In some places (where Y & Z are constants) a comparison of (leXX_to_cpu(X) & Y) == Z has been replaced with (X & cpu_to_leXX(Y)) == cpu_to_leXX(Z). The endian reversal of the constants should wash out at compile time.

While they have no problem with it being merged (and they've already licensed it as GPL), they don't have any interest in doing so themselves as this is an old part for them. ADI has long had an add-on card which has this part on it, so we've been keeping it up-to-date out of tree. But now that PLX has confirmed the source of the driver, we can can take the next step of cleaning it up and getting it merged. So here we are! I've done quite a large clean up of the driver and attempted to address all the common issues. Hopefully in the process, I haven't broken anything. While it seems to still work with the board that I have access to, it is not a PCI variant. So I have not tested any of the PCI logic myself (beyond clean compile). Perhaps someone who actually has a card and cares can do so. I'll try to address further feedback, but don't expect miracles. I'm not really familiar with the part itself, just the platform glue.

Then, both PIO and DMA data transfer method should be supported. But, the transfer function can returns the result immediately in PIO version, but it can't in DMA version.

This style is not useful to support host and DMAEngine in the future. But the interrupt for data transfer cannot separate easily for now, because it is deeply related to mod_gadget. This patch move the overall data transfer method into fifo.c except interrupt.

This patch move it into fifo.c. By this patch, the packet/fifo control is independent from mod_gadget.

In cascading configurations, the 9900 provides two devices per subdevice, with subvendor-ID 0xA000 and subdevice-IDs 0x30ps where p is the number of parallel ports and s the number of serial ports. Basic testing was only done on the serial part of a 9912 to the point where it can be used for a serial kernel console, and advanced features are completely untested. It is possible to reduce functionality of the chips by adding a configuration EEPROM, and the datasheet [1] is inconsistent w.r.t subdevices in the 4s+2s1p and 2s1p+4s configurations. The subdevice-ID 0x3012 should likely read 0x3011 with a serial port in function 3, which would be consistent with the BAR layouts. For now, the drivers ignore subdevices with ID 0x1000 and no class code. The parallel ports are integrated in parport_serial even for purely parallel parts to reduce the footprint of the patch.

Identify the first stage with .tagged_writepages and do livelock prevention for it, too. Jan's commit f446daaea9 ("mm: implement writeback livelock avoidance using page tagging") is a partial fix in that it only fixed the WB_SYNC_ALL phase livelock. Although ext4 is tested to no longer livelock with commit f446daaea9, it may due to some "redirty_tail() after pages_skipped" effect which is by no means a guarantee for _all_ the file systems. Note that writeback_inodes_sb() is called by not only sync(), they are treated the same because the other callers also need livelock prevention. Impact: It changes the order in which pages/inodes are synced to disk. Now in the WB_SYNC_NONE stage, it won't proceed to write the next inode until finished with the current inode.

It can prevent both of the following livelock schemes: - while true; do echo data >> f; done - while true; do touch f; done (in theory) The exact livelock condition is, during sync(1): (1) no new inodes are dirtied (2) an inode being actively dirtied On (2), the inode will be tagged and synced with .nr_to_write=LONG_MAX. When finished, it will be redirty_tail()ed because it's still dirty and (.nr_to_write > 0). redirty_tail() won't update its ->dirtied_when on condition (1). The sync work will then revisit it on the next queue_io() and find it eligible again because its old ->dirtied_when predates the sync work start time. We'll do more aggressive "keep writeback as long as we wrote something" logic in wb_writeback(). The "use LONG_MAX .nr_to_write" trick in commit b9543dac5bbc ("writeback: avoid livelocking WB_SYNC_ALL writeback") will no longer be enough to stop sync livelock.

When the queued set of inodes are all synced, they just return, possibly with all queued inode pages written but still wbc.nr_to_write > 0. For kupdate and background writeback, there may be more eligible inodes sitting in b_dirty when the current set of b_io inodes are completed. So it is necessary to try another round of writeback as long as we made some progress in this round. When there are no more eligible inodes, no more inodes will be enqueued in queue_io(), hence nothing could/will be synced and we may safely bail. For example, imagine 100 inodes i0, i1, i2, ..., i90, i91, i99 At queue_io() time, i90-i99 happen to be expired and moved to s_io for IO. When finished successfully, if their total size is less than MAX_WRITEBACK_PAGES, nr_to_write will be > 0. Then wb_writeback() will quit the background work (w/o this patch) while it's still over background threshold. This will be a fairly normal/frequent case I guess. Now that we do tagged sync and update inode->dirtied_when after the sync, this change won't livelock sync(1). I actually tried to write 1 page per 1ms with this command write-and-fsync -n10000 -S 1000 -c 4096 /fs/test and do sync(1) at the same time. The sync completes quickly on ext4, xfs, btrfs.

