: Wait for a new thread when testing
 --per-thread record

Just running the target program is not enough to test multi-thread
target because it'd be racy perf vs target startup.  I used the
initial delay but it cannot guarantee for perf to see the thread.

Instead, use wait_for_threads helper from shell/lib/waiting.sh to make
sure it starts the sibling thread first.  Then perf record can use -p
option to profile the target process.

 tests

Add system wide recording test with the same pattern.  It'd skip the
test when it fails to run 'perf record'.

For system-wide mode, it needs to avoid build-id collection and
synthesis because the test only cares about the test program and kernel
would generate the necessary events as the process starts.

The --threads option changed the 'perf record' behavior significantly,
so it'd be nice if we test it separately.  Add --threads options with
different argument in each test supported and check the result.

Also update the cleanup routine because threads recording produces data
in a directory.

Subject: [PATCH 0191/1480] perf test: Do not set TEST_SKIP for record subtests

It now has 4 sub tests and at least one of them should run.

But once the TEST_SKIP (= 2) return value is set, it won't be
overwritten unless there's a failure.  I think we should return success
when one or more tests are skipped but the remaining subtests are
passed.

So update the test code not to set the err variable when it skips
the test.

Subject: [PATCH 0192/1480] perf tools: Fix "kernel lock contention analysis"
 test by not printing warnings in quiet mode

Especially when CONFIG_LOCKDEP and other debug configs are enabled,
Perf can print the following warning when running the "kernel lock
contention analysis" test:

  Warning:
  Processed 1378918 events and lost 4 chunks!

  Check IO/CPU overload!

  Warning:
  Processed 4593325 samples and lost 70.00%!

The test already supplies -q to run in quiet mode, so extend quiet mode
to perf_stdio__warning() and also ui__warning() for consistency.

This fixes the following failure due to the extra lines counted:

  perf test "lock cont" -vvv

  82: kernel lock contention analysis test                            :
  --- start ---
  test child forked, pid 3125
  Testing perf lock record and perf lock contention
  [Fail] Recorded result count is not 1: 9
  test child finished with -1
  ---- end ----
  kernel lock contention analysis test: FAILED!

Fixes: ec685de25b6718f8 ("perf test: Add kernel lock contention test")

Subject: [PATCH 0193/1480] perf tools: Make quiet mode consistent between
 tools

Use the global quiet variable everywhere so that all tools hide warnings
in quiet mode and update the documentation to reflect this.

'perf probe' claimed that errors are not printed in quiet mode but I
don't see this so remove it from the docs.

Subject: [PATCH 0195/1480] bus: mhi: host: Use mhi_soc_reset() API in place of
 register write

Currently, a direct register write is used when ramdump collection
in panic path occurs. Replace that with new mhi_soc_reset() API
such that a controller defined reset() function is exercised if
one is present and the regular SOC reset is done if it is not.

Subject: [PATCH 0196/1480] bus: mhi: host: Fix race between channel
 preparation and M0 event

There is a race condition where mhi_prepare_channel() updates the
read and write pointers as the base address and in parallel, if
an M0 transition occurs, the tasklet goes ahead and rings
doorbells for all channels with a delta in TRE rings assuming
they are already enabled. This causes a null pointer access. Fix
it by adding a channel enabled check before ringing channel
doorbells.

Subject: [PATCH 0215/1480] Revert "staging: r8712u: Tracking kmemleak false
 positives."

This reverts commit 5d3da4a20a271e3cf5496a50cbb8118aa019374f.

This commit annotated false positive for kmemleak. The reasoning is that
the buffers are freed when the driver is unloaded. However, there is
actually potential memory leak when probe fails.

The function _r8712_init_recv_priv() and also r8712_init_recv_priv()
just returns silently if they fail to allocate memory. Change their
return type to int and add necessary checks and handling if they return
-ENOMEM

Subject: [PATCH 0217/1480] staging: rtl8712: check for return value of
 _r8712_init_xmit_priv()

The return value of _r8712_init_xmit_priv() is never checked and the driver
always continue execution as if all is well. This will cause problems
if, for example, buffers cannot be allocated and the driver continue and
use those buffers.

Check for return value of _r8712_init_xmit_priv() and return error (if any)
during probing.

Subject: [PATCH 0218/1480] staging: rtl8712: fix potential memory leak

In r8712_init_drv_sw(), whenever any function call returns error, it is
returned immediately without properly cleaning up the other successfully
executed functions. This can cause memory leak.

Instead of return immediately, free all the allocated buffers first.

Subject: [PATCH 0221/1480] staging: r8188eu: make on_action_public static void

The on_action_public function is called only by OnAction. This function
also lives in rtw_mlme_ext.c and does not check the return value from
on_action_public.

We can make on_action_public a static void function.

The ret variable is no longer needed if we don't return a value. It can
be removed.

OnAction_p2p has a switch-case statement where only a single case is
handled. Use if instead, this makes the code shorter and easier to read.

Use the struct mgmt to read the action_code. This is much simpler than
parsing the message ourselves.

Add a comment about reading the action code. All members of the action
enum start with an action_code byte. It does not matter which member we
use.

Subject: [PATCH 0229/1480] staging: r8188eu: remove return value from
 on_action_public_default

The only caller of on_action_public_default does not check the return
value. We can make it a void function.

Subject: [PATCH 0230/1480] staging: r8188eu: rtw_action_public_decache's token
 is a u8

Both callers of rtw_action_public_decache pass a u8 value for the token
parameter. We can change token from s32 to u8 and remove the code for
token < 0.

Subject: [PATCH 0232/1480] coresight: etm4x: add CPU hotplug support for
 probing

etm4x devices cannot be successfully probed when their CPU is offline.
For example, when booting with maxcpus=n, ETM probing will fail on
CPUs >n, and the probing won't be reattempted once the CPUs come
online. This will leave those CPUs unable to make use of ETM.

This change adds a mechanism to delay the probing if the corresponding
CPU is offline, and to try it again when the CPU comes online.

Subject: [PATCH 0243/1480] perf test: Parse events workaround for dash/minus

Skip an event configuration for event names with a dash/minus in them.
Events with a dash/minus in their name cause parsing issues as legacy
encoding of events would use a dash/minus as a separator.

The parser separates events with dashes into prefixes and suffixes and
then recombines them. Unfortunately if an event has part of its name
that matches a legacy token then the recombining fails.

This is seen for branch-brs where branch is a legacy token. branch-brs
was introduced to sysfs in:

  https://lore.kernel.org/all/20220322221517.2510440-5-eranian@google.com/

The failure is shown below as well as the workaround to use a config
where the dash/minus isn't treated specially:

```
  $ perf stat -e branch-brs true
  event syntax error: 'branch-brs'
                             \___ parser error

  $ perf stat -e cpu/branch-brs/ true

   Performance counter stats for 'true':

              46,179      cpu/branch-brs/
```

Subject: [PATCH 0245/1480] perf lock contention: Check --max-stack option

The --max-stack option is used to allocate the BPF stack map and stack
trace array in the userspace.  Check the value properly before using.
Practically it cannot be greater than the sysctl_perf_event_max_stack.

We can dynamically allocate instead.  While at it, simplify the error

Subject: [PATCH 0247/1480] perf lock contention: Increase default stack skip
 to 4

In most configurations, it works well with skipping 4 entries by
default.  If some systems still have 3 BPF internal stack frames,
the next frame should be in a lock function which will be skipped
later when it tries to find a caller.  So increasing to 4 won't
affect such systems too.

With --stack-skip=0, I can see something like this:

Content-Transfer-Encoding: 8bit

The unlabelled registers NPCM_I2CCTL4 to NPCM_I2CSCLHT overlap with the
bank 1 registers below, and they are accessed after selecting bank 0, so
they clearly belong to bank 0.

Move them together with the other bank 0 registers, and move the
unrelated definition of npcm_i2caddr down to keep the banked registers
in one piece.

Subject: [PATCH 0252/1480] i2c: npcm7xx: Annotate register field definitions
 with longer names
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

To make the code easier to understand, add longer names to the
definitions of register fields. These longer names are based on source
code published by DELL/AESS for WPCM450, but should apply just as well
to NPCM7xx and NPCM8xx.

Subject: [PATCH 0255/1480] tty: evh_bytechan: Replace NO_IRQ by 0

NO_IRQ is used to check the return of irq_of_parse_and_map().

On some architecture NO_IRQ is 0, on other architectures it is -1.

irq_of_parse_and_map() returns 0 on error, independent of NO_IRQ.

So use 0 instead of using NO_IRQ.

We can use ether_addr_equal instead of memcmp in
update_recvframe_phyinfo_88e for comparing the incoming frame's
destination address with our local address.

Both struct ieee80211_hdr and struct eeprom_priv's mac_addr component are
2-byte aligned.

Subject: [PATCH 0260/1480] staging: r8188eu: use ether_addr_equal in OnAction

Use ether_addr_equal to compare two mac addresses in OnAction.

Both struct ieee80211_mgmt and struct eeprom_priv's mac_addr component
are 2-byte aligned.

Subject: [PATCH 0264/1480] staging: rtl8192u: remove unnecessary function
 implementation

This driver is a single standalone driver and does not have any loading
dependencies on another associated drivers. The build results in one
single .ko object. The current implementation of the function
ieee80211_tkip_null simply returns back to the caller without any useful
instruction executions. It does not lead to auto-loading of any other
associated modules as the initial design implementation appears to be.

Hence the call to ieee80211_tkip_null() and its implementation is
unnecessary and should be removed.

The function rtw_free_stainfo() returns always _SUCCESS and none of
its callers uses the return value. We can safely make the function
void. Yet another tiny step towards getting rid of _FAIL / _SUCCESS.

Subject: [PATCH 0267/1480] staging: wlan-ng: Remove unused struct wlan_ie_ssid
 references

Pointer reference to struct wlan_ie_ssid is added as a member variable
to 5 different structures. However, these references are never used.
Remove such unused struct references. The cleanup also renders the
struct useless; so remove it as well.
Issue identified as part of coccicheck based code analysis.

Subject: [PATCH 0274/1480] staging: r8188eu: convert rtw_setdatarate_cmd to
 correct error semantics

Convert rtw_setdatarate_cmd function to use proper error return codes
rather than _SUCCESS and _FAIL, and a simpler 'return 0;' style. For now,
wrap rtw_enqueue_cmd call and return -EPERM if it fails, as converting
this function makes more sense later on due to its large number of callers.

Also change rtw_wx_set_rate function to pass through the proper error
code rather than just 0 or -1.

Subject: [PATCH 0279/1480] tty: Allow TIOCSTI to be disabled

TIOCSTI continues its long history of being used in privilege escalation
attacks[1]. Prior attempts to provide a mechanism to disable this have
devolved into discussions around creating full-blown LSMs to provide
arbitrary ioctl filtering, which is hugely over-engineered -- only
TIOCSTI is being used this way. 3 years ago OpenBSD entirely removed
TIOCSTI[2], Android has had it filtered for longer[3], and the tools that
had historically used TIOCSTI either do not need it, are not commonly
built with it, or have had its use removed.

Provide a simple CONFIG and global sysctl to disable this for the system
builders who have wanted this functionality for literally decades now,
much like the ldisc_autoload CONFIG and sysctl.

Subject: [PATCH 0280/1480] tty: serial: introduce transmit helpers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Many serial drivers do the same thing:
* send x_char if set
* keep sending from the xmit circular buffer until either
  - the loop reaches the end of the xmit buffer
  - TX is stopped
  - HW fifo is full
* check for pending characters and:
  - wake up tty writers to fill for more data into xmit buffer
  - stop TX if there is nothing in the xmit buffer

The only differences are:
* how to write the character to the HW fifo
* the check of the end condition:
  - is the HW fifo full?
  - is limit of the written characters reached?

So unify the above into two helpers:
* uart_port_tx_limited() -- it performs the above taking the written
  characters limit into account, and
* uart_port_tx() -- the same as above, except it only checks the HW
  readiness, not the characters limit.

The HW specific operations (as stated as "differences" above) are passed
as arguments to the macros. They are:
* tx_ready -- returns true if HW can accept more data.
* put_char -- write a character to the device.
* tx_done -- when the write loop is done, perform arbitrary action
  before potential invocation of ops->stop_tx() happens.

Note that the above are macros. This means the code is generated in
place and the above 3 arguments are "inlined". I.e. no added penalty by
generating call instructions for every single character. Nor any
indirect calls. (As in some previous versions of this patchset.)

From: "Jiri Slaby (SUSE)" <jirislaby@kernel.org>
Date: Tue, 4 Oct 2022 12:49:27 +0200
Subject: [PATCH 0282/1480] tty: serial: use uart_port_tx_limited()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

uart_port_tx_limited() is a new helper to send characters to the device.
Use it in these drivers.

mux.c also needs to define tx_done(). But I'm not sure if the driver
really wants to wait for all the characters to dismiss from the HW fifo
at this code point. Hence I marked this as FIXME.

Subject: [PATCH 0283/1480] tty: serial: qcom-geni-serial: Add support for
 Hibernation feature

Added changes to support the hibernation feature for serial UART.
Added support for freeze, restore and thaw callbacks to put the
device into hibernation.

Subject: [PATCH 0284/1480] serial: 8250: 8250_omap: Support native RS485
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Recent TI Sitara SoCs such as AM64/AM65 have gained the ability to
automatically assert RTS when data is transmitted, obviating the need
to emulate this functionality in software.

The feature is controlled through new DIR_EN and DIR_POL bits in the
Mode Definition Register 3.  For details see page 8783 and 8890 of the
AM65 TRM:  https://www.ti.com/lit/ug/spruid7e/spruid7e.pdf

Subject: [PATCH 0329/1480] serial: tegra: Read DMA status before terminating
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Read the DMA status before terminating the DMA, as doing so deletes
the DMA desc.

Also, to get the correct transfer status information, pause the DMA
using dmaengine_pause() before reading the DMA status.

Subject: [PATCH 0335/1480] dt-bindings: serial: ingenic: Add support for the
 JZ4750/55 SoCs

These SoCs UART block are the same as JZ4725b' one, the difference is
outside of the block - it is in the clock generation unit (CGU).
The difference requires to make a quirk for early console init.

Subject: [PATCH 0336/1480] serial: 8250/ingenic: Add support for the
 JZ4750/JZ4755

JZ4750/55/60 (but not JZ4760b) have an optional /2 divider between the
EXT oscillator and some peripherals including UART, which will
be enabled if using a 24 MHz oscillator, and disabled when
using a 12 MHz oscillator.

This behavior relies on hardware differences: most boards (if not all)
with those SoCs have 12 or 24 MHz oscillators but many peripherals want
12Mhz to operate properly (AIC and USB-PHY at least).

The 16MHz threshold looks arbitrary but used in vendor's bootloader code
for enable the divider.

The patch doesn't affect JZ4760's behavior as it is subject for another
patchset with re-classification of all supported ingenic UARTs.

Subject: [PATCH 0337/1480] tty: serial: imx: Handle RS485 DE signal active
 high

The default polarity of RS485 DE signal is active high. This driver does
not handle such case properly. Currently, when a pin is multiplexed as a
UART CTS_B on boot, this pin is pulled HIGH by the i.MX UART CTS circuit,
which activates DE signal on the RS485 transceiver and thus behave as if
the RS485 was transmitting data, so the system blocks the RS485 bus when
it starts and until user application takes over. This behavior is not OK.
The problem consists of two separate parts.

First, the i.MX UART IP requires UCR1 UARTEN and UCR2 RXEN to be set for
UCR2 CTSC and CTS bits to have any effect. The UCR2 CTSC bit permits the
driver to set CTS (RTS_B or RS485 DE signal) to either level sychronous
to the internal UART IP clock. Compared to other options, like GPIO CTS
control, this has the benefit of being synchronous to the UART IP clock
and thus without glitches or bus delays. The reason for the CTS design
is likely because when the Receiver is disabled, the UART IP can never
indicate that it is ready to receive data by assering CTS signal, so
the CTS is always pulled HIGH by default.

When the port is closed by user space, imx_uart_stop_rx() clears UCR2
RXEN bit, and imx_uart_shutdown() clears UCR1 UARTEN bit. This disables
UART Receiver and UART itself, and forces CTS signal HIGH, which leads
to the RS485 bus being blocked because RS485 DE is incorrectly active.

The proposed solution for this problem is to keep the Receiver running
even after the port is closed, but in loopback mode. This disconnects
the RX FIFO input from the RXD external signal, and since UCR2 TXEN is
cleared, the UART Transmitter is disabled, so nothing can feed data in
the RX FIFO. Because the Receiver is still enabled, the UCR2 CTSC and
CTS bits still have effect and the CTS (RS485 DE) control is retained.

Note that in case of RS485 DE signal active low, there is no problem and
no special handling is necessary. The CTS signal defaults to HIGH, thus
the RS485 is by default set to Receive and the bus is not blocked.

Note that while there is the possibility to control CTS using GPIO with
either CTS polarity, this has the downside of not being synchronous to
the UART IP clock and thus glitchy and susceptible to slow DE switching.

Second, on boot, before the UART driver probe callback is called, the
driver core triggers pinctrl_init_done() and configures the IOMUXC to
default state. At this point, UCR1 UARTEN and UCR2 RXEN are both still
cleared, but UART CTS_B (RS485 DE) is configured as CTS function, thus
the RTS signal is pulled HIGH by the UART IP CTS circuit.

One part of the solution here is to enable UCR1 UARTEN and UCR2 RXEN and
UTS loopback in this driver probe callback, thus unblocking the CTSC and
CTS control early on. But this is still too late, since the pin control
is already configured and CTS has been pulled HIGH for a short period
of time.

When Linux kernel boots and this driver is bound, the pin control is set
to special "init" state if the state is available, and driver can switch
the "default" state afterward when ready. This state can be used to set
the CTS line as a GPIO in DT temporarily, and a GPIO hog can force such
GPIO to LOW, thus keeping the RS485 DE line LOW early on boot. Once the
driver takes over and UCR1 UARTEN and UCR2 RXEN and UTS loopback are all
enabled, the driver can switch to "default" pin control state and control
the CTS line as function instead. DT binding example is below:

"
&gpio6 {
  rts-init-hog {
    gpio-hog;
    gpios = <5 0>;
    output-low;
    line-name = "rs485-de";
  };
};

&uart5 { /* DHCOM UART2 */
  pinctrl-0 = <&pinctrl_uart5>;
  pinctrl-1 = <&pinctrl_uart5_init>;
  pinctrl-names = "default", "init";
  ...
};
pinctrl_uart5_init: uart5-init-grp {
  fsl,pins = <
...
    MX6QDL_PAD_CSI0_DAT19__GPIO6_IO05       0x30b1
  >;
};

pinctrl_uart5: uart5-grp {
  fsl,pins = <
...
    MX6QDL_PAD_CSI0_DAT19__UART5_CTS_B      0x30b1
  >;
};
"

Subject: [PATCH 0342/1480] perf probe: Fix to avoid crashing if
 DW_AT_decl_file is NULL

Since clang generates DWARF5 which sets DW_AT_decl_file as 0,
dwarf_decl_file() thinks that is invalid and returns NULL.  In that case
'perf probe' SIGSEGVs because it doesn't expect a NULL decl_file.

This adds a dwarf_decl_file() return value check to avoid such SEGV with
clang generated DWARF5 info.

Without this, 'perf probe' crashes:

  $ perf probe -k $BIN_PATH/vmlinux -s $SRC_PATH -L vfs_read:10
  Segmentation fault
  $

With this, it just warns about it:

  $ perf probe -k $BIN_PATH/vmlinux -s $SRC_PATH -L vfs_read:10
  Debuginfo analysis failed.
    Error: Failed to show lines.
  $

Subject: [PATCH 0344/1480] perf probe: Fix to get declared file name from
 clang DWARF5

Fix to get the declared file name even if it uses file index 0
in DWARF5, using custom die_get_decl_file() function.

Actually, the DWARF5 standard says file index 0 of the DW_AT_decl_file
is invalid(1), but there is a discussion and maybe this will be updated
[2].

Anyway, clang generates such DWARF5 file for the linux kernel. Thus it
must be handled.

Without this, 'perf probe' returns an error:

   $ ./perf probe -k $BIN_PATH/vmlinux -s $SRC_PATH -L vfs_read:10
   Debuginfo analysis failed.
     Error: Failed to show lines.

With this, it can handle the case correctly:

  $ ./perf probe -k $BIN_PATH/vmlinux -s $SRC_PATH -L vfs_read:10
  <vfs_read@$SRC_PATH/fs/read_write.c:10>

       11         ret = rw_verify_area(READ, file, pos, count);
       12         if (ret)
                           return ret;

[1] DWARF5 specification 2.14 says "The value 0 indicates that no source file has been specified.")

Subject: [PATCH 0345/1480] perf build: Update to C standard to gnu11

C11 has become the standard for mainstream kernel development [1],
allowing it in the perf build enables libraries like stdatomic.h to be
assumed to be present. This came up in the context of [2].

Subject: [PATCH 0353/1480] USB: core: Change configuration warnings to notices

It has been pointed out that the kernel log messages warning about
problems in USB configuration and related descriptors are vexing for
users.  The warning log level has a fairly high priority, but the user
can do nothing to fix the underlying errors in the device's firmware.

To reduce the amount of useless information produced by tools that
filter high-priority log messages, we can change these warnings to
notices, i.e., change dev_warn() to dev_notice().  The same holds for
a few messages that currently use dev_err(): Unless they indicate a
failure that might make a device unusable (such as inability to
transfer a config descriptor), change them to dev_notice() also.

Subject: [PATCH 0354/1480] usb: core: Use kstrtobool() instead of strtobool()

strtobool() is the same as kstrtobool().
However, the latter is more used within the kernel.

In order to remove strtobool() and slightly simplify kstrtox.h, switch to
the other function name.

While at it, include the corresponding header file (<linux/kstrtox.h>)

From 14e4b9f4289aed2c8d4858cd750748041b6c434f Mon Sep 17 00:00:00 2001

Subject: [PATCH 0356/1480] perf trace: Raw augmented syscalls fix libbpf 1.0+
 compatibility

Don't use deprecated and now broken map style. Avoid use of
tools/perf/include/bpf/bpf.h and use the more regular BPF headers.

Committer notes:

Add /usr/include to the include path so that bpf/bpf_helpers.h can be
found, remove sys/socket.h, adding the sockaddr_storage definition, also
remove stdbool.h, both were preventing building the
augmented_raw_syscalls.c file with clang, revisit later.

Testing it:

Asking for syscalls that have string arguments:

  # perf trace -e ~acme/git/perf/tools/perf/examples/bpf/augmented_raw_syscalls.c,string --max-events 10

Don't use deprecated and now broken map style. Avoid use of

Switch to raw_syscalls:sys_enter to avoid the evlist being empty and
fixing generating output.

Date: Wed, 2 Nov 2022 21:54:35 -0700
Subject: [PATCH 0358/1480] perf trace: empty fix libbpf 1.0+ compatibility

Avoid use of tools/perf/include/bpf/bpf.h and use the more regular BPF
headers.  Add raw_syscalls:sys_enter to avoid the evlist being empty.

Committer testing:

  # time perf trace -e ~acme/git/perf/tools/perf/examples/bpf/empty.c sleep 5

  real	0m5.697s
  user	0m0.217s
  sys	0m0.453s
  #

I.e. it sets up everything successfully (use -v to see the details) and
filters out all syscalls, then exits when the workload (sleep 5)
finishes.

From 3cd65616f607cd3769647e2e0490e4048c0f289e Mon Sep 17 00:00:00 2001
From: Arnaldo Carvalho de Melo <acme@redhat.com>
Date: Fri, 4 Nov 2022 11:15:51 -0300
Subject: [PATCH 0361/1480] perf examples bpf: Remove augmented_syscalls.c, the
 raw_syscalls one should be used instead

The attempt at using BPF to copy syscall pointer arguments to show them
like strace does started with sys_{enter,exit}_SYSCALL_NAME tracepoints,
in tools/perf/examples/bpf/augmented_syscalls.c, but then achieving this
result using raw_syscalls:{enter,exit} and BPF tail calls was deemed
more flexible.

The 'perf trace' codebase was adapted to using it while trying to
continue supporting the old style per-syscall tracepoints, which at some
point became too unwieldly and now isn't working properly.

So lets scale back and concentrate on the augmented_raw_syscalls.c
model on the way to using BPF skeletons.

For the same reason remove the etcsnoop.c example, that used the
old style per-tp syscalls just for the 'open' and 'openat' syscalls,
looking at the pathnames starting with "/etc/", we should be able
to do this later using filters, after we move to BPF skels.

The augmented_raw_syscalls.c one continues to work, now with libbpf 1.0,
after Ian work on using the libbpf map style:

  # perf trace -e ~acme/git/perf/tools/perf/examples/bpf/augmented_raw_syscalls.c,open* --max-events 4
     0.000 ping/194815 openat(dfd: CWD, filename: "/etc/hosts", flags: RDONLY|CLOEXEC) = 5
    20.225 systemd-oomd/972 openat(dfd: CWD, filename: "/proc/meminfo", flags: RDONLY|CLOEXEC) = 12
    20.285 abrt-dump-jour/1371 openat(dfd: CWD, filename: "/var/log/journal/d6a97235307247e09f13f326fb607e3c/system.journal", flags: RDONLY|CLOEXEC|NONBLOCK) = 21

  #

This is using this:

  # cat ~/.perfconfig
  [trace]
	show_zeros = yes
	show_duration = no
	no_inherit = yes
	args_alignment = 40

Subject: [PATCH 0362/1480] perf bpf: Rename perf_include_dir to
 libbpf_include_dir

As this is where we expect to find bpf/bpf_helpers.h, etc.

This needs more work to make it follow LIBBPF_DYNAMIC=1 usage, i.e. when
not using the system libbpf it should use the headers in the in-kernel
sources libbpf in tools/lib/bpf.

We need to do that anyway to avoid this mixup system libbpf and
in-kernel files, so we'll get this sorted out that way.

And this also may become moot as we move to using BPF skels for this
feature.

Subject: [PATCH 0363/1480] bus: mhi: host: pci_generic: add support for
 sc8280xp-crd SDX55 variant

The SC8280XP Compute Reference Design (CRD) has an on-PCB SDX55 modem
which uses MBIM.

The exact channel configuration is not known but the Foxconn SDX55
configuration allows the modem to be used so reuse that one for now.

Subject: [PATCH 0364/1480] thunderbolt: Add wake on connect/disconnect on USB4
 ports

Wake on connect/disconnect is only supported while runtime suspend for
now, which is obviously necessary. It is also not inherently desired for
the system to wakeup on Thunderbolt/USB4 hot plug events. However, we
can still make user in control of waking up the system in the events of
hot plug/unplug.

This patch adds 'wakeup' attribute under 'usb4_portX/power' sysfs
attribute and only enables wakes on connect/disconnect to the respective
port when 'wakeup' is set to 'enabled'. The attribute is set to
'disabled' by default.

Subject: [PATCH 0365/1480] bus: mhi: host: pci_generic: Add HP variant of
 T99W175

The Foxconn T99W175 modem has an HP variant, which has
the following output from lspci:

01:00.0 Wireless controller [0d40]: Device 03f0:0a6c

It also has some HP-specific serial numbers on the
metal case. It works well with this driver, so add
support for this to the pci_generic driver.

Subject: [PATCH 0366/1480] perf trace: Add BPF augmenter to
 perf_event_open()'s 'struct perf_event_attr' arg

Using BPF for that, doing a cleverish reuse of perf_event_attr__fprintf(),
that really needs to be turned into __snprintf(), etc.

But since the plan is to go the BTF way probably use libbpf's
btf_dump__dump_type_data().

Example:

[root@quaco ~]# perf trace -e ~acme/git/perf/tools/perf/examples/bpf/augmented_raw_syscalls.c,perf_event_open --max-events 10 perf stat --quiet sleep 0.001

build target:

Subject: [PATCH 0369/1480] staging: rtl8192e: Use min_t/max_t macros for
 variable comparison

Simplify code by using min_t and max_t helper macros in place of lengthy
if/else block oriented logical evaluation and value assignment. This
issue is identified by coccicheck using the minmax.cocci file.

Use the *_t variants of min/max macros to avoid compiler warnings about
data typecast.
Also, use u32 as type for min_t macro to avoid any truncation of data
associated with enum constant HT_AGG_SIZE_32K.

Change return type of rtw_set_802_11_disassociate to void. This function
always returns 'true' no matter what, so there is no need to return a
value, and no need to check for it in the two call sites within
rtw_wx_set_mlme. Also, as we are no longer using ret in rtw_wx_set_mlme
except as the return value, just remove it and return 0 directly.

Subject: [PATCH 0374/1480] staging: rtl8192e: Fix divide fault when
 calculating beacon age

When the configuration parameter CONFIG_HZ is less that 100, the compiler
generates an error as follows:

../drivers/staging/rtl8192e/rtllib_wx.c: In function 'rtl819x_translate_scan':
../drivers/staging/rtl8192e/rtllib_wx.c:220:57: warning: division by zero [-Wdiv-by-zero]
  220 |      (jiffies - network->last_scanned) / (HZ / 100));
      |                                                         ^
In file included from ../include/linux/skbuff.h:45,
                 from ../include/linux/if_ether.h:19,
                 from ../include/linux/etherdevice.h:20,
                 from ../drivers/staging/rtl8192e/rtllib_wx.c:18:
../drivers/staging/rtl8192e/rtllib_wx.c: In function 'rtllib_wx_get_scan':

  261 |      (jiffies - network->last_scanned) /
      |

In fact, is HZ is not a multiple of 100, the calculation will be wrong,
but it will compile correctly.

The fix is to get rid of the (HZ / 100) portion. To decrease any round-off
errors, the compiler is forced to perform the 100 * jiffies-difference
before dividing by HZ. This patch is only compile tested.

utilised. Replace the struct declaration and implementation by an
equivalent variable similar to the only used struct member variable.
While in there, update the macro mixed case names to uppercase style.
The resultant code is simpler and is easy to maintain.

Subject: [PATCH 0379/1480] staging: r8188eu: don't store addba request

There's no need to store an incoming addba request in struct
mlme_ext_info. We only need the addba request to copy some of its fields
into our addba response.

It's simpler to pass the incoming request's management frame to
issue_action_BA as an additional parameter. issue_action_BA can then
extract the required fields. If issue_action_BA prepares a request rather
than a response, the caller sets the parameter for the incoming request to
NULL.

Subject: [PATCH 0383/1480] staging: r8188eu: remove state checks in
 rtw_led_control

There's no need to check for bSurpriseRemoved or bDriverStopped in the
rtw_led_control function. This function schedules a delayed worker which
calls SwLedOn or SwLedOff (or the function calls SwLedOff directly).

SwLedOn and SwLedOff check bDriverStopped themselves or they initiate a
USB control transfer via usb_write, where bSurpriseRemoved is checked.

The sequence of function calls is

For each fragment, rtw_write_port is called. This function checks

Subject: [PATCH 0389/1480] staging: r8188eu: simplify complex pointer casting

Pointers to structures udphdr and dhcpMessage are derived by casting
adjacent pointers with size_t. Such typecast of pointer using size_t
is not preferred. The code looks complex and delicate. Simplify such
casting by utilizing generic "void *" casting.

Make it possible to probe the GPIO VBUS detection driver
from the device tree compatible for GPIO USB B connectors.

Since this driver is using the "gpio-usb-b-connector"
compatible, it is important to discern it from the role
switch connector driver (which does not provide a phy),
so we add some Kconfig text and depend on !USB_CONN_GPIO.

Subject: [PATCH 0395/1480] usb: dwc3: gadget: Reduce TRB IOC settings

When the TRB ring is full, the dwc3 driver must make sure that there's
at least 1 TRB with Interrupt On Completion (IOC) set to notify of
available TRBs.

The current logic just sets the TRB's IOC whenever we run out of TRBs,
but it doesn't consider that there may be other TRBs with IOC/LST set
already. This creates more events and unnecessary delay from interrupt
handling. Only forcefully set IOC when we run out of TRBs and none of
the TRBs in the TRB ring has had IOC set.

Subject: [PATCH 0396/1480] usb: core: stop USB enumeration if too many retries

When a broken USB accessory connects to a USB host, usbcore might
keep doing enumeration retries. If the host has a watchdog mechanism,
the kernel panic will happen on the host.

This patch provides an attribute early_stop to limit the numbers of retries
for each port of a hub. If a port was marked with early_stop attribute,
unsuccessful connection attempts will fail quickly. In addition, if an
early_stop port has failed to initialize, it will ignore all future
connection events until early_stop attribute is clear.

Subject: [PATCH 0397/1480] perf probe: Fix to get the DW_AT_decl_file and
 DW_AT_call_file as unsinged data

DWARF version 5 standard Sec 2.14 says that

  Any debugging information entry representing the declaration of an object,
  module, subprogram or type may have DW_AT_decl_file, DW_AT_decl_line and
  DW_AT_decl_column attributes, each of whose value is an unsigned integer
  constant.

So it should be an unsigned integer data. Also, even though the standard
doesn't clearly say the DW_AT_call_file is signed or unsigned, the
elfutils (eu-readelf) interprets it as unsigned integer data and it is
natural to handle it as unsigned integer data as same as DW_AT_decl_file.
This changes the DW_AT_call_file as unsigned integer data too.

Fixes: 3f4460a28fb2f73d ("perf probe: Filter out redundant inline-instances")

Convert the usb251xb hub DT bindings from text to yaml schema so it is

Adjust the example to describe two different hubs at different I2C bus
addresses, to avoid I2C address collission in the example.

This driver often takes on the order of 8ms to start, but every little

race with, nor racy access to shared state with other drivers, so this
should be a relatively low risk change.

This driver was pinpointed as part of a survey of top slowest initcalls
(i.e., are built in, and probing synchronously) on a lab of ChromeOS

Subject: [PATCH 0406/1480] usb: gadget: aspeed: fix buffer overflow

In ast_vhub_epn_handle_ack() when the received data length exceeds the
buffer, it does not check the case and just copies to req.buf and cause
a buffer overflow, kernel oops on this case.

This issue could be reproduced on a BMC with an OS that enables the
lan over USB:
1. In OS, enable the usb eth dev, verify it pings the BMC OK;
2. In OS, set the usb dev mtu to 2000. (Default is 1500);
3. In OS, ping the BMC with `-s 2000` argument.

The BMC kernel will get oops with below logs:

    skbuff: skb_over_panic: text:8058e098 len:2048 put:2048 head:84c678a0 data:84c678c2 tail:0x84c680c2 end:0x84c67f00 dev:usb0
    ------------[ cut here ]------------
    kernel BUG at net/core/skbuff.c:113!
    Internal error: Oops - BUG: 0 [#1] ARM
    CPU: 0 PID: 0 Comm: swapper Not tainted 5.15.69-c9fb275-dirty-d1e579a #1
    Hardware name: Generic DT based system
    PC is at skb_panic+0x60/0x6c
    LR is at irq_work_queue+0x6c/0x94

Fix the issue by checking the length and set `-EOVERFLOW`.

Tested: Verify the BMC kernel does not get oops in the above case, and
the usb ethernet gets RX packets errors instead.

Subject: [PATCH 0409/1480] usb: chipidea: core: wrap ci_handle_power_lost()
 with CONFIG_PM_SLEEP

If CONFIG_PM_SLEEP is not set, the following error will be shown up
when build kernel:
    error: 'ci_handle_power_lost' defined but not used.

This will move ci_handle_power_lost() to an area wrapped by
CONFIG_PM_SLEEP.

Subject: [PATCH 0410/1480] tools: usb: ffs-aio-example: Fix build error with
 aarch64-*-gnu-gcc toolchain(s)

The tools/usb/aio_simple.c file when cross-compiled with
aarch64-*-gnu-gcc toolchain(s) leads to the following errors:

  aio_simple.c:30:10: fatal error: endian.h: No such file or directory
  30 | #include <endian.h>
      |          ^~~~~~~~~~

  aio_simple.c:88:14: note: (near initialization for
                      'descriptors.fs_count')
  aio_simple.c:110:14: error: initializer element is not constant
  110 |  .hs_count = htole32(3),
      |              ^~~~~~~
  aio_simple.c:110:14: note: (near initialization for
                      'descriptors.hs_count')
  aio_simple.c:124:22: error: initializer element is not constant
  124 |    .wMaxPacketSize = htole16(512),
      |                      ^~~~~~~
  aio_simple.c:124:22: note: (near initialization for
                       'descriptors.hs_descs.bulk_sink.wMaxPacketSize')

Fix these compilation issues by:
 - Switching to _DEFAULT_SOURCE:
    _BSD_SOURCE is deprecated and gives a build warning. Let's use
    _DEFAULT_SOURCE instead.
 - Currently this file uses library htole16/32 function calls.
   Replace these with equivalent 'cpu_to_le16/32' calls.

Subject: [PATCH 0411/1480] usb: fotg210: Collect pieces of dual mode
 controller

The Faraday FOTG210 is a dual-mode OTG USB controller that can
act as host, peripheral or both. To be able to probe from one
hardware description and to follow the pattern of other dual-
mode controllers such as MUSB or MTU3 we need to collect the
two, currently completely separate drivers in the same
directory.

After this, users need to select the main symbol USB_FOTG210
and then each respective subdriver. We pave the road to
compile both drivers into the same kernel and select the
one we want to use at probe() time, and possibly add OTG
support in the end.

This patch doesn't do much more than create the new symbol
and collect the drivers in one place. We also add a comment
for the section of dual-mode controllers in the Kconfig
file so people can see what these selections are about.

Also add myself as maintainer as there has been little
response on my patches to these drivers.

Subject: [PATCH 0412/1480] usb: fotg210: Compile into one module

It is since ages perfectly possible to compile both of these
modules into the same kernel, which makes no sense since it
is one piece of hardware.

Compile one module named "fotg210.ko" for both HCD and UDC
drivers by collecting the init calls into a fotg210-core.c
file and start to centralize things handling one and the same
piece of hardware.

Stub out the initcalls if one or the other part of the driver
was not selected.

Tested by compiling one or the other or both of the drivers
into the kernel and as modules.

Subject: [PATCH 0413/1480] usb: fotg210: Select subdriver by mode

Check which mode the hardware is in, and selecte the peripheral
driver if the hardware is in explicit peripheral mode, otherwise
select host mode.

This should solve the immediate problem that both subdrivers
can get probed.

Subject: [PATCH 0414/1480] usb: musb: Add and use inline functions
 musb_{get,set}_state

Instead of manipulating musb->xceiv->otg->state directly, use the newly
introduced musb_get_state() and musb_set_state() inline functions.

Later, these inline functions will be modified to get rid of the
musb->xceiv dependency, which prevents the musb code from using the
generic PHY subsystem.

From 285f28bfed89a56ed619054f21125b0bd2f0d4d6 Mon Sep 17 00:00:00 2001

Subject: [PATCH 0415/1480] usb: musb: Add and use inline function
 musb_otg_state_string

The musb_otg_state_string() simply calls usb_otg_state_string().
This will make it easier to get rid of the musb->xceiv dependency later.

Subject: [PATCH 0418/1480] usb: musb: jz4740: Don't disable external hubs

The jz4740-musb driver does not really support OTG, so it has no reason
to disable external hubs, especially since it's a system-wide setting
and we don't want external hubs to be disabled for other USB host
controllers.

Subject: [PATCH 0421/1480] usb: gadget: u_ether: Do not make UDC parent of the
 net device

The UDC is not a suitable parent of the net device as the UDC can
change or vanish during the lifecycle of the ethernet gadget. This
can be illustrated with the following:

mkdir -p /sys/kernel/config/usb_gadget/mygadget
cd /sys/kernel/config/usb_gadget/mygadget
mkdir -p configs/c.1/strings/0x409
echo "C1:Composite Device" > configs/c.1/strings/0x409/configuration
mkdir -p functions/ecm.usb0
ln -s functions/ecm.usb0 configs/c.1/
echo "dummy_udc.0" > UDC
rmmod dummy_hcd

The 'rmmod' removes the UDC from the just created gadget, leaving
the still existing net device with a no longer existing parent.

Accessing the ethernet device with commands like:

ip --details link show usb0

will result in a KASAN splat:

Solve this by not setting the parent of the ethernet device.

Subject: [PATCH 0422/1480] usb: gadget: f_ecm: Always set current gadget in
 ecm_bind()

The gadget may change over bind/unbind cycles, so set it each time during
bind, not only the first time. Without it we get a use-after-free with
the following example:

cd /sys/kernel/config/usb_gadget/; mkdir -p mygadget; cd mygadget
mkdir -p configs/c.1/strings/0x409
echo "C1:Composite Device" > configs/c.1/strings/0x409/configuration
mkdir -p functions/ecm.usb0
ln -s functions/ecm.usb0 configs/c.1/
rmmod dummy_hcd
modprobe dummy_hcd

KASAN will complain shortly after the 'modprobe':

Subject: [PATCH 0423/1480] tty: Convert tty_buffer flags to bool
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The struct tty_buffer has flags which is only used for storing TTYB_NORMAL.
There is also a few quite confusing operations for checking the presense
of TTYB_NORMAL. Simplify things by converting flags to bool.

Despite the name remaining the same, the meaning of "flags" is altered
slightly by this change. Previously it referred to flags of the buffer
(only TTYB_NORMAL being used as a flag). After this change, flags tell
whether the buffer contains/should be allocated with flags array along
with character data array. It is much more suitable name that
TTYB_NORMAL was for this purpose, thus the name remains.

Subject: [PATCH 0425/1480] serial: 8250_dma: Rearm DMA Rx if more data is
 pending
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When DMA Rx completes, the current behavior is to just exit the DMA
completion handler without future actions. If the transfer is still
on-going, UART will trigger an interrupt and that eventually rearms the
DMA Rx. The extra interrupt round-trip has an inherent latency cost
that increases the risk of FIFO overrun. In such situations, the
latency margin tends to already be less due to FIFO not being empty.

Add check into DMA Rx completion handler to detect if LSR has DR (Data
Ready) still set. DR indicates there will be more characters pending
and DMA Rx can be rearmed right away to handle them.

Subject: [PATCH 0426/1480] serial: 8250_bcm7271: Fix error handling in
 brcmuart_init()

A problem about 8250_bcm7271 create debugfs failed is triggered with the
following log given:

 [  324.516635] debugfs: Directory 'bcm7271-uart' with parent '/' already present!

The reason is that brcmuart_init() returns platform_driver_register()
directly without checking its return value, if platform_driver_register()
failed, it returns without destroy the newly created debugfs, resulting
the debugfs of 8250_bcm7271 can never be created later.

 brcmuart_init()
   debugfs_create_dir() # create debugfs directory
   platform_driver_register()
     driver_register()
       bus_add_driver()
         priv = kzalloc(...) # OOM happened
   # return without destroy debugfs directory

Fix by removing debugfs when platform_driver_register() returns error.

Subject: [PATCH 0427/1480] serial: 8250: 8250_omap: Fix calculation of RS485
 delays
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Commit 801954d1210a ("serial: 8250: 8250_omap: Support native RS485")
calculates RS485 delays from the baudrate.  The baudrate is generated
with either a 16x or 13x divisor.  The divisor is set in the Mode
Definition Register 1 (MDR1).

The commit erroneously assumes that the register stores the divisor as
a bitmask and uses a logical AND to differentiate between 16x and 13x
divisors.  However the divisor is really stored as a 3-bit mode
(see lines 363ff in include/uapi/linux/serial_reg.h).

The logical AND operation is performed with UART_OMAP_MDR1_16X_MODE,
which is defined as 0x0 and hence yields false.  So the commit always
assumes a 13x divisor.  Fix by using an equal comparison.  This works
because we never set any of the other 5 bits in the register.  (They
pertain to IrDA mode, which is not supported by the driver).

n_gsm has a minimal protocol overhead of 7 bytes. The current code already
checks whether the configured MRU/MTU size is at least one byte more than
this.

Introduce the macro MIN_MTU to make this value more obvious.

Subject: [PATCH 0429/1480] tty: n_gsm: add parameters used with parameter
 negotiation

n_gsm is based on the 3GPP 07.010 and its newer version is the 3GPP 27.010.
See https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=1516
The changes from 07.010 to 27.010 are non-functional. Therefore, I refer to
the newer 27.010 here. Chapter 5.4.6.3.1 describes the encoding of the
parameter negotiation messages.

Add the parameters used there to 'gsm_mux' and 'gsm_dlci' and initialize both
according to the value ranges and recommended defaults defined in chapter 5.7.

Replace the use of the DLC default values from the 'gsm_mux' fields with the DLC
specific values from the 'gsm_dlci' fields where applicable.

The changes from 07.010 to 27.010 are non-functional. Therefore, I refer to
the newer 27.010 here. Chapter 5.1.8.1.1 describes the parameter negotiation
messages and parameters. Chapter 5.4.1 states that the default parameters
are to be used if no negotiation is performed. Chapter 5.4.6.3.1 describes
the encoding of the parameter negotiation message. The meaning of the
parameters and allowed value ranges can be found in chapter 5.7.

Add parameter negotiation support accordingly. DLCI specific parameter
configuration by the user requires additional ioctls. This is subject to
another patch.

Subject: [PATCH 0432/1480] drivers: staging: r8188eu: Fix
 sleep-in-atomic-context bug in rtw_join_timeout_handler

The rtw_join_timeout_handler() is a timer handler that
runs in atomic context, but it could call msleep().
As a result, the sleep-in-atomic-context bug will happen.
The process is shown below:

     (atomic context)
rtw_join_timeout_handler
 _rtw_join_timeout_handler
  rtw_do_join
   rtw_select_and_join_from_scanned_queue
    rtw_indicate_disconnect
     rtw_lps_ctrl_wk_cmd
      lps_ctrl_wk_hdl
       LPS_Leave
        LPS_RF_ON_check
         msleep //sleep in atomic context

Fix by removing msleep() and replacing with mdelay().

Subject: [PATCH 0433/1480] staging: ks7010: Avoid clashing function prototypes

When built with Control Flow Integrity, function prototypes between
caller and function declaration must match. These mismatches are visible
at compile time with the new -Wcast-function-type-strict in Clang[1].

Fix a total of 27 warnings like these:

drivers/staging/ks7010/ks_wlan_net.c:2415:2: warning: cast from 'int (*)(struct net_device *, struct iw_request_info *, struct iw_point *, char *)' to 'iw_handler' (aka 'int (*)(struct net_device *, struct iw_request_info *, union iwreq_data *, char *)') converts to incompatible function type [-Wcast-function-type-strict]
        (iw_handler)ks_wlan_get_firmware_version,/* 3 KS_WLAN_GET_FIRM_VERSION */
        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The ks_wlan_net Wireless Extension handler callbacks (iw_handler) use a
union for the data argument. Actually use the union and perform explicit
member selection in the function body instead of having a function
prototype mismatch. There are no resulting binary differences
before/after changes.

These changes were made partly manually and partly with the help of
Coccinelle.

Subject: [PATCH 0435/1480] staging: rtl8192u: remove redundant macro
 definitions

Several ieee80211_* symbol names are extended with _rsl tag using
macros. This is done to avoid a conflict when a similar symbol is
already in use in another part of kernel and may lead to conflicts.
However, most of these base symbol names are not found to being used
anywhere in the code and hence are not useful today. These symbols
are not used outside of the module and hence can be safely removed.
The code continues to use the original symbol names.

Subject: [PATCH 0436/1480] class: fix possible memory leak in
 __class_register()

If class_add_groups() returns error, the 'cp->subsys' need be
unregister, and the 'cp' need be freed.

We can not call kset_unregister() here, because the 'cls' will
be freed in callback function class_release() and it's also
freed in caller's error path, it will cause double free.

So fix this by calling kobject_del() and kfree_const(name) to
cleanup kobject. Besides, call kfree() to free the 'cp'.

Fault injection test can trigger this:

Subject: [PATCH 0441/1480] sysfs: update Documentation

Make editing corrections and updates to sysfs.rst:

- spell "sysfs" consistently (vs. "Sysfs")
- align field names in a struct
- fix some punctuation and grammar
- list more /sys top-level subdirectories
- change 'fuse.txt' to 'fuse.rst' (although I don't see where the
  example is)

Subject: [PATCH 0442/1480] driver core: class: make namespace and
 get_ownership take const *

The callbacks in struct class namespace() and get_ownership() do not
modify the struct device passed to them, so mark the pointer as constant
and fix up all callbacks in the kernel to have the correct function
signature.

This helps make it more obvious what calls and callbacks do, and do not,
modify structures passed to them.

Subject: [PATCH 0449/1480] vfio/iova_bitmap: Explicitly include linux/slab.h

kzalloc/kzfree are used so include `slab.h`. While it happens to work
without it, due to commit 8b9f3ac5b01d ("fs: introduce alloc_inode_sb() to
allocate filesystems specific inode") which indirectly includes via:

. ./include/linux/mm.h
.. ./include/linux/huge_mm.h
... ./include/linux/fs.h
.... ./include/linux/slab.h

Make it explicit should any of its indirect dependencies be dropped/changed
for entirely different reasons as it was the cause prior to commit above
recently (i.e. <= v5.18).

Subject: [PATCH 0450/1480] vfio/iova_bitmap: Fix PAGE_SIZE unaligned bitmaps

iova_bitmap_set() doesn't consider the end of the page boundary when the
first bitmap page offset isn't zero, and wrongly changes the consecutive
page right after. Consequently this leads to missing dirty pages from
reported by the device as seen from the VMM.

The current logic iterates over a given number of base pages and clamps it
to the remaining indexes to iterate in the last page.  Instead of having to
consider extra pages to pin (e.g. first and extra pages), just handle the
first page as its own range and let the rest of the bitmap be handled as if
it was base page aligned.

This is done by changing iova_bitmap_mapped_remaining() to return PAGE_SIZE
- pgoff (on the first bitmap page), and leads to pgoff being set to 0 on
following iterations.

Subject: [PATCH 0455/1480] cacheinfo: Decrement refcount in
 cache_setup_of_node()

Refcounts to DT nodes are only incremented in the function
and never decremented. Decrease the refcounts when necessary.

Subject: [PATCH 0456/1480] driver core: Use kstrtobool() instead of
 strtobool()

strtobool() is the same as kstrtobool().
However, the latter is more used within the kernel.

In order to remove strtobool() and slightly simplify kstrtox.h, switch to
the other function name.

While at it, include the corresponding header file (<linux/kstrtox.h>)

Subject: [PATCH 0457/1480] driver core: Fix bus_type.match() error handling in
 __driver_attach()

When a driver registers with a bus, it will attempt to match with every
device on the bus through the __driver_attach() function. Currently, if
the bus_type.match() function encounters an error that is not
-EPROBE_DEFER, __driver_attach() will return a negative error code, which
causes the driver registration logic to stop trying to match with the
remaining devices on the bus.

This behavior is not correct; a failure while matching a driver to a
device does not mean that the driver won't be able to match and bind
with other devices on the bus. Update the logic in __driver_attach()
to reflect this.

Fixes: 656b8035b0ee ("ARM: 8524/1: driver cohandle -EPROBE_DEFER from bus_type.match()")

Subject: [PATCH 0458/1480] virt: fsl_hypervisor: Replace NO_IRQ by 0

NO_IRQ is used to check the return of irq_of_parse_and_map().

On some architecture NO_IRQ is 0, on other architectures it is -1.

irq_of_parse_and_map() returns 0 on error, independent of NO_IRQ.

So use 0 instead of using NO_IRQ.

Subject: [PATCH 0461/1480] chardev: Fix potential memory leak when cdev_add()
 failed

Some init function of cdev(like comedi) will call kobject_set_name()
before cdev_add(), but won't free the cdev.kobj.name or put the ref cnt
of cdev.kobj when cdev_add() failed. As the result, cdev.kobj.name will
be leaked.

Free the name of kobject in cdev_add() fail path to prevent memleak. With
this fix, the callers don't need to care about freeing the name of
kobject if cdev_add() fails.

Subject: [PATCH 0463/1480] uio: uio_fsl_elbc_gpcm: Replace NO_IRQ by 0

NO_IRQ is used to check the return of irq_of_parse_and_map().

On some architecture NO_IRQ is 0, on other architectures it is -1.

irq_of_parse_and_map() returns 0 on error, independent of NO_IRQ.

So use 0 instead of using NO_IRQ.

Subject: [PATCH 0465/1480] firmware: google: Implement cbmem in sysfs driver

The CBMEM area is a downward-growing memory region used by coreboot to
dynamically allocate tagged data structures ("CBMEM entries") that
remain resident during boot.

This implements a driver which exports access to the CBMEM entries
via sysfs under /sys/bus/coreboot/devices/cbmem-<id>.

This implementation is quite versatile.  Examples of how it could be
used are given below:

* Tools like util/cbmem from the coreboot tree could use this driver
  instead of finding CBMEM in /dev/mem directly.  Alternatively,
  firmware developers debugging an issue may find the sysfs interface
  more ergonomic than the cbmem tool and choose to use it directly.

* The crossystem tool, which exposes verified boot variables, can use
  this driver to read the vboot work buffer.

* Tools which read the BIOS SPI flash (e.g., flashrom) can find the
  flash layout in CBMEM directly, which is significantly faster than
  searching the flash directly.

Write access is provided to all CBMEM regions via
/sys/bus/coreboot/devices/cbmem-<id>/mem, as the existing cbmem
tooling updates this memory region, and envisioned use cases with
crossystem can benefit from updating memory regions.

 configuration

Commit b74351287d4b ("uio: fix a sleep-in-atomic-context bug in
uio_dmem_genirq_irqcontrol()") started calling disable_irq() without
holding the spinlock because it can sleep. However, that fix introduced
another bug: if interrupt is already disabled and a new disable request
comes in, then the spinlock is not unlocked:

('myfpga' is a simple 'uio_dmem_genirq' driver I wrote to test this)

The implementation of "uio_dmem_genirq" was based on "uio_pdrv_genirq" and
it is used in a similar manner to the "uio_pdrv_genirq" driver with respect
to interrupt configuration and handling. At the time "uio_dmem_genirq" was
introduced, both had the same implementation of the 'uio_info' handlers
irqcontrol() and handler(). Then commit 34cb27528398 ("UIO: Fix concurrency
issue"), which was only applied to "uio_pdrv_genirq", ended up making them
a little different. That commit, among other things, changed disable_irq()
to disable_irq_nosync() in the implementation of irqcontrol(). The
motivation there was to avoid a deadlock between irqcontrol() and
handler(), since it added a spinlock in the irq handler, and disable_irq()
waits for the completion of the irq handler.

By changing disable_irq() to disable_irq_nosync() in irqcontrol(), we also
avoid the sleeping-while-atomic bug that commit b74351287d4b ("uio: fix a
sleep-in-atomic-context bug in uio_dmem_genirq_irqcontrol()") was trying to
fix. Thus, this fixes the missing unlock in irqcontrol() by importing the
implementation of irqcontrol() handler from the "uio_pdrv_genirq" driver.
In the end, it reverts commit b74351287d4b ("uio: fix a
sleep-in-atomic-context bug in uio_dmem_genirq_irqcontrol()") and change
disable_irq() to disable_irq_nosync().

It is worth noting that this still does not address the concurrency issue
fixed by commit 34cb27528398 ("UIO: Fix concurrency issue"). It will be
addressed separately in the next commits.

Split out from commit 34cb27528398 ("UIO: Fix concurrency issue").

Subject: [PATCH 0467/1480] uio: uio_dmem_genirq: Fix deadlock between irq
 config and handling

This fixes a concurrency issue addressed in commit 34cb27528398 ("UIO: Fix
concurrency issue"):

  "In a SMP case there was a race condition issue between
  Uio_pdrv_genirq_irqcontrol() running on one CPU and irq handler on
  another CPU. Fix it by spin_locking shared resources access inside irq
  handler."

The implementation of "uio_dmem_genirq" was based on "uio_pdrv_genirq" and
it is used in a similar manner to the "uio_pdrv_genirq" driver with respect
to interrupt configuration and handling. At the time "uio_dmem_genirq" was
merged, both had the same implementation of the 'uio_info' handlers
irqcontrol() and handler(), thus, both had the same concurrency issue
mentioned by the above commit. However, the above patch was only applied to
the "uio_pdrv_genirq" driver.

Split out from commit 34cb27528398 ("UIO: Fix concurrency issue").

Subject: [PATCH 0468/1480] uio: uio_dmem_genirq: Use non-atomic bit operations
 in irq config and handling

This finishes the port of the irq configuration and handling from
"uio_pdrv_genirq" to "uio_dmem_genirq". It changes the atomic
bit-manipulation routines to their non-atomic counterparts as we are
already guarding the code by spinlock.

Split out from commit 34cb27528398 ("UIO: Fix concurrency issue").

 of_irq_get_byname to get irq

Not only platform devices described by OF have named interrupts, but
devices described by ACPI also have named interrupts. The fwnode is an
abstraction to different standards, and using fwnode_irq_get_byname can
support more devices.

Replace printk(KERN_WARNING) by pr_warn() and printk() by pr_info().

While at it, use %pa for the resource_size_t variables. With that,
for the sake of consistency, introduce a temporary variable for
the end address in iomem_map_sanity_check() like it's done in another
function in the same module.

Currently DEFINE_RES_NAMED() can only be used to fill the static data.
In some cases it would be convenient to use it as right value in the
assignment operation. But it can't be done as is, because compiler has
no clue about the data layout. Converting it to be a compound literal
allows the above mentioned usage.

Simple Power-Managed bus controller may need functional clock(s)
to be enabled before child devices connected to the bus can be
accessed.  Get the clock(s) as a bulk and enable/disable the
clock(s) when the bus is being power managed.

One example is that Freescale i.MX8qxp pixel link MSI bus controller
needs MSI clock and AHB clock to be enabled before accessing child
devices.

+description: |
+  i.MX8qxp pixel link MSI bus is used to control settings of PHYs, I/Os
+  sitting together with the PHYs.  It is not the same as the MSI bus coming
+  from i.MX8 System Controller Unit (SCU) which is used to control power,
+  clock and reset through the i.MX8 Distributed Slave System Controller (DSC).
+
+  i.MX8qxp pixel link MSI bus is a simple memory-mapped bus. Two input clocks,
+  that is, MSI clock and AHB clock, need to be enabled so that peripherals
+  connected to the bus can be accessed. Also, the bus is part of a power
+  domain. The power domain needs to be enabled before the peripherals can
+  be accessed.
+
+  Peripherals in i.MX8qm/qxp imaging, LVDS, MIPI DSI and HDMI TX subsystems,
+  like I2C controller, PWM controller, MIPI DSI controller and Control and
+  Status Registers (CSR) module, are accessed through the bus.
+
+  The i.MX System Controller Firmware (SCFW) owns and uses the i.MX8qm/qxp
+  pixel link MSI bus controller and does not allow SCFW user to control it.
+  So, the controller's registers cannot be accessed by SCFW user. Hence,
+  the interrupts generated by the controller don't make any sense from SCFW
+  user's point of view.

Subject: [PATCH 0476/1480] greybus: svc: Use kstrtobool() instead of
 strtobool()

strtobool() is the same as kstrtobool().
However, the latter is more used within the kernel.

In order to remove strtobool() and slightly simplify kstrtox.h, switch to
the other function name.

While at it, include the corresponding header file (<linux/kstrtox.h>)

Certain files in procfs are formatted in byteorder-dependent formats.
For example the IP addresses in /proc/net/udp.

When using emulation like qemu-user, applications are not guaranteed to
be using the same byteorder as the kernel.
Therefore the kernel needs to provide a way for applications to discover
the byteorder used in API-filesystems.
Using systemcalls is not enough because these are intercepted and
translated by the emulation.

Also this makes it easier for non-compiled applications like
shellscripts to discover the byteorder.

Subject: [PATCH 0478/1480] vmlinux.lds.h: add BOUNDED_SECTION* macros

vmlinux.lds.h has ~45 occurrences of this general pattern:

  __start_foo = .;
  KEEP(*(foo))
  __stop_foo = .;

Reduce this pattern to a (group of 4) macros, and use them to reduce
linecount.  This was inspired by the codetag patchset.

no functional change.

Subject: [PATCH 0479/1480] vmlinux.lds.h: place optional header space in
 BOUNDED_SECTION

Extend recently added BOUNDED_SECTION(_name) macro by adding a
KEEP(*(.gnu.linkonce.##_name)) before the KEEP(*(_name)).

This does nothing by itself, vmlinux is the same before and after this
patch.  But if a developer adds a .gnu.linkonce.foo record, that
record is placed in the front of the section, where it can be used as
a header for the table.

The intent is to create an up-link to another organizing struct, from
where related tables can be referenced.  And since every item in a
table has a known offset from its header, that same offset can be used
to fetch records from the related tables.

By itself, this doesnt gain much, unless maybe the pattern of access
is to scan 1 or 2 fields in each fat record, but with 2 16 bit .map*
fields added, we could de-duplicate 2 related tables.

The use case here is struct _ddebug, which has 3 pointers (function,
file, module) with substantial repetition; respectively 53%, 90%, and
the module column is fully recoverable after dynamic_debug_init()
splits the table into a linked list of "module" chunks.

On a DYNAMIC_DEBUG=y kernel with 5k pr_debugs, the memory savings
should be ~100 KiB.

Subject: [PATCH 0480/1480] vfio/ccw: create a parent struct

Move the stuff associated with the mdev parent (and thus the
subchannel struct) into its own struct, and leave the rest in
the existing private structure.

The subchannel will point to the parent, and the parent will point
to the private, for the areas where one or both are needed. Further
separation of these structs will follow.

Subject: [PATCH 0481/1480] vfio/ccw: remove private->sch

These places all rely on the ability to jump from a private
struct back to the subchannel struct. Rather than keeping a
copy in our back pocket, let's use the relationship provided
by the vfio_device embedded within the private.

Subject: [PATCH 0482/1480] vfio/ccw: move private initialization to callback

There's already a device initialization callback that is used to
initialize the release completion workaround that was introduced
by commit ebb72b765fb49 ("vfio/ccw: Use the new device life cycle
helpers").

Move the other elements of the vfio_ccw_private struct that
require distinct initialization over to that routine.

With that done, the vfio_ccw_alloc_private routine only does a
kzalloc, so fold it inline.

Subject: [PATCH 0483/1480] vfio/ccw: move private to mdev lifecycle

Now that the mdev parent data is split out into its own struct,
it is safe to move the remaining private data to follow the
mdev probe/remove lifecycle. The mdev parent data will remain
where it is, and follow the subchannel and the css driver
interfaces.

Subject: [PATCH 0486/1480] vfio/ccw: replace vfio_init_device with _alloc_

Now that we have a reasonable separation of structs that follow
the subchannel and mdev lifecycles, there's no reason we can't
call the official vfio_alloc_device routine for our private data,
and behave like everyone else.

Subject: [PATCH 0487/1480] vfio: Remove vfio_free_device

With the "mess" sorted out, we should be able to inline the
vfio_free_device call introduced by commit cb9ff3f3b84c
("vfio: Add helpers for unifying vfio_device life cycle")
and remove them from driver release callbacks.

Subject: [PATCH 0488/1480] perf lock: Allow concurrent record and report

To support live monitoring of kernel lock contention without BPF,
it should support something like below:

  # perf lock record -a -o- sleep 1 | perf lock contention -i-
   contended   total wait     max wait     avg wait         type   caller

           2     10.27 us      6.17 us      5.13 us     spinlock   load_balance+0xc03
           1      5.29 us      5.29 us      5.29 us     rwlock:W   ep_scan_ready_list+0x54
           1      4.12 us      4.12 us      4.12 us     spinlock   smpboot_thread_fn+0x116
           1      3.28 us      3.28 us      3.28 us        mutex   pipe_read+0x50

To do that, it needs to handle HEAD_ATTR, HEADER_EVENT_UPDATE and
HEADER_TRACING_DATA which are generated only for the pipe mode.
And setting event handler also should be delayed until it gets the
event information.

Rename the neoverse-n2 folder to make it clear that it includes V2, and
add V2 to mapfile.csv. V2 has the same events as N2, visible by running
the following command in the ARM-software/data github repo [1]:

  diff pmu/neoverse-v2.json pmu/neoverse-n2.json | grep code

Testing:

  $ perf test pmu

Subject: [PATCH 0492/1480] usb: fotg2: add Gemini-specific handling

The Cortina Systems Gemini has bolted on a PHY inside the
silicon that can be handled by six bits in a MISC register in
the system controller.

If we are running on Gemini, look up a syscon regmap through
a phandle and enable VBUS and optionally the Mini-B connector.

If the device is flagged as "wakeup-source" using the standard
DT bindings, we also enable this in the global controller for
respective port.

Subject: [PATCH 0493/1480] usb: fotg210-udc: Fix ages old endianness issues

The code in the FOTG210 driver isn't entirely endianness-agnostic
as reported by the kernel robot sparse testing. This came to
the surface while moving the files around.

The driver is only used on little-endian systems, so this causes
no real-world regression, but it is nice to be strict and have
some compile coverage also on big endian machines, so fix it
up with the right LE accessors.

Subject: [PATCH 0494/1480] usb: Check !irq instead of irq == NO_IRQ

NO_IRQ is a relic from the old days. It is not used anymore in core
functions. By the way, function irq_of_parse_and_map() returns value 0
on error.

In some drivers, NO_IRQ is erroneously used to check the return of
irq_of_parse_and_map().

It is not a real bug today because the only architectures using the
drivers being fixed by this patch define NO_IRQ as 0, but there are
architectures which define NO_IRQ as -1. If one day those
architectures start using the non fixed drivers, there will be a
problem.

Long time ago Linus advocated for not using NO_IRQ, see
https://lkml.org/lkml/2005/11/21/221 . He re-iterated the same view
recently in https://lkml.org/lkml/2022/10/12/622

So test !irq instead of tesing irq == NO_IRQ.

Subject: [PATCH 0496/1480] char: xillybus: Prevent use-after-free due to race
 condition

The driver for XillyUSB devices maintains a kref reference count on each
xillyusb_dev structure, which represents a physical device. This reference
count reaches zero when the device has been disconnected and there are no
open file descriptors that are related to the device. When this occurs,
kref_put() calls cleanup_dev(), which clears up the device's data,
including the structure itself.

However, when xillyusb_open() is called, this reference count becomes
tricky: This function needs to obtain the xillyusb_dev structure that
relates to the inode's major and minor (as there can be several such).
xillybus_find_inode() (which is defined in xillybus_class.c) is called
for this purpose. xillybus_find_inode() holds a mutex that is global in
xillybus_class.c to protect the list of devices, and releases this
mutex before returning. As a result, nothing protects the xillyusb_dev's
reference counter from being decremented to zero before xillyusb_open()
increments it on its own behalf. Hence the structure can be freed
due to a rare race condition.

To solve this, a mutex is added. It is locked by xillyusb_open() before
the call to xillybus_find_inode() and is released only after the kref
counter has been incremented on behalf of the newly opened inode. This
protects the kref reference counters of all xillyusb_dev structs from
being decremented by xillyusb_disconnect() during this time segment, as
the call to kref_put() in this function is done with the same lock held.

There is no need to hold the lock on other calls to kref_put(), because
if xillybus_find_inode() finds a struct, xillyusb_disconnect() has not
made the call to remove it, and hence not made its call to kref_put(),
which takes place afterwards. Hence preventing xillyusb_disconnect's
call to kref_put() is enough to ensure that the reference doesn't reach
zero before it's incremented by xillyusb_open().

It would have been more natural to increment the reference count in
xillybus_find_inode() of course, however this function is also called by
Xillybus' driver for PCIe / OF, which registers a completely different
structure. Therefore, xillybus_find_inode() treats these structures as
void pointers, and accordingly can't make any changes.

Subject: [PATCH 0497/1480] i2c: designware: Fix slave state machine for
 sequential reads

Some read types from I2C bus don't work correctly when testing the
i2c-designware-slave.c with the slave-eeprom backend. The same reads
work correctly when testing with a real 24c02 EEPROM chip.

In the following tests an i2c-designware-slave.c instance with the
slave-eeprom backend is configured to act as a simulated 24c02 at
address 0x65 on an I2C host bus 6:

1. i2cdump -y 6 0x65 b (OK)
   Random read. Each byte are read using a byte address write with a
   current address read in a same message.
2. i2cdump -y 6 0x65 c (OK, was NOK before commit 3b5f7f10ff6e when it
                        was repeating the 1st byte)
   Repeated current address read. One byte address write message
   followed by repeated current address read messages.
3. i2cdump -y 6 0x65 i (NOK, each 32 byte block repeats the 1st byte of
                        block)
   Sequential read using SMBus Block Read. For each 32 byte block a byte
   address write followed by 32 sequental reads in a same message.

These findings are explained because the implementation has had a
mismatch between hardware interrupts and what I2C slave events should be
sent after those interrupts. Despite that the case 1 happened to have
always the I2C slave events sent to a right order with a right data
between backend and the I2C bus.

Hardware generates the DW_IC_INTR_RD_REQ interrupt when another host is
attempting to read and for sequential reads after. DW_IC_INTR_RX_DONE
occurs when host does not acknowledge a transmitted byte which is an
indication the end of transmission.

Those interrupts do not match directly with I2C_SLAVE_READ_REQUESTED and
I2C_SLAVE_READ_PROCESSED events which is how the code was and is
practically using them. The slave-eeprom backend increases the buffer
index with the I2C_SLAVE_READ_PROCESSED event and returns the data from
current index when receiving only the I2C_SLAVE_READ_REQUESTED event.

That explains the repeated bytes in case 3 and also case 2 before
commit 3b5f7f10ff6e ("i2c: designware: slave should do WRITE_REQUESTED
before WRITE_RECEIVED").

Patch fixes the case 3 while keep cases 1 and 2 working with following
changes:

- First DW_IC_INTR_RD_REQ interrupt will change the state machine to
  read in progress state, send I2C_SLAVE_READ_REQUESTED event and
  transmit the first byte from backend
- Subsequent DW_IC_INTR_RD_REQ interrupts will send
  I2C_SLAVE_READ_PROCESSED events and transmit next bytes from backend
- STOP won't change the state machine. Otherwise case 2 won't work since
  we cannot distinguish current address read from sequentiel read
- DW_IC_INTR_RX_DONE interrupt is needless since there is no mechanism
  to inform it to a backend. It cannot be used to change state machine
  at the end of read either due the same reason than above
- Next host write to us will change the state machine from read to write
  in progress state
- STATUS_WRITE_IN_PROGRESS and STATUS_READ_IN_PROGRESS are considered
  now to be status flags not the state of the driver. This is how we
  treat them in i2c-designware-master.c

While at it do not test the return code from i2c_slave_event() for
I2C_SLAVE_READ_REQUESTED and I2C_SLAVE_READ_PROCESSED since it returns
always 0.