This _static_ timestamp may go stale if the kupdate work runs on and on. The flusher may then stuck with some old busy inodes, never considering newly expired inodes thereafter. This has two possible problems: - It is unfair for a large dirty inode to delay (for a long time) the writeback of small dirty inodes. - As time goes by, the large and busy dirty inode may contain only _freshly_ dirtied pages. Ignoring newly expired dirty inodes risks delaying the expired dirty pages to the end of LRU lists, triggering the evil pageout(). Nevertheless this patch merely addresses part of the problem. v2: keep policy changes inside wb_writeback() and keep the wbc.older_than_this visibility as suggested by Dave.

Use a consistent "refill b_io iff empty" policy which can guarantee fairness in an easy to understand way. A b_io refill will setup a _fixed_ work set with all currently eligible inodes and start a new round of walk through b_io. The "fixed" work set means no new inodes will be added to the work set during the walk. Only when a complete walk over b_io is done, new inodes that are eligible at the time will be enqueued and the walk be started over. This procedure provides fairness among the inodes because it guarantees each inode to be synced once and only once at each round. So all inodes will be free from starvations. This change relies on wb_writeback() to keep retrying as long as we made some progress on cleaning some pages and/or inodes. Without that ability, the old logic on background works relies on aggressively queuing all eligible inodes into b_io at every time. But that's not a guarantee. The below test script completes a slightly faster now: 2.6.39-rc3 2.6.39-rc3-dyn-expire+ ------------------------------------------------ all elapsed 256.043 252.367 stddev 24.381 12.530 tar elapsed 30.097 28.808 dd elapsed 13.214 11.782 #!/bin/zsh cp /c/linux-2.6.38.3.tar.bz2 /dev/shm/ umount /dev/sda7 mkfs.xfs -f /dev/sda7 mount /dev/sda7 /fs echo 3 > /proc/sys/vm/drop_caches tic=$(cat /proc/uptime|cut -d' ' -f2) cd /fs time tar jxf /dev/shm/linux-2.6.38.3.tar.bz2 & time dd if=/dev/zero of=/fs/zero bs=1M count=1000 & wait sync tac=$(cat /proc/uptime|cut -d' ' -f2) echo elapsed: $((tac - tic)) It maintains roughly the same small vs. large file writeout shares, and offers large files better chances to be written in nice 4M chunks. Analyzes from Dave Chinner in great details: Let's say we have lots of inodes with 100 dirty pages being created, and one large writeback going on. We expire 8 new inodes for every 1024 pages we write back. With the old code, we do: b_more_io (large inode) -> b_io (1l) 8 newly expired inodes -> b_io (1l, 8s) writeback large inode 1024 pages -> b_more_io b_more_io (large inode) -> b_io (8s, 1l) 8 newly expired inodes -> b_io (8s, 1l, 8s) writeback 8 small inodes 800 pages 1 large inode 224 pages -> b_more_io b_more_io (large inode) -> b_io (8s, 1l) 8 newly expired inodes -> b_io (8s, 1l, 8s) ..... Your new code: b_more_io (large inode) -> b_io (1l) 8 newly expired inodes -> b_io (1l, 8s) writeback large inode 1024 pages -> b_more_io (b_io == 8s) writeback 8 small inodes 800 pages b_io empty: (1800 pages written) b_more_io (large inode) -> b_io (1l) 14 newly expired inodes -> b_io (1l, 14s) writeback large inode 1024 pages -> b_more_io (b_io == 14s) writeback 10 small inodes 1000 pages 1 small inode 24 pages -> b_more_io (1l, 1s(24)) writeback 5 small inodes 500 pages b_io empty: (2548 pages written) b_more_io (large inode) -> b_io (1l, 1s(24)) 20 newly expired inodes -> b_io (1l, 1s(24), 20s) ...... Rough progression of pages written at b_io refill: Old code: total large file % of writeback 1024 224 21.9% (fixed) New code: total large file % of writeback 1800 1024 ~55% 2550 1024 ~40% 3050 1024 ~33% 3500 1024 ~29% 3950 1024 ~26% 4250 1024 ~24% 4500 1024 ~22.7% 4700 1024 ~21.7% 4800 1024 ~21.3% 4800 1024 ~21.3% (pretty much steady state from here) Ok, so the steady state is reached with a similar percentage of writeback to the large file as the existing code. Ok, that's good, but providing some evidence that is doesn't change the shared of writeback to the large should be in the commit message ;) The other advantage to this is that we always write 1024 page chunks to the large file, rather than smaller "whatever remains" chunks.

Notes about the tmpfs/ramfs behavior changes: As for 2.6.36 and older kernels, the tmpfs writes will sleep inside balance_dirty_pages() as long as we are over the (dirty+background)/2 global throttle threshold. This is because both the dirty pages and threshold will be 0 for tmpfs/ramfs. Hence this test will always evaluate to TRUE: dirty_exceeded = (bdi_nr_reclaimable + bdi_nr_writeback >= bdi_thresh) || (nr_reclaimable + nr_writeback >= dirty_thresh); For 2.6.37, someone complained that the current logic does not allow the users to set vm.dirty_ratio=0. So commit 4cbec4c8b9 changed the test to dirty_exceeded = (bdi_nr_reclaimable + bdi_nr_writeback > bdi_thresh) || (nr_reclaimable + nr_writeback > dirty_thresh); So 2.6.37 will behave differently for tmpfs/ramfs: it will never get throttled unless the global dirty threshold is exceeded (which is very unlikely to happen; once happen, will block many tasks). I'd say that the 2.6.36 behavior is very bad for tmpfs/ramfs. It means for a busy writing server, tmpfs write()s may get livelocked! The "inadvertent" throttling can hardly bring help to any workload because of its "either no throttling, or get throttled to death" property. So based on 2.6.37, this patch won't bring more noticeable changes.

Non-SCI parts do not have the special port reg necessary for cases where the RX and SCI pins are muxed and need to be manually polled, so these like always fall back on the normal FIFO processing paths. SH7760 is in a class in and of itself with regards to mapping its SIM card interface via the SCI port class despite not having any of the RXD lines wired up and so implicitly behaving more like a SCIF in this regard. Out of the other CPUs, some support the port check via the same block while others do it through an external SuperI/O, so it's not even possible to perform the check relative to the ioremapped cookie offset, so the separate read semantics are preserved here, too.

The reason for this is because cgroupfs creates files and directories during the get_sb() call and also uses lookup_one_len() during that same get_sb() call. This is a problem since the security subsystem cannot initialize the superblock and the inodes in that filesystem until after the get_sb() call returns. Thus we leave the inodes in an unitialized state during get_sb(). For the vast majority of filesystems this is not an issue, but since cgroupfs uses lookup_on_len() it does search permission checks on the directories in the path it walks. Since the inode security state is not set up SELinux does these checks as if the inodes were 'unlabeled.' Many 'normal' userspace process do not have permission to interact with unlabeled inodes. The solution presented here is to do the permission checks of path walk and inode creation as the kernel rather than as the task that called mount. Since the kernel has permission to read/write/create unlabeled inodes the get_sb() call will complete successfully and the SELinux code will be able to initialize the superblock and those inodes created during the get_sb() call. This appears to be the same solution used by other filesystems such as devtmpfs to solve the same issue and should thus have no negative impact on other LSMs which currently work.

Instead, the system reboots to the good kernel. Since the good kernel may display a boot prompt that matches the success string, ktest may think that the test succeeded, when it did not. Detecting triple faults is tricky because it is hard to generalize what a reboot looks like. The best that we can come up with for now is to examine the Linux banner. If we detect that the Linux banner matches the test we want to test, then look to see if we hit another Linux banner with a different kernel is booted. This can be assumed to be a triple fault. We can't just check for two Linux banners because things like early printk may cause the Linux banner to be displayed twice. Checking for different kernel versions should be the safe bet. If this for some reason detects a false triple boot. A new ktest config option is also created: DETECT_TRIPLE_FAULT This can be set to 0 to disable this checking.

There may be another config that we know is good that we want to ignore configs on. By passing in this config it will ignore the options that are set in the good config. Note: This only ignores the config, it does not (yet) handle options that are different between the two configs. If the good config has "SLAB" set and the bad config has "SLUB" it will not find the bug if the bug had to do with changing these two options. This is something that I intend to implement in the future.