Subject: [PATCH 0498/1480] i2c: designware: Empty receive FIFO in slave
 interrupt handler

Writes from I2C bus often fail when testing the i2c-designware-slave.c
with the slave-eeprom backend. The same writes work correctly when
testing with a real 24c02 EEPROM chip.

In the tests below an i2c-designware-slave.c instance with the
slave-eeprom backend is configured to act as a simulated 24c02 at
address 0x65 on an I2C host bus 6.

1. i2cset -y 6 0x65 0x00 0x55

Single byte 0x55 write into address 0x00. No data goes into simulated
EEPROM. Debug prints from the i2c_dw_irq_handler_slave():

0x1 STATUS SLAVE_ACTIVITY=0x0 : RAW_INTR_STAT=0x714 : INTR_STAT=0x204
0x1 STATUS SLAVE_ACTIVITY=0x0 : RAW_INTR_STAT=0x514 : INTR_STAT=0x4

2. i2ctransfer -y 6 w9@0x65 0x00 0xff-

Write 8 bytes with decrementing value starting from 0xff at address 0x00
and forward. Only some of the data goes into arbitrary addresses.
Content is something like below but varies:

00000000  f9 f8 00 00 00 00 00 00  00 00 00 00 00 00 00 00  |................|
00000050  00 00 00 00 00 00 ff fe  00 00 00 00 00 00 00 00  |................|
000000f0  00 00 00 00 00 00 00 00  00 00 00 00 00 fc fb fa  |................|

In this case debug prints were:

0x1 STATUS SLAVE_ACTIVITY=0x1 : RAW_INTR_STAT=0x514 : INTR_STAT=0x4
0x1 STATUS SLAVE_ACTIVITY=0x1 : RAW_INTR_STAT=0x514 : INTR_STAT=0x4
0x1 STATUS SLAVE_ACTIVITY=0x0 : RAW_INTR_STAT=0x714 : INTR_STAT=0x204
0x1 STATUS SLAVE_ACTIVITY=0x0 : RAW_INTR_STAT=0x514 : INTR_STAT=0x4
0x1 STATUS SLAVE_ACTIVITY=0x0 : RAW_INTR_STAT=0x514 : INTR_STAT=0x4
0x1 STATUS SLAVE_ACTIVITY=0x0 : RAW_INTR_STAT=0x514 : INTR_STAT=0x4
0x1 STATUS SLAVE_ACTIVITY=0x0 : RAW_INTR_STAT=0x514 : INTR_STAT=0x4
0x1 STATUS SLAVE_ACTIVITY=0x0 : RAW_INTR_STAT=0x514 : INTR_STAT=0x4
0x1 STATUS SLAVE_ACTIVITY=0x0 : RAW_INTR_STAT=0x514 : INTR_STAT=0x4
0x1 STATUS SLAVE_ACTIVITY=0x0 : RAW_INTR_STAT=0x510 : INTR_STAT=0x0

Both cases show there is more data coming from the receive FIFO still
after detecting the STOP condition. This can be seen from interrupt
status bits DW_IC_INTR_STOP_DET (0x200) and DW_IC_INTR_RX_FULL (0x4).

Perhaps due interrupt latencies the receive FIFO is not read fast
enough, STOP detection happens synchronously when it occurs on the I2C
bus and the DW_IC_INTR_RX_FULL keeps coming as long as there are more
bytes in the receive FIFO.

Fix this by reading the receive FIFO completely empty whenever
DW_IC_INTR_RX_FULL occurs. Use RFNE, Receive FIFO Not Empty bit in the
DW_IC_STATUS register to loop through bytes in the FIFO.

While at it do not test the return code from i2c_slave_event() for the
I2C_SLAVE_WRITE_RECEIVED since to my understanding this hardware cannot
generate NACK to incoming bytes and debug print itself does not have
much value.

Subject: [PATCH 0503/1480] i2c: designware: Do not process interrupt when
 device is suspended

Do not return with interrupt handled if host controller is off and thus
interrupt is originating from other device or is spurious.

Add a check to detect when controller is runtime suspended or
transitioning/reset. In latter case all raw interrupt status register
bits may read one. In both cases return IRQ_NONE to indicate interrupt
was not from this device.

Subject: [PATCH 0504/1480] i2c: designware: Move debug print in i2c_dw_isr()

It is kind of needless to print interrupt status when code immediately
after that finds interrupt was not originating from this device.
Therefore move it after spurious interrupt detection.

Subject: [PATCH 0505/1480] i2c: designware: Simplify master interrupt handler

In my opinion a few lines of spurious interrupt detection code can be
moved to the actual master interrupt handling function i2c_dw_isr()
without hurting readability.

Subject: [PATCH 0506/1480] i2c: designware: Remove common i2c_dw_disable_int()

Commit 90312351fd1e ("i2c: designware: MASTER mode as separated driver")
introduced disable_int pointer but there is no real use for it. Both
i2c-designware-master.c and i2c-designware-slave.c set it to the same
i2c_dw_disable_int() and scope is inside the same kernel module.

Since i2c_dw_disable_int() is just masking interrupts and the direct
DW_IC_INTR_MASK register write looks more clear in the code use that and
remove it from common code.

Subject: [PATCH 0508/1480] i2c: designware: Add comment to custom register
 value constants

DW_IC_COMP_VERSION register contains the ASCII representation of the
Synopsys component version. Here 0x3131312A == "111*" means version
1.11* required for DW_IC_SDA_HOLD register availability where '*' means
any letter starting from 'a'.

DW_IC_COMP_TYPE is constant and is derived from two ASCII letters "DW"
followed by a 16-bit unsigned number.

Subject: [PATCH 0510/1480] i2c: /pasemi: PASemi I2C controller IRQ enablement

This patch adds IRQ support to the PASemi I2C controller driver to
increase the performace of I2C transactions on platforms with PASemi I2C
controllers. While primarily intended for Apple silicon platforms, this
patch should also help in enabling IRQ support for older PASemi hardware
as well should the need arise.

This version of the patch has been tested on an M1 Ultra Mac Studio,
as well as an M1 MacBook Pro, and userspace launches successfully
while using the IRQ path for I2C transactions.

Subject: [PATCH 0513/1480] interconnect: qcom: osm-l3: Use
 platform-independent node ids

The identifiers used for nodes needs to be unique in the running system,
but defining them per platform results in a lot of duplicated
definitions and prevents us from using generic compatibles.

As these identifiers are not exposed outside the kernel, change to use
driver-local numbers, picked completely at random.

Subject: [PATCH 0515/1480] interconnect: qcom: osm-l3: Add per-core EPSS L3
 support

The EPSS instance in e.g. SM8350 and SC8280XP has per-core L3 voting
enabled. In this configuration, the "shared" vote is done using the
REG_L3_VOTE register instead of PERF_STATE.

Rename epss_l3 to clarify that it's affecting the PERF_STATE register
and add a new L3_VOTE description. Given platform lineage it's assumed
that the L3_VOTE-based case will be the predominant one, so use this for
a new generic qcom,epss-l3 compatible.

While adding the EPSS generic, also add qcom,osm-l3.

Subject: [PATCH 0516/1480] interconnect: qcom: osm-l3: Simplify osm_l3_set()

The aggregation over votes for all nodes in the provider will always
only find the bandwidth votes for the destination side of the path.
Further more, the average kBps value will always be 0.

Simplify the logic by directly looking at the destination node's peak
bandwidth request.

Subject: [PATCH 0520/1480] perf stat: Fix --metric-only --json output

Currently it prints all metric headers for JSON output.  But actually it
skips some metrics with valid_only_metric().  So the output looks like:

  $ perf stat --metric-only --json true
  {"unit" : "CPUs utilized", "unit" : "/sec", "unit" : "/sec", "unit" : "/sec", "unit" : "GHz", "unit" : "insn per cycle", "unit" : "/sec", "unit" : "branch-misses of all branches"}
  {"metric-value" : "3.861"}{"metric-value" : "0.79"}{"metric-value" : "3.04"}

As you can see there are 8 units in the header but only 3 metric-values
are there.  It should skip the unused headers as well.  Also each unit
should be printed as a separate object like metric values.

With this patch:

  $ perf stat --metric-only --json true
  {"unit" : "GHz"}{"unit" : "insn per cycle"}{"unit" : "branch-misses of all branches"}
  {"metric-value" : "4.166"}{"metric-value" : "0.73"}{"metric-value" : "2.96"}

The num_print_interval and config->interval_clear should be checked

the --interval-clear option could print the headers for the CSV or

The pm variable holds an appropriate function to print metrics for CSV
anf JSON already.  So we can combine the if statement to simplify the
code a little bit.  This also matches to the above condition for non-CSV
and non-JSON case.

From 4e016f969529f2aec0545e90119e7eb3cb124c46 Mon Sep 17 00:00:00 2001
From: Yishai Hadas <yishaih@nvidia.com>
Date: Sun, 6 Nov 2022 19:46:18 +0200
Subject: [PATCH 0525/1480] vfio: Add an option to get migration data size

Add an option to get migration data size by introducing a new migration
feature named VFIO_DEVICE_FEATURE_MIG_DATA_SIZE.

Upon VFIO_DEVICE_FEATURE_GET the estimated data length that will be
required to complete STOP_COPY is returned.

This option may better enable user space to consider before moving to
STOP_COPY whether it can meet the downtime SLA based on the returned
data.

The patch also includes the implementation for mlx5 and hisi for this
new option to make it feature complete for the existing drivers in this
area.

Fix a typo in mlx5vf_cmd_load_vhca_state() to use the 'load' memory
layout.

As in/out sizes are equal for save and load commands there wasn't any
functional issue.

Subject: [PATCH 0532/1480] perf tracepoint: Sort events in iterator

In print_tracepoint_events() use tracing_events__scandir_alphasort() and
scandir alphasort so that the subsystem and events are sorted and don't
need a secondary qsort. Locally this results in the following change:

...
   ext4:ext4_zero_range                               [Tracepoint event]
-  fib6:fib6_table_lookup                             [Tracepoint event]
   fib:fib_table_lookup                               [Tracepoint event]
+  fib6:fib6_table_lookup                             [Tracepoint event]
   filelock:break_lease_block                         [Tracepoint event]
...

ie fib6 now is after fib and not before it. This is more consistent
with how numbers are more generally sorted, such as:

...
  syscalls:sys_enter_renameat                        [Tracepoint event]
  syscalls:sys_enter_renameat2                       [Tracepoint event]
...

and so an improvement over the qsort approach.