This is to get things like call traces and enough infromation about the bug to help determine what caused it. The STOP_AFTER_FAILURE is usually much shorter than the TIMEOUT that is used to determine when to quit after no more stdio is given. But since the stdio read uses a wait on I/O, the STOP_AFTER_FAILURE is only checked after we get something from I/O. But if the I/O does not return any more data, we wait the TIMEOUT period instead, even though we already triggered a bug report. The wait on I/O should honor the STOP_AFTER_FAILURE time if a bug has been found.

This takes a bit of a sledgehammer to the horribly CPU subtype ifdef-ridden header and abstracts all of the different register layouts in to distinct types which in turn can be overriden on a per-port basis, or permitted to default to the map matching the port type at probe time. In the process this ultimately fixes up inumerable bugs with mismatches on various CPU types (particularly the legacy ones that were obviously broken years ago and no one noticed) and provides a more tightly coupled and consolidated platform for extending and implementing generic features.

This consolidates all of the TX/RX fill/room nonsense in to a single set of fairly heavyweight definitions. The implementation goes in descending order of complexity, testing the register map for capabilities until we run out of options and do it the legacy SCI way. Masks are derived directly from the per-port FIFO size, meaning that platforms with FIFO sizes not matching the standard port types will still need to manually fix them up. This also fixes up a number of issues such as tx_empty being completely bogus for SCI and IrDA ports, some ports using masks smaller or greater than their FIFO size, and so forth.

This changes arch/powerpc/kernel/smp.c so that if smp_ops->message_pass is NULL, it calls smp_muxed_ipi_message_pass directly. This means that a platform doesn't need to set both .message_pass and .cause_ipi, only one of them. It is a slight performance improvement in that it gets rid of an indirect function call at the expense of a predictable conditional branch.

We expect this is actually faster, and we end up needing more space than we can get from the SPRGs in some instances. This is also useful when running as a guest OS - SPRGs4-7 do not have guest versions. 8 slots are allocated in thread_info for this even though we only actually use 4 of them - this allows space for future code to have more scratch space (and we know we'll need it for things like hugetlb).

Once I'm fairly confident we're okay, it'll be removed. There's a number of things not implemented by this fuc currently, but most of it is sets of state that our context setup would not have used anyway. No doubt we'll find out what they're for at some point, and implement it if required. This has been tested on 0xc0/0xc4 thus far, and from what I could tell it worked as well as NVIDIA's. It's also been tested on 0xc1, but even with NVIDIA's fuc that chipset doesn't work correctly with nouveau yet. 0xc3/0xc8/0xce should in theory be supported too, but I don't have the hardware to check that. There's no doubt numerous bugs to squash yet, please report any!

Two different changes are made: 1) Delay disabling of clocks until late in the boot process. This fixes an existing issue where in-use clocks without software reference are disabled by mistake during boot. One example of this is the handling of the Mackerel serial console output that shares clock with the I2C controller. 2) Write out the "disabled" state to the hardware for clocks that not have been used by the kernel. In other words, make sure so far unused clocks actually get turned off.

It has been based on fixed tracepoints for jbd2, however there are missing those for collecting statistics, since I think that it will require more intrusive patch so I should have its own commit, if someone decide that it is needed. Also there are new tracepoints in __journal_drop_transaction() and journal_update_superblock(). The list of jbd tracepoints: jbd_checkpoint jbd_start_commit jbd_commit_locking jbd_commit_flushing jbd_commit_logging jbd_drop_transaction jbd_end_commit jbd_do_submit_data jbd_cleanup_journal_tail jbd_update_superblock_end Signed-off-by: Lukas Czerner Cc: Jan Kara Signed-off-by: Jan Kara --- fs/jbd/checkpoint.c | 4 + fs/jbd/commit.c | 11 ++ fs/jbd/journal.c | 4 + include/trace/events/jbd.h | 203 +++++++++++++++++++++++++++++++++++++ 4 files changed, 222 insertions(+) create mode 100644 include/trace/events/jbd.h diff --git a/fs/jbd/checkpoint.c b/fs/jbd/checkpoint.c index e4b87bc1fa56e..dea7503b47e8f 100644 --- a/fs/jbd/checkpoint.c +++ b/fs/jbd/checkpoint.c @@ -22,6 +22,7 @@ #include #include #include +#include /* * Unlink a buffer from a transaction checkpoint list. @@ -358,6 +359,7 @@ int log_do_checkpoint(journal_t *journal) * journal straight away. */ result = cleanup_journal_tail(journal);

Block reservation code does not expect two concurrent allocations to happen to the same inode and thus assertions can be triggered or reservation structure corruption can occur.