with arbitrary PMUs, for example:

```
$ perf list --unit msr pmu

List of pre-defined events (to be used in -e or -M):

Subject: [PATCH 0534/1480] perf list: Simplify cache event printing

The current code computes an array of cache names then sorts and prints
them. Use a strlist to create a list of names that is sorted. Keep the
hybrid names, it is unclear how to generalize it, but drop the
computation of evt_pmus that is never used.

Subject: [PATCH 0536/1480] perf pmu: Restructure print_pmu_events() to avoid
 memory allocations

Previously print_pmu_events() would compute the values to be printed,
place them in struct sevent, sort them and then print them.

Modify the code so that struct sevent holds just the PMU and event, sort
these and then in the main print loop calculate aliases for names, etc.

This avoids memory allocations for copied values as they are computed
then printed.

Subject: [PATCH 0537/1480] perf stat: Clear screen only if output file is a
 tty

The --interval-clear option makes perf stat to clear the terminal at
each interval.  But it doesn't need to clear the screen when it saves
to a file.  Make it fail when it's enabled with the output options.

  $ perf stat -I 1 --interval-clear -o myfile true
  --interval-clear does not work with output

   Usage: perf stat [<options>] [<command>]

      -o, --output <file>   output file name
          --log-fd <n>      log output to fd, instead of stderr
          --interval-clear  clear screen in between new interval

Subject: [PATCH 0539/1480] perf stat: Split print_noise_pct() function

Likewise, split print_noise_pct() for each output mode.  Although it's
a tiny function, more logic will be added soon so it'd be better split
it and treat it in the same way.

And split it for each output mode like others.  I believe it makes the
code simpler and more intuitive.  Now abs_printout() becomes just to
call sub-functions.

Date: Mon, 14 Nov 2022 15:02:15 -0800
Subject: [PATCH 0543/1480] perf stat: Handle bad events in abs_printout()

In the printout() function, it checks if the event is bad (i.e. not
counted or not supported) and print the result.  But it does the same
what abs_printout() is doing.  So add an argument to indicate the value
is ok or not and use the same function in both cases.

Subject: [PATCH 0544/1480] perf stat: Add before_metric argument

Unfortunately, event running time, percentage and noise data are printed
in different positions in normal output than CSV/JSON.  I think it's
better to put such details in where it actually prints.

So add before_metric argument to print_noise() and print_running() and
call them twice before and after the metric.

Subject: [PATCH 0549/1480] perf stat: Remove impossible condition

The print would run only if metric_only is not set, but it's already in a
block that says it's in metric_only case.  And there's no place to change
the setting.

Subject: [PATCH 0550/1480] perf stat: Rework header display

There are print_header() and print_interval() to print header lines before
actual counter values.  Also print_metric_headers() needs to be called for
the metric-only case.

Let's move all these logics to a single place including num_print_iv to
refresh the headers for interval mode.

Subject: [PATCH 0552/1480] perf stat: Factor out prefix display

The prefix is needed for interval mode to print timestamp at the
beginning of each line.  But the it's tricky for the metric only
mode since it doesn't print every evsel and combines the metrics
into a single line.

So it needed to pass 'first' argument to print_counter_aggrdata()
to determine if the current event is being printed at first.  This
makes the code hard to read.

Let's move the logic out of the function and do it in the outer
print loop.  This would enable further cleanups later.

Subject: [PATCH 0554/1480] perf stat: Support --for-each-cgroup and

When we have events for each cgroup, the metric should be printed for
each cgroup separately.  Add print_cgroup_counter() to handle that
situation properly.

Also change print_metric_headers() not to print duplicate headers
by checking cgroups.

  $ perf stat -a --for-each-cgroup system.slice,user.slice --metric-only sleep 1

Subject: [PATCH 0555/1480] perf stat: Add print_aggr_cgroup() for
 --for-each-cgroup and --topdown

Normally, --for-each-cgroup only works with AGGR_GLOBAL.  However
the --topdown on some cpu (e.g. Intel Skylake) converts it to the
AGGR_CORE internally.

To support those machines, add print_aggr_cgroup and handle the events
like in print_cgroup_events().

  $ perf stat -a --for-each-cgroup system.slice,user.slice --topdown sleep 1
  nmi_watchdog enabled with topdown. May give wrong results.
  Disable with echo 0 > /proc/sys/kernel/nmi_watchdog

Subject: [PATCH 0558/1480] perf build: Install libsubcmd locally when building

The perf build currently has a '-Itools/lib' on the CC command
line. This causes issues as the libapi, libsubcmd, libtraceevent,
libbpf headers are all found via this path, making it impossible to
override include behavior. Change the libsubcmd build mirroring the
libbpf build, so that it is installed in a directory along with its
headers. A later change will modify the include behavior.

Subject: [PATCH 0561/1480] perf build: Install libtraceevent locally when
 building

The perf build currently has a '-Itools/lib' on the CC command
line. This causes issues as the libapi, libsubcmd, libtraceevent,
libbpf headers are all found via this path, making it impossible to
override include behavior.

Change the libtraceevent build mirroring the libbpf, libsubcmd, libapi
and libperf build, so that it is installed in a directory along with its
headers. A later change will modify the include behavior.

Similarly, the plugins are now installed into libtraceevent_plugins
except they have no header files.

Change the libsymbol build mirroring the libbpf, libsubcmd, libapi,
libperf and libtraceevent build, so that it is installed in a directory
along with its headers.

A later change will modify the include behavior.  Don't build kallsyms.o
as part of util as this will lead to duplicate definitions. Add
kallsym's directory to the MANIFEST rather than individual files, so
that the Build and Makefile are added to a source tar ball.

Subject: [PATCH 0566/1480] perf expr: Tidy hashmap dependency

hashmap.h comes from libbpf but isn't installed with its
headers. Always use the header file of the code in util. Change the
hashmap.h dependency in expr.h to a forward declaration, add the
necessary header file includes in the C files.

From: Ian Rogers <irogers@google.com>

Subject: [PATCH 0567/1480] perf thread_map: Reduce exposure of libperf
 internal API

Remove unnecessary include of internal threadmap.h and refcount.h in
thread_map.h. Switch to using public APIs when possible or including
the internal header file in the C file. Fix a transitive dependency in
openat-syscall.c broken by the clean up.

Subject: [PATCH 0568/1480] perf cpumap: Tidy libperf includes

Use public API when possible, don't include internal API in header
files in evsel.h. Fix any related breakages.

Committer note:

There was one missing case, when building for arm64:

  arch/arm64/util/pmu.c: In function 'pmu_events_table__find':
  arch/arm64/util/pmu.c:18:30: error: invalid use of undefined type 'struct perf_cpu_map'
     18 |                 if (pmu->cpus->nr != cpu__max_cpu().cpu)
        |                              ^~

Fix it by adding one more exception, including <internal/cpumap.h>

Subject: [PATCH 0580/1480] vmlinux.lds.h: fix BOUNDED_SECTION_(PRE|POST)_LABEL
 macros

Commit 2f465b921bb8 ("vmlinux.lds.h: place optional header space in BOUNDED_SECTION")

added BOUNDED_SECTION_(PRE|POST)_LABEL macros, encapsulating the basic
boilerplate to KEEP/pack records into a section, and to mark the begin
and end of the section with linker-symbols.

But it tried to do extra, adding KEEP(*(.gnu.linkonce.##_sec_)) to
optionally reserve a header record in front of the data.  It wrongly
placed the KEEP after the linker-symbol starting the section,
so if a header was added, it would wind up in the data.

Moving the KEEP to the "correct" place proved brittle, and too clever
by half.  The obvious safe fix is to remove the KEEP and restore the
plain old boilerplate.  The header can be added later, with separate
macros.

Also, the macro var-names: _s_, _e_ are nearly invisible, change them
to more obvious names: _BEGIN_, _END_

Subject: [PATCH 0581/1480] vmlinux.lds.h: add HEADERED_SECTION_* macros

These macros elaborate on BOUNDED_SECTION_(PRE|POST)_LABEL macros,
prepending an optional KEEP(.gnu.linkonce##_sec_) reservation, and a
linker-symbol to address it.

This allows a developer to define a header struct (which must fit with
the section's base struct-type), and could contain:

1- fields whose value is common to the entire set of data-records.
   This allows the header & data structs to specialize, complement
   each other, and shrink.

2- an uplink pointer to an organizing struct
   which refs other related/sub data-tables
   header record is addressable via the extern'd header linker-symbol

Once the linker-symbols created by the macro are ref'd extern in code,
that code can compute a record's index (ptr - start) in the "primary"
table, then use it to index into the related/sub tables.  Adding a
primary.map_* field foreach sub-table would then allow deduplication
and remapping of that sub-table.

This is aimed at dyndbg's struct _ddebug __dyndbg[] section, whose 3
columns: function, file, module are 50%, 90%, 100% redundant.  The
module column is fully recoverable after dynamic_debug_init() saves it
to each ddebug_table.module as the builtin __dyndbg[] table is parsed.

Given that those 3 columns use 24/56 of a _ddebug record, a dyndbg=y
kernel with ~5k callsites could reduce kernel memory substantially.
Returning that memory to the kernel buddy-allocator? is then possible.

Subject: [PATCH 0583/1480] staging: r8188eu: convert aes_cipher() to void

The function aes_cipher() returns always _SUCCESS and its callers
do not use the return value. So we can convert the return type to
void and get rid of another use of _SUCCESS.

Convert the function rtw_xmit_resource_alloc() away from returning
_FAIL or _SUCCESS which uses inverted error logic. Use the common
error logic instead. Return 0 for success and negative values for
failure.

From c7bf6d33d095637fb78ba484a181d17bc1a73a68 Mon Sep 17 00:00:00 2001
From: Philipp Hortmann <philipp.g.hortmann@gmail.com>
Date: Sun, 13 Nov 2022 05:35:12 +0100
Subject: [PATCH 0588/1480] staging: rtl8192e: Rename Regdot11HTOper..,
 bSupportM.. and PowerSaveCo..

Rename variable Regdot11HTOperationalRateSet to
reg_dot11ht_oper_rate_set, bSupportMode to support_mode and
PowerSaveControl to pwr_save_ctrl to avoid CamelCase which is not accepted
by checkpatch. Fix unnecessary parentheses warning from checkpatch when
used with this variables.

Subject: [PATCH 0589/1480] staging: rtl8192e: Rename Regdot11TxHT..,
 dot11HTOpera.. and RegHTSuppRa..

Rename variable Regdot11TxHTOperationalRateSet to
reg_dot11tx_ht_oper_rate_set, dot11HTOperationalRateSet to
dot11ht_oper_rate_set and RegHTSuppRateSet to reg_ht_supp_rate_set to
avoid CamelCase which is not accepted by checkpatch.

Subject: [PATCH 0591/1480] staging: rtl8192e: Rename RFInProgres.., bEnableHT
 and RegChannelPlan

Rename variable RFInProgressTimeOut to rf_in_progress_timeout, bEnableHT
to enable_ht and RegChannelPlan to reg_chnl_plan to avoid CamelCase which
is not accepted by checkpatch.

From 8e5d08ceb8db933bdb1f60772984ffc166d2eb55 Mon Sep 17 00:00:00 2001
From: Philipp Hortmann <philipp.g.hortmann@gmail.com>
Date: Sun, 13 Nov 2022 05:35:55 +0100
Subject: [PATCH 0593/1480] staging: rtl8192e: Rename bNetPromisc..,
 IntelPromiscu.. and bPromiscu..

Rename variable bNetPromiscuousMode to net_promiscuous_md,
IntelPromiscuousModeInfo to intel_promiscuous_md_info and bPromiscuousOn
to promiscuous_on to avoid CamelCase which is not accepted by checkpatch.

Subject: [PATCH 0594/1480] staging: rtl8192e: Rename bFilterSour..,
 CCKPresentAt.. and ResetProg..

Rename variable bFilterSourceStationFrame to fltr_src_sta_frame,
CCKPresentAttentuation to cck_present_attn and ResetProgress to
rst_progress to avoid CamelCase which is not accepted by checkpatch.

From: Ian Rogers <irogers@google.com>
Date: Wed, 16 Nov 2022 16:43:51 -0800
Subject: [PATCH 0597/1480] tools lib api: Clean up install_headers

Add missing backslash that caused an install command to always appear
in build output. Make the install headers more specific.

Subject: [PATCH 0598/1480] tools lib bpf: Avoid install_headers make warning

The perf build makes the install_headers target, however, as there is
no action for this target a warning is always produced of:

make[3]: Nothing to be done for 'install_headers'.

Solve this by adding a display of 'INSTALL libbpf_headers'.

Subject: [PATCH 0603/1480] perf test: Add -w/--workload option

The -w/--workload option is to run a simple workload used by testing.
This adds a basic framework to run the workloads and 'noploop' workload
as an example.

  $ perf test -w noploop

The noploop does a loop doing nothing (NOP) for a second by default.
It can have an optional argument to specify the time in seconds.

Date: Wed, 16 Nov 2022 15:38:45 -0800
Subject: [PATCH 0605/1480] perf test: Add 'thloop' test workload

The thloop is similar to noploop but runs in two threads.  This is
needed to verify perf record --per-thread to handle multi-threaded
programs properly.

  $ perf test -w thloop

It also takes an optional argument to specify runtime in seconds
(default: 1).

Smatch report warning as follows:

drivers/staging/vme_user/vme_tsi148.c:1757 tsi148_dma_list_add() warn:
  '&entry->list' not removed from list

In tsi148_dma_list_add(), the error path "goto err_dma" will not
remove entry->list from list->entries, but entry will be freed,
then list traversal may cause UAF.

Fix by removeing it from list->entries before free().

Subject: [PATCH 0611/1480] vc04_services: bcm2835-camera: Use bool values for
 mmal_fmt.remove_padding

mmal_fmt.remove_padding is defined as a boolean type hence, use boolean
values for it instead of 0/1 integers. This enhances code readability.

Subject: [PATCH 0615/1480] usb: fotg210: Fix Kconfig for USB host modules

The kernel robot reports a link failure when activating the
FOTG210 host subdriver with =y on a system where the USB host
core is a module (CONFIG_USB=m).

This is a bit of special case, so mimic the Kconfig incantations
from DWC3: let the subdrivers for host or peripheral depend
on the host or gadget support being =y or the same as the
FOTG210 core itself.

This should ensure that either:

- The host (CONFIG_USB) or gadget (CONFIG_GADGET) is compiled
  in and then the FOTG210 can be either module or compiled
  in.

- The host or gadget is modular, and then the FOTG210 module
  must be a module too, or we cannot resolve the symbols
  at link time.

Subject: [PATCH 0626/1480] usb: typec: tcpci: fix of node refcount leak in
 tcpci_register_port()

I got the following report while doing device(mt6370-tcpc) load
test with CONFIG_OF_UNITTEST and CONFIG_OF_DYNAMIC enabled:

  OF: ERROR: memory leak, expected refcount 1 instead of 2,
  of_node_get()/of_node_put() unbalanced - destroy cset entry:
  attach overlay node /i2c/pmic@34/tcpc/connector

The 'fwnode' set in tcpci_parse_config() which is called
in tcpci_register_port(), its node refcount is increased
in device_get_named_child_node(). It needs be put while
exiting, so call fwnode_handle_put() in the error path of
tcpci_register_port() and in tcpci_unregister_port() to
avoid leak.

There is error log when add a usb3 root hub without ports:
"hub 4-0:1.0: config failed, hub doesn't have any ports! (err -19)"

so omit the shared hcd if either of the root hubs has no ports, but
usually there is no usb3 port.

released that fwnode though. Fix that by moving fwnode_handle_put in the

Subject: [PATCH 0632/1480] usb: musb: omap2430: Fix probe regression for
 missing resources

Probe for omap2430 glue layer is now broken for interrupt resources in
all cases.

Commit  239071064732 ("partially Revert "usb: musb: Set the DT node on the
child device"") broke probing for SoCs using ti-sysc interconnect target
module as the dt node is not found.

Commit a1a2b7125e10 ("of/platform: Drop static setup of IRQ resource from
DT core") caused omap3 to fail with error "-ENXIO: IRQ mc not found" as
the IRQ resources are no longer automatically populated from devicetree.

Let's fix the issues by calling device_set_of_node_from_dev() only if the
SoC has been updated to probe with ti-sysc. And for legacy SoCs, let's
populate the resources manually as needed.

Note that once we have updated the SoCs to probe with proper devicetree
data in all cases, this is no longer needed. But doing that requires
patching both devicetree and SoC code, so let's fix the probe issues first.

Subject: [PATCH 0633/1480] usb: dwc3: improve the config dependency of
 USB_DWC3_XILINX

A request to Manish Narani (see Link) asked for clarification of the
reference to the config ARCH_VERSAL in the support of Xilinx SoCs with
DesignWare Core USB3 IP.

As there is no response, clean up the reference to the non-existing config
symbol. While at it, follow up on Felipe Balbi's request to add the
alternative COMPILE_TEST dependency.

Subject: [PATCH 0634/1480] extcon: usbc-tusb320: Update state on probe even if
 no IRQ pending
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently this driver triggers extcon and typec state update in its
probe function, to read out current state reported by the chip and
report the correct state to upper layers. This synchronization is
performed correctly, but only in case the chip indicates a pending
interrupt in reg09 register.

This fails to cover the situation where all interrupts reported by
the chip were already handled by Linux before reboot, then the system
rebooted, and then Linux starts again. In this case, the TUSB320 no
longer reports any interrupts in reg09, and the state update does not
perform any update as it depends on that interrupt indication.

Fix this by turning tusb320_irq_handler() into a thin wrapper around
tusb320_state_update_handler(), where the later now contains the bulk
of the code of tusb320_irq_handler(), but adds new function parameter
"force_update". The "force_update" parameter can be used by the probe
function to assure that the state synchronization is always performed,
independent of the interrupt indicated in reg09. The interrupt handler
tusb320_irq_handler() callback uses force_update=false to avoid state
updates on potential spurious interrupts and retain current behavior.

Subject: [PATCH 0635/1480] USB: gadget: Fix use-after-free during usb config
 switch

In the process of switching USB config from rndis to other config,
if the hardware does not support the ->pullup callback, or the
hardware encounters a low probability fault, both of them may cause
the ->pullup callback to fail, which will then cause a system panic
(use after free).

The gadget drivers sometimes need to be unloaded regardless of the
hardware's behavior.

Analysis as follows:
=======================================================================
(1) write /config/usb_gadget/g1/UDC "none"

gether_disconnect+0x2c/0x1f8
rndis_disable+0x4c/0x74
composite_disconnect+0x74/0xb0
configfs_composite_disconnect+0x60/0x7c
usb_gadget_disconnect+0x70/0x124
usb_gadget_unregister_driver+0xc8/0x1d8
gadget_dev_desc_UDC_store+0xec/0x1e4

(2) rm /config/usb_gadget/g1/configs/b.1/f1

rndis_deregister+0x28/0x54
rndis_free+0x44/0x7c
usb_put_function+0x14/0x1c
config_usb_cfg_unlink+0xc4/0xe0
configfs_unlink+0x124/0x1c8
vfs_unlink+0x114/0x1dc

(3) rmdir /config/usb_gadget/g1/functions/rndis.gs4

panic+0x1fc/0x3d0
do_page_fault+0xa8/0x46c
do_mem_abort+0x3c/0xac
el1_sync_handler+0x40/0x78
0xffffff801138f880
rndis_close+0x28/0x34
eth_stop+0x74/0x110
dev_close_many+0x48/0x194
rollback_registered_many+0x118/0x814
unregister_netdev+0x20/0x30
gether_cleanup+0x1c/0x38
rndis_attr_release+0xc/0x14
kref_put+0x74/0xb8
configfs_rmdir+0x314/0x374

If gadget->ops->pullup() return an error, function rndis_close() will be
called, then it will causes a use-after-free problem.

Subject: [PATCH 0649/1480] kobject: make kobject_get_ownership() take a
 constant kobject *

The call, kobject_get_ownership(), does not modify the kobject passed
into it, so make it const.  This propagates down into the kobj_type
function callbacks so make the kobject passed into them also const,
ensuring that nothing in the kobject is being changed here.

This helps make it more obvious what calls and callbacks do, and do not,
modify structures passed to them.

Date: Mon, 21 Nov 2022 10:46:46 +0100
Subject: [PATCH 0650/1480] kobject: make kobject_namespace take a const *

kobject_namespace() should take a const *kobject as it does not modify
the kobject passed to it.  Change that, and the functions
kobj_child_ns_ops() and kobj_ns_ops() needed to also be changed to const
*.

Instead of self-defined struct altera_jtaguart::imr, use preexisting
uart_port::read_status_mask.

Note that imr was ulong. But there is no reason for that, its values are
uints. And readl/writel's are used to read it/write to it.

Subject: [PATCH 0659/1480] serial: amba-pl011: avoid SBSA UART accessing DMACR
 register

Chapter "B Generic UART" in "ARM Server Base System Architecture" [1]
documentation describes a generic UART interface. Such generic UART
does not support DMA. In current code, sbsa_uart_pops and
amba_pl011_pops share the same stop_rx operation, which will invoke
pl011_dma_rx_stop, leading to an access of the DMACR register. This
commit adds a using_rx_dma check in pl011_dma_rx_stop to avoid the
access to DMACR register for SBSA UARTs which does not support DMA.

When the kernel enables DMA engine with "CONFIG_DMA_ENGINE=y", Linux
SBSA PL011 driver will access PL011 DMACR register in some functions.
For most real SBSA Pl011 hardware implementations, the DMACR write
behaviour will be ignored. So these DMACR operations will not cause
obvious problems. But for some virtual SBSA PL011 hardware, like Xen
virtual SBSA PL011 (vpl011) device, the behaviour might be different.
Xen vpl011 emulation will inject a data abort to guest, when guest is
accessing an unimplemented UART register. As Xen VPL011 is SBSA
compatible, it will not implement DMACR register. So when Linux SBSA
PL011 driver access DMACR register, it will get an unhandled data abort
fault and the application will get a segmentation fault:

This has been discussed in the Xen community, and we think it should fix
this in Linux. See [2] for more information.

Subject: [PATCH 0661/1480] dt-bindings: serial: xlnx,opb-uartlite: Drop
 'contains' from 'xlnx,use-parity'

'contains' applies to arrays, but 'xlnx,use-parity' is a scalar. So drop
'contains' from the 'if' schema.

Subject: [PATCH 0662/1480] serial: stm32: move dma_request_chan() before
 clk_prepare_enable()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If dma_request_chan() returns a PROBE_DEFER error, clk_disable_unprepare()
will be called and USART clock will be disabled. But early console can be
still active on the same USART.

While moving dma_request_chan() before clk_prepare_enable(), the clock
won't be taken in case of a DMA PROBE_DEFER error, and so it doesn't need
to be disabled. Then USART is still clocked for early console.

Subject: [PATCH 0663/1480] tty: synclink_gt: unwind actions in error path of
 net device open

Resent again, last attempt still altered the plain text.

Zhengchao Shao <shaozhengchao@huawei.com> identified by inspection bugs in the error path of hdlcdev_open() in synclink_gt.c

The function did not fully unwind actions in the error path. The use of try_module_get()/module_put() is unnecessary, potentially hazardous and is removed. The synclink_gt driver is already pinned any point the net device is registered, a requirement for calling this entry point.

The call hdlc_open() to init the generic HDLC layer is moved to after driver level init/checks and proper rollback of previous actions is added. This is a more sensible ordering as the most common error paths are at the driver level and the driver level rollbacks require less processing than hdlc_open()/hdlc_close().

This has been tested with supported hardware.

Subject: [PATCH 0665/1480] tty: serial: fsl_lpuart: enable wakeup source for
 lpuart

LPUART supports both synchronous wakeup and asynchronous wakeup(wakeup
the system when the UART clocks are shut-off), the synchronous wakeup is
configured by UARTCTRL_RIE interrupt, and the asynchronous wakeup is
configured by UARTBAUD_RXEDGIE interrupt.

Add lpuart_uport_is_active() to determine if the uart port needs to get
into the suspend states, also add lpuart_suspend_noirq() and
lpuart_resume_noirq() to enable and disable the wakeup irq bits if the
uart port needs to be set as wakeup source.

When use lpuart with DMA mode, it still needs to switch to the cpu mode
in .suspend() that enable cpu interrupts RIE and RXEDGIE as wakeup
source, after system resume back, needs to setup DMA again, .resume()
will share the HW setup code with .startup(), so abstract the same code
to the api like lpuart32_hw_setup().

Subject: [PATCH 0668/1480] serial: pch: Fix PCI device refcount leak in
 pch_request_dma()

As comment of pci_get_slot() says, it returns a pci_device with its
refcount increased. The caller must decrement the reference count by
calling pci_dev_put().

Since 'dma_dev' is only used to filter the channel in filter(), we can
call pci_dev_put() before exiting from pch_request_dma(). Add the
missing pci_dev_put() for the normal and error path.

Subject: [PATCH 0672/1480] serial: atmel: cleanup atmel_start+stop_tx()

Define local variables holding information about whether pdc or dma is
used in the HW. These are retested several times by calls to
atmel_use_pdc_tx() and atmel_use_dma_tx(). So to make the code more
readable, simply cache the values.

This is also a preparatory patch for the next one (where is_pdc is used
once more in atmel_stop_tx()).

Subject: [PATCH 0673/1480] serial: atmel: don't stop the transmitter when
 doing PIO

Writing ATMEL_US_TXDIS to ATMEL_US_CR makes the transmitter NOT to send
the just queued character. This means when the character is last and
uart calls ops->stop_tx(), the character is not sent at all.

The usart datasheet is not much specific on this, it just says the
transmitter is stopped. But apparently, the character is dropped. So
we should stop the transmitter only for DMA and PDC transfers to not
send any more characters. For PIO, this is unexpected and deviates from
other drivers. In particular, the below referenced commit broke TX as it
added a call to ->stop_tx() after the very last character written to the
transmitter.

So fix this by limiting the write of ATMEL_US_TXDIS to DMA transfers
only.

Even there, I don't know if it is correctly implemented. Are all the
queued characters sent once ->start_tx() is called? Anyone tested flow
control -- be it hard (RTSCTS) or the soft (XOFF/XON) one?

Subject: [PATCH 0674/1480] perf test: Add 'leafloop' test workload

The leafloop workload is to run an infinite loop in the test_leaf
function.  This is needed for the ARM fp callgraph test to verify if it
gets the correct callchains.

  $ perf test -w leafloop

Committer notes:

Add a:

  -U_FORTIFY_SOURCE

to the leafloop CFLAGS as the main perf flags set it and it requires
building with optimization, and this new test has a -O0.

Subject: [PATCH 0676/1480] perf test: Add 'sqrtloop' test workload

The sqrtloop creates a child process to run an infinite loop calling
sqrt() with rand().  This is needed for ARM SPE fork test.

  $ perf test -w sqrtloop

It can take an optional argument to specify how long it will run in
seconds (default: 1).

Committer notes:

Explicitely ignored the sqrt() return to fix the build on systems where
the compiler complains it isn't being used.

And added a sqrtloop specific CFLAGS to disable optimizations to make
this a bit more robust wrt dead code elimination.

Doing that a -U_FORTIFY_SOURCE needs to be added, as -O0 is incompatible
with it.

Subject: [PATCH 0678/1480] perf test: Add 'brstack' test workload

The brstack is to run different kinds of branches repeatedly.  This is
necessary for brstack test case to verify if it has correct branch info.

  $ perf test -w brstack

I renamed the internal functions to have brstack_ prefix as it's too
generic name.

Add a -U_FORTIFY_SOURCE to the brstack CFLAGS, as the main perf flags
set it and it requires building with optimization, and this new test has
a -O0.

Subject: [PATCH 0680/1480] perf test: Add 'datasym' test workload

The datasym workload is to check if perf mem command gets the data
addresses precisely.  This is needed for data symbol test.

  $ perf test -w datasym

I had to keep the buf1 in the data section, otherwise it could end
up in the BSS and was mmaped as a separate //anon region, then it
was not symbolized at all.  It needs to be fixed separately.

Committer notes:

Add a -U _FORTIFY_SOURCE to the datasym CFLAGS, as the main perf flags
set it and it requires building with optimization, and this new test has
a -O0.

From e5c6109f4813246aa21e2c441e3cde549efa1f18 Mon Sep 17 00:00:00 2001
From: Ian Rogers <irogers@google.com>
Date: Mon, 14 Nov 2022 13:07:22 -0800
Subject: [PATCH 0683/1480] perf list: Reorganize to use callbacks to allow
 honouring command line options
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Rather than controlling the list output with passed flags, add
callbacks that are called when an event or metric are
encountered. State is passed to the callback so that command line
options can be respected, alternatively the callbacks can be changed.

Fix a few bugs:
 - wordwrap to columns metric descriptions and expressions;
 - remove unnecessary whitespace after PMU event names;
 - the metric filter is a glob but matched using strstr which will
   always fail, switch to using a proper globmatch,
 - the detail flag gives details for extra kernel PMU events like
   branch-instructions.

In metricgroup.c switch from struct mep being a rbtree of metricgroups
containing a list of metrics, to the tree directly containing all the
metrics. In general the alias for a name is passed to the print
routine rather than being contained in the name with OR.

Committer notes:

Check the asprint() return to address this on fedora 36:

  util/print-events.c: In function ‘print_sdt_events’:
  util/print-events.c:183:33: error: ignoring return value of ‘asprintf’ declared with attribute ‘warn_unused_result’ [-Werror=unused-result]
    183 |                                 asprintf(&evt_name, "%s@%s(%.12s)", sdt_name->s, path, bid);
        |                                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  cc1: all warnings being treated as errors

  $ gcc --version | head -1
  gcc (GCC) 12.2.1 20220819 (Red Hat 12.2.1-2)
  $

Fix ps.pmu_glob setting when dealing with *:* events, it was being left
with a freed pointer that then at the end of cmd_list() would be double
freed.

Check if pmu_name is NULL in default_print_event() before calling
strglobmatch(pmu_name, ...) to avoid a segfault.

Subject: [PATCH 0684/1480] perf list: Add JSON output option

Output events and metrics in a JSON format by overriding the print
callbacks. Currently other command line options aren't supported and
metrics are repeated once per metric group.

Committer testing:

Subject: [PATCH 0686/1480] perf trace: Return error if a system call doesn't
 exist

When a system call is not detected, the reason is either because the
system call ID is out of scope or failure to find the corresponding path
in the sysfs, trace__read_syscall_info() returns zero.  Finally, without
returning an error value it introduces confusion for the caller.

This patch lets the function trace__read_syscall_info() to return
-EEXIST when a system call doesn't exist.

Subject: [PATCH 0687/1480] perf trace: Handle failure when trace point folder
 is missed

On Arm64 a case is perf tools fails to find the corresponding trace
point folder for system calls listed in the table 'syscalltbl_arm64',
e.g. the generated system call table contains "lookup_dcookie" but we
cannot find out the matched trace point folder for it.

We need to figure out if there have any issue for the generated system
call table, on the other hand, we need to handle the case when trace
point folder is missed under sysfs, this patch sets the flag
syscall::nonexistent as true and returns the error from
trace__read_syscall_info().

Another problem is for trace__syscall_info(), it returns two different
values if a system call doesn't exist: at the first time calling
trace__syscall_info() it returns NULL when the system call doesn't exist,
later if call trace__syscall_info() again for the same missed system
call, it returns pointer of syscall.  trace__syscall_info() checks the
condition 'syscalls.table[id].name == NULL', but the name will be
assigned in the first invoking even the system call is not found.

So checking system call's name in trace__syscall_info() is not the right
thing to do, this patch simply checks flag syscall::nonexistent to make
decision if a system call exists or not, finally trace__syscall_info()
returns the consistent result (NULL) if a system call doesn't existed.

Subject: [PATCH 0689/1480] perf trace: Remove unused bpf map 'syscalls'

augmented_raw_syscalls.c defines the bpf map 'syscalls' which is
initialized by perf tool in user space to indicate which system calls
are enabled for tracing, on the other flip eBPF program relies on the
map to filter out the trace events which are not enabled.

The map also includes a field 'string_args_len[6]' which presents the
string length if the corresponding argument is a string type.

Now the map 'syscalls' is not used, bpf program doesn't use it as filter
anymore, this is replaced by using the function bpf_tail_call() and
PROG_ARRAY syscalls map.  And we don't need to explicitly set the string
length anymore, bpf_probe_read_str() is smart to copy the string and
return string length.

Therefore, it's safe to remove the bpf map 'syscalls'.

To consolidate the code, this patch removes the definition of map
'syscalls' from augmented_raw_syscalls.c and drops code for using
the map in the perf trace.

Note, since function trace__set_ev_qualifier_bpf_filter() is removed,
calling trace__init_syscall_bpf_progs() from it is also removed.  We
don't need to worry it because trace__init_syscall_bpf_progs() is
still invoked from trace__init_syscalls_bpf_prog_array_maps() for
initialization the system call's bpf program callback.

Subject: [PATCH 0691/1480] perf inject: Set PERF_RECORD_MISC_BUILD_ID_SIZE

With perf inject -b, it synthesizes build-id event for DSOs.  But it
missed to set the size and resulted in having trailing zeros.

As perf record sets the size in write_build_id(), let's set the size
here as well.

Subject: [PATCH 0692/1480] perf test: Fix record test on KVM guests

Using precise flag with br_inst_retired.near_call causes the test fail
on KVM guests, even when the guests have PMU forwarding enabled and the
event itself is supported.

Remove the precise flag in order to make the test work on KVM guests.

Subject: [PATCH 0694/1480] perf lock contention: Do not use BPF task local
 storage

It caused some troubles when a lock inside kmalloc is contended
because task local storage would allocate memory using kmalloc.
It'd create a recusion and even crash in my system.

There could be a couple of workarounds but I think the simplest
one is to use a pre-allocated hash map.  We could fix the task
local storage to use the safe BPF allocator, but it takes time
so let's change this until it happens actually.

RAZWI is optionally handled as part of the generic QM SEI error

Only the first page fault will be saved.
Besides the address which caused the page fault, the driver captures
all of the mmu user mappings.
User can retrieve this data via the new uapi (new opcode in INFO ioctl).

pf was an abbreviation for prefetch but because pf already stands
for 'physical function', we decided to change it to 'prefetch'.

Subject: [PATCH 0705/1480] habanalabs: skip idle status check if reset on
 device release

If reset upon device release is enabled, there is no need to check the
device idle status in hpriv_release(), because device is going to be
reset in any case.

 non-operational

Unregistering eventfd is for releasing host resources and doesn't
involve an access to the device. As such, there is no reason to disallow
it when device isn't operational.

Subject: [PATCH 0707/1480] habanalabs: move reset workqueue to be under
 hl_device

'struct hl_device_reset_work' is used as a wrapper for the reset work
and its parameters, including the reset workqueue on which it runs.
In a future commit, another reset related work with similar parameters
is going to be added, but it won't use the reset workqueue.

As in any case there is a single reset workqueue, and to allow the resue
of this structure, move the reset workqueue to 'struct hl_device'.

Subject: [PATCH 0709/1480] habanalabs/gaudi2: capture RAZWI information

Added function to calculate possible engines which caused
RAZWI (read-only zero, write ignored), from a given router id or
module index.

When getting RAZWI via PSOC IP, first the router id is calculated
and then the possible engines that caused the RAZWI are calculated.

There is a possibility that the RAZWI initiator is not an engine. In
that case, it will not be included in possible engines as it
doesn't have an engine id.

RAZWI information is captured when receiving event from engine or via
PSOC IP.

Subject: [PATCH 0713/1480] habanalabs: fix using freed pointer

The code uses the pointer for trace purpose (without actually
dereference it) but still get static analysis warning.
This patch eliminate the warning.

Subject: [PATCH 0714/1480] habanalabs: allow setting HBM BAR to other regions

Up until now the use-case in the driver was that the HBM is accessed
using the HBM BAR, yet the BAR sometimes cannot cover the whole HBM and
so we needed to set the BAR to other HBM offset.
Now we are facing the need to access other PCI memory regions that can
be covered by the HBM BAR.
To answer that we are allowing the caller to determine if the HBM BAR
need to be set or not regardless of the PCI memory region.

Subject: [PATCH 0718/1480] habanalabs: add support for graceful hard reset

Calling hl_device_reset() for a hard reset will lead to a quite
immediate device reset and to killing user process.
For resets that follow errors, it disables the option to debug the
errors on both the device side and the user application side.

This patch adds a 'graceful hard reset' option and a new
hl_device_cond_reset() function.
Under some conditions, mainly if there is no user process or if he is
not registered to driver notifications, this function will execute hard
reset as usual.
Otherwise, the reset will be postponed and a notification will be sent
to user, to let him perform post-error actions and then to release the
device, after which reset will take place.

If device is not released by user in some defined time, a watchdog work
will execute the reset in any case.

Subject: [PATCH 0719/1480] habanalabs: add an option to control watchdog
 timeout via debugfs

Add an option to control the timeout value for the driver's watchdog
of the reset process. The timeout represents the amount of the user
has to close his process once he gets a device reset notification from
the driver.

Subject: [PATCH 0723/1480] habanalabs: no consecutive err when user context is
 enabled

Consecutive error protects a device reset loop from being triggered
due to h/w issues and enters the device into an unavailable state.
When user may cause the error, an unavailable state
will prevent the user from running its workloads.

The commit prevents entering consecutive state when a user context
is enabled.

Subject: [PATCH 0725/1480] habanalabs: fix PCIe access to SRAM via debugfs

hl_access_sram_dram_region() uses a region base which is set within the
hl_set_dram_bar() function. However, for SRAM access this function is
not called, and we end up with a wrong value of region base and with a
bad calculated address.
Fix it by initializing the region base value independently of whether
hl_set_dram_bar() is called or not.

Subject: [PATCH 0730/1480] habanalabs: use single threaded WQ for event
 handling

Creating event queue workqueue using alloc_workqueue made it run in
multi threaded mode, which caused parallel dumping of events as well as
parallel events notifying to user, causing logs with multiple
events to be out of order.

Fixed by creating event queue workqueue as single threaded work queue.

Subject: [PATCH 0742/1480] habanalabs/gaudi2: return to reset upon SM SEI
 BRESP error

Due to a H/W issue in the LBW path to the PCIE_DBI MSI-X doorbell, there
were false sporadic error responses in SM when it was configured to
write to there, and hence no reset was done as part of handling the
relevant event.
Now that the virtual MSI-X doorbell is used, such errors in SM are not
expected and reset shouldn't be skipped.

Subject: [PATCH 0743/1480] habanalabs: reset device if still in use when
 released

If the device file is released while a context is still held, it won't
be possible to reopen it until the context is eventually released.
If that doesn't happen, only a device reset will revert it back to an
operational state, i.e. need to wait for a CS timeout or an error, or to
wait for an external intervention of injecting a reset via sysfs.

At this stage, after the device was released by user, context is held
either because of CS which were left running on the device and are not
relevant anymore, or due to missing cleanup steps from user side.

All of this is in any case handled in the device reset flow, so initiate
the reset at this point instead of waiting for it.

Subject: [PATCH 0745/1480] habanalabs: extend process wait timeout in device
 fine

Processes that use our device are likely to use at the same time other
devices such as remote storage.

In case our device is removed and a user process is still using the
device, we need to kill the user process. However, if that process
has a thread waiting for i/o to complete on remote storage, for example,
the process won't terminate.

Let's give it enough time to terminate before giving up.

This allows several 'ORed' vals and masks to be set at once
The patch also fixes wrong usage of RMWREG32 by replacing

Subject: [PATCH 0752/1480] habanalabs: print context refcount value if hard
 reset fails

Failing to kill a user process during a hard reset can be due to a
reference to the user context which isn't released.
To make it easier to understand if this the reason for the failure and
not something else, add a print of the context refcount value.

Subject: [PATCH 0753/1480] habanalabs: don't put context in
 hl_encaps_handle_do_release_sob()

hl_encaps_handle_do_release_sob() can be called only when the last
reference to the context object is released and hl_ctx_do_release() is
initiated, and therefore it shouldn't call hl_ctx_put().

Subject: [PATCH 0754/1480] habanalabs: clear non-released encapsulated signals

Reserved encapsulated signals which were not released hold the context
refcount, leading to a failure when killing the user process on device
reset or device fini.
Add the release of these left signals in the CS roll-back process.

Subject: [PATCH 0755/1480] habanalabs: make print of engines idle mask more
 readable

The engines idle mask was increased to be an array of 4 u64 entries.
To make the print of this mask more readable, remove the "0x" prefix,
and zero-pad each u64 to 16 bytes if either it isn't zero or if any of
the higher-order u64's is not zero.

From 40eb28dc17f87cfac69d7755447039e92ac5fbda Mon Sep 17 00:00:00 2001

Subject: [PATCH 0759/1480] device property: Get rid of
 __PROPERTY_ENTRY_ARRAY_EL*SIZE*()

First of all, _ELEMENT_SIZE() repeats existing sizeof_field() macro.
Second, usage of _ARRAY_ELSIZE_LEN() adds unnecessary indirection
to the data layout. It's more understandable when the data structure
is placed explicitly. That said, get rid of those macros by replacing
them with the existing helper and explicit data structure layout.

Subject: [PATCH 0760/1480] device property: Move PROPERTY_ENTRY_BOOL() a bit
 down

Let's order ARRAY and non-ARRAY macros in the same way. The
PROPERTY_ENTRY_BOOL() is special, move it a bit down in the
code so it won't break ordering of the rest.

Subject: [PATCH 0764/1480] mei: add timeout to send

When driver wakes up the firmware from the low power state,
it is sending a memory ready message.
The send is done via synchronous/blocking function to ensure
that firmware is in ready state. However, in case of firmware
undergoing reset send might be block forever.
To address this issue a timeout is added to blocking
write command on the internal bus.

Introduce the __mei_cl_send_timeout function to use instead of
__mei_cl_send in cases where timeout is required.
The mei_cl_write has only two callers and there is no need to split
it into two functions.

@unit_mutex protects @unit from being freed, so obviously it should be
released after @unit is used, and not before.

This is a follow-up to commit 282a4b71816b ("char: xillybus: Prevent
use-after-free due to race condition") which ensures, among others, the
protection of @private_data after @unit_mutex has been released.

Subject: [PATCH 0768/1480] virtio_console: Introduce an ID allocator for
 virtual console numbers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When a virtio console port is initialized, it is registered as an hvc
console using a virtual console number. If a KVM guest is started with
multiple virtio console devices, the same vtermno (or virtual console
number) can be used to allocate different hvc consoles, which leads to
various communication problems later on.

This is also reported in debugfs :

  # grep vtermno /sys/kernel/debug/virtio-ports/*
  /sys/kernel/debug/virtio-ports/vport1p1:console_vtermno: 1
  /sys/kernel/debug/virtio-ports/vport2p1:console_vtermno: 1
  /sys/kernel/debug/virtio-ports/vport3p1:console_vtermno: 2
  /sys/kernel/debug/virtio-ports/vport4p1:console_vtermno: 3

Replace the next_vtermno global with an ID allocator and start the
allocation at 1 as it is today. Also recycle IDs when a console port
is removed.

Subject: [PATCH 0770/1480] nvmem: stm32: add warning when upper OTPs are
 updated

As the upper OTPs are ECC protected, they support only one 32 bits word
programming.
For a second modification of this word, these ECC become invalid and
this OTP will be no more accessible, the shadowed value is invalid.

This patch adds a warning to indicate an upper OTP update, because this
operation is dangerous as OTP is not locked by the driver after the first
update to avoid a second update.

Despite not being listed nor required within the top level nvmem yaml
file, the "compatible" property is mandatory and is actually enforced by
all the nvmem provider bindings.

Unfortunately, the lack of compatible in the nvmem.yaml to level
description file lead to the example not matching anything and thus not
being checked at all.

Let's pick a compatible almost randomly (one which is already used with
the qfprom label) to make the example at least valid on a semantic
point of view and getting it checked.

Subject: [PATCH 0777/1480] dt-bindings: nvmem: Introduce the nvmem-layout
 container

The nvmem devices description works like this:

* Most cases (EEPROM & co):

eeprom@x {
	 compatible = "<eeprom-compatible>";
	 ...
};

* MTD case:

flash@y {
	compatible = "<flash-compatible>";
	...
	otp {
		compatible = "user-otp"; /* or "factory-otp" */
		...
	};
};

In the former case, the nvmem device is "eeprom@x", while in the latter
case the nvmem device is "otp".

Nvmem devices can produce nvmem cells. The current way to describe nvmem
cells is to locate them by providing their static byte and bit offset
and length. These information are stored in subnodes of the nvmem
device.

It is now a fact that such description does not fit more advanced use
cases where the location or the size of the cells may vary. There are
currently three known situations which require being described
differently: Kontron's SL28 VPD, ONIE's TLV table and U-Boot's
environment variables.

Hence, we need a way to describe the parsers that must be used in order
to make the dynamic discovery of the nvmem cells. This new description
must fit both use cases (the generic situation and the MTD case).

Let's create in both cases a container node named nvmem-layout whose
content will depend on the parser. Right now nvmem-layout.yaml is
"empty", but references to additional layout parser bindings will be
inserted in the near future. The final goal being something that looks
like:

* Most cases (EEPROM & co):

eeprom@x {
	compatible = "<eeprom-compatible>";
	...
	nvmem-layout {
		compatible = "<parser-compatible>";
		...
	};
};

* MTD case:

flash@y {
	compatible = "<flash-compatible>";
	...
	otp {
		compatible = "user-otp"; /* or "factory-otp" */
		...
		nvmem-layout {
			compatible = "<parser-compatible>";
			...
		};
	};
};

EEPROMs can be nvmem providers. Let's make all EEPROM bindings
reference nvmem.yaml as they should, so that nvmem cells and layout
parsers can be safely described within the EEPROM nodes.

Subject: [PATCH 0783/1480] slimbus: qcom-ngd-ctrl: drop PM runtime counter on
 transfer error paths

If transfer in qcom_slim_ngd_xfer_msg_sync() fails, we need to drop the
PM runtime usage counter to have it balanced.

-SLIM(Serial Low Power Interchip Media Bus) bus
-
-SLIMbus is a 2-wire bus, and is used to communicate with peripheral
-components like audio-codec.
-
-Required property for SLIMbus controller node:
-- compatible	- name of SLIMbus controller
-
-Child nodes:
-Every SLIMbus controller node can contain zero or more child nodes
-representing slave devices on the bus. Every SLIMbus slave device is
-uniquely determined by the enumeration address containing 4 fields:
-Manufacturer ID, Product code, Device index, and Instance value for
-the device.
-If child node is not present and it is instantiated after device
-discovery (slave device reporting itself present).
-
-In some cases it may be necessary to describe non-probeable device
-details such as non-standard ways of powering up a device. In
-such cases, child nodes for those devices will be present as
-slaves of the SLIMbus controller, as detailed below.
-
-Required property for SLIMbus child node if it is present:
-- reg		- Should be ('Device index', 'Instance ID') from SLIMbus
-		  Enumeration  Address.
-		  Device Index Uniquely identifies multiple Devices within
-		  a single Component.
-		  Instance ID Is for the cases where multiple Devices of the
-		  same type or Class are attached to the bus.
-
-- compatible	-"slimMID,PID". The textual representation of Manufacturer ID,
-	 	  Product Code, shall be in lower case hexadecimal with leading
-		  zeroes suppressed
-
-Optional property for SLIMbus child node if it is present:
-- slim-ifc-dev	- Should be phandle to SLIMBus Interface device.
-		  Required for devices which deal with streams.
-
-SLIMbus example for Qualcomm's slimbus manager component:
-
-	slim@28080000 {
-		compatible = "qcom,apq8064-slim", "qcom,slim";
-		reg = <0x28080000 0x2000>,

Subject: [PATCH 0794/1480] Accessiblity: speakup_soft: specifying the default
 driver parameters among the module params

This is an enhancement which allows to specify the default driver
parameters among the module parameters.

Adding default variables to the speakup_soft module
allows to easily set that at boot, rather than
setting the sys variables after boot.
More details can be found here:

Subject: [PATCH 0795/1480] Accessiblity: speakup_apollo: specifying the

This is an enhancement which allows to specify the default driver
parameters among the module parameters.

Adding default variables to the speakup_apollo module
allows to easily set that at boot, rather than
setting the sys variables after boot.

Subject: [PATCH 0803/1480] Accessiblity: speakup_keypc: specifying the default
 driver parameters among the module params

This is an enhancement which allows to specify the default driver
parameters among the module parameters.

Adding default variables to the speakup_keypc module
allows to easily set that at boot, rather than
setting the sys variables after boot.

Subject: [PATCH 0808/1480] Accessiblity: speakup_acntsa: specifying the
 default driver parameters among the module params

This is an enhancement which allows to specify the default driver
parameters among the module parameters.

Adding default variables to the speakup_acntsa module
allows to easily set that at boot, rather than
setting the sys variables after boot.
More details can be found here:

Subject: [PATCH 0810/1480] accessibility: speakup: phonetic spelling while
 arrowing letter by letter

This patch includes an enhancement requested frequently on the mailing
list.[1][2] It adds a variable, cur_phonetic in the spk_vars, which can
be set as a module parameter, as well as in /sys/speakup/cur_phonetic.
This patch also documents cur_phonetic as a sysfs attribute in
sysfs-driver-speakup.

When cur_phonetic=1, it causes speakup to speak letters phonetically if
paused on the character while arrowing through a word.

When a user does not set cur_phonetic to any value, the default value
for it would be 0.

 ocxl_file_register_afu()

If device_register() returns error in ocxl_file_register_afu(),
the name allocated by dev_set_name() need be freed. As comment
of device_register() says, it should use put_device() to give
up the reference in the error path. So fix this by calling
put_device(), then the name can be freed in kobject_cleanup(),
and info is freed in info_release().

Subject: [PATCH 0813/1480] ocxl: fix pci device refcount leak when calling
 get_function_0()

get_function_0() calls pci_get_domain_bus_and_slot(), as comment
says, it returns a pci device with refcount increment, so after
using it, pci_dev_put() needs be called.

Get the device reference when get_function_0() is not called, so
pci_dev_put() can be called in the error path and callers
unconditionally. And add comment above get_dvsec_vendor0() to tell
callers to call pci_dev_put().

Subject: [PATCH 0815/1480] virt: acrn: Mark the uuid field as unused

After the commits for userspace (see Link tags below) the uuid field
is not being used in the ACRN code. Update kernel to reflect these
changes, i.e. do the following:
- adding a comment explaining that it's not used anymore
- replacing the specific type by a raw buffer
- updating the example code accordingly

The advertised field confused users and actually never been used.
So the wrong part here is that kernel puts something which userspace
never used and hence this may confuse a reader of this code.

Note, that there is only a single tool that had been prepared a year
ago for these forthcoming changes in the kernel.

In some bad situation, the gts may be freed gru_check_chiplet_assignment.
The call chain can be gru_unload_context->gru_free_gru_context->gts_drop
and kfree finally. However, the caller didn't know if the gts is freed
or not and use it afterwards. This will trigger a Use after Free bug.

Fix it by introducing a return value to see if it's in error path or not.
Free the gts in caller if gru_check_chiplet_assignment check failed.

 .probe_new()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

The probe function doesn't make use of the i2c_device_id * parameter so it
can be trivially converted.

Subject: [PATCH 0832/1480] char: misc: Increase the maximum number of dynamic
 misc devices to 1048448

On AmpereOne, 128 dynamic misc devices is not enough for the per-cpu
coresight_tmc devices.  Switch the dynamic minors allocator to an ida and
add logic to allocate in the ranges [0..127] and [256..1048575], leaving
[128..255] for static misc devices.  Dynamic allocations start from 127
growing downwards and then increasing from 256, so device numbering for the
first 128 devices remain the same as before.

As comment of device_register() says, it should use put_device() to give

Subject: [PATCH 0836/1480] cacheinfo: Remove of_node_put() for fw_token

fw_token is used for DT/ACPI systems to identify CPUs sharing caches.
For DT based systems, fw_token is set to a pointer to a DT node.

commit 3da72e18371c ("cacheinfo: Decrement refcount in
cache_setup_of_node()")
doesn't increment the refcount of fw_token anymore in
cache_setup_of_node(). fw_token is indeed used as a token and not
as a (struct device_node*), so no reference to fw_token should be
kept.

However, [1] is triggered when hotplugging a CPU multiple times
since cache_shared_cpu_map_remove() decrements the refcount to
fw_token at each CPU unplugging, eventually reaching 0.

Remove of_node_put() for fw_token in cache_shared_cpu_map_remove().

[1]

Subject: [PATCH 0837/1480] iio: adc: ad_sigma_delta: do not use internal
 iio_dev lock
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Drop 'mlock' usage by making use of iio_device_claim_direct_mode().
This change actually makes sure we cannot do a single conversion while
buffering is enable. Note there was a potential race in the previous
code since we were only acquiring the lock after checking if the bus is
enabled.

Subject: [PATCH 0839/1480] iio: temperature: mlx90632 Add runtime
 powermanagement modes

The sensor can operate in lower power modes and even make measurements when
in those lower powered modes. The decision was taken that if measurement
is not requested within 2 seconds the sensor will remain in SLEEP_STEP
power mode, where measurements are triggered on request with setting the
start of measurement bit (SOB). In this mode the measurements are taking
a bit longer because we need to start it and complete it. Currently, in
continuous mode we read ready data and this mode is activated if sensor
measurement is requested within 2 seconds. The suspend timeout is
increased to 6 seconds (instead of 3 before), because that enables more
measurements in lower power mode (SLEEP_STEP), with the lowest refresh
rate (2 seconds).

From 4e6151403631255828a5530d9d6233caedcd2976 Mon Sep 17 00:00:00 2001
From: Crt Mori <cmo@melexis.com>
Date: Thu, 22 Sep 2022 10:13:24 +0200
Subject: [PATCH 0841/1480] iio: temperature: mlx90632 Change return value of
 sensor measurement channel

The current EINVAL value is more applicable to embedded library, where
user can actually put the fixed value to the sensor. In case of the
driver if the value of the channel is invalid it is better in inform
userspace that Channel was out of range as that implies more to internal
driver error than invalid input. It also makes for easier debugging of
where the error comes from during the development.

Subject: [PATCH 0843/1480] iio: filter: admv8818: close potential
 out-of-bounds read in __admv8818_read_[h|l]pf_freq()

ADMV8818_SW_IN_WR0_MSK and ADMV8818_SW_OUT_WR0_MSK have 3 bits,
which means a length of 8, but freq_range_hpf and freq_range_lpf
array size is 4, may end up reading 4 elements beyond the end of
those arrays.

Check value first before access freq_range_hpf and freq_range_lpf
to harden against the hardware allowing out of range values.

Subject: [PATCH 0844/1480] iio: light: vcnl4000: Preserve conf bits when
 toggle power
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As the vcnl4040 and vcnl4200 chip uses runtime power management for
turning the ambient light and proximity sensors on/off, it overwrites
the entire register each time. In ALS_CONF register bit fields ALS_IT,
ALS_PERS, ALS_INT_EN are overwritten. In PS_CONF1 register bit fields
PS_DUTY, PS_PERS, PS_IT, PS_HD, and PS_INT are overwritten.

Add functions for preserving the affected bit fields when changing power
state.

Subject: [PATCH 0846/1480] iio: multiplexer: Switch to use dev_err_probe()
 helper

In the probe path, dev_err() can be replaced with dev_err_probe()
which will check if error code is -EPROBE_DEFER and prints the
error name. It also sets the defer probe reason which can be
checked later through debugfs. It's more simple in error path.

Subject: [PATCH 0847/1480] iio: adc: ti-ads131e08: Silence no spi_device_id
 warnings

SPI devices use the spi_device_id for module autoloading even on
systems using device tree, after commit 5fa6863ba692 ("spi: Check
we have a spi_device_id for each DT compatible"), kernel warns as
follows since the spi_device_id is missing:

SPI driver ads131e08 has no spi_device_id for ti,ads131e04
SPI driver ads131e08 has no spi_device_id for ti,ads131e06

Add spi_device_id entries to silence the warnings, and ensure driver

Subject: [PATCH 0848/1480] iio: accel: sca3300: Silence no spi_device_id
 warning

SPI devices use the spi_device_id for module autoloading even on
systems using device tree, after commit 5fa6863ba692 ("spi: Check
we have a spi_device_id for each DT compatible"), kernel warns as
follows since the spi_device_id is missing:

SPI driver sca3300 has no spi_device_id for murata,scl3300

Add spi_device_id entries to silence the warning, and ensure driver

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

'mlock' was being grabbed when setting the device frequency. In order to
not introduce any functional change a new lock is added. With that in
mind, the lock also needs to be grabbed in the places where 'mlock' is
since it was also being used to protect st->config against the current
device state.

On the other places the lock was being used, we can just drop
it since we are only doing one i2c bus read/write which is already
safe.

While at it, properly include "mutex.h" for mutex related APIs.

 lock
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The iio_device lock is only meant for internal use. Hence define a
device local lock to protect against concurrent accesses.

While at it, properly include "mutex.h" for mutex related APIs.

This is a precursor change to make it simpler to remove the 'mlock'
usage. Having the code in it's own helper function, also makes it easier
to read the error paths.

Subject: [PATCH 0861/1480] iio: adc: vf610_adc: vf610_adc: do not use internal
 iio_dev lock
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In order to drop the internal lock usage we needed two different things:

1) The first place where 'mlock' was being used was a typical case where
iio_device_claim_direct_mode() fits perfectly.
2) In the second case, it was being used to prevent concurrent accesses
to the device and shared data but nothing was being enforced with
regards to buffering (i.e, there was nothing preventing from changing
the conversion mode while buffering). Hence, in this case, a new lock
was introduced in the state structure.

Note that the goal is not to introduce any functional change and that is
the reason why a new lock was introduced to guarantee 2).

While at it, properly include "mutex.h" for mutex related APIs.

Subject: [PATCH 0874/1480] iio: adc: add max11410 adc driver

Adding support for max11410 24-bit, 1.9ksps delta-sigma adc which
has 3 differential reference and 10 differential channel inputs.
Inputs and references can be buffered internally. Inputs can also
be amplified with internal PGA.

Device has four digital filter modes: FIR50/60, FIR50, FIR60 and SINC4.
FIR 50Hz and 60Hz rejections can be enabled/disabled separately.
Digital filter selection affects sampling frequency range so driver
has to consider the configured filter when configuring sampling frequency.

From: Olivier Moysan <olivier.moysan@foss.st.com>
Date: Wed, 12 Oct 2022 16:21:59 +0200
Subject: [PATCH 0879/1480] dt-bindings: iio: adc: stm32-adc: add stm32mp13
 compatibles

Add st,stm32mp13-adc-core and st,stm32mp13-adc compatibles
to support STM32MPU13 SoC.

On STM32MP13x, each ADC peripheral has a single ADC block.
These ADC peripherals, ADC1 and ADC2, are fully independent.

Main characteristics of STM32MP13x ADC:
- One interrupt line per ADC
- 6 to 12 bits resolution
- 19 channels

ADC2 instance supports two extra internal channels VDDCPU and VDDQ_DDR.
Add "vddcpu" and "vddq_ddr" internal channels names to the reserved
labels list.

From cf0fb80ae1675179620d964d629b43ca57219ced Mon Sep 17 00:00:00 2001
From: Olivier Moysan <olivier.moysan@foss.st.com>
Date: Wed, 12 Oct 2022 16:22:00 +0200
Subject: [PATCH 0880/1480] iio: adc: stm32-adc: add stm32mp13 support

Add STM32 ADC support for STM32MP13x SOCs family.

On STM32MP13x, each ADC peripheral has a single ADC block.
These ADC peripherals, ADC1 and ADC2, are fully independent.
This introduces changes in common registers handling.

Some features such as boost mode, channel preselection and
linear calibration are not supported by the STM32MP13x ADC.
Add diversity management for these features.

The STM32MP13x ADC introduces registers and bitfield variants
on existing features such as calibration factors and internal
channels. Add register diversity management.

Add also support for new internal channels VDDCPU and VDDQ_DDR.

Subject: [PATCH 0882/1480] iio: core: introduce
 iio_device_{claim|release}_buffer_mode() APIs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

These APIs are analogous to iio_device_claim_direct_mode() and
iio_device_release_direct_mode() but, as the name suggests, with the
logic flipped. While this looks odd enough, it will have at least two
users (in following changes) and it will be important to move the IIO
mlock to the private struct.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The pattern used in this device does not quite fit in the
iio_device_claim_direct_mode() typical usage. In this case,
iio_buffer_enabled() was being used not to prevent the raw
access but to allow it. Hence, let's make use of the new
iio_device_claim_buffer_mode() API to make sure we stay in
buffered mode during the complete read.

Note that we are shadowing the error code returned by
iio_device_claim_buffer_mode() so that we keep the original one
(-EAGAIN). The reason is that some userspace stack might already be
relying on this particular code so that we are not taking chances and
leave it alone.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The pattern used in this device does not quite fit in the
iio_device_claim_direct_mode() typical usage. In this case, we want to
know if we are in buffered mode or not to know if the device is powered
(buffer mode) or not. And depending on that max30102_get_temp() will
power on the device if needed. Hence, in order to keep the same
functionality, we try to:

1. Claim Buffered mode;
2: If 1) succeeds call max30102_get_temp() without powering on the
   device;
3: Release Buffered mode;
4: If 1) fails, Claim Direct mode;
5: If 4) succeeds call max30102_get_temp() with powering on the device;
6: Release Direct mode;
7: If 4) fails, goto to 1) and try again.

This dance between buffered and direct mode is not particularly pretty
(as well as the loop introduced by the goto statement) but it does allow
us to get rid of the mlock usage while keeping the same behavior.

Subject: [PATCH 0885/1480] iio: core: move 'mlock' to 'struct iio_dev_opaque'
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Now that there are no more users accessing 'mlock' directly, we can move
it to the iio_dev private structure. Hence, it's now explicit that new
driver's should not directly use this lock.

Subject: [PATCH 0886/1480] iio: pressure: mpl115: Implementing low power mode
 by shutdown gpio

MPL115 supports shutdown gpio which can be used to set the state
to low power mode. Power from all internal circuits and
registers is removed. This is done by pulling the SHDN pin to low.
This patch enables runtime PM on MPL115 to increase power savings.

According to spec., a wakeup time period of ~5 ms exists between
waking up and actually communicating with the device. This is
implemented using sleep delay.

Dropped Rui's tag on basis this is rather different from v1 due to
the different macro implementation.

Subject: [PATCH 0889/1480] iio: imu: inv_icm42600: Move exports to
 IIO_ICM42600 namespace

As these exports are only relevant to core module and users in the
bus specific modules, move them out of the main kernel namespace.

Includes using EXPORT_NS_GPL_DEV_PM_OPS() and the simplifications that
brings by allowing the compiler to remove unused struct dev_pm_ops
and callbacks without needing explicit __maybe_unused markings.

Subject: [PATCH 0894/1480] iio: imu: st_lsm6dsx: Simplify using
 devm_regulator_*get_enable()

Use devm_regulator_bulk_get_enable() instead of open coded bulk-get,
bulk-enable, add-action-to-disable-at-detach - pattern.

A functional change (which seems like a bugfix) is that if
regulator_bulk_get fails, the enable is not attempted.

This simplifies code and makes it less tempting to add manual control

Whilst here also switch to dev_err_probe() to provide more information
if a deferred probe occurs.

+ *
+ * The ODR divider is not explicitly specified, but it can be deduced based

+ *
+ * For example, for Sinc4+Sinc1, max ODR is 218.18. That means that the

+ * mode.
+ *
+ * The formulas for converting between ODR and FS for a specific filter
+ * mode can be deduced from the same table.
+ *
+ * Notice that FS = 1 actually means max ODR, and that ODR decreases by
+ * (maximum ODR / maximum FS) for each increment of FS.
+ *
+ * odr = MAX_ODR / odr_div * (1 - (fs - 1) / fs_max) <=>
+ * odr = MAX_ODR * (1 - (fs - 1) / fs_max) / odr_div <=>
+ * odr = MAX_ODR * (1 - (fs - 1) / fs_max) / odr_div <=>
+ * odr = MAX_ODR * (fs_max - fs + 1) / (fs_max * odr_div)
+ * (used in ad4130_fs_to_freq)
+ *
+ * For the opposite formula, FS can be extracted from the last one.
+ *
+ * MAX_ODR * (fs_max - fs + 1) = fs_max * odr_div * odr <=>
+ * fs_max - fs + 1 = fs_max * odr_div * odr / MAX_ODR <=>

These drivers only turns the power on at probe and off via a custom
devm_add_action_or_reset() callback. The two regulators were handled
separately so also switch to bulk registration.
The new devm_regulator_bulk_get_enable() replaces all this boilerplate
code.

Content-Transfer-Encoding: 8bit

This driver only turns the power on at probe and off via a custom
devm_add_action_or_reset() callback. The new devm_regulator_get_enable()
replaces this boilerplate code.

Note that in event of an error on the devm_regulator_get() the driver
would have continued without enabling the regulator which is probably
not a good idea.  So here we handle any error as a reason to fail the
probe(). In theory this may expose breakage on a platform that was
previously papered over but it seems low risk.

The probe function doesn't make use of the i2c_device_id * parameter so it
can be trivially converted.

Subject: [PATCH 0931/1480] dt-bindings: iio: Add KX022A accelerometer

KX022A is a 3-axis Accelerometer from ROHM/Kionix. The sensor features
include variable ODRs, I2C and SPI control, FIFO/LIFO with watermark IRQ,
tap/motion detection, wake-up & back-to-sleep events, four acceleration
ranges (2, 4, 8 and 16g) and probably some other cool features.

Add the basic device tree description for the accelerometer. Only basic
accelerometer features are considered as of now - new properties may or
may not be needed in the future when rest of the features are supported.

 accelerometer

KX022A is a 3-axis accelerometer from ROHM/Kionix. The sensor features

tap/motion detection, wake-up & back-to-sleep events, four acceleration
ranges (2, 4, 8 and 16g), and probably some other cool features.

Add support for the basic accelerometer features such as getting the
acceleration data via IIO. (raw reads, triggered buffer [data-ready] or
using the WMI IRQ).

Important things to be added include the double-tap, motion
detection and wake-up as well as the runtime power management.

Subject: [PATCH 0935/1480] iio: Add IIO_STATIC_CONST_DEVICE_ATTR

Add IIO_STATIC_CONST_DEVICE_ATTR macro for creating an read-only
iio_dev_attr which returns constant value. This macro is intended to be
used when replacing the IIO_CONST_ATTR - attributes for triggered
buffers because the triggered buffer attributes must be of type
iio_dev_attr.

Subject: [PATCH 0940/1480] iio: Don't silently expect attribute types

The iio_triggered_buffer_setup_ext() and the
devm_iio_kfifo_buffer_setup_ext() were changed by
commit 15097c7a1adc ("iio: buffer: wrap all buffer attributes into iio_dev_attr")
to silently expect that all attributes given in buffer_attrs array are
device-attributes. This expectation was not forced by the API - and some
drivers did register attributes created by IIO_CONST_ATTR().

When using IIO_CONST_ATTRs the added attribute "wrapping" does not copy
the pointer to stored string constant and when the sysfs file is read the
kernel will access to invalid location.

Change the function signatures to expect an array of iio_dev_attrs to
avoid similar errors in the future.

Merge conflict resolved whilst applying due to patch crossing with
two new drivers (kx022a accelerometer and ad4130 ADC).

There are lots of uses of this in probe() and we are about to introduce
some more, so add a local variable to simplify this.

Subject: [PATCH 0944/1480] iio: adc: cc10001: Use devm_ to call device power
 down.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

It is presumably safe to call the powerdown whether or not we are
in the commented shared state (the driver always did this).

The power down was previously out of order wrt to the probe() function
so move using devm_ will ensure it occurs after the userspace interfaces
are removed.

Subject: [PATCH 0945/1480] iio: adc: cc10001: Switch remaining IIO calls in
 probe to devm_ forms.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As everything else is now handled by devm managed releases the
triggered buffer setup and IIO device registration can also be
moved over to their devm forms allowing dropping of remove().

Only user of drvdata associated with the struct device was the
remove function, so also drop the platform_set_drvdata() call.

Subject: [PATCH 0948/1480] iio: imu: st_lsm6dsx: introduce sw trigger support

There are some hw configuration where irq0 and/or irq1 pins are not
connected to the SPI or I2C/I3C controller. In order to avoid polling
the output register introduce iio-sw trigger support when irq line is
not available (or hw FIFO is not supported).

Subject: [PATCH 0954/1480] Documentation: ad4130: format list of
 in_voltage-voltage_filter_mode_available modes

Sphinx reports two warnings on sysfs documentation for AD4130 driver:

Documentation/ABI/testing/sysfs-bus-iio-adc-ad4130:2: WARNING: Unexpected indentation.
Documentation/ABI/testing/sysfs-bus-iio-adc-ad4130:2: WARNING: Block quote ends without a blank line; unexpected unindent.

These are due to misformatting of sinc* modes list. Format it with bullet
list. Since each entry spans multiple lines, separate each with a blank
line.

Subject: [PATCH 0957/1480] dt-bindings: iio: temperature: ltc2983: use hex for
 sensor address

Addresses should be in hex, fix it.

Although the driver initially specified 1-20, it can be made free-range
since the address is supposed to match reg, onto which we can impose
restrictions based on the compatible property value.

Give a little bit of information on what each item in the matrix is
supposed to be.

Also, some matrices put the 'minItems' and 'maxItems' keywords in the
wrong level. They should be on the same level as the 'items' keyword.
Fix it.

Subject: [PATCH 0967/1480] iio: temperature: ltc2983: support more parts

Add support for the following parts:
 * LTC2984
 * LTC2986
 * LTM2985

The LTC2984 is a variant of the LTC2983 with EEPROM.
The LTC2986 is a variant of the LTC2983 with only 10 channels,
EEPROM and support for active analog temperature sensors.
The LTM2985 is software-compatible with the LTC2986.

From
https://treexy.com/products/driver-fusion/database/sensors/semtech/sx9360-proximity/

sx9360 SAR sensor can be presented with ACPI ID SAMM0208.

Whilst this does not appear to be an official ACPI ID, it is in the wild
(perhaps due to a typo on the SAM PnP ID).

Subject: [PATCH 0972/1480] dt-bindings: iio: imu: st_lsm6dsx: add lsm6dsv16x

Add device bindings for lsm6dsv16x IMU sensor.
Use lsm6dsv as fallback device for lsm6dsv16x since it implements all the
features currently supported by lsm6dsv16x.

The probe function doesn't make use of the i2c_device_id * parameter so it
can be trivially converted.

The probe function doesn't make use of the i2c_device_id * parameter so it
can be trivially converted.

Subject: [PATCH 1127/1480] iio: adc: max11410: fix incomplete vref buffer mask

VREFP bit was missing from channel configuration mask and VREFN bit was
included twice instead which fails to enable positive reference buffer when
requested by a channel. Channels that don't enable vrefp buffer were not
affected.

Fixes: a44ef7c46097 ("iio: adc: add max11410 adc driver")

Subject: [PATCH 1128/1480] iio: adis: add '__adis_enable_irq()' implementation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add '__adis_enable_irq()' implementation which is the unlocked
version of 'adis_enable_irq()'.
Call '__adis_enable_irq()' instead of 'adis_enable_irq()' from
'__adis_intial_startup()' to keep the expected unlocked functionality.

This fix is needed to remove a deadlock for all devices which are
using 'adis_initial_startup()'. The deadlock occurs because the
same mutex is acquired twice, without releasing it.
The mutex is acquired once inside 'adis_initial_startup()', before
calling '__adis_initial_startup()', and once inside
'adis_enable_irq()', which is called by '__adis_initial_startup()'.
The deadlock is removed by calling '__adis_enable_irq()', instead of
'adis_enable_irq()' from within '__adis_initial_startup()'.

Subject: [PATCH 1138/1480] iio: addac: ad74413r: fix integer promotion bug in
 ad74413_get_input_current_offset()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The constant AD74413R_ADC_RESULT_MAX is defined via GENMASK, so its
type is "unsigned long".

Hence in the expression voltage_offset * AD74413R_ADC_RESULT_MAX,
voltage_offset is first promoted to unsigned long, and since it may be
negative, that results in a garbage value. For example, when range is
AD74413R_ADC_RANGE_5V_BI_DIR, voltage_offset is -2500 and
voltage_range is 5000, so the RHS of this assignment is, depending on
sizeof(long), either 826225UL or 3689348814709142UL, which after
truncation to int then results in either 826225 or 1972216214 being
the output from in_currentX_offset.

Casting to int avoids that promotion and results in the correct -32767
output.

Subject: [PATCH 1146/1480] iio: addac: ad74413r: add support for reset-gpio

We have a board where the reset pin of the ad74412 is connected to a
gpio, but also pulled low (i.e., asserted) by default. Hence to get
the chip out of reset, the driver needs to know about that gpio and
deassert the reset signal before attempting to communicate with the
chip.

When a reset-gpio is given in device tree, use that instead of the
software reset. According to the data sheet, the two methods are
functionally equivalent.

Subject: [PATCH 1147/1480] iio: adc: stm32-adc: smart calibration support

Add smart calibration support for STM32MP1.
- STM32MP15x: both linear & offset calibration are supported
- STM32MP13x: Only offset calibration is supported

Linear calibration:
Linear calibration is SoC dependent and does not change over time
so it can be done only once.
Linear calibration may have already been done in u-boot.
Skip calibration execution if calibration data are already available.
Save calibration factors in private data and restore them from private
data on next ADC start.

Offset calibration:
This calibration may vary over time, depending on temperature or voltage.
Run offset single-ended and differential calibration on each ADC start,
as it is not time consuming. This calibration do not need to be saved.
So, remove calfact_s and calfact_d value and bitfields that are no
longer used.

Subject: [PATCH 1150/1480] iio: adc128s052: add proper .data members in
 adc128_of_match table

Prior to commit bd5d54e4d49d ("iio: adc128s052: add ACPI _HID
AANT1280"), the driver unconditionally used spi_get_device_id() to get
the index into the adc128_config array.

However, with that commit, OF-based boards now incorrectly treat all
supported sensors as if they are an adc128s052, because all the .data
members of the adc128_of_match table are implicitly 0. Our board,
which has an adc122s021, thus exposes 8 channels whereas it really
only has two.

Subject: [PATCH 1151/1480] dt-bindings: iio: adc: renesas,rzg2l-adc: Document
 RZ/Five SoC

The ADC block on the RZ/Five SoC is identical to one found on the RZ/G2UL
SoC. "renesas,r9a07g043-adc" compatible string will be used on the RZ/Five
SoC so to make this clear, update the comment to include RZ/Five SoC.

No driver changes are required as generic compatible string
"renesas,rzg2l-adc" will be used as a fallback on RZ/Five SoC.

dt-schema has been modified to handle it as a standard unit, but the

-nanoamp properties with a $ref.
Remove this since it's the only occurrence left.

Subject: [PATCH 1157/1480] tracing: Add __cpumask to denote a trace event
 field that is a cpumask_t

The trace events have a __bitmask field that can be used for anything
that requires bitmasks. Although currently it is only used for CPU
masks, it could be used in the future for any type of bitmasks.

There is some user space tooling that wants to know if a field is a CPU
mask and not just some random unsigned long bitmask. Introduce
"__cpumask()" helper functions that work the same as the current
__bitmask() helpers but displays in the format file:

  field:__data_loc cpumask_t *[] mask;    offset:36;      size:4; signed:0;

Instead of:

  field:__data_loc unsigned long[] mask;  offset:32;      size:4; signed:0;

The main difference is the type. Instead of "unsigned long" it is
"cpumask_t *". Note, this type field needs to be a real type in the
__dynamic_array() logic that both __cpumask and__bitmask use, but the
comparison field requires it to be a scalar type whereas cpumask_t is a
structure (non-scalar). But everything works when making it a pointer.

Valentin added changes to remove the need of passing in "nr_bits" and the
__cpumask will always use nr_cpumask_bits as its size.

Subject: [PATCH 1158/1480] tracing: Add trace_trigger kernel command line
 option

Allow triggers to be enabled at kernel boot up. For example:

  trace_trigger="sched_switch.stacktrace if prev_state == 2"

The above will enable the stacktrace trigger on top of the sched_switch
event and only trigger if its prev_state is 2 (TASK_UNINTERRUPTIBLE). Then
at boot up, a stacktrace will trigger and be recorded in the tracing ring
buffer every time the sched_switch happens where the previous state is
TASK_INTERRUPTIBLE.

Another useful trigger would be "traceoff" which can stop tracing on an
event if a field of the event matches a certain value defined by the
filter ("if" statement).

Subject: [PATCH 1159/1480] ring_buffer: Remove unused "event" parameter

After commit a389d86f7fd0 ("ring-buffer: Have nested events still record
running time stamp"), the "event" parameter is no longer used in either
ring_buffer_unlock_commit() or rb_commit(). Best to remove it.

Subject: [PATCH 1160/1480] tracing/osnoise: Add osnoise/options file

Add the tracing/osnoise/options file to control
osnoise/timerlat tracer features. It is a single
file to contain multiple features, similar to
the sched/features file.

Reading the file displays a list of options. Writing
the OPTION_NAME enables it, writing NO_OPTION_NAME disables
it.

The DEAFULTS is a particular option that resets the options
to the default ones.

It uses a bitmask to keep track of the status of the option. When
needed, we can add a list of static keys, but for now
it does not justify the memory increase.

Subject: [PATCH 1161/1480] tracing/osnoise: Add OSNOISE_WORKLOAD option

The osnoise tracer is not only a tracer, and a set of tracepoints,
but also a workload dispatcher.

In preparation for having other workloads, e.g., in user-space,
add an option to avoid dispatching the workload.

By not dispatching the workload, the osnoise: tracepoints become
generic events to measure the execution time of *any* task on Linux.

For example:

  # cd /sys/kernel/tracing/
  # cat osnoise/options
  DEFAULTS OSNOISE_WORKLOAD
  # echo NO_OSNOISE_WORKLOAD > osnoise/options
  # cat osnoise/options
  NO_DEFAULTS NO_OSNOISE_WORKLOAD
  # echo osnoise > set_event
  # echo osnoise > current_tracer
  # tail -8 trace

Subject: [PATCH 1165/1480] tracing: Optimize event type allocation with IDA
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After commit 060fa5c83e67 ("tracing/events: reuse trace event ids after
 overflow"), trace events with dynamic type are linked up in list
'ftrace_event_list' through field 'trace_event.list'. Then when max
event type number used up, it's possible to reuse type number of some
freed one by traversing 'ftrace_event_list'.

As instead, using IDA to manage available type numbers can make codes
simpler and then the field 'trace_event.list' can be dropped.

Since 'struct trace_event' is used in static tracepoints, drop
'trace_event.list' can make vmlinux smaller. Local test with about 2000
tracepoints, vmlinux reduced about 64KB:
  before：-rwxrwxr-x 1 root root 76669448 Nov  8 17:14 vmlinux
  after： -rwxrwxr-x 1 root root 76604176 Nov  8 17:15 vmlinux

Subject: [PATCH 1166/1480] ftrace: Avoid needless updates of the ftrace
 function call

Song Shuai reported:

    The list func (ftrace_ops_list_func) will be patched first
    before the transition between old and new calls are set,
    which fixed the race described in this commit `59338f75`.

    While ftrace_trace_function changes from the list func to a