This is caused for example by the following race: TASK1 TASK2 journal_commit_transaction() ... processing t_forget list __journal_refile_buffer(jh); if (!jh->b_transaction) { jbd_unlock_bh_state(bh); journal_try_to_free_buffers() journal_grab_journal_head(bh) jbd_lock_bh_state(bh) __journal_try_to_free_buffer() journal_put_journal_head(jh) journal_remove_journal_head(bh); journal_put_journal_head() in TASK2 sees that b_jcount == 0 and buffer is not part of any transaction and thus frees journal_head before TASK1 gets to doing so. Note that even buffer_head can be released by try_to_free_buffers() after journal_put_journal_head() which adds even larger opportunity for oops (but I didn't see this happen in reality). Fix the problem by making transactions hold their own journal_head reference (in b_jcount). That way we don't have to remove journal_head explicitely via journal_remove_journal_head() and instead just remove journal_head when b_jcount drops to zero. The result of this is that [__]journal_refile_buffer(), [__]journal_unfile_buffer(), and __journal_remove_checkpoint() can free journal_head which needs modification of a few callers. Also we have to be careful because once journal_head is removed, buffer_head might be freed as well. So we have to get our own buffer_head reference where it matters.

This patch introduces the new format 'ecryptfs' that allows to store an authentication token structure inside the encrypted key payload containing a randomly generated symmetric key, as the same for the format 'default'. More details about the usage of encrypted keys with the eCryptfs filesystem can be found in the file 'Documentation/keys-ecryptfs.txt'.

The following steps need to be performed to make an hcall: 1. Load r11 with the hcall number 2. Load specific other registers with parameters 3. Issue instrucion "sc 1" 4. The return code is in r3 5. Other returned parameters are in other registers. To provide this service to the kernel, these steps are wrapped in inline assembly functions. Standard ePAPR hcalls are in epapr_hcalls.h, and Freescale extensions are in fsl_hcalls.h.

This is called the VMPIC. The ePAPR "virtual interrupt controller" provides interrupt controller services for external interrupts. External interrupts received by a partition can come from two sources: - Hardware interrupts - hardware interrupts come from external interrupt lines or on-chip I/O devices. - Virtual interrupts - virtual interrupts are generated by the hypervisor as part of some hypervisor service or hypervisor-created virtual device. Both types of interrupts are processed using the same programming model and same set of hypercalls.

In journal checkpoint, we write the buffer and wait for its finish. But in cfq, the async queue has a very low priority, and in our test, if there are too many sync queues and every queue is filled up with requests, and the process will hang waiting for the log space. So this patch tries to use WRITE_SYNC in __flush_batch so that the request will be moved into sync queue and handled by cfq timely. We also use the new plug, sot that all the WRITE_SYNC requests can be given as a whole when we unplug it.

Later, we can add an atomic notifier to tell interested drivers about what's happening with the controller. Notifications such as suspend, resume, enumerated, etc. will be useful, at a minimum, for implementing usb charger detection. As part of the converting process usb_gadget_probe_driver() is no longer part of each udc but pushed into the ->stap() callback. The same for his couterpart. The core is currently set explicit to 'n'. It will be changed to 'y' once all users are converted since it provides functions which clash with other drivers.

This optimization spares the FDs from saving the endpoint chosen descriptor. This optimization is not full though. To fully exploit this change, one needs to update all the UDCs as well since in the current implementation each of them saves the endpoint descriptor in it's internal (and extended) endpoint structure.

The main downside of keeping the ring frequency high while the CPU is at a low frequency (or asleep altogether) is increased power consumption. But then if you're keeping your GPU busy, you probably want the extra performance. v2: - add units to debug table header (from Eric) - use tsc_khz as a fallback if the cpufreq driver doesn't give us a freq (from Chris) v3: - fix comments & debug output - remove unneeded force wake get/put Reviewed-by: Ben Widawsky Tested-by: Eric Anholt Reviewed-by: Eric Anholt Signed-off-by: Jesse Barnes Signed-off-by: Keith Packard --- drivers/gpu/drm/i915/i915_debugfs.c | 39 +++++++++++++++++++ drivers/gpu/drm/i915/i915_reg.h | 4 +- drivers/gpu/drm/i915/i915_suspend.c | 4 +- drivers/gpu/drm/i915/intel_display.c | 58 +++++++++++++++++++++++++++- drivers/gpu/drm/i915/intel_drv.h | 1 + 5 files changed, 103 insertions(+), 3 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_debugfs.c b/drivers/gpu/drm/i915/i915_debugfs.c index 4d46441cbe2d8..8a5a032ec6961 100644 --- a/drivers/gpu/drm/i915/i915_debugfs.c +++ b/drivers/gpu/drm/i915/i915_debugfs.c @@ -1123,6 +1123,44 @@ static int i915_emon_status(struct seq_file *m, void *unused) return 0; } +static int i915_ring_freq_table(struct seq_file *m, void *unused) +{ + struct drm_info_node *node = (struct drm_info_node *) m->private; + struct drm_device *dev = node->minor->dev; + drm_i915_private_t *dev_priv = dev->dev_private; + int ret; + int gpu_freq, ia_freq; + + if (!IS_GEN6(dev)) { + seq_printf(m, "unsupported on this chipset\n"); + return 0; + } + + ret = mutex_lock_interruptible(&dev->struct_mutex); + if (ret) + return ret; + + seq_printf(m, "GPU freq (MHz)\tEffective CPU freq (MHz)\n"); + + for (gpu_freq = dev_priv->min_delay; gpu_freq <= dev_priv->max_delay; + gpu_freq++) { + I915_WRITE(GEN6_PCODE_DATA, gpu_freq); + I915_WRITE(GEN6_PCODE_MAILBOX, GEN6_PCODE_READY | + GEN6_PCODE_READ_MIN_FREQ_TABLE); + if (wait_for((I915_READ(GEN6_PCODE_MAILBOX) & + GEN6_PCODE_READY) == 0, 10)) { + DRM_ERROR("pcode read of freq table timed out\n"); + continue; + } + ia_freq = I915_READ(GEN6_PCODE_DATA); + seq_printf(m, "%d\t\t%d\n", gpu_freq * 50, ia_freq * 100); + } + + mutex_unlock(&dev->struct_mutex); + + return 0; +} + static int i915_gfxec(struct seq_file *m, void *unused) { struct drm_info_node *node = (struct drm_info_node *) m->private; @@ -1426,6 +1464,7 @@ static struct drm_info_list i915_debugfs_list[] = { {"i915_inttoext_table", i915_inttoext_table, 0}, {"i915_drpc_info", i915_drpc_info, 0}, {"i915_emon_status", i915_emon_status, 0}, + {"i915_ring_freq_table", i915_ring_freq_table, 0}, {"i915_gfxec", i915_gfxec, 0}, {"i915_fbc_status", i915_fbc_status, 0}, {"i915_sr_status", i915_sr_status, 0}, diff --git a/drivers/gpu/drm/i915/i915_reg.h b/drivers/gpu/drm/i915/i915_reg.h index 5d5def756c9e5..4a446b116e6aa 100644 --- a/drivers/gpu/drm/i915/i915_reg.h +++ b/drivers/gpu/drm/i915/i915_reg.h @@ -3434,7 +3434,9 @@ #define GEN6_PCODE_MAILBOX 0x138124 #define GEN6_PCODE_READY (1<<31) #define GEN6_READ_OC_PARAMS 0xc -#define GEN6_PCODE_WRITE_MIN_FREQ_TABLE 0x9 +#define GEN6_PCODE_WRITE_MIN_FREQ_TABLE 0x8 +#define GEN6_PCODE_READ_MIN_FREQ_TABLE 0x9 #define GEN6_PCODE_DATA 0x138128 +#define GEN6_PCODE_FREQ_IA_RATIO_SHIFT 8 #endif /* _I915_REG_H_ */ diff --git a/drivers/gpu/drm/i915/i915_suspend.c b/drivers/gpu/drm/i915/i915_suspend.c index e8152d23d5b67..6fbd997f5a6c8 100644 --- a/drivers/gpu/drm/i915/i915_suspend.c +++ b/drivers/gpu/drm/i915/i915_suspend.c @@ -875,8 +875,10 @@ int i915_restore_state(struct drm_device *dev) intel_init_emon(dev); } - if (IS_GEN6(dev)) + if (IS_GEN6(dev)) { gen6_enable_rps(dev_priv); + gen6_update_ring_freq(dev_priv); + } /* Cache mode state */ I915_WRITE (CACHE_MODE_0, dev_priv->saveCACHE_MODE_0 | 0xffff0000); diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index e58627f580c68..804ac4d6cb482 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -24,6 +24,7 @@ * Eric Anholt */ +#include #include #include #include @@ -7273,6 +7274,59 @@ void gen6_enable_rps(struct drm_i915_private *dev_priv) mutex_unlock(&dev_priv->dev->struct_mutex); } +void gen6_update_ring_freq(struct drm_i915_private *dev_priv) +{ + int min_freq = 15; + int gpu_freq, ia_freq, max_ia_freq; + int scaling_factor = 180; + + max_ia_freq = cpufreq_quick_get_max(0); + /* + * Default to measured freq if none found, PCU will ensure we don't go + * over + */ + if (!max_ia_freq) + max_ia_freq = tsc_khz; + + /* Convert from kHz to MHz */ + max_ia_freq /= 1000; + + mutex_lock(&dev_priv->dev->struct_mutex); + + /* + * For each potential GPU frequency, load a ring frequency we'd like + * to use for memory access.