    ftrace_ops func, like unregistering the klp_ops to leave the only
    global_ops in ftrace_ops_list, the ftrace_[regs]_call will be
    replaced with the list func although it already exists. So there
    should be a condition to avoid this.

And suggested using another variable to keep track of what the ftrace
function is set to. But this could be simplified by using a helper
function that does the same with a static variable.

It matches to the prefix (interval timestamp), so better to have them together.
No functional change intended.

Subject: [PATCH 1169/1480] perf stat: Do not align time prefix in CSV output

We don't care about the alignment in the CSV output as it's intended for machine
processing.  Let's get rid of it to make the output more compact.

Subject: [PATCH 1171/1480] perf stat: Remove prefix argument in
 print_metric_headers()

It always passes a whitespace to the function, thus we can just add it to the
function body.  Furthermore, it's only used in the normal output mode.

Well, actually CSV used it but it doesn't need to since we don't care about the
indentation or alignment in the CSV output.

It already passes the stat_config argument, then it can find the value in the
config.  No need to pass it separately.

Subject: [PATCH 1175/1480] perf stat: Pass 'struct outstate' to

It passes prefix and cgroup pointers but the outstate already has them.
Let's pass the outstate pointer instead.

Subject: [PATCH 1176/1480] perf stat: Pass struct outstate to printout()

The printout() takes a lot of arguments and sets an outstate with the
value.  Instead, we can fill the outstate first and then pass it to
reduce the number of arguments.

Subject: [PATCH 1177/1480] perf stat: Do not pass runtime_stat to printout()

It always passes a pointer to rt_stat as it's the only one.  Let's not
pass it and directly refer it in the printout().

Subject: [PATCH 1178/1480] perf stat: Pass through 'struct outstate'

Now most of the print functions take a pointer to the struct outstate.
We have one in the evlist__print_counters() and pass it through the
child functions.

Subject: [PATCH 1179/1480] perf stat: Fix JSON output in metric-only mode

It generated a broken JSON output when aggregation mode or cgroup is
used with --metric-only option.  Also get rid of the header line and
make the output single line for each entry.

It needs to know whether the current metric is the first one or not.
So add 'first' field in the outstate and mark it false after printing.

Before:

  # perf stat -a -j --metric-only true
  {"unit" : "GHz"}{"unit" : "insn per cycle"}{"unit" : "branch-misses of all branches"}
  {{"metric-value" : "0.797"}{"metric-value" : "1.65"}{"metric-value" : "0.89"}
   ^

  # perf stat -a -j --metric-only --per-socket true
  {"unit" : "GHz"}{"unit" : "insn per cycle"}{"unit" : "branch-misses of all branches"}
  {"socket" : "S0", "aggregate-number" : 8, {"metric-value" : "0.295"}{"metric-value" : "1.88"}{"metric-value" : "0.64"}
                                           ^

After:

  # perf stat -a -j --metric-only true
  {"GHz" : "0.990", "insn per cycle" : "2.06", "branch-misses of all branches" : "0.59"}

  # perf stat -a -j --metric-only --per-socket true
  {"socket" : "S0", "aggregate-number" : 8, "GHz" : "0.439", "insn per cycle" : "2.14", "branch-misses of all branches" : "0.51"}

Subject: [PATCH 1180/1480] perf stat: Rename "aggregate-number" to "cpu-count"
 in JSON

As the JSON output has been broken for a little while, I guess there are
not many users.  Let's rename the field to more intuitive one. :)

Subject: [PATCH 1181/1480] perf stat: Tidy up JSON metric-only output when no
 metrics

It printed empty strings for each metric.  I guess it's needed for CSV
output to match the column number.  We could just ignore the empty
metrics in JSON but it ended up with a broken JSON object with a
trailing comma.

So I added a dummy '"metric-value" : "none"' part.  To do that, it
needs to pass struct outstate to print_metric_end() to check if any
metric value is printed or not.

Before:

  # perf stat -aj --metric-only --per-socket --for-each-cgroup system.slice true
  {"socket" : "S0", "cpu-count" : 8, "cgroup" : "system.slice", "" : "", "" : "", "" : "", "" : "", "" : "", "" : "", "" : "", "" : ""}

After:

  # perf stat -aj --metric-only --per-socket --for-each-cgroup system.slice true
  {"socket" : "S0", "cpu-count" : 8, "cgroup" : "system.slice", "metric-value" : "none"}

Alderlake-N only has E-core, it has been moved to non-hybrid code path on
the kernel side, so add the cpuid for Alderlake-N separately.

Add core event list for Alderlake-N, it is based on the
ADL gracemont v1.16 JSON file.

Subject: [PATCH 1186/1480] perf symbol: correction while adjusting symbol

perf doesn't provide proper symbol information for specially crafted
.debug files.

Sometimes .debug file may not have similar program header as runtime
ELF file. For example if we generate .debug file using objcopy
--only-keep-debug resulting file will not contain .text, .data and
other runtime sections. That means corresponding program headers will
have zero FileSiz and modified Offset.

Example: program header of text section of libxxx.so:

Type           Offset             VirtAddr           PhysAddr
               FileSiz            MemSiz              Flags  Align
LOAD        0x00000000003d3000 0x00000000003d3000 0x00000000003d3000
            0x000000000055ae80 0x000000000055ae80  R E    0x1000

Same program header after executing:
objcopy --only-keep-debug libxxx.so libxxx.so.debug

LOAD        0x0000000000001000 0x00000000003d3000 0x00000000003d3000
            0x0000000000000000 0x000000000055ae80  R E    0x1000

Offset and FileSiz have been changed.

Following formula will not provide correct value, if program header
taken from .debug file (syms_ss):

    sym.st_value -= phdr.p_vaddr - phdr.p_offset;

Correct program header information is located inside runtime ELF
file (runtime_ss).

Subject: [PATCH 1188/1480] perf list: JSON escape encoding improvements

Use strbuf to make the string under construction's length unlimited. Use
the format %s to mean a literal string copy and %S to signify a need to
escape the string. Add supported for escaping a newline character.

From 23680f0b7d7f67a935adb38058110d2d81bbe6ea Mon Sep 17 00:00:00 2001
From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Date: Wed, 23 Nov 2022 13:25:19 +0100
Subject: [PATCH 1190/1480] driver core: make struct class.dev_uevent() take a
 const *

The dev_uevent() in struct class should not be modifying the device that
is passed into it, so mark it as a const * and propagate the function
signature changes out into all relevant subsystems that use this
callback.

From ff62b8e6588fb07bedda7423622c140c4edd66a7 Mon Sep 17 00:00:00 2001
From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Date: Wed, 23 Nov 2022 13:25:20 +0100
Subject: [PATCH 1191/1480] driver core: make struct class.devnode() take a
 const *
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The devnode() in struct class should not be modifying the device that is
passed into it, so mark it as a const * and propagate the function
signature changes out into all relevant subsystems that use this
callback.

Subject: [PATCH 1192/1480] iio: imu: st_lsm6dsx: add support to ISM330IS

Add support to STM ISM330IS (accelerometer and gyroscope) Mems sensor.
The ISM330IS sensor can use LSM6DSO16IS as fallback device since it
implements all the ISM330IS features currently implemented in
st_lsm6dsx.

Move the lookup of the munmap request to the fastrpc_req_munmap and pass
on only the buf to the lower level fastrpc_req_munmap_impl. That way
we can use the lower level fastrpc_req_munmap_impl on error path in
fastrpc_req_mmap to free the buf without searching for the munmap
request it belongs to.

Subject: [PATCH 1203/1480] misc: fastrpc: Add support for audiopd

In order to be able to start the adsp listener for audiopd using adsprpcd,
we need to add the corresponding ioctl for creating a static process.
On that ioctl call we need to allocate the heap. Allocating the heap needs
to be happening only once and needs to be kept between different device
open calls, so attach it to the channel context to make sure that remains
until the RPMSG driver is removed. Then, if there are any VMIDs associated
with the static ADSP process, do a call to SCM to assign it.
And then, send all the necessary info related to heap to the DSP.

Subject: [PATCH 1204/1480] misc: fastrpc: Safekeep mmaps on interrupted invoke

If the userspace daemon is killed in the middle of an invoke (e.g.
audiopd listerner invoke), we need to skip the unmapping on device
release, otherwise the DSP will crash. So lets safekeep all the maps
only if there is in invoke interrupted, by attaching them to the channel
context (which is resident until RPMSG driver is removed), and free them
on RPMSG driver remove.

Subject: [PATCH 1207/1480] counter: stm32-lptimer-cnt: fix the check on arr
 and cmp registers update

The ARR (auto reload register) and CMP (compare) registers are
successively written. The status bits to check the update of these
registers are polled together with regmap_read_poll_timeout().
The condition to end the loop may become true, even if one of the register
isn't correctly updated.
So ensure both status bits are set before clearing them.

Subject: [PATCH 1210/1480] coresight: cti: Fix null pointer error on CTI init
 before ETM

When CTI is discovered first then the function
coresight_set_assoc_ectdev_mutex() is called to set the association
between CTI and ETM device. Recent lockdep fix passes a null pointer.

This patch passes the correct pointer.

Before patch: log of boot oops sequence with CTI discovered first:

Subject: [PATCH 1215/1480] usb: typec: ucsi: Resume in separate work

It can take more than one second to check each connector
when the system is resumed. So if you have, say, eight
connectors, it may take eight seconds for ucsi_resume() to
finish. That's a bit too much.

This will modify ucsi_resume() so that it schedules a work
where the interface is actually resumed instead of checking
the connectors directly. The connections will also be
checked in separate tasks which are queued for each connector
separately.

Subject: [PATCH 1220/1480] usb: add usb_set_intfdata() documentation

USB drivers do not need to call usb_set_intfdata(intf, NULL) in their
usb_driver::disconnect callback because the core already does it in [1].

However, this fact is widely unknown, c.f.:

  $ git grep "usb_set_intfdata(.*NULL)" | wc -l
  215

Especially, setting the interface to NULL before all action completed
can result in a NULL pointer dereference. Not calling
usb_set_intfdata() at all in disconnect() is the safest method.

Add documentation to usb_set_intfdata() to clarify this point.

Also remove the call in usb-skeletion's disconnect() not to confuse
the new comers.

Subject: [PATCH 1222/1480] usb: typec: Add partner PD object wrapper

Some port drivers may want to set a Type-C partner as a parent for a
USB Power Delivery object, but the Type-C partner struct isn't exposed
outside of the Type-C class driver. Add a wrapper to
usb_power_delivery_register() which sets the provided Type-C partner
as a parent to the USB PD object. This helps to avoid exposing the
Type-C partner's device struct unnecessarily.

Subject: [PATCH 1225/1480] usb: cdnsp: fix lack of ZLP for ep0

Patch implements the handling of ZLP for control transfer.
To send the ZLP driver must prepare the extra TRB in TD with
length set to zero and TRB type to TRB_NORMAL.
The first TRB must have set TRB_CHAIN flag, TD_SIZE = 1
and TRB type to TRB_DATA.

Subject: [PATCH 1226/1480] usb: misc: onboard_usb_hub: Drop obsolete
 dependency on COMPILE_TEST

Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.

It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.

Subject: [PATCH 1228/1480] usb: gadget: f_hid: fix f_hidg lifetime vs cdev

The embedded struct cdev does not have its lifetime correctly tied to
the enclosing struct f_hidg, so there is a use-after-free if /dev/hidgN
is held open while the gadget is deleted.

This can readily be replicated with libusbgx's example programs (for
conciseness - operating directly via configfs is equivalent):

	gadget-hid
	exec 3<> /dev/hidg0
	gadget-vid-pid-remove
	exec 3<&-

Pull the existing device up in to struct f_hidg and make use of the
cdev_device_{add,del}() helpers.  This changes the lifetime of the
device object to match struct f_hidg, but note that it is still added
and deleted at the same time.

 hidg_alloc

Unify error handling at the end of the function, reducing the risk of
missing something on one of the error paths.

Moving the increment of opts->refcnt later means there is no need to
decrement it on the error path and is safe as this is guarded by
opts->lock which is held for this entire section.

Subject: [PATCH 1235/1480] driver core: fix up some missing class.devnode()
 conversions.

In commit ff62b8e6588f ("driver core: make struct class.devnode() take a
const *") the ->devnode callback changed the pointer to be const, but a
few instances of PowerPC drivers were not caught for some reason.

Fix this up by changing the pointers to be const.

Subject: [PATCH 1236/1480] usb: dwc3: Fix race between dwc3_set_mode and
 __dwc3_set_mode

dwc->desired_dr_role is changed by dwc3_set_mode inside a spinlock but
then read by __dwc3_set_mode outside of that lock. This can lead to a
race condition when very quick successive role switch events happen:

CPU A
	dwc3_set_mode(DWC3_GCTL_PRTCAP_HOST) // first role switch event
		spin_lock_irqsave(&dwc->lock, flags);
		dwc->desired_dr_role = mode; // DWC3_GCTL_PRTCAP_HOST
		spin_unlock_irqrestore(&dwc->lock, flags);
		queue_work(system_freezable_wq, &dwc->drd_work);

CPU B
	__dwc3_set_mode
		// ....
		spin_lock_irqsave(&dwc->lock, flags);
		// desired_dr_role is DWC3_GCTL_PRTCAP_HOST
		dwc3_set_prtcap(dwc, dwc->desired_dr_role);
		spin_unlock_irqrestore(&dwc->lock, flags);

CPU A
	dwc3_set_mode(DWC3_GCTL_PRTCAP_DEVICE) // second event
		spin_lock_irqsave(&dwc->lock, flags);
		dwc->desired_dr_role = mode; // DWC3_GCTL_PRTCAP_DEVICE
		spin_unlock_irqrestore(&dwc->lock, flags);

CPU B (continues running __dwc3_set_mode)
	switch (dwc->desired_dr_role) { // DWC3_GCTL_PRTCAP_DEVICE
	// ....
	case DWC3_GCTL_PRTCAP_DEVICE:
		// ....
		ret = dwc3_gadget_init(dwc);

We then have DWC3_GCTL.DWC3_GCTL_PRTCAPDIR = DWC3_GCTL_PRTCAP_HOST and
dwc->current_dr_role = DWC3_GCTL_PRTCAP_HOST but initialized the
controller in device mode. It's also possible to get into a state
where both host and device are intialized at the same time.
Fix this race by creating a local copy of desired_dr_role inside
__dwc3_set_mode while holding dwc->lock.

Subject: [PATCH 1237/1480] USB: serial: cp210x: add support for B0 hangup

A request to set the line speed to B0 is used to hang up a modem
connection by deasserting the modem control lines.

Note that there is no need reconfigure the line speed in hardware when
B0 is requested (even if some drivers do set it to an arbitrary value
for implementation or protocol reasons).

Subject: [PATCH 1242/1480] xhci: print warning when HCE was set

When HCE(Host Controller Error) is set, it means that the xhci hardware
controller has an error at this time, but the current xhci driver
software does not log this event.

By adding an HCE event detection in the xhci interrupt processing
interface, a warning log is output to the system, which is convenient
for system device status tracking.

Subject: [PATCH 1243/1480] xhci: Apply XHCI_RESET_TO_DEFAULT quirk to ADL-N

ADL-N systems have the same issue as ADL-P, where a large boot firmware
delay is seen if USB ports are left in U3 at shutdown. So apply the
XHCI_RESET_TO_DEFAULT quirk to ADL-N as well.

This patch depends on commit 34cd2db408d5 ("xhci: Add quirk to reset
host back to default state at shutdown").

The issue it fixes is a ~20s boot time delay when booting from S5. It
affects ADL-N devices, and ADL-N support was added starting from v5.16.

Subject: [PATCH 1244/1480] xhci: export two xhci_hub functions for xhci-pci
 module usage

some Intel Alder Lake xHC hosts on ChromeOS platforms need special
workarounds touching port registers at xHC pci host hibernate.

Export xhci_port_state_to_neutral() and xhci_find_slot_id_by_port()
so they can be called from xhci-pci.c and thus the xhci-pci module.

Subject: [PATCH 1245/1480] xhci: disable U3 suspended ports in S4 hibernate
 poweroff_late stage

Disable U3 suspended ports in hibernate S4 poweroff_late for systems
with XHCI_RESET_TO_DEFAULT quirk, if wakeup is not enabled.

This reduces the number of self-powered usb devices from surviving in
U3 suspended state into next reboot.

Bootloader/firmware on these systems can't handle usb ports in U3, and
will timeout, causing extra delay during reboot/restore from S4.

Add pci_poweroff_late() callback to struct usb_hcd to get this done at
the correct stage in hibernate.

Subject: [PATCH 1246/1480] xhci: Prevent infinite loop in transaction errors
 recovery for streams

Make sure to also limit the amount of soft reset retries for transaction
errors on streams in cases where the transaction error event doesn't point
to any specific TRB.

In these cases we don't know the TRB or stream ring, but we do know which
endpoint had the error.

To keep error counting simple and functional, move the current err_count
from ring structure to endpoint structure.

When the requested line speed is B0 (hangup) there is no need to use the
current speed in the line-coding request. This specifically avoids
requesting a zero DTE rate when the current speed is B0, which could
potentially confuse buggy firmware.

Subject: [PATCH 1259/1480] vfio/iova_bitmap: refactor iova_bitmap_set() to
 better handle page boundaries

Commit f38044e5ef58 ("vfio/iova_bitmap: Fix PAGE_SIZE unaligned bitmaps")
had fixed the unaligned bitmaps by capping the remaining iterable set at
the start of the bitmap. Although, that mistakenly worked around
iova_bitmap_set() incorrectly setting bits across page boundary.

Fix this by reworking the loop inside iova_bitmap_set() to iterate over a
range of bits to set (cur_bit .. last_bit) which may span different pinned
pages, thus updating @page_idx and @offset as it sets the bits. The
previous cap to the first page is now adjusted to be always accounted
rather than when there's only a non-zero pgoff.

While at it, make @page_idx , @offset and @nbits to be unsigned int given
that it won't be more than 512 and 4096 respectively (even a bigger
PAGE_SIZE or a smaller struct page size won't make this bigger than the
above 32-bit max). Also, delete the stale kdoc on Return type.

Subject: [PATCH 1260/1480] extcon: max77843: Replace irqchip mask_invert with
 unmask_base

Remove use of the deprecated mask_invert flag. Inverted mask
registers (where a '1' bit enables an IRQ) can be described more
directly as an unmask register.

 for I2C Master Hub variant

The I2C Master Hub is a stripped down version of the GENI Serial Engine
QUP Wrapper Controller but only supporting I2C serial engines without
DMA support.

Those I2C serial engines variants have some requirements:
- a separate "core" clock
- doesn't support DMA, thus no memory interconnect path
- fixed FIFO size not discoverable in the HW_PARAM_0 register

Add a desc struct specifying all those requirements which will be used in
a next change when adding the I2C Master Hub serial engine compatible.

Subject: [PATCH 1272/1480] drivers/i2c: use simple i2c probe

All these drivers have an i2c probe function which doesn't use the
"struct i2c_device_id *id" parameter, so they can trivially be
converted to the "probe_new" style of probe with a single argument.

This is part of an ongoing transition to single-argument i2c probe
functions. Old-style probe functions involve a call to i2c_match_id:
in drivers/i2c/i2c-core-base.c,

         /*
          * When there are no more users of probe(),
          * rename probe_new to probe.
          */
         if (driver->probe_new)
                 status = driver->probe_new(client);
         else if (driver->probe)
                 status = driver->probe(client,
                                        i2c_match_id(driver->id_table, client));
         else
                 status = -EINVAL;

Drivers which don't need the second parameter can be declared using
probe_new instead, avoiding the call to i2c_match_id. Drivers which do
can still be converted to probe_new-style, calling i2c_match_id
themselves (as is done currently for of_match_id).

This change was done using the following Coccinelle script, and fixed
up for whitespace changes:

 rtllib_rx_Monitor()

The skb is delivered to netif_rx() in rtllib_monitor_rx(), which may free it,
after calling this, dereferencing skb may trigger use-after-free.

Subject: [PATCH 1285/1480] staging: r8188eu: fix the number of probereq
 retries

issue_probereq_ex sends a probe request and retries if this fails. There's
no point in making the number of retries configurable. Hard-code the value
that's used by issue_probereq_ex's only caller.

Simplify the code to check the loop condition only once.

Define a struct ieee80211_mgmt in the OnBeacon function. Use it to replace
one GetAddr3Ptr call. This is a tiny step towards making GetAddr3Ptr
obsolete.

Subject: [PATCH 1294/1480] staging: r8188eu: pass only ies to
 process_p2p_ps_ie

The process_p2p_ps_ie function parses the information elements of a beacon
message and extracts p2p-related info.

process_p2p_ps_ie does not receive a pointer to the information elements
as one would expect. Instead it receives a pointer to the timestamp field
in the beacon message. process_p2p_ps_ie increments this pointer by
_BEACON_IE_OFFSET_ to jump to the start of the information elements (and
decreases the buffer length accordingly).

This is clumsy and hard to understand. Rewrite this such that
process_p2p_ps_ie takes a pointer to the information elements and the
total length of all elements. Check up-front that the total length is
not negative.

Subject: [PATCH 1296/1480] staging: r8188eu: simplify update_sta_support_rate
 params

The update_sta_support_rate function takes a pointer to information
elements and the total length of all these elements. Use our variables
for pointer and length instead of calculating them manually.

Subject: [PATCH 1297/1480] staging: r8188eu: exit if beacon is not from our
 bss

Do not process an incoming beacon message in the OnBeacon function if the
beacon was sent by a base station other than the one to which we're
connected.

This patch does not modify the behaviour of the code. It reverts the if
condition and returns if the beacon should not be processed. This is
simpler than wrapping the entire processing into a large if clause.

Subject: [PATCH 1298/1480] staging: r8188eu: stop beacon processing if kmalloc
 fails

If we cannot allocate a struct wlan_bssid_ex in the OnBeacon function, we
should stop processing the incoming beacon message and return.

For kmalloc failures, the current code just skips the update of network
and beacon info and tries to continue with the authentication. The update
would set the encryption algorithm that should be used for the
authentication.

Subject: [PATCH 1299/1480] staging: r8188eu: simplify error handling for
 missing station

Simplify the code to handle the case where we're associated to a station
that is not in our list of known stations.

We can simply exit in this case. This patch reverts the if-condition and
saves one level of indentation.

 helpers

Use the dedicated non-atomic helpers for {clear,set}_bit() and their
test variants, i.e. the double-underscore versions.  Depsite being
defined in atomic.h, and despite the kernel versions being atomic in the
kernel, tools' {clear,set}_bit() helpers aren't actually atomic.  Move
to the double-underscore versions so that the versions that are expected
to be atomic (for kernel developers) can be made atomic without
affecting users that don't want atomic operations.

No functional change intended.

Subject: [PATCH 1302/1480] staging: r8188eu: use ieee80211_mgmt to parse
 addresses

Define a struct ieee80211_mgmt in the OnDisassoc function and use it to
parse the addresses in the incoming disassoc message. This replaces some
driver-specific functions for address parsing.

Use the struct ieee80211_mgmt to read the reason code instead of parsing
the message manually.

Remove the pframe pointer, it's no longer used.

Subject: [PATCH 1304/1480] staging: r8188eu: move bBusyTraffic update

Move the update of bBusyTraffic into the else branch. The if branch ends
with a return statement, so bBusyTraffic will not be updated in this case.

With this change in place, we can reorder the code and save some levels of
indentation.

The OnDisassoc function hasn't got much to do if we're not working as an
access point. Move this case out of the large if statement to simplify the
code.

If we receive a disassoc message from an unknown station, we can drop this
message immediately. Reorder the code to make this clearer.

Subject: [PATCH 1307/1480] perf branch: Fix interpretation of branch records

Commit 93315e46b000fc80 ("perf/core: Add speculation info to branch
entries") added a new field in between type and new_type. Perf has its
own copy of this struct so update it to match the kernel side.

This doesn't currently cause any issues because new_type is only used by
the Arm BRBE driver which isn't merged yet.

Committer notes:

Is this really an ABI? How are we supposed to deal with old perf.data
files with new tools and vice versa? :-\

Subject: [PATCH 1308/1480] perf arm64: Fix mksyscalltbl, don't lose syscalls
 due to sort -nu

When using "sort -nu", arm64 syscalls were lost.  That is, the io_setup
syscall (number 0) and all but one (typically ftruncate; 64) of the
syscalls that are defined symbolically (like "#define __NR_ftruncate
__NR3264_ftruncate") at the point where "sort" is applied.

This creation-of-syscalls.c-scheme is, judging from comments,
copy-pasted from powerpc, and worked there because at the time, its
tools/arch/powerpc/include/uapi/asm/unistd.h had *literals*, like
"#define __NR_ftruncate 93".

With sort being numeric and the non-numeric key effectively evaluating
to 0, the sort option "-u" means these "duplicates" are removed.
There's no need to remove syscall lines with duplicate numbers for arm64
because there are none, so let's fix that by just losing the "-u".
Having the table numerically sorted on syscall-number for the rest of
the syscalls looks nice, so keep the "-n".

This reverts commit c4b41b83c25073c09bfcc4e5ec496c9dd316656b.

As Ian said, the "cpu-count" is not appropriate for uncore events, also it
caused a perf test failure.

Subject: [PATCH 1313/1480] staging: r8188eu: use subtype helper in
 rtw_check_bcn_info

Use ieee80211_is_beacon to check the frame subtype in rtw_check_bcn_info.
Replace the call to the driver-specific GetFrameSubType function.

 vfio_pci_core.ko

The vfio_spapr_pci_eeh_open/release() functions are one line wrappers
around an arch function. Just call them directly. This eliminates some
weird exported symbols that don't need to exist.

Subject: [PATCH 1317/1480] vfio/spapr: Move VFIO_CHECK_EXTENSION into

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The PPC64 kconfig is a bit of a rats nest, but it turns out that if
CONFIG_SPAPR_TCE_IOMMU is on then EEH must be too:

config SPAPR_TCE_IOMMU
	bool "sPAPR TCE IOMMU Support"
	depends on PPC_POWERNV || PPC_PSERIES
	select IOMMU_API
	help
	  Enables bits of IOMMU API required by VFIO. The iommu_ops
	  is not implemented as it is not necessary for VFIO.

config PPC_POWERNV
	select FORCE_PCI

config PPC_PSERIES
	select FORCE_PCI

config EEH
	bool
	depends on (PPC_POWERNV || PPC_PSERIES) && PCI
	default y

So, just open code the call to eeh_enabled() into tce_iommu_ioctl().

From e276e25819b8a173a21947720bb0a548c0b724b7 Mon Sep 17 00:00:00 2001
From: Jason Gunthorpe <jgg@nvidia.com>
Date: Mon, 5 Dec 2022 11:29:18 -0400
Subject: [PATCH 1318/1480] vfio: Move vfio_spapr_iommu_eeh_ioctl into
 vfio_iommu_spapr_tce.c

As with the previous patch EEH is always enabled if SPAPR_TCE_IOMMU, so
move this last bit of code into the main module.

Now that this function only processes VFIO_EEH_PE_OP remove a level of
indenting as well, it is only called by a case statement that already
checked VFIO_EEH_PE_OP.

This eliminates an unnecessary module and SPAPR code in a global header.

Subject: [PATCH 1320/1480] vfio: Fold vfio_virqfd.ko into vfio.ko

This is only 1.8k, putting it in its own module is not really
necessary. The kconfig infrastructure is still there to completely remove
it for systems that are trying for small footprint.

Put it in the main vfio.ko module now that kbuild can support multiple .c
files.

Subject: [PATCH 1321/1480] vfio/ap/ccw/samples: Fix device_register() unwind
 path

We always need to call put_device() if device_register() fails.
All vfio drivers calling device_register() include a similar unwind
stack via gotos, therefore split device_unregister() into its
device_del() and put_device() components in the unwind path, and
add a goto target to handle only the put_device() requirement.

Subject: [PATCH 1322/1480] container_of: add container_of_const() that
 preserves const-ness of the pointer

container_of does not preserve the const-ness of a pointer that is
passed into it, which can cause C code that passes in a const pointer to
get a pointer back that is not const and then scribble all over the data
in it.  To prevent this, container_of_const() will preserve the const
status of the pointer passed into it using the newly available _Generic()
method.

Subject: [PATCH 1325/1480] firmware_loader: fix up to_fw_sysfs() to preserve
 const

to_fw_sysfs() was changed in commit 23680f0b7d7f ("driver core: make
struct class.dev_uevent() take a const *") to pass in a const pointer
but not pass it back out to handle some changes in the driver core.
That isn't the best idea as it could cause problems if used incorrectly,
so switch to use the container_of_const() macro instead which will
preserve the const status of the pointer and enforce it by the compiler.

Subject: [PATCH 1327/1480] vfio: Extend the device migration protocol with
 PRE_COPY

The optional PRE_COPY states open the saving data transfer FD before
reaching STOP_COPY and allows the device to dirty track internal state
changes with the general idea to reduce the volume of data transferred
in the STOP_COPY stage.

While in PRE_COPY the device remains RUNNING, but the saving FD is open.

Only if the device also supports RUNNING_P2P can it support PRE_COPY_P2P,
which halts P2P transfers while continuing the saving FD.

PRE_COPY, with P2P support, requires the driver to implement 7 new arcs
and exists as an optional FSM branch between RUNNING and STOP_COPY:
    RUNNING -> PRE_COPY -> PRE_COPY_P2P -> STOP_COPY

A new ioctl VFIO_MIG_GET_PRECOPY_INFO is provided to allow userspace to
query the progress of the precopy operation in the driver with the idea it
will judge to move to STOP_COPY at least once the initial data set is
transferred, and possibly after the dirty size has shrunk appropriately.

This ioctl is valid only in PRE_COPY states and kernel driver should
return -EINVAL from any other migration state.

Compared to the v1 clarification, STOP_COPY -> PRE_COPY is blocked
and to be defined in future.
We also split the pending_bytes report into the initial and sustaining
values, e.g.: initial_bytes and dirty_bytes.
initial_bytes: Amount of initial precopy data.
dirty_bytes: Device state changes relative to data previously retrieved.
These fields are not required to have any bearing to STOP_COPY phase.

It is recommended to leave PRE_COPY for STOP_COPY only after the
initial_bytes field reaches zero. Leaving PRE_COPY earlier might make
things slower.

+ *
+ * This ioctl is valid only in PRE_COPY states and kernel driver should

+ *
+ * The vfio_precopy_info data structure returned by this ioctl provides
+ * estimates of data available from the device during the PRE_COPY states.
+ * This estimate is split into two categories, initial_bytes and
+ * dirty_bytes.
+ *
+ * The initial_bytes field indicates the amount of initial precopy
+ * data available from the device. This field should have a non-zero initial
+ * value and decrease as migration data is read from the device.
+ * It is recommended to leave PRE_COPY for STOP_COPY only after this field
+ * reaches zero. Leaving PRE_COPY earlier might make things slower.
+ *
+ * The dirty_bytes field tracks device state changes relative to data
+ * previously retrieved.  This field starts at zero and may increase as
+ * the internal device state is modified or decrease as that modified
+ * state is read from the device.
+ *
+ * Userspace may use the combination of these fields to estimate the
+ * potential data size available during the PRE_COPY phases, as well as
+ * trends relative to the rate the device is dirtying its internal
+ * state, but these fields are not required to have any bearing relative
+ * to the data size available during the STOP_COPY phase.
+ *
+ * Drivers have a lot of flexibility in when and what they transfer during the
+ * PRE_COPY phase, and how they report this from VFIO_MIG_GET_PRECOPY_INFO.
+ *
+ * During pre-copy the migration data FD has a temporary "end of stream" that is
+ * reached when both initial_bytes and dirty_byte are zero. For instance, this
+ * may indicate that the device is idle and not currently dirtying any internal
+ * state. When read() is done on this temporary end of stream the kernel driver
+ * should return ENOMSG from read(). Userspace can wait for more data (which may
+ * never come) by using poll.
+ *
+ * Once in STOP_COPY the migration data FD has a permanent end of stream
+ * signaled in the usual way by read() always returning 0 and poll always
+ * returning readable. ENOMSG may not be returned in STOP_COPY.

Subject: [PATCH 1328/1480] vfio/mlx5: Enforce a single SAVE command at a time

Enforce a single SAVE command at a time.

As the SAVE command is an asynchronous one, we must enforce running only
a single command at a time.

This will preserve ordering between multiple calls and protect from
races on the migration file data structure.

This is a must for the next patches from the series where as part of
PRE_COPY we may have multiple images to be saved and multiple SAVE
commands may be issued from different flows.

Subject: [PATCH 1329/1480] vfio/mlx5: Refactor PD usage

This patch refactors PD usage such as its life cycle will be as of the
migration file instead of allocating/destroying it upon each SAVE/LOAD
command.

This is a preparation step towards the PRE_COPY series where multiple
images will be SAVED/LOADED and a single PD can be simply reused.

From 91454f8b9bf4ce6be1d9a0b4de401bc3c6313a95 Mon Sep 17 00:00:00 2001
From: Yishai Hadas <yishaih@nvidia.com>
Date: Tue, 6 Dec 2022 10:34:29 +0200
Subject: [PATCH 1330/1480] vfio/mlx5: Refactor MKEY usage

This patch refactors MKEY usage such as its life cycle will be as of the
migration file instead of allocating/destroying it upon each
SAVE/LOAD command.

This is a preparation step towards the PRE_COPY series where multiple
images will be SAVED/LOADED.

We achieve it by having a new struct named mlx5_vhca_data_buffer which
holds the mkey and its related stuff as of sg_append_table,
allocated_length, etc.

The above fields were taken out from the migration file main struct,
into mlx5_vhca_data_buffer dedicated struct with the proper helpers in
place.

For now we have a single mlx5_vhca_data_buffer per migration file.
However, in coming patches we'll have multiple of them to support
multiple images.

Subject: [PATCH 1331/1480] vfio/mlx5: Refactor migration file state

Refactor migration file state to be an emum which is mutual exclusive.

As of that dropped the 'disabled' state as 'error' is the same from
functional point of view.

Next patches from the series will extend this enum for other relevant
states.

Subject: [PATCH 1332/1480] vfio/mlx5: Refactor to use queue based data chunks

Refactor to use queue based data chunks on the migration file.

The SAVE command adds a chunk to the tail of the queue while the read()
API finds the required chunk and returns its data.

In case the queue is empty but the state of the migration file is
MLX5_MIGF_STATE_COMPLETE, read() may not be blocked but will return 0 to
indicate end of file.

This is a step towards maintaining multiple images and their meta data
(i.e. headers) on the migration file as part of next patches from the
series.

Note:
At that point, we still use a single chunk on the migration file but
becomes ready to support multiple.

From 3319d287f4c04b9deece8ea00e27a70bbe32941b Mon Sep 17 00:00:00 2001
From: Yishai Hadas <yishaih@nvidia.com>
Date: Tue, 6 Dec 2022 10:34:32 +0200
Subject: [PATCH 1333/1480] vfio/mlx5: Introduce device transitions of PRE_COPY

In order to support PRE_COPY, mlx5 driver is transferring multiple
states (images) of the device. e.g.: the source VF can save and transfer
multiple states, and the target VF will load them by that order.

The device is saving three kinds of states:
1) Initial state - when the device moves to PRE_COPY state.
2) Middle state - during PRE_COPY phase via VFIO_MIG_GET_PRECOPY_INFO.
   There can be multiple states of this type.
3) Final state - when the device moves to STOP_COPY state.

After moving to PRE_COPY state, user is holding the saving migf FD and
can use it. For example: user can start transferring data via read()
callback. Also, user can switch from PRE_COPY to STOP_COPY whenever he
sees it fits. This will invoke saving of final state.

This means that mlx5 VFIO device can be switched to STOP_COPY without
transferring any data in PRE_COPY state. Therefore, when the device
moves to STOP_COPY, mlx5 will store the final state on a dedicated queue
entry on the list.

Subject: [PATCH 1334/1480] vfio/mlx5: Introduce SW headers for migration
 states

As mentioned in the previous patches, mlx5 is transferring multiple
states when the PRE_COPY protocol is used. This states mechanism
requires the target VM to know the states' size in order to execute
multiple loads.  Therefore, add SW header, with the needed information,
for each saved state the source VM is transferring to the target VM.

This patch implements the source VM handling of the headers, following
patch will implement the target VM handling of the headers.

Subject: [PATCH 1335/1480] vfio/mlx5: Introduce vfio precopy ioctl
 implementation

vfio precopy ioctl returns an estimation of data available for
transferring from the device.

Whenever a user is using VFIO_MIG_GET_PRECOPY_INFO, track the current
state of the device, and if needed, append the dirty data to the
transfer FD data. This is done by saving a middle state.

As mlx5 runs the SAVE command asynchronously, make sure to query for
incremental data only once there is no active save command.
Running both in parallel, might end-up with a failure in the incremental
query command on un-tracked vhca.

Also, a middle state will be saved only after the previous state has
finished its SAVE command and has been fully transferred, this prevents
endless use resources.

Subject: [PATCH 1336/1480] vfio/mlx5: Consider temporary end of stream as part
 of PRE_COPY

During PRE_COPY the migration data FD may have a temporary "end of
stream" that is reached when the initial_bytes were read and no other
dirty data exists yet.

For instance, this may indicate that the device is idle and not
currently dirtying any internal state. When read() is done on this
temporary end of stream the kernel driver should return ENOMSG from
read(). Userspace can wait for more data or consider moving to
STOP_COPY.

To not block the user upon read() and let it get ENOMSG we add a new
state named MLX5_MIGF_STATE_PRE_COPY on the migration file.

In addition, we add the MLX5_MIGF_STATE_SAVE_LAST state to block the
read() once we call the last SAVE upon moving to STOP_COPY.

Any further error will be marked with MLX5_MIGF_STATE_ERROR and the user
won't be blocked.

Subject: [PATCH 1337/1480] vfio/mlx5: Introduce multiple loads

In order to support PRE_COPY, mlx5 driver transfers multiple states
(images) of the device. e.g.: the source VF can save and transfer
multiple states, and the target VF will load them by that order.

This patch implements the changes for the target VF to decompose the
header for each state and to write and load multiple states.

Date: Tue, 6 Dec 2022 10:34:37 +0200
Subject: [PATCH 1338/1480] vfio/mlx5: Fallback to STOP_COPY upon specific
 PRE_COPY error

Before a SAVE command is issued, a QUERY command is issued in order to
know the device data size.
In case PRE_COPY is used, the above commands are issued while the device
is running. Thus, it is possible that between the QUERY and the SAVE
commands the state of the device will be changed significantly and thus
the SAVE will fail.

Currently, if a SAVE command is failing, the driver will fail the
migration. In the above case, don't fail the migration, but don't allow
for new SAVEs to be executed while the device is in a RUNNING state.
Once the device will be moved to STOP_COPY, SAVE can be executed again
and the full device state will be read.

Subject: [PATCH 1342/1480] hisi_acc_vfio_pci: Move the dev compatibility tests
 for early check

Instead of waiting till data transfer is complete to perform dev
compatibility, do it as soon as we have enough data to perform the
check. This will be useful when we enable the support for PRE_COPY.

The clk_rate attribute is not generic device tree bindings for I2C

It can be managed by clock binding.

Support the driver to obtain clock information by clk_rate or
clock property. Find clock first, if not, fall back to clk_rate.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If for whatever reasons pm_runtime_resume_and_get() failed, .remove() is
exited early, the clock isn't freed and runtime PM state isn't reset.

The right thing to do however is to free all resources that don't need
HW access after a problem with runtime PM. Also issue a warning in that
case and return 0 to suppress a less helpful warning by the driver core.

-	  the first and last consoles (starting at 1) as driver parameters.
-
-	  For example, if the driver is compiled as a module:
-
-	     modprobe sisusbvga first=1 last=5
-
-	  If you use hotplug, add this to your modutils config files with
-	  the "options" keyword, such as eg.
-
-	     options sisusbvga first=1 last=5
-
-	  If the driver is compiled into the kernel image, the parameters
-	  must be given in the kernel command like, such as
-
-	     sisusbvga.first=1 sisusbvga.last=5

Subject: [PATCH 1350/1480] USB: sisusbvga: rename sisusb.c to sisusbvga.c

As it's the only source for the sisusbvga module, there is no need for a
2-steps build.

Subject: [PATCH 1351/1480] USB: sisusbvga: use module_usb_driver()