In order to synchronize with TOMOYO 1.8's syntax, (1) Remove special handling for allow_read/write permission. (2) Replace deny_rewrite/allow_rewrite permission with allow_append permission. (3) Remove file_pattern keyword. (4) Remove allow_read permission from exception policy. (5) Allow creating domains in enforcing mode without calling supervisor. (6) Add permission check for opening directory for reading. (7) Add permission check for stat() operation. (8) Make "cat < /sys/kernel/security/tomoyo/self_domain" behave as if "cat /sys/kernel/security/tomoyo/self_domain".

Use common structure for ACL with "struct list_head" + "atomic_t". Use array/struct where possible. Remove is_group from "struct tomoyo_name_union"/"struct tomoyo_number_union". Pass "struct file"->private_data rather than "struct file". Update some of comments. Bring tomoyo_same_acl_head() from common.h to domain.c . Bring tomoyo_invalid()/tomoyo_valid() from common.h to util.c .

Add /sys/kernel/security/tomoyo/audit interface. This interface generates audit logs in the form of domain policy so that /usr/sbin/tomoyo-auditd can reuse audit logs for appending to /sys/kernel/security/tomoyo/domain_policy interface.

Mauras Olivier reported that it is difficult to use TOMOYO in LXC environments, for TOMOYO cannot distinguish between environments outside the container and environments inside the container since LXC environments are created using pivot_root(). To address this problem, this patch introduces policy namespace. Each policy namespace has its own set of domain policy, exception policy and profiles, which are all independent of other namespaces. This independency allows users to develop policy without worrying interference among namespaces.

TOMOYO wants to use /proc/self/ rather than /proc/$PID/ if $PID matches current thread's process ID in order to prevent current thread from accessing other process's information unless needed. But since procfs can be mounted on various locations (e.g. /proc/ /proc2/ /p/ /tmp/foo/100/p/ ), TOMOYO cannot tell that whether the numeric part in the string returned by __d_path() represents process ID or not. Therefore, to be able to convert from $PID to self no matter where procfs is mounted, this patch changes pathname representations for filesystems which do not support rename() operation (e.g. proc, sysfs, securityfs). Examples: /proc/self/mounts => proc:/self/mounts /sys/kernel/security/ => sys:/kernel/security/ /dev/pts/0 => devpts:/0 Signed-off-by: Tetsuo Handa Signed-off-by: James Morris --- security/tomoyo/file.c | 12 +- security/tomoyo/realpath.c | 222 +++++++++++++++++++++++++++++-------- 2 files changed, 180 insertions(+), 54 deletions(-) diff --git a/security/tomoyo/file.c b/security/tomoyo/file.c index 323ddc73a125d..8410f28a35e00 100644 --- a/security/tomoyo/file.c +++ b/security/tomoyo/file.c @@ -712,7 +712,7 @@ int tomoyo_path_number_perm(const u8 type, struct path *path, int idx;

Currently TOMOYO holds SRCU lock upon open() and releases it upon close() because list elements stored in the "struct tomoyo_io_buffer" instances are accessed until close() is called. However, such SRCU usage causes lockdep to complain about leaving the kernel with SRCU lock held. This patch solves the warning by holding/releasing SRCU upon each read()/write(). This patch is doing something similar to calling kfree() without calling synchronize_srcu(), by selectively deferring kfree() by keeping track of the "struct tomoyo_io_buffer" instances.

To be able to start using enforcing mode from the early stage of boot sequence, this patch adds support for activating access control without calling external policy loader program. This will be useful for systems where operations which can lead to the hijacking of the boot sequence are needed before loading the policy. For example, you can activate immediately after loading the fixed part of policy which will allow only operations needed for mounting a partition which contains the variant part of policy and verifying (e.g. running GPG check) and loading the variant part of policy. Since you can start using enforcing mode from the beginning, you can reduce the possibility of hijacking the boot sequence. This patch makes several variables configurable on build time. This patch also adds TOMOYO_loader= and TOMOYO_trigger= kernel command line option to boot the same kernel in two different init systems (BSD-style init and systemd).