Now, that we only do usb_register() and usb_sisusb_exit() in
module_init() and module_exit() respectivelly, we can simply use
module_usb_driver().

I got the following report while doing fault injection test:

  OF: ERROR: memory leak, expected refcount 1 instead of 4,
  of_node_get()/of_node_put() unbalanced - destroy cset entry:

If wusb3801_hw_init() fails, fwnode_handle_put() needs be called to
avoid refcount leak.

Setup function uvc_function_setup permits control transfer

data stage handler for OUT transfer uses memcpy to copy req->actual

Subject: [PATCH 1356/1480] usb: musb: remove extra check in
 musb_gadget_vbus_draw

The checks for musb->xceiv and musb->xceiv->set_power duplicate those in
usb_phy_set_power(), so there is no need of them. Moreover, not calling
usb_phy_set_power() results in usb_phy_set_charger_current() not being
called, so current USB config max current is not propagated through USB
charger framework and charger drivers may try to draw more current than
allowed or possible.

Fix that by removing those extra checks and calling usb_phy_set_power()
directly.

Tested on Motorola Droid4 and Nokia N900

Subject: [PATCH 1357/1480] usb: gadget: udc: drop obsolete dependencies on
 COMPILE_TEST

Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.

It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.

Content-Transfer-Encoding: 8bit

In fotg210_udc_probe(), if devm_clk_get() or clk_prepare_enable()
fails, 'fotg210' will not be freed, which will lead to a memory leak.
Fix it by moving kfree() to a proper location.

In addition，we can use "return -ENOMEM" instead of "goto err"
to simplify the code.

Subject: [PATCH 1361/1480] dt-bindings: usb: Add binding for Genesys Logic
 GL850G hub controller

The Genesys Logic GL850G is a USB 2.0 Single TT hub controller that
features 4 downstream ports, an internal 5V-to-3.3V LDO regulator (can
be bypassed) and an external reset pin.

Add a device tree binding for its USB protocol part. The internal LDO is
not covered by this and can just be modelled as a fixed regulator.

 GL850G hub support

Genesys Logic GL850G is a 4-port USB 2.0 STT hub that has a reset pin to
toggle and a 3.3V core supply exported (although an integrated LDO is
available for powering it with 5V).

Add the support for this hub, for controlling the reset pin and the core
power supply.

Subject: [PATCH 1363/1480] usb: ulpi: defer ulpi_register on ulpi_read_id
 timeout

Since commit 0f0101719138 ("usb: dwc3: Don't switch OTG -> peripheral
if extcon is present") Dual Role support on Intel Merrifield platform
broke due to rearranging the call to dwc3_get_extcon().

It appears to be caused by ulpi_read_id() on the first test write failing
with -ETIMEDOUT. Currently ulpi_read_id() expects to discover the phy via
DT when the test write fails and returns 0 in that case, even if DT does not
provide the phy. As a result usb probe completes without phy.

Make ulpi_read_id() return -ETIMEDOUT to its user if the first test write
fails. The user should then handle it appropriately. A follow up patch
will make dwc3_core_init() set -EPROBE_DEFER in this case and bail out.

Subject: [PATCH 1364/1480] usb: dwc3: core: defer probe on ulpi_read_id
 timeout

Since commit 0f0101719138 ("usb: dwc3: Don't switch OTG -> peripheral
if extcon is present"), Dual Role support on Intel Merrifield platform
broke due to rearranging the call to dwc3_get_extcon().

It appears to be caused by ulpi_read_id() masking the timeout on the first
test write. In the past dwc3 probe continued by calling dwc3_core_soft_reset()
followed by dwc3_get_extcon() which happend to return -EPROBE_DEFER.
On deferred probe ulpi_read_id() finally succeeded. Due to above mentioned
rearranging -EPROBE_DEFER is not returned and probe completes without phy.

On Intel Merrifield the timeout on the first test write issue is reproducible
but it is difficult to find the root cause. Using a mainline kernel and
rootfs with buildroot ulpi_read_id() succeeds. As soon as adding
ftrace / bootconfig to find out why, ulpi_read_id() fails and we can't
analyze the flow. Using another rootfs ulpi_read_id() fails even without
adding ftrace. We suspect the issue is some kind of timing / race, but
merely retrying ulpi_read_id() does not resolve the issue.

As we now changed ulpi_read_id() to return -ETIMEDOUT in this case, we
need to handle the error by calling dwc3_core_soft_reset() and request
-EPROBE_DEFER. On deferred probe ulpi_read_id() is retried and succeeds.

CIFS does not use page private data that needs migration, so it can just
wire up filemap_migrate_folio.  This prepares for removing ->writepage,
which is used as a fallback if no migrate_folio method is set.

Subject: [PATCH 1372/1480] cifs: stop using generic_writepages

generic_writepages is just a wrapper that calls ->writepages on a range,
and thus in the way of eventually removing ->writepage.  Switch cifs
to just open code it in preparation of removing ->writepage.

[note: I suspect just integrating the small wsize case with the rest
 of the writeback code might be a better idea here, but that needs
 someone more familiar with the code]

->writepage is a very inefficient method to write back data, and only
used through write_cache_pages or a a fallback when no ->migrate_folio
method is present.  Now that cifs implements ->migrate_folio and
doesn't call generic_writepages, the writepage method can be removed.

Subject: [PATCH 1374/1480] cifs: skip alloc when request has no pages

When smb3_init_transform_rq() was being called with requests (@old_rq)
which had no pages, it was unnecessarily allocating a single page for
every request in @new_rq.

Fix this by skipping page array allocation when requests have no pages
(e.g. !smb_rqst::rq_npages).

Also get rid of deprecated kmap() and use kmap_local_page() instead
while we're at it.

Subject: [PATCH 1375/1480] usb: gadget: uvc: Rename bmInterfaceFlags ->
 bmInterlaceFlags

In the specification documents for the Uncompressed and MJPEG USB
Video Payloads, the field name is bmInterlaceFlags - it has been
misnamed within the kernel.

Although renaming the field does break the kernel's interface to
userspace it should be low-risk in this instance. The field is read
only and hardcoded to 0, so there was never any value in anyone
reading it. A search of the uvc-gadget application and all the
forks that I could find for it did not reveal any users either.

Subject: [PATCH 1378/1480] ftrace/x86: Add back ftrace_expected for ftrace bug
 reports

After someone reported a bug report with a failed modification due to the
expected value not matching what was found, it came to my attention that
the ftrace_expected is no longer set when that happens. This makes for
debugging the issue a bit more difficult.

Set ftrace_expected to the expected code before calling ftrace_bug, so
that it shows what was expected and why it failed.

Subject: [PATCH 1379/1480] tracing: Allow multiple hitcount values in
 histograms

The hitcount is treated specially in the histograms - since it's
always expected to be there regardless of whether the user specified
anything or not, it's always added as the first histogram value.

Currently the code doesn't allow it to be added more than once as a
value, which is inconsistent with all the other possible values.  It
would seem to be a pointless thing to want to do, but other features
being added such as percent and graph modifiers don't work properly
with the current hitcount restrictions.

Fix this by allowing multiple hitcounts to be added.

Add 'nohitcount' ('NOHC' for short) option for suppressing display of
the raw hitcount column in the histogram.
Note that you must specify at least one value except raw 'hitcount'
when you specify this nohitcount option.

Subject: [PATCH 1384/1480] trace/kprobe: remove duplicated calls of
 ring_buffer_event_data

Function __kprobe_trace_func calls ring_buffer_event_data to
get a ring buffer, however, it has been done in above call
trace_event_buffer_reserve. So does __kretprobe_trace_func.

This patch removes those duplicated calls.

Subject: [PATCH 1385/1480] tracing/probes: Handle system names with hyphens

When creating probe names, a check is done to make sure it matches basic C
standard variable naming standards. Basically, starts with alphabetic or
underline, and then the rest of the characters have alpha-numeric or
underline in them.

But system names do not have any true naming conventions, as they are
created by the TRACE_SYSTEM macro and nothing tests to see what they are.
The "xhci-hcd" trace events has a '-' in the system name. When trying to
attach a eprobe to one of these trace points, it fails because the system
name does not follow the variable naming convention because of the
hyphen, and the eprobe checks fail on this.

Allow hyphens in the system name so that eprobes can attach to the
"xhci-hcd" trace events.

Subject: [PATCH 1386/1480] tracing: Fix complicated dependency of
 CONFIG_TRACER_MAX_TRACE

Both CONFIG_OSNOISE_TRACER and CONFIG_HWLAT_TRACER partially enables the
CONFIG_TRACER_MAX_TRACE code, but that is complicated and has
introduced a bug; It declares tracing_max_lat_fops data structure outside
of #ifdefs, but since it is defined only when CONFIG_TRACER_MAX_TRACE=y
or CONFIG_HWLAT_TRACER=y, if only CONFIG_OSNOISE_TRACER=y, that
declaration comes to a definition(!).

To fix this issue, and do not repeat the similar problem, makes
CONFIG_OSNOISE_TRACER and CONFIG_HWLAT_TRACER enables the
CONFIG_TRACER_MAX_TRACE always. It has there benefits;
- Fix the tracing_max_lat_fops bug
- Simplify the #ifdefs
- CONFIG_TRACER_MAX_TRACE code is fully enabled, or not.

Subject: [PATCH 1387/1480] x86/mm/kmmio: Switch to arch_spin_lock()

The mmiotrace tracer is "special". The purpose is to help reverse engineer
binary drivers by removing the memory allocated by the driver and when the
driver goes to access it, a fault occurs, the mmiotracer will record what
the driver was doing and then do the work on its behalf by single stepping
through the process.

But to achieve this ability, it must do some special things. One is it
needs to grab a lock while in the breakpoint handler. This is considered
an NMI state, and then lockdep warns that the lock is being held in both
an NMI state (really a breakpoint handler) and also in normal context.

As the breakpoint/NMI state only happens when the driver is accessing
memory, there's no concern of a race condition against the setup and
tear-down of mmiotracer.

To make lockdep and mmiotrace work together, convert the locks used in the
breakpoint handler into arch_spin_lock().

Subject: [PATCH 1388/1480] x86/mm/kmmio: Use rcu_read_lock_sched_notrace()

The mmiotrace tracer is "special". The purpose is to help reverse engineer
binary drivers by removing the memory allocated by the driver and when the
driver goes to access it, a fault occurs, the mmiotracer will record what
the driver was doing and then do the work on its behalf by single stepping
through the process.

But to achieve this ability, it must do some special things. One is to
take the rcu_read_lock() when the fault occurs, and then release it in the
breakpoint that is single stepping. This makes lockdep unhappy, as it
changes the state of RCU from within an exception that is not contained in
that exception, and we get a nasty splat from lockdep.

Instead, switch to rcu_read_lock_sched_notrace() as the RCU sched variant
has the same grace period as normal RCU. This is basically the same as
rcu_read_lock() but does not make lockdep complain about it.

Note, the preempt_disable() is still needed as it uses preempt_enable_no_resched().

Subject: [PATCH 1390/1480] tracing/hist: Fix out-of-bound write on
 'action_data.var_ref_idx'

When generate a synthetic event with many params and then create a trace
action for it [1], kernel panic happened [2].

It is because that in trace_action_create() 'data->n_params' is up to
SYNTH_FIELDS_MAX (current value is 64), and array 'data->var_ref_idx'
keeps indices into array 'hist_data->var_refs' for each synthetic event
param, but the length of 'data->var_ref_idx' is TRACING_MAP_VARS_MAX
(current value is 16), so out-of-bound write happened when 'data->n_params'
more than 16. In this case, 'data->match_data.event' is overwritten and
eventually cause the panic.

To solve the issue, adjust the length of 'data->var_ref_idx' to be
SYNTH_FIELDS_MAX and add sanity checks to avoid out-of-bound write.

Subject: [PATCH 1392/1480] tracing/hist: Fix issue of losting command info in
 error_log

When input some constructed invalid 'trigger' command, command info
in 'error_log' are lost [1].

The root cause is that there is a path that event_hist_trigger_parse()
is recursely called once and 'last_cmd' which save origin command is
cleared, then later calling of hist_err() will no longer record origin
command info:

  event_hist_trigger_parse() {
    last_cmd_set()  // <1> 'last_cmd' save origin command here at first
    create_actions() {
      onmatch_create() {
        action_create() {
          trace_action_create() {
            trace_action_create_field_var() {
              create_field_var_hist() {
                event_hist_trigger_parse() {  // <2> recursely called once
                  hist_err_clear()  // <3> 'last_cmd' is cleared here
                }
                hist_err()  // <4> No longer find origin command!!!

Since 'glob' is empty string while running into the recurse call, we
can trickly check it and bypass the call of hist_err_clear() to solve it.

Subject: [PATCH 1393/1480] ring-buffer: Handle resize in early boot up

With the new command line option that allows trace event triggers to be
added at boot, the "snapshot" trigger will allocate the snapshot buffer
very early, when interrupts can not be enabled. Allocating the ring buffer
is not the problem, but it also resizes it, which is, as the resize code
does synchronization that can not be preformed at early boot.

To handle this, first change the raw_spin_lock_irq() in rb_insert_pages()
to raw_spin_lock_irqsave(), such that the unlocking of that spin lock will
not enable interrupts.

Next, where it calls schedule_work_on(), disable migration and check if
the CPU to update is the current CPU, and if so, perform the work
directly, otherwise re-enable migration and call the schedule_work_on() to
the CPU that is being updated. The rb_insert_pages() just needs to be run
on the CPU that it is updating, and does not need preemption nor
interrupts disabled when calling it.

Subject: [PATCH 1394/1480] tracing: remove unnecessary trace_trigger ifdef

The trace_trigger command line option introduced by
commit a01fdc897fa5 ("tracing: Add trace_trigger kernel command line option")
doesn't need to depend on the CONFIG_HIST_TRIGGERS kernel config option.

This code doesn't depend on the histogram code, and the run-time
selection of triggers is usable without CONFIG_HIST_TRIGGERS.

Subject: [PATCH 1398/1480] tracing/osnoise: Add PANIC_ON_STOP option

Often the latency observed in a CPU is not caused by the work being done
in the CPU itself, but by work done on another CPU that causes the
hardware to stall all CPUs. In this case, it is interesting to know
what is happening on ALL CPUs, and the best way to do this is via
crash dump analysis.

Add the PANIC_ON_STOP option to osnoise/timerlat tracers. The default
behavior is having this option off. When enabled by the user, the system
will panic after hitting a stop tracing condition.

This option was motivated by a real scenario that Juri Lelli and I
were debugging.

Subject: [PATCH 1399/1480] tracing/osnoise: Add preempt and/or irq disabled
 options

The osnoise workload runs with preemption and IRQs enabled in such
a way as to allow all sorts of noise to disturb osnoise's execution.
hwlat tracer has a similar workload but works with irq disabled,
allowing only NMIs and the hardware to generate noise.

While thinking about adding an options file to hwlat tracer to
allow the system to panic, and other features I was thinking
to add, like having a tracepoint at each noise detection, it
came to my mind that is easier to make osnoise and also do
hardware latency detection than making hwlat "feature compatible"
with osnoise.

Other points are:
 - osnoise already has an independent cpu file.
 - osnoise has a more intuitive interface, e.g., runtime/period vs.
   window/width (and people often need help remembering what it is).
 - osnoise: tracepoints
 - osnoise stop options
 - osnoise options file itself

Moreover, the user-space side (in rtla) is simplified by reusing the
existing osnoise code.

Finally, people have been asking me about using osnoise for hw latency
detection, and I have to explain that it was sufficient but not
necessary. These options make it sufficient and necessary.

Adding a Suggested-by Clark, as he often asked me about this
possibility.

Subject: [PATCH 1402/1480] exfat: hint the empty entry which at the end of
 cluster chain

After traversing all directory entries, hint the empty directory
entry no matter whether or not there are enough empty directory
entries.

After this commit, hint the empty directory entries like this:

1. Hint the deleted directory entries if enough;
2. Hint the deleted and unused directory entries which at the
   end of the cluster chain no matter whether enough or not(Add
   by this commit);
3. If no any empty directory entries, hint the empty directory
   entries in the new cluster(Add by this commit).

This avoids repeated traversal of directory entries, reduces CPU
usage, and improves the performance of creating files and
directories(especially on low-performance CPUs).

Test create 5000 files in a class 4 SD card on imx6q-sabrelite
with:

for ((i=0;i<5;i++)); do
   sync
   time (for ((j=1;j<=1000;j++)); do touch file$((i*1000+j)); done)
done

The more files, the more performance improvements.

Subject: [PATCH 1403/1480] exfat: reduce the size of exfat_entry_set_cache

In normal, there are 19 directory entries at most for a file or
a directory.
  - A file directory entry
  - A stream extension directory entry
  - 1~17 file name directory entry

So the directory entries are in 3 sectors at most, it is enough
for struct exfat_entry_set_cache to pre-allocate 3 bh.

This commit changes the size of struct exfat_entry_set_cache as:

                   Before   After
32-bit system      88       32    bytes
64-bit system      168      48    bytes

Subject: [PATCH 1404/1480] exfat: support dynamic allocate bh for
 exfat_entry_set_cache

In special cases, a file or a directory may occupied more than 19
directory entries, pre-allocating 3 bh is not enough. Such as
  - Support vendor secondary directory entry in the future.
  - Since file directory entry is damaged, the SecondaryCount
    field is bigger than 18.

So this commit supports dynamic allocation of bh.

Subject: [PATCH 1405/1480] exfat: move exfat_entry_set_cache from heap to
 stack

The size of struct exfat_entry_set_cache is only 56 bytes on
64-bit system, and allocating from stack is more efficient than
allocating from heap.

Subject: [PATCH 1406/1480] exfat: rename exfat_free_dentry_set() to
 exfat_put_dentry_set()

Since struct exfat_entry_set_cache is allocated from stack,
no need to free, so rename exfat_free_dentry_set() to
exfat_put_dentry_set(). After renaming, the new function pair
is exfat_get_dentry_set()/exfat_put_dentry_set().

Subject: [PATCH 1408/1480] exfat: remove call ilog2() from exfat_readdir()

There is no need to call ilog2() for the conversions between
cluster and dentry in exfat_readdir(), because these conversions
can be replaced with EXFAT_DEN_TO_CLU()/EXFAT_CLU_TO_DEN().

Code refinement, no functional changes.

Subject: [PATCH 1414/1480] x86/mm/kmmio: Remove redundant preempt_disable()

Now that kmmio uses rcu_read_lock_sched_notrace() there's no reason to
call preempt_disable() as the read_lock_sched_notrace() already does that
and is redundant.

This also removes the preempt_enable_no_resched() as the "no_resched()"
portion was bogus as there's no reason to do that.

Three mount options: "tcpnodelay" and "noautotune" and "noblocksend"
were not displayed when passed in on cifs/smb3 mounts (e.g. displayed
in /proc/mounts e.g.).  No change to defaults so these are not
displayed if not specified on mount.

This is because in scatterwalk_copychunks(), we attempted to write to
a buffer (@sign) that was allocated in the stack (vmalloc area) by
crypt_message() and thus accessing its remaining 8 (x2) bytes ended up
crossing a page boundary.

To simply fix it, we could just pass @sign kmalloc'd from
crypt_message() and then we're done.  Luckily, we don't seem to pass
any other vmalloc'd buffers in smb_rqst::rq_iov...

Instead, let's map the correct pages and offsets from vmalloc buffers
as well in cifs_sg_set_buf() and then avoiding such oopses.

Date: Mon, 12 Dec 2022 12:36:33 +0100
Subject: [PATCH 1420/1480] writeback: Add asserts for adding freed inode to
 lists

In the past we had several use-after-free issues with inodes getting
added to writeback lists after evict() removed them. These are painful
to debug so add some asserts to catch the problem earlier. The only
non-obvious change in the commit is that we need to tweak
redirty_tail_locked() to avoid triggering assertion in
inode_io_list_move_locked().

Subject: [PATCH 1425/1480] exfat: fix overflow in sector and cluster
 conversion

According to the exFAT specification, there are at most 2^32-11
clusters in a volume. so using 'int' is not enough for cluster
index, the return value type of exfat_sector_to_cluster() should
be 'unsigned int'.

Subject: [PATCH 1427/1480] tracing: Have trigger filter parsing errors show up
 in error_log

It is annoying that the filter parsing of triggers do not show up in the
error_log. Trying to figure out what is incorrect in the input is
difficult when it fails for a typo.

Have the errors of filter parsing show up in error_log as well.

Subject: [PATCH 1428/1480] tracing: Remove pointer (asterisk) and brackets
 from cpumask_t field

To differentiate between long arrays and cpumasks, the __cpumask() field
was created. Part of the TRACE_EVENT() macros test if the type is signed
or not by using the is_signed_type() macro. The __cpumask() field used the
__dynamic_array() helper but because cpumask_t is a structure, it could
not be used in the is_signed_type() macro as that would fail to build, so
instead it passed in the pointer to cpumask_t.

Unfortunately, that creates in the format file:

  field:__data_loc cpumask_t *[] mask;    offset:36;      size:4; signed:0;

Which looks like an array of pointers to cpumask_t and not a cpumask_t
type, which is misleading to user space parsers.

Douglas Raillard pointed out that the "[]" are also misleading, as
cpumask_t is not an array.

Since cpumask() hasn't been created yet, and the parsers currently fail on
it (but will still produce the raw output), make it be:

  field:__data_loc cpumask_t mask;    offset:36;      size:4; signed:0;

Which is the correct type of the field.

Then the parsers can be updated to handle this.

Subject: [PATCH 1430/1480] tracing: Do not synchronize freeing of trigger
 filter on boot up

If a trigger filter on the kernel command line fails to apply (due to
syntax error), it will be freed. The freeing will call
tracepoint_synchronize_unregister(), but this is not needed during early
boot up, and will even trigger a lockdep splat.

Avoid calling the synchronization function when system_state is
SYSTEM_BOOTING.

Subject: [PATCH 1433/1480] perf stat: Fix printing field separator in CSV
 metrics output

In 'perf stat' with CSV output option, number of fields in metrics
output is not matching with number of fields in other event output
lines.

Sample output below after applying patch to fix printing os->prefix.

	# ./perf stat -x, --per-socket -a -C 1 ls
	S0,1,82.11,msec,cpu-clock,82111626,100.00,1.000,CPUs utilized
	S0,1,2,,context-switches,82109314,100.00,24.358,/sec
	------
====>	S0,1,,,,,,,1.71,stalled cycles per insn

The above command line uses field separator as "," via "-x," option and
per-socket option displays socket value as first field. But here the
last line for "stalled cycles per insn" has more separators.  Each csv
output line is expected to have 8 field separators (for the 9 fields),
where as last line has 9 "," in the result. Patch fixes this issue.

The counter stats are displayed by function
"perf_stat__print_shadow_stats" in code "util/stat-shadow.c". While
printing the stats info for "stalled cycles per insn", function
"new_line_csv" is used as new_line callback.

The fields printed in each line contains: "Socket_id,aggr
nr,Avg,unit,event_name,run,enable_percent,ratio,unit"

The metric output prints Socket_id, aggr nr, ratio and unit. It has to
skip through remaining five fields ie,
Avg,unit,event_name,run,enable_percent. The csv line callback uses
"os->nfields" to know the number of fields to skip to match with other
lines.

Currently it is set as:

	os.nfields = 3 + aggr_fields[config->aggr_mode] + (counter->cgrp ? 1 : 0);

But in case of aggregation modes, csv_sep already gets printed along
with each field (Function "aggr_printout" in util/stat-display.c). So
aggr_fields can be removed from nfields. And fixed number of fields to
skip has to be "4". This is to skip fields for: "avg, unit, event name,
run, enable_percent"

This needs 4 csv separators. Patch removes aggr_fields
and uses 4 as fixed number of os->nfields to skip.

After the patch:

	# ./perf stat -x, --per-socket -a -C 1 ls
	S0,1,79.08,msec,cpu-clock,79085956,100.00,1.000,CPUs utilized
	S0,1,7,,context-switches,79084176,100.00,88.514,/sec
	------
====>	S0,1,,,,,,0.81,stalled cycles per insn

When a metric produces more than one values, it missed to print the opening
bracket.

In this context, 'os' is already a pointer so the extra dereference
isn't required. This fixes the following test failure on aarch64:

Subject: [PATCH 1441/1480] perf util: Add host_is_bigendian to util.h

Avoid libtraceevent dependency for tep_is_bigendian or trace-event.h
dependency for bigendian. Add a new host_is_bigendian to util.h, using
the compiler defined __BYTE_ORDER__ when available.

Committer notes:

Added:

 #else  /* !__BYTE_ORDER__ */

On that nested #ifdef block, as per Namhyung's suggestion.

The 'pmus' list variable is defined as static variable under pmu.c file.

Introduce a new pmus.c file and migrate this variable to it. Also make
it non static so that it can be accessed from outside.

Subject: [PATCH 1443/1480] perf test: Add event group test for events in
 multiple PMUs

Multiple events in a group can belong to one or more PMUs, however
there are some limitations.

One of the limitations is that perf doesn't allow creating a group of
events from different hw PMUs.

Write a simple test to create various combinations of hw, sw and uncore
PMU events and verify group creation succeeds or fails as expected.

Subject: [PATCH 1444/1480] machine: Adopt is_lock_function() from
 builtin-lock.c

It is used in bpf_lock_contention.c and builtin-lock.c will be made
CONFIG_LIBTRACEEVENT=y conditional, so move it to machine.c, that is
always available.

This makes those 4 global variables for sched and lock text start and
end to move to 'struct machine' too, as conceivably we can have that
info for several machine instances, say some 'perf diff' like tool.

Let's update the condition to check them explicitly.

Subject: [PATCH 1447/1480] perf jevents: Parse metrics during conversion

Currently the 'MetricExpr' json value is passed from the json
file to the pmu-events.c. This change introduces an expression
tree that is parsed into. The parsing is done largely by using
operator overloading and python's 'eval' function. Two advantages
in doing this are:

1) Broken metrics fail at compile time rather than relying on
   `perf test` to detect. `perf test` remains relevant for checking
   event encoding and actual metric use.

2) The conversion to a string from the tree can minimize the metric's
   string size, for example, preferring 1e6 over 1000000, avoiding
   multiplication by 1 and removing unnecessary whitespace. On x86
   this reduces the string size by 2,930bytes (0.07%).

In future changes it would be possible to programmatically
generate the json expressions (a single line of text and so a
pain to write manually) for an architecture using the expression
tree. This could avoid copy-pasting metrics for all architecture
variants.

v4. Doesn't simplify "0*SLOTS" to 0, as the pattern is used to fix
    Intel metrics with topdown events.
v3. Avoids generic types on standard types like set that aren't
    supported until Python 3.9, fixing an issue with Python 3.6
    reported-by John Garry. v3 also fixes minor pylint issues and adds
    a call to Simplify on the read expression tree.
v2. Improvements to type information.

From 378ef0f5d9d7f4652d7a40e0711e8b845ada1cbd Mon Sep 17 00:00:00 2001
From: Ian Rogers <irogers@google.com>
Date: Mon, 5 Dec 2022 14:59:39 -0800
Subject: [PATCH 1448/1480] perf build: Use libtraceevent from the system
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove the LIBTRACEEVENT_DYNAMIC and LIBTRACEFS_DYNAMIC make command
line variables.

If libtraceevent isn't installed or NO_LIBTRACEEVENT=1 is passed to the
build, don't compile in libtraceevent and libtracefs support.

This also disables CONFIG_TRACE that controls "perf trace".

CONFIG_LIBTRACEEVENT is used to control enablement in Build/Makefiles,
HAVE_LIBTRACEEVENT is used in C code.

Without HAVE_LIBTRACEEVENT tracepoints are disabled and as such the
commands kmem, kwork, lock, sched and timechart are removed.  The
majority of commands continue to work including "perf test".

Committer notes:

Fixed up a tools/perf/util/Build reject and added:

  #include <traceevent/event-parse.h>

to tools/perf/util/scripting-engines/trace-event-perl.c.

  #

Had to tweak tools/perf/util/setup.py to make sure the python binding
shared object links with libtraceevent if -DHAVE_LIBTRACEEVENT is
present in CFLAGS.

Building with NO_LIBTRACEEVENT=1 uncovered some more build failures:

- Make building of data-convert-bt.c to CONFIG_LIBTRACEEVENT=y

- perf-$(CONFIG_LIBTRACEEVENT) += scripts/

- bpf_kwork.o needs also to be dependent on CONFIG_LIBTRACEEVENT=y

- The python binding needed some fixups and util/trace-event.c can't be
  built and linked with the python binding shared object, so remove it
  in tools/perf/util/setup.py and exclude it from the list of
  dependencies in the python/perf.so Makefile.perf target.

Building without libtraceevent-devel installed uncovered more build
failures:

- The python binding tools/perf/util/python.c was assuming that
  traceevent/parse-events.h was always available, which was the case
  when we defaulted to using the in-kernel tools/lib/traceevent/ files,
  now we need to enclose it under ifdef HAVE_LIBTRACEEVENT, just like
  the other parts of it that deal with tracepoints.

- We have to ifdef the rules in the Build files with
  CONFIG_LIBTRACEEVENT=y to build builtin-trace.c and
  tools/perf/trace/beauty/ as we only ifdef setting CONFIG_TRACE=y when
  setting NO_LIBTRACEEVENT=1 in the make command line, not when we don't
  detect libtraceevent-devel installed in the system. Simplification here
  to avoid these two ways of disabling builtin-trace.c and not having
  CONFIG_TRACE=y when libtraceevent-devel isn't installed is the clean
  way.

From Athira:

<quote>
tools/perf/arch/powerpc/util/Build
-perf-y += kvm-stat.o
+perf-$(CONFIG_LIBTRACEEVENT) += kvm-stat.o
</quote>

Then, ditto for arm64 and s390, detected by container cross build tests.

- s/390 uses test__checkevent_tracepoint() that is now only available if
  HAVE_LIBTRACEEVENT is defined, enclose the callsite with ifder HAVE_LIBTRACEEVENT.

Also from Athira:

<quote>
With this change, I could successfully compile in these environment:
- Without libtraceevent-devel installed
- With libtraceevent-devel installed
- With “make NO_LIBTRACEEVENT=1”
</quote>

Then, finally rename CONFIG_TRACEEVENT to CONFIG_LIBTRACEEVENT for
consistency with other libraries detected in tools/perf/.

From 4171925aa9f3f7bf57b100238f148b50c45c3b1b Mon Sep 17 00:00:00 2001
From: Ian Rogers <irogers@google.com>
Date: Tue, 29 Nov 2022 22:29:35 -0800
Subject: [PATCH 1449/1480] tools lib traceevent: Remove libtraceevent

libtraceevent is now out-of-date and it is better to depend on the
system version. Remove this code that is no longer depended upon by
any builds.

Committer notes:

Removed the removed tools/lib/traceevent/ from tools/perf/MANIFEST, so
that 'make perf-tar-src-pkg' works.

-DESCRIPTION
------------
-These functions can be used to handle the mapping between pid and process name.
-The library builds a cache of these mappings, which is used to display the name
-of the process, instead of its pid. This information can be retrieved from
-tracefs/saved_cmdlines file.
-
-The _tep_register_comm()_ function registers a _pid_ / process name mapping.
-If a command with the same _pid_ is already registered, an error is returned.
-The _pid_ argument is the process ID, the _comm_ argument is the process name,
-_tep_ is the event context. The _comm_ is duplicated internally.
-
-The _tep_override_comm()_ function registers a _pid_ / process name mapping.
-If a process with the same pid is already registered, the process name string is
-udapted with the new one. The _pid_ argument is the process ID, the _comm_
-argument is the process name, _tep_ is the event context. The _comm_ is
-duplicated internally.
-
-The _tep_is_pid_registered()_ function checks if a pid has a process name
-mapping registered. The _pid_ argument is the process ID, _tep_ is the event
-context.
-
-The _tep_data_comm_from_pid()_ function returns the process name for a given
-pid. The _pid_ argument is the process ID, _tep_ is the event context.
-The returned string should not be freed, but will be freed when the _tep_
-handler is closed.
-
-The _tep_data_pid_from_comm()_ function returns a pid for a given process name.
-The _comm_ argument is the process name, _tep_ is the event context.
-The argument _next_ is the cmdline structure to search for the next pid.
-As there may be more than one pid for a given process, the result of this call
-can be passed back into a recurring call in the _next_ parameter, to search for
-the next pid. If _next_ is NULL, it will return the first pid associated with
-the _comm_. The function performs a linear search, so it may be slow.
-
-The _tep_cmdline_pid()_ function returns the pid associated with a given
-_cmdline_. The _tep_ argument is the event context.
-
-RETURN VALUE
-------------
-_tep_register_comm()_ function returns 0 on success. In case of an error -1 is
-returned and errno is set to indicate the cause of the problem: ENOMEM, if there
-is not enough memory to duplicate the _comm_ or EEXIST if a mapping for this
-_pid_ is already registered.
-
-_tep_override_comm()_ function returns 0 on success. In case of an error -1 is
-returned and errno is set to indicate the cause of the problem: ENOMEM, if there
-is not enough memory to duplicate the _comm_.
-
-_tep_is_pid_registered()_ function returns true if the _pid_ has a process name
-mapped to it, false otherwise.
-
-_tep_data_comm_from_pid()_ function returns the process name as string, or the
-string "<...>" if there is no mapping for the given pid.
-
-_tep_data_pid_from_comm()_ function returns a pointer to a struct cmdline, that
-holds a pid for a given process, or NULL if none is found. This result can be
-passed back into a recurring call as the _next_ parameter of the function.
-
-_tep_cmdline_pid()_ functions returns the pid for the give cmdline. If _cmdline_
- is NULL, then -1 is returned.
-
-EXAMPLE
--------
-The following example registers pid for command "ls", in context of event _tep_
-and performs various searches for pid / process name mappings:
-[source,c]
---
-#include <event-parse.h>
-...
-int ret;
-int ls_pid = 1021;
-struct tep_handle *tep = tep_alloc();
-...
-	ret = tep_register_comm(tep, "ls", ls_pid);
-	if (ret != 0 && errno == EEXIST)
-		ret = tep_override_comm(tep, "ls", ls_pid);
-	if (ret != 0) {
-		/* Failed to register pid / command mapping */
-	}
-...
-	if (tep_is_pid_registered(tep, ls_pid) == 0) {
-		/* Command mapping for ls_pid is not registered */
-	}
-...
-	const char *comm = tep_data_comm_from_pid(tep, ls_pid);
-	if (comm) {
-		/* Found process name for ls_pid */
-	}
-...
-	int pid;
-	struct cmdline *cmd = tep_data_pid_from_comm(tep, "ls", NULL);
-	while (cmd) {
-		pid = tep_cmdline_pid(tep, cmd);
-		/* Found pid for process "ls" */
-		cmd = tep_data_pid_from_comm(tep, "ls", cmd);

---
-
-DESCRIPTION
------------
-The _tep_list_events()_ function returns an array of pointers to the events,
-sorted by the _sort_type_ criteria. The last element of the array is NULL.
-The returned memory must not be freed, it is managed by the library.
-The function is not thread safe. The _tep_ argument is trace event parser
-context. The _sort_type_ argument is the required sort criteria:
-[verse]
---
-	_TEP_EVENT_SORT_ID_	- sort by the event ID.
-	_TEP_EVENT_SORT_NAME_	- sort by the event (name, system, id) triplet.
-	_TEP_EVENT_SORT_SYSTEM_	- sort by the event (system, name, id) triplet.
---
-
-The _tep_list_events_copy()_ is a thread safe version of _tep_list_events()_.
-It has the same behavior, but the returned array is allocated internally and
-must be freed by the caller. Note that the content of the array must not be
-freed (see the EXAMPLE below).
-
-RETURN VALUE
-------------
-The _tep_list_events()_ function returns an array of pointers to events.
-In case of an error, NULL is returned. The returned array must not be freed,
-it is managed by the library.
-
-The _tep_list_events_copy()_ function returns an array of pointers to events.
-In case of an error, NULL is returned. The returned array must be freed by
-the caller.

-SYNOPSIS

-*#include <event-parse.h>*
-*#include <trace-seq.h>*
-
-void *tep_print_event*(struct tep_handle pass:[*]_tep_, struct trace_seqpass:[*]_s_, struct tep_record pass:[*]_record_, const char pass:[*]_fmt_, _..._)
---
-
-DESCRIPTION
------------
-
-The _tep_print_event()_ function parses the event information of the given
-_record_ and writes it into the trace sequence _s_, according to the format
-string _fmt_. The desired information is specified after the format string.
-The _fmt_ is printf-like format string, following arguments are supported:
-[verse]
---
-	TEP_PRINT_PID, "%d"  - PID of the event.
-	TEP_PRINT_CPU, "%d"  - Event CPU.
-	TEP_PRINT_COMM, "%s" - Event command string.
-	TEP_PRINT_NAME, "%s" - Event name.
-	TEP_PRINT_LATENCY, "%s" - Latency of the event. It prints 4 or more
-			fields - interrupt state, scheduling state,
-			current context, and preemption count.
-			Field 1 is the interrupt enabled state:
-				d : Interrupts are disabled
-				. : Interrupts are enabled
-				X : The architecture does not support this
-				    information
-			Field 2 is the "need resched" state.
-				N : The task is set to call the scheduler when
-				    possible, as another higher priority task
-				    may need to be scheduled in.
-				. : The task is not set to call the scheduler.
-			Field 3 is the context state.
-				. : Normal context
-				s : Soft interrupt context
-				h : Hard interrupt context
-				H : Hard interrupt context which triggered
-				    during soft interrupt context.
-				z : NMI context
-				Z : NMI context which triggered during hard
-				    interrupt context
-			Field 4 is the preemption count.
-				. : The preempt count is zero.
-			On preemptible kernels (where the task can be scheduled
-			out in arbitrary locations while in kernel context), the
-			preempt count, when non zero, will prevent the kernel
-			from scheduling out the current task. The preempt count
-			number is displayed when it is not zero.
-			Depending on the kernel, it may show other fields
-			(lock depth, or migration disabled, which are unique to
-			specialized kernels).
-	TEP_PRINT_TIME, %d - event time stamp. A divisor and precision can be
-			specified as part of this format string:
-			"%precision.divisord". Example:
-			"%3.1000d" - divide the time by 1000 and print the first
-			3 digits before the dot. Thus, the time stamp
-			"123456000" will be printed as "123.456"
-	TEP_PRINT_INFO, "%s" - event information.
-	TEP_PRINT_INFO_RAW, "%s" - event information, in raw format.

-DESCRIPTION
------------
-These functions can be used to find a field and retrieve its value.
-
-The _tep_get_any_field_val()_ function searches in the _record_ for a field
-with _name_, part of the _event_. If the field is found, its value is stored in
-_val_. If there is an error and _err_ is not zero, then an error string is
-written into _s_.
-
-The _tep_get_common_field_val()_ function does the same as
-_tep_get_any_field_val()_, but searches only in the common fields. This works
-for any event as all events include the common fields.
-
-The _tep_get_field_val()_ function does the same as _tep_get_any_field_val()_,
-but searches only in the event specific fields.
-
-The _tep_get_field_raw()_ function searches in the _record_ for a field with
-_name_, part of the _event_. If the field is found, a pointer to where the field
-exists in the record's raw data is returned. The size of the data is stored in
-_len_. If there is an error and _err_ is not zero, then an error string is
-written into _s_.
-
-RETURN VALUE
-------------
-The _tep_get_any_field_val()_, _tep_get_common_field_val()_ and
-_tep_get_field_val()_ functions return 0 on success, or -1 in case of an error.
-
-The _tep_get_field_raw()_ function returns a pointer to field's raw data, and
-places the length of this data in _len_. In case of an error NULL is returned.
-
-EXAMPLE
--------
-[source,c]
---
-#include <event-parse.h>
-#include <trace-seq.h>
-...
-struct tep_handle *tep = tep_alloc();

-{
-	int len;
-	char *comm;
-	struct tep_event_format *event;
-	unsigned long long val;

-	event = tep_find_event_by_record(pevent, record);
-	if (event != NULL) {
-		if (tep_get_common_field_val(NULL, event, "common_type",
-					     record, &val, 0) == 0) {
-			/* Got the value of common type field */
-		}
-		if (tep_get_field_val(NULL, event, "pid", record, &val, 0) == 0) {

-
-void *tep_print_field*(struct trace_seq pass:[*]_s_, void pass:[*]_data_, struct tep_format_field pass:[*]_field_);

---
-
-DESCRIPTION
------------
-These functions print recorded field's data, according to the field's type.
-
-The _tep_print_field()_ function extracts from the recorded raw _data_ value of
-the _field_ and prints it into _s_, according to the field type.
-
-The _tep_print_fields()_ prints each field name followed by the record's field
-value according to the field's type:
-[verse]
---
-"field1_name=field1_value field2_name=field2_value ..."
---
-It iterates all fields of the _event_, and calls _tep_print_field()_ for each of
-them.
-
-The _tep_print_num_field()_ function prints a numeric field with given format
-string. A search is performed in the _event_ for a field with _name_. If such
-field is found, its value is extracted from the _record_ and is printed in the
-_s_, according to the given format string _fmt_. If the argument _err_ is
-non-zero, and an error occures - it is printed in the _s_.
-
-The _tep_print_func_field()_ function prints a function field with given format
-string.  A search is performed in the _event_ for a field with _name_. If such
-field is found, its value is extracted from the _record_. The value is assumed
-to be a function address, and a search is perform to find the name of this
-function. The function name (if found) and its address are printed in the _s_,
-according to the given format string _fmt_. If the argument _err_ is non-zero,
-and an error occures - it is printed in _s_.
-
-RETURN VALUE
-------------
-The _tep_print_num_field()_ and _tep_print_func_field()_ functions return 1
-on success, -1 in case of an error or 0 if the print buffer _s_ is full.

-DESCRIPTION
------------
-Filters can be attached to traced events. They can be used to filter out various
-events when outputting them. Each event can be filtered based on its parameters,
-described in the event's format file. This set of functions can be used to
-create, delete, modify and attach event filters.
-
-The _tep_filter_alloc()_ function creates a new event filter. The _tep_ argument
-is the trace event parser context.
-
-The _tep_filter_free()_ function frees an event filter and all resources that it
-had used.
-
-The _tep_filter_reset()_ function removes all rules from an event filter and
-resets it.
-
-The _tep_filter_add_filter_str()_ function adds a new rule to the _filter_. The
-_filter_str_ argument is the filter string, that contains the rule.
-
-The _tep_event_filtered()_ function checks if the event with _event_id_ has
-_filter_.
-
-The _tep_filter_remove_event()_ function removes a _filter_ for an event with
-_event_id_.
-
-The _tep_filter_match()_ function tests if a _record_ matches given _filter_.

---
-
-DESCRIPTION
------------
-Some tools may have already a way to resolve the kernel functions. These APIs
-allow them to keep using it instead of duplicating all the entries inside.
-
-The _tep_func_resolver_t_ type is the prototype of the alternative kernel
-functions resolver. This function receives a pointer to its custom context
-(set with the _tep_set_function_resolver()_ call ) and the address of a kernel
-function, which has to be resolved. In case of success, it should return
-the name of the function and its module (if any) in _modp_.
-
-The _tep_set_function_resolver()_ function registers _func_ as an alternative
-kernel functions resolver. The _tep_ argument is trace event parser context.
-The _priv_ argument is a custom context of the _func_ function. The function
-resolver is used by the APIs _tep_find_function()_,
-_tep_find_function_address()_, and _tep_print_func_field()_ to resolve
-a function address to a function name.
-
-The _tep_reset_function_resolver()_ function resets the kernel functions
-resolver to the default function.  The _tep_ argument is trace event parser
-context.
-
-
-These APIs can be used to find function name and start address, by given
-address. The given address does not have to be exact, it will select
-the function that would contain it.
-
-The _tep_find_function()_ function returns the function name, which contains the
-given address _addr_. The _tep_ argument is the trace event parser context.
-
-The _tep_find_function_address()_ function returns the function start address,
-by given address _addr_. The _addr_ does not have to be exact, it will select
-the function that would contain it. The _tep_ argument is the trace event
-parser context.
-
-The _tep_register_function()_ function registers a function name mapped to an
-address and (optional) module. This mapping is used in case the function tracer
-or events have "%pS" parameter in its format string. It is common to pass in
-the kallsyms function names with their corresponding addresses with this
-function. The _tep_ argument is the trace event parser context. The _name_ is
-the name of the function, the string is copied internally. The _addr_ is the
-start address of the function. The _mod_ is the kernel module the function may
-be in (NULL for none).
-
-The _tep_register_print_string()_ function  registers a string by the address
-it was stored in the kernel. Some strings internal to the kernel with static
-address are passed to certain events. The "%s" in the event's format field
-which has an address needs to know what string would be at that address. The
-tep_register_print_string() supplies the parsing with the mapping between kernel
-addresses and those strings. The _tep_ argument is the trace event parser
-context. The _fmt_ is the string to register, it is copied internally.
-The _addr_ is the address the string was located at.
-
-
-RETURN VALUE
-------------
-The _tep_set_function_resolver()_ function returns 0 in case of success, or -1
-in case of an error.
-
-The _tep_find_function()_ function returns the function name, or NULL in case
-it cannot be found.
-
-The _tep_find_function_address()_ function returns the function start address,
-or 0 in case it cannot be found.
-
-The _tep_register_function()_ function returns 0 in case of success. In case of
-an error -1 is returned, and errno is set to the appropriate error number.
-
-The _tep_register_print_string()_ function returns 0 in case of success. In case
-of an error -1 is returned, and errno is set to the appropriate error number.

---
-
-DESCRIPTION
------------
-These are the main functions to create and destroy tep_handle - the main
-structure, representing the trace event parser context. This context is used as
-the input parameter of most library APIs.
-
-The _tep_alloc()_ function allocates and initializes the tep context.
-
-The _tep_free()_ function will decrement the reference of the _tep_ handler.
-When there is no more references, then it will free the handler, as well
-as clean up all its resources that it had used. The argument _tep_ is
-the pointer to the trace event parser context.
-
-The _tep_ref()_ function adds a reference to the _tep_ handler.
-
-The _tep_unref()_ function removes a reference from the _tep_ handler. When
-the last reference is removed, the _tep_ is destroyed, and all resources that
-it had used are cleaned up.
-
-The _tep_ref_get()_ functions gets the current references of the _tep_ handler.
-
-RETURN VALUE
-------------
-_tep_alloc()_ returns a pointer to a newly created tep_handle structure.
-NULL is returned in case there is not enough free memory to allocate it.
-
-_tep_ref_get()_ returns the current references of _tep_.
-If _tep_ is NULL, 0 is returned.

-DESCRIPTION
------------
-These functions retrieve information from kernel context, stored in tracefs

-This information is retrieved from tracefs events/header_page, "commit" field.
-
-The _tep_get_header_timestamp_size()_ function returns the size of timestamps,
-in kernel context. The _tep_ argument is trace event parser context. This
-information is retrieved from tracefs events/header_page, "timestamp" field.
-
-The _tep_is_old_format()_ function returns true if the kernel predates
-the addition of events/header_page, otherwise it returns false.
-
-RETURN VALUE
-------------
-The _tep_get_header_page_size()_ function returns the size of a long integer,
-in bytes.
-
-The _tep_get_header_timestamp_size()_ function returns the size of timestamps,
-in bytes.
-
-The _tep_is_old_format()_ function returns true, if an old kernel is used to
-generate the tracing data, which has no event/header_page. If the kernel is new,

---
-
-DESCRIPTION
------------
-
-The _tep_is_bigendian()_ gets the endianness of the machine, executing
-the function.
-
-The _tep_is_local_bigendian()_ function gets the endianness of the local
-machine, saved in the _tep_ handler. The _tep_ argument is the trace event
-parser context. This API is a bit faster than _tep_is_bigendian()_, as it
-returns cached endianness of the local machine instead of checking it each time.
-
-The _tep_set_local_bigendian()_ function sets the endianness of the local
-machine in the _tep_ handler. The _tep_ argument is trace event parser context.
-The _endian_ argument is the endianness:
-[verse]
---
-	_TEP_LITTLE_ENDIAN_ - the machine is little endian,
-	_TEP_BIG_ENDIAN_ - the machine is big endian.
---
-
-RETURN VALUE
-------------
-The _tep_is_bigendian()_ function returns non zero if the endianness of the
-machine, executing the code, is big endian and zero otherwise.
-
-The _tep_is_local_bigendian()_ function returns true, if the endianness of the
-local machine, saved in the _tep_ handler, is big endian, or false otherwise.

-tep_parse_event, tep_parse_format - Parse the event format information
-
-SYNOPSIS
---------
-[verse]
---
-*#include <event-parse.h>*
-
-enum tep_errno *tep_parse_event*(struct tep_handle pass:[*]_tep_, const char pass:[*]_buf_, unsigned long _size_, const char pass:[*]_sys_);
-enum tep_errno *tep_parse_format*(struct tep_handle pass:[*]_tep_, struct tep_event pass:[*]pass:[*]_eventp_, const char pass:[*]_buf_, unsigned long _size_, const char pass:[*]_sys_);
---
-
-DESCRIPTION
------------
-The _tep_parse_event()_ function parses the event format and creates an event
-structure to quickly parse raw data for a given event. The _tep_ argument is
-the trace event parser context. The created event structure is stored in the
-_tep_ context. The _buf_ argument is a buffer with _size_, where the event
-format data is. The event format data can be taken from
-tracefs/events/.../.../format files. The _sys_ argument is the system of
-the event.
-
-The _tep_parse_format()_ function does the same as _tep_parse_event()_. The only
-difference is in the extra _eventp_ argument, where the newly created event
-structure is returned.
-
-RETURN VALUE
-------------
-Both _tep_parse_event()_ and _tep_parse_format()_ functions return 0 on success,
-or TEP_ERRNO__... in case of an error.

---
-
-DESCRIPTION
------------
-The _tep_parse_header_page()_ function parses the header page data from _buf_,
-and initializes the _tep_, trace event parser context, with it. The buffer
-_buf_ is with _size_, and is supposed to be copied from
-tracefs/events/header_page.
-
-Some old kernels do not have header page info, in this case the
-_tep_parse_header_page()_ function  can be called with _size_ equal to 0. The
-_tep_ context is initialized with default values. The _long_size_ can be used in
-this use case, to set the size of a long integer to be used.
-
-RETURN VALUE
-------------
-The _tep_parse_header_page()_ function returns 0 in case of success, or -1
-in case of an error.

-					       void pass:[*]data),
-			   void pass:[*]_data_);
---
-
-DESCRIPTION
------------
-The _tep_load_plugins()_ function loads all plugins, located in the plugin
-directories. The _tep_ argument is trace event parser context.
-The plugin directories are :
-[verse]
---
-	- Directories, specified in _tep_->plugins_dir with priority TEP_PLUGIN_FIRST
-	- System's plugin directory, defined at the library compile time. It
-	  depends on the library installation prefix and usually is
-	  _(install_preffix)/lib/traceevent/plugins_
-	- Directory, defined by the environment variable _TRACEEVENT_PLUGIN_DIR_
-	- User's plugin directory, located at _~/.local/lib/traceevent/plugins_
-	- Directories, specified in _tep_->plugins_dir with priority TEP_PLUGIN_LAST
---
-Loading of plugins can be controlled by the _tep_flags_, using the
-_tep_set_flag()_ API:
-[verse]
---
-	_TEP_DISABLE_SYS_PLUGINS_	- do not load plugins, located in
-					the system's plugin directory.
-	_TEP_DISABLE_PLUGINS_		- do not load any plugins.
---
-The _tep_set_flag()_ API needs to be called before _tep_load_plugins()_, if
-loading of all plugins is not the desired case.
-
-The _tep_unload_plugins()_ function unloads the plugins, previously loaded by
-_tep_load_plugins()_. The _tep_ argument is trace event parser context. The
-_plugin_list_ is the list of loaded plugins, returned by
-the _tep_load_plugins()_ function.
-
-The _tep_load_plugins_hook_ function walks through all directories with plugins
-and calls user specified _load_plugin()_ hook for each plugin file. Only files
-with given _suffix_ are considered to be plugins. The _data_ is a user specified
-context, passed to _load_plugin()_. Directories and the walk order are the same
-as in _tep_load_plugins()_ API.
-
-RETURN VALUE
-------------
-The _tep_load_plugins()_ function returns a list of successfully loaded plugins,
-or NULL in case no plugins are loaded.
-
-EXAMPLE
--------
-[source,c]
---
-#include <event-parse.h>
-...
-struct tep_handle *tep = tep_alloc();
-...
-struct tep_plugin_list *plugins = tep_load_plugins(tep);

-
-DESCRIPTION
------------
-This set of functions can be used to extract common fields from a record.
-
-The _tep_data_type()_ function gets the event id from the record _rec_.
-It reads the "common_type" field. The _tep_ argument is the trace event parser
-context.
-
-The _tep_data_pid()_ function gets the process id from the record _rec_.
-It reads the "common_pid" field. The _tep_ argument is the trace event parser
-context.
-
-The _tep_data_preempt_count()_ function gets the preemption count from the
-record _rec_. It reads the "common_preempt_count" field. The _tep_ argument is
-the trace event parser context.
-
-The _tep_data_flags()_ function gets the latency flags from the record _rec_.
-It reads the "common_flags" field. The _tep_ argument is the trace event parser
-context. Supported latency flags are:
-[verse]
---
-	_TRACE_FLAG_IRQS_OFF_,		Interrupts are disabled.
-	_TRACE_FLAG_IRQS_NOSUPPORT_,	Reading IRQ flag is not supported by the architecture.
-	_TRACE_FLAG_NEED_RESCHED_,	Task needs rescheduling.
-	_TRACE_FLAG_HARDIRQ_,		Hard IRQ is running.
-	_TRACE_FLAG_SOFTIRQ_,		Soft IRQ is running.

-unregisters a callback function to parse an event information.
-
-SYNOPSIS
---------
-[verse]
---
-*#include <event-parse.h>*
-
-enum *tep_reg_handler* {
-	_TEP_REGISTER_SUCCESS_,
-	_TEP_REGISTER_SUCCESS_OVERWRITE_,

-
-typedef int (*pass:[*]tep_event_handler_func*)(struct trace_seq pass:[*]s, struct tep_record pass:[*]record, struct tep_event pass:[*]event, void pass:[*]context);
---
-
-DESCRIPTION
------------
-The _tep_register_event_handler()_ function registers a handler function,
-which is going to be called to parse the information for a given event.
-The _tep_ argument is the trace event parser context. The _id_ argument is
-the id of the event. The _sys_name_ argument is the name of the system,
-the event belongs to. The _event_name_ argument is the name of the event.
-If _id_ is >= 0, it is used to find the event, otherwise _sys_name_ and
-_event_name_ are used. The _func_ is a pointer to the function, which is going
-to be called to parse the event information. The _context_ argument is a pointer
-to the context data, which will be passed to the _func_. If a handler function
-for the same event is already registered, it will be overridden with the new
-one. This mechanism allows a developer to override the parsing of a given event.
-If for some reason the default print format is not sufficient, the developer
-can register a function for an event to be used to parse the data instead.
-
-The _tep_unregister_event_handler()_ function unregisters the handler function,
-previously registered with _tep_register_event_handler()_. The _tep_ argument
-is the trace event parser context. The _id_, _sys_name_, _event_name_, _func_,
-and _context_ are the same arguments, as when the callback function _func_ was
-registered.
-
-The _tep_event_handler_func_ is the type of the custom event handler
-function. The _s_ argument is the trace sequence, it can be used to create a
-custom string, describing the event. A _record_  to get the event from is passed
-as input parameter and also the _event_ - the handle to the record's event. The
-_context_ is custom context, set when the custom event handler is registered.
-
-RETURN VALUE
-------------
-The _tep_register_event_handler()_ function returns _TEP_REGISTER_SUCCESS_
-if the new handler is registered successfully or
-_TEP_REGISTER_SUCCESS_OVERWRITE_ if an existing handler is overwritten.
-If there is not  enough memory to complete the registration,
-TEP_ERRNO__MEM_ALLOC_FAILED is returned.
-
-The _tep_unregister_event_handler()_ function returns 0 if _func_ was removed
-successful or, -1 if the event was not found.
-
-The _tep_event_handler_func_ should return -1 in case of an error,
-or 0 otherwise.
-
-EXAMPLE
--------

---

-
-enum *tep_func_arg_type* {
-	TEP_FUNC_ARG_VOID,
-	TEP_FUNC_ARG_INT,
-	TEP_FUNC_ARG_LONG,

-int *tep_unregister_print_function*(struct tep_handle pass:[*]_tep_, tep_func_handler _func_, char pass:[*]_name_);
---
-
-DESCRIPTION
------------
-Some events may have helper functions in the print format arguments.
-This allows a plugin to dynamically create a way to process one of
-these functions.
-
-The _tep_register_print_function()_ registers such helper function. The _tep_
-argument is the trace event parser context. The _func_ argument  is a pointer
-to the helper function. The _ret_type_ argument is  the return type of the
-helper function, value from the _tep_func_arg_type_ enum. The _name_ is the name
-of the helper function, as seen in the print format arguments. The _..._ is a
-variable list of _tep_func_arg_type_ enums, the _func_ function arguments.
-This list must end with _TEP_FUNC_ARG_VOID_. See 'EXAMPLE' section.
-
-The _tep_unregister_print_function()_ unregisters a helper function, previously
-registered with _tep_register_print_function()_. The _tep_ argument is the
-trace event parser context. The _func_ and _name_ arguments are the same, used
-when the helper function was registered.
-
-The _tep_func_handler_ is the type of the helper function. The _s_ argument is
-the trace sequence, it can be used to create a custom string.
-The _args_  is a list of arguments, defined when the helper function was
-registered.
-
-RETURN VALUE
-------------
-The _tep_register_print_function()_ function returns 0 in case of success.
-In case of an error, TEP_ERRNO_... code is returned.
-
-The _tep_unregister_print_function()_ returns 0 in case of success, or -1 in
-case of an error.
-
-EXAMPLE
--------
-Some events have internal functions calls, that appear in the print format
-output. For example "tracefs/events/i915/g4x_wm/format" has:
-[source,c]
---
-print fmt: "pipe %c, frame=%u, scanline=%u, wm %d/%d/%d, sr %s/%d/%d/%d, hpll %s/%d/%d/%d, fbc %s",
-	    ((REC->pipe) + 'A'), REC->frame, REC->scanline, REC->primary,
-	    REC->sprite, REC->cursor, yesno(REC->cxsr), REC->sr_plane,
-	    REC->sr_cursor, REC->sr_fbc, yesno(REC->hpll), REC->hpll_plane,
-	    REC->hpll_cursor, REC->hpll_fbc, yesno(REC->fbc)
---
-Notice the call to function _yesno()_ in the print arguments. In the kernel
-context, this function has the following implementation:
-[source,c]
---
-static const char *yesno(int x)
-{
-	static const char *yes = "yes";
-	static const char *no = "no";
-
-	return x ? yes : no;
-}
---
-The user space event parser has no idea how to handle this _yesno()_ function.
-The _tep_register_print_function()_ API can be used to register a user space
-helper function, mapped to the kernel's _yesno()_:
-[source,c]
---
-#include <event-parse.h>
-#include <trace-seq.h>
-...
-struct tep_handle *tep = tep_alloc();
-...
-static const char *yes_no_helper(int x)
-{
-	return x ? "yes" : "no";
-}
-...
-	if ( tep_register_print_function(tep,
-				    yes_no_helper,
-				    TEP_FUNC_ARG_STRING,
-				    "yesno",
-				    TEP_FUNC_ARG_INT,
-				    TEP_FUNC_ARG_VOID) != 0) {
-		/* Failed to register yes_no_helper function */
-	}
-
-/*
-   Now, when the event parser encounters this yesno() function, it will know
-   how to handle it.
-*/
-...
-	if (tep_unregister_print_function(tep, yes_no_helper, "yesno") != 0) {
-		/* Failed to unregister yes_no_helper function */
-	}

---
-
-DESCRIPTION
------------
-Trace event parser context flags are defined in *enum tep_flag*:
-[verse]
---
-_TEP_NSEC_OUTPUT_ - print event's timestamp in nano seconds, instead of micro seconds.
-_TEP_DISABLE_SYS_PLUGINS_ - disable plugins, located in system's plugin
-			directory. This directory is defined at library compile
-			time, and usually depends on library installation
-			prefix: (install_preffix)/lib/traceevent/plugins
-_TEP_DISABLE_PLUGINS_ - disable all library plugins:
-			- in system's plugin directory
-			- in directory, defined by the environment variable _TRACEEVENT_PLUGIN_DIR_
-			- in user's home directory, _~/.traceevent/plugins_
---
-Note: plugin related flags must me set before calling _tep_load_plugins()_ API.
-
-The _tep_set_flag()_ function sets _flag_ to _tep_ context.
-
-The _tep_clear_flag()_ function clears _flag_ from _tep_ context.
-
-The _tep_test_flag()_ function tests if _flag_ is set to _tep_ context.
-
-RETURN VALUE
-------------
-_tep_test_flag()_ function returns true if _flag_ is set, false otherwise.

-NAME
-----
-tep_strerror - Returns a string describing regular errno and tep error number.
-
-SYNOPSIS
---------
-[verse]
---
-*#include <event-parse.h>*
-
-int *tep_strerror*(struct tep_handle pass:[*]_tep_, enum tep_errno _errnum_, char pass:[*]_buf_, size_t _buflen_);
-
---
-DESCRIPTION
------------
-The _tep_strerror()_ function converts tep error number into a human
-readable string.
-The _tep_ argument is trace event parser context. The _errnum_ is a regular
-errno, defined in errno.h, or a tep error number. The string, describing this
-error number is copied in the _buf_ argument. The _buflen_ argument is
-the size of the _buf_.
-
-It as a thread safe wrapper around strerror_r(). The library function has two
-different behaviors - POSIX and GNU specific. The _tep_strerror()_ API always
-behaves as the POSIX version - the error string is copied in the user supplied
-buffer.
-
-RETURN VALUE
-------------
-The _tep_strerror()_ function returns 0, if a valid _errnum_ is passed and the
-string is copied into _buf_. If _errnum_ is not a valid error number,
--1 is returned and _buf_ is not modified.
-
-EXAMPLE
--------
-[source,c]
---
-#include <event-parse.h>
-...
-struct tep_handle *tep = tep_alloc();
-...
-char buf[32];
-char *pool = calloc(1, 128);
-if (tep == NULL) {

---
-
-DESCRIPTION
------------
-Trace sequences are used to allow a function to call several other functions
-to create a string of data to use.
-
-The _trace_seq_init()_ function initializes the trace sequence _s_.
-
-The _trace_seq_destroy()_ function destroys the trace sequence _s_ and frees
-all its resources that it had used.
-
-The _trace_seq_reset()_ function re-initializes the trace sequence _s_. All
-characters already written in _s_ will be deleted.
-
-The _trace_seq_terminate()_ function terminates the trace sequence _s_. It puts
-the null character pass:['\0'] at the end of the buffer.
-
-The _trace_seq_putc()_ function puts a single character _c_ in the trace
-sequence _s_.
-
-The _trace_seq_puts()_ function puts a NULL terminated string _str_ in the
-trace sequence _s_.
-
-The _trace_seq_printf()_ function puts a formated string _fmt _with
-variable arguments _..._ in the trace sequence _s_.
-
-The _trace_seq_vprintf()_ function puts a formated string _fmt _with
-list of arguments _args_ in the trace sequence _s_.
-
-The _trace_seq_do_printf()_ function prints the buffer of trace sequence _s_ to
-the standard output stdout.
-
-The _trace_seq_do_fprintf()_ function prints the buffer of trace sequence _s_
-to the given file _fp_.
-
-RETURN VALUE
-------------
-Both _trace_seq_putc()_ and _trace_seq_puts()_ functions return the number of
-characters put in the trace sequence, or 0 in case of an error
-
-Both _trace_seq_printf()_ and _trace_seq_vprintf()_ functions return 0 if the
-trace oversizes the buffer's free space, the number of characters printed, or
-a negative value in case of an error.
-
-Both _trace_seq_do_printf()_ and _trace_seq_do_fprintf()_ functions return the
-number of printed characters, or -1 in case of an error.

-DESCRIPTION
------------
-The libtraceevent(3) library provides APIs to access kernel tracepoint events,
-located in the tracefs file system under the events directory.
-
-ENVIRONMENT
------------
-[verse]
---
-TRACEEVENT_PLUGIN_DIR
-	Additional plugin directory. All shared object files, located in this directory will be loaded as traceevent plugins.
---
-
-FILES
------
-[verse]
---
-*event-parse.h*
-	Header file to include in order to have access to the library APIs.
-*trace-seq.h*
-	Header file to include in order to have access to trace sequences related APIs.
-	Trace sequences are used to allow a function to call several other functions
-	to create a string of data to use.
-*-ltraceevent*
-	Linker switch to add when building a program that uses the library.

- * @event_name: the name of the event
- * @func: the function to call to parse the event information

- * This function allows a developer to override the parsing of

- * for an event to be used to parse the data instead.
- *
- * If @id is >= 0, then it is used to find the event.
- * else @sys_name and @event_name are used.
- *
- * Returns:
- *  TEP_REGISTER_SUCCESS_OVERWRITE if an existing handler is overwritten
- *  TEP_REGISTER_SUCCESS if a new handler is registered successfully
- *  negative TEP_ERRNO_... in case of an error

Subject: [PATCH 1450/1480] perf tools: Check if libtracevent has
 TEP_FIELD_IS_RELATIVE

Some distros have older versions of libtraceevent where
TEP_FIELD_IS_RELATIVE and its associated semantics are not present, so
we need to check if the version has it, it was introduced in
libtraceevent 1.5.0.

Subject: [PATCH 1451/1480] perf test: Update event group check for support of
 uncore event

The event group test checks group creation for combinations of hw, sw
and uncore PMU events. Some of the uncore pmus may require additional
permission to access the counters.

For example, in case of hv_24x7, partition need to have permissions to
access hv_24x7 pmu counters. If not, event_open will fail. Hence add a
sanity check to see if event_open succeeds before proceeding with the
test.

Subject: [PATCH 1452/1480] perf off_cpu: Fix a typo in BTF tracepoint name, it
 should be 'btf_trace_sched_switch'

In BTF, tracepoint definitions have the "btf_trace_" prefix.  The
off-cpu profiler needs to check the signature of the sched_switch event
using that definition.  But there's a typo (s/bpf/btf/) so it failed
always.

Subject: [PATCH 1453/1480] perf python: Account for multiple words in CC

Sometimes build systems may append options e.g. --sysroot etc. to CC
variable especially in cross-compile environments like yocto project
where CC varable is composed of cross-compiler name and some needed
options for it to work in a relocatable environment.

Therefore separate out the compiler name from rest of the options in CC,
then add the options via second argument to Popen() API

Subject: [PATCH 1455/1480] perf lock contention: Implement -t/--threads option
 for BPF

The BPF didn't show the per-thread stat properly.  Use task's thread id (PID)
as a key instead of stack_id and add a task_data map to save task comm names.

  $ sudo ./perf lock con -abt -E 5 sleep 1

This is an error rather than just for the raw trace dump so always print

Subject: [PATCH 1459/1480] perf cs-etm: Remove unused stub methods

These aren't used outside of cs-etm so don't need stubs. Leave
cs_etm__process_auxtrace_info() which is used externally, and add an
error message so that it's obvious to users why it causes errors.

Subject: [PATCH 1460/1480] perf cs-etm: Tidy up auxtrace info header printing

cs_etm__print_auxtrace_info() is called twice in case there is an error
somewhere in cs_etm__process_auxtrace_info(), but all the info is
already available at the beginning so just print it there instead.

Also use u64 and the already cast ptr variable to make it more
consistent with the rest of the etm code.

Subject: [PATCH 1461/1480] perf cs-etm: Cleanup
 cs_etm__process_auxtrace_info()

hdr is a copy of 3 values of ptr and doesn't need to be long lived. So
just use ptr instead which means the malloc and the extra error path can
be removed to simplify things.

Subject: [PATCH 1462/1480] perf cs-etm: Print auxtrace info even if OpenCSD
 isn't linked

Printing the info doesn't have any dependency on OpenCSD, and neither
does recording Coresight data. Because it's sometimes useful to look at
the info for debugging, it makes sense to be able to see it on the same
platform that the recording was made on.

So pull the auxtrace info printing parts into a new file that is always
compiled into Perf.

Subject: [PATCH 1463/1480] perf script: Introduce task analyzer python script

Introduce a new 'perf script' to analyze task scheduling behavior.

During the task analysis, some data is always needed - which goes beyond
the simple time of switching on and off a task (process/thread). This
concerns for example the runtime of a process or the frequency with
which the process was called. This script serves to simplify this
recurring analyze process. It immediately provides the user with helpful
task characteristic information about the tasks runtimes.

Usage:

Recorded can be in two ways:

  $ perf script record tasks-analyzer -- sleep 10
  $ perf record -e sched:sched_switch -a -- sleep 10

The script can parse all perf.data files, most important: sched:sched_switch
events are mandatory, other events will be ignored.

Most simple report use case is to just call the script without arguments:

  $ perf script report tasks-analyzer
      Switched-In      Switched-Out CPU      PID      TID             Comm    Runtime     Time Out-In

  15576.659871270   15576.659902872   6    20932    20932    kworker/u16:0         32         2314582
  15576.659909951   15576.659945501   3    27264    27264               sh         36              -1
  15576.659853285   15576.659971052   7    27265    27265             perf        118         5050741
  [...]

What is not shown here are the ASCII color sequences. For example, if
the task consists of only one thread, the TID is grayed out.

Runtime is the time the task was running on the CPU, Time Out-In is the
time between the process being scheduled *out* and scheduled back *in*.
So the last time span between two executions. If -1 is printed, then the
task simply ran the first time in the measurements - a Out-In delta
could not be calculated.

In addition to the chronological representation, there is a summary on
task level. This output can be additionally switched on via the
--summary option and provides information such as max, min & average
runtime per process. The maximum runtime is often important for
debugging. The call looks like this:

  $ perf script report tasks-analyzer --summary
  Summary
       Task Information                       Runtime Information
    PID   TID            Comm Runs Accumulated    Mean  Median  Min   Max          Max At
     14    14     ksoftirqd/0   13         334      26      15    9   127 15571.621211956
     15    15     rcu_preempt  133        1778      13      13    2    33 15572.581176024
     16    16     migration/0    3          49      16      13   12    24 15571.608915425
     20    20     migration/1    3          34      11      13    8    13 15571.639101555
     25    25     migration/2    3          32      11      12    9    12 15575.639239896
  [...]

Besides these two options, there are a number of other options that change the
output and behavior. This can be queried via --help. Options worth mentioning include:

- filter-tasks         - filter out unneeded tasks, --filter-task 1337,/sbin/init
- highlight-tasks      - more pleasant focusing, --highlight-tasks 1:red,mutt:yellow
- extended-times       - show combinations of elapsed times between schedule in/schedule out
- summary-extended     - summary with additional information, like maximum delta time statistics
- rename-comms-by-tids - handy for inexpressive processnames like python, --rename 1337:my-python-app
- ms                   - show timestamps in milliseconds, nanoseconds is also possible (--ns)
- time-limit           - limit the analyzer to a time range, --time-limit 15576.0:15576.1

Script is tested and prime time ready for python2 & python3:

- make PYTHON=python3 prefix=/usr/local install
- make PYTHON=python2 prefix=/usr/local install

Subject: [PATCH 1464/1480] perf script: task-analyzer add csv support

This patch adds the possibility to write the trace and the summary as csv files
to a user specified file. A format as such simplifies further data processing.
This is achieved by having ";" as separators instead of spaces and solely one
header per file.

Additional parameters are being considered, like in the normal usage of the
script. Colors are turned off in the case of a csv output, thus the highlight
option is also being ignored.

Usage:

Write standard task to csv file:

  $ perf script report tasks-analyzer --csv <file>

write limited output to csv file in nanoseconds:

  $ perf script report tasks-analyzer --csv <file> --ns --limit-to-tasks 1337

Write summary to a csv file:

  $ perf script report tasks-analyzer --csv-summary <file>

Write summary to csv file with additional schedule information:

  $ perf script report tasks-analyzer --csv-summary <file> --summary-extended

Write both summary and standard task to a csv file:

  $ perf script report tasks-analyzer --csv --csv-summary

The following examples illustrate what is possible with the CSV output.  The
first command sequence will record all scheduler switch events for 10 seconds,
the task-analyzer calculates task information like runtimes as CSV.  A small
python snippet using pandas and matplotlib will visualize the most frequent
task (e.g. kworker/1:1) runtimes - each runtime as a bar in a bar chart:

  $ perf record -e sched:sched_switch -a -- sleep 10
  $ perf script report tasks-analyzer --ns --csv tasks.csv
  $ cat << EOF > /tmp/freq-comm-runtimes-bar.py
    import pandas as pd
    import matplotlib.pyplot as plt

    df = pd.read_csv("tasks.csv", sep=';')
    most_freq_comm = df["COMM"].value_counts().idxmax()
    most_freq_runtimes = df[df["COMM"]==most_freq_comm]["Runtime"]
    plt.title(f"Runtimes for Task {most_freq_comm} in Nanoseconds")
    plt.bar(range(len(most_freq_runtimes)), most_freq_runtimes)
    plt.show()
  $ python3 /tmp/freq-comm-runtimes-bar.py

As a seconds example, the subsequent script generates a pie chart of all
accumulated tasks runtimes for 10 seconds of system recordings:

  $ perf record -e sched:sched_switch -a -- sleep 10
  $ perf script report tasks-analyzer --csv-summary task-summary.csv
  $ cat << EOF > /tmp/accumulated-task-pie.py
    import pandas as pd
    from matplotlib.pyplot import pie, axis, show

    df = pd.read_csv("task-summary.csv", sep=';')
    sums = df.groupby(df["Comm"])["Accumulated"].sum()
    axis("equal")
    pie(sums, labels=sums.index);
    show()
  EOF
  $ python3 /tmp/accumulated-task-pie.py

A variety of other visualizations are possible in matplotlib and other
environments. Of course, pandas, numpy and co. also allow easy
statistical analysis of the data!

Subject: [PATCH 1466/1480] perf test: Add ability to test exit code for attr
 tests

Currently the return value is used to skip the test, but sometimes it
can be useful to test if a certain command should return a certain exit
code.

Subject: [PATCH 1467/1480] perf test: Add mechanism for skipping attr tests on
 auxiliary vector values

This can be used to skip tests or provide different test values on
different platforms. For example to run a test only where Arm SVE is
present add this to the config section:

  auxv    = auxv["AT_HWCAP"] & 0x200000 == 0x200000

The value is a freeform Python expression that is evaled in the context
of a map called "auxv" that contains the decoded auxiliary vector.

Subject: [PATCH 1468/1480] perf test: Add mechanism for skipping attr tests on
 kernel versions

The first two version numbers are used since that is where the ABI
changes happen, so seems to be the most useful for now.

'Until' is exclusive and 'since' is inclusive so that the same version
number can be used to mark a point where the change comes into effect.

This allows keeping the tests in a state where new tests will also pass
on older kernels if the existence of a new feature isn't explicitly
broadcast by the kernel. For example extended user regs are currently
discovered by trial and error calls to perf_event_open.

Subject: [PATCH 1470/1480] perf build: Fix python/perf.so library's name

Since Python 3.3 extensions have a suffix encoding platform and
version information. For example, the perf extension was previously
perf.so but now maybe perf.cpython-310-x86_64-linux-gnu.so. Compute
the extension using Python and then use this in the target name. Doing
this avoids the "perf.so" target always being rebuilt.

Subject: [PATCH 1471/1480] ftrace: Allow WITH_ARGS flavour of graph tracer
 with shadow call stack

The recent switch on arm64 from DYNAMIC_FTRACE_WITH_REGS to
DYNAMIC_FTRACE_WITH_ARGS failed to take into account that we currently
require the former in order to allow the function graph tracer to be
enabled in combination with shadow call stacks. This means that this is
no longer permitted at all, in spite of the fact that either flavour of
ftrace works perfectly fine in this combination.

So permit WITH_ARGS as well as WITH_REGS.

Fixes: ddc9863e9e90 ("scs: Disable when function graph tracing is enabled")

Subject: [PATCH 1473/1480] tracing: Improve panic/die notifiers

Currently the tracing dump_on_oops feature is implemented through
separate notifiers, one for die/oops and the other for panic;
given they have the same functionality, let's unify them.

Also improve the function comment and change the priority of the
notifier to make it execute earlier, avoiding showing useless trace
data (like the callback names for the other notifiers); finally,
we also removed an unnecessary header inclusion.

Subject: [PATCH 1474/1480] tracing: Fix cpumask() example typo

The sample code for using cpumask used the wrong field for the
__get_cpumask() helper. It used "cpus" which is the bitmask (but would
still give a proper example) instead of the "cpum" that was there to be
used.

Although it produces the same output, fix it, because it's an example and
is confusing in how to properly use the cpumask() macro.

Subject: [PATCH 1475/1480] perf evlist: Remove group option.

The group option predates grouping events using curly braces added in
commit 89efb029502d7f2d ("perf tools: Add support to parse event group
syntax").

The --group option was retained for legacy support (in August
2012) but keeping it adds complexity.

Subject: [PATCH 1476/1480] perf stat: Do not delay the workload with --delay

The -D/--delay option is to delay the measure after the program starts.
But the current code goes to sleep before starting the program so the
program is delayed too.  This is not the intention, let's fix it.

Before:

  $ time sudo ./perf stat -a -e cycles -D 3000 sleep 4
  Events disabled
  Events enabled

   Performance counter stats for 'system wide':

       4,326,949,337      cycles

         4.007494118 seconds time elapsed

  real	0m7.474s
  user	0m0.356s
  sys	0m0.120s

It ran the workload for 4 seconds and gave the 3 second delay.  So it
should skip the first 3 second and measure the last 1 second only.  But
as you can see, it delays 3 seconds and ran the workload after that for
4 seconds.  So the total time (real) was 7 seconds.

After:

  $ time sudo ./perf stat -a -e cycles -D 3000 sleep 4
  Events disabled
  Events enabled

   Performance counter stats for 'system wide':

       1,063,551,013      cycles

         1.002769510 seconds time elapsed

  real	0m4.484s
  user	0m0.385s
  sys	0m0.086s

The bug was introduced when it changed enablement of system-wide events
with a command line workload.  But it should've considered the initial
delay case.  The code was reworked since then (in bb8bc52e7578) so I'm
afraid it won't be applied cleanly.

From 818448e9cf92e5c6b3c10320372eefcbe4174e4f Mon Sep 17 00:00:00 2001
From: Tiezhu Yang <yangtiezhu@loongson.cn>
Date: Fri, 18 Nov 2022 17:16:39 +0800
Subject: [PATCH 1477/1480] perf tools: Use "grep -E" instead of "egrep"

The latest version of grep claims the egrep is now obsolete so the build
now contains warnings that look like:

	egrep: warning: egrep is obsolescent; using grep -E

fix this up by moving the related file to use "grep -E" instead.

  sed -i "s/egrep/grep -E/g" `grep egrep -rwl tools/perf`

Here are the steps to install the latest grep:

  wget http://ftp.gnu.org/gnu/grep/grep-3.8.tar.gz
  tar xf grep-3.8.tar.gz
  cd grep-3.8 && ./configure && make
  sudo make install
  export PATH=/usr/local/bin:$PATH

From c0cd1d541704c45030cbb2031612fdd68e8e15d5 Mon Sep 17 00:00:00 2001
From: Will Deacon <will@kernel.org>
Date: Thu, 15 Dec 2022 17:59:12 +0000
Subject: [PATCH 1478/1480] Revert "arm64: errata: Workaround possible
 Cortex-A715 [ESR|FAR]_ELx corruption"

This reverts commit 44ecda71fd8a70185c270f5914ac563827fe1d4c.

All versions of this patch on the mailing list, including the version
that ended up getting merged, have portions of code guarded by the
non-existent CONFIG_ARM64_WORKAROUND_2645198 option. Although Anshuman
says he tested the code with some additional debug changes [1], I'm
hesitant to fix the CONFIG option and light up a bunch of code right
before I (and others) disappear for the end of year holidays, during
which time we won't be around to deal with any fallout.

So revert the change for now. We can bring back a fixed, tested version
for a later -rc when folks are thinking about things other than trees
and turkeys.

Subject: [PATCH 1479/1480] libperf: Fix install_pkgconfig target

Commit 47e02b94a4c98dcc ("tools lib perf: Add dependency test to install_headers")
misses the notion of $(DESTDIR_SQ) for install_pkgconfig target, which leads to
error:

  install: cannot create regular file '/usr/lib64/pkgconfig/libperf.pc': Permission denied
  make: *** [Makefile:210: install_pkgconfig] Error 1

From dcde56bb37a9f900c11eec56b0ecaca5653cc829 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1480/1480] Fix mismerge due to devnode now taking a 'const *'
 device

This was a mismerge of a semantic conflict in my merge of the driver
core updates, where commit ff62b8e6588f ("driver core: make struct
class.devnode() take a const *") changed the devnode function pointer
type.  In the meantime, the drm tree I merged earlier had introduced a
new use of that in commit 8bf4889762a8 ("drivers/accel: define kconfig
and register a new major").

And of course this happens when I'm traveling with my laptop, and thus
didn't do a full allmodconfig build between every pull and before
pushing my work out.

So I only noticed later as I was doing my full build.