This is wrong, in complain mode the profile has effectively all capabilities, as the profile restrictions are not being enforced, merely tested against to determine if an access is known by the profile. This can result in the wrong behavior of security conscience applications like sshd which examine their capability set, and change their behavior accordingly. In this case because of the masked capability set being returned sshd fails due to DAC checks, even when the profile is in complain mode. Kernels affected: 2.6.36 - 3.0.

If on top of that we do a full table walk, we get rid of all recursive TLB faults, and can dispense with some state saving. This gains a few percent on TLB-miss-heavy workloads, and around 50% on a benchmark that had a high rate of virtual page table faults under the normal handler. While touching the EX_TLB layout, remove EX_TLB_MMUCR0, EX_TLB_SRR0, and EX_TLB_SRR1 as they're not used.

However, this is really just a transport to the service processor which implements them either as "raw" console (networked consoles, HMC, ...) or as "hvsi" serial ports. The later is a simple packet protocol on top of the raw character interface that is supposed to convey additional "serial port" style semantics. In practice however, all it does is provide a way to read the CD line and set/clear our DTR line, that's it. We currently implement the "raw" protocol as an hvc console backend (/dev/hvcN) and the "hvsi" protocol using a separate tty driver (/dev/hvsi0). However this is quite impractical. The arbitrary difference between the two type of devices has been a major source of user (and distro) confusion. Additionally, there's an additional mini -hvsi implementation in the pseries platform code for our low level debug console and early boot kernel messages, which means code duplication, though that low level variant is impractical as it's incapable of doing the initial protocol negociation to establish the link to the FSP. This essentially replaces the dedicated hvsi driver and the platform udbg code completely by extending the existing hvc_vio backend used in "raw" mode so that: - It now supports HVSI as well - We add support for hvc backend providing tiocm{get,set} - It also provides a udbg interface for early debug and boot console This is overall less code, though this will only be obvious once we remove the old "hvsi" driver, which is still available for now. When the old driver is enabled, the new code still kicks in for the low level udbg console, replacing the old mini implementation in the platform code, it just doesn't provide the higher level "hvc" interface. In addition to producing generally simler code, this has several benefits over our current situation: - The user/distro only has to deal with /dev/hvcN for the hypervisor console, avoiding all sort of confusion that has plagued us in the past - The tty, kernel and low level debug console all use the same code base which supports the full protocol establishment process, thus the console is now available much earlier than it used to be with the old HVSI driver. The kernel console works much earlier and udbg is available much earlier too. Hackers can enable a hard coded very-early debug console as well that works with HVSI (previously that was only supported for the "raw" mode). I've tried to keep the same semantics as hvsi relative to how I react to things like CD changes, with some subtle differences though: - I clear DTR on close if HUPCL is set - Current hvsi triggers a hangup if it detects a up->down transition on CD (you can still open a console with CD down). My new implementation triggers a hangup if the link to the FSP is severed, and severs it upon detecting a up->down transition on CD.

Unlike x86 and sparc we just merrily patch the code with no locks etc, as far as I know this is safe, but I'm not really sure what the x86/sparc code is protecting against so maybe it's not. I also don't see any reason for us to implement the poke_early() routine, even though sparc does.

This patch changes this behavior to allow a retry through returning -EAGAIN. This change also affects the hvc_push() function. Both functions are changed to handle -EAGAIN and to retry the put_chars() operation. If a hvc backend returns -EAGAIN, the retry handling differs: - hvc_console_print() spins to write the complete console output. - hvc_push() behaves the same way as for returning 0. Now hvc backends can indirectly control the way how console output is handled through the hvc console layer.

Unfortunately hvterm_raw_get_chars returns -EAGAIN if you ask for anything less than 16 characters. As a result xmon no longer accepts input and prints a stream of junk to the screen. The recent change highlights a problem that xmon on pseries VIO has had all along, that it can drop input characters. The issue is the hypervisor call does not take a count argument and can return up to 16 characters. This patch adds a per vterm buffer that we copy input data into and give it out as requested.

The qh_update() routine needs to know the number and direction of the endpoint corresponding to its QH argument. The number can be taken directly from the QH data structure, but the direction isn't stored there. The direction is taken instead from the first qTD linked to the QH. However, it turns out that for interrupt transfers, qh_update() gets called before the qTDs are linked to the QH. As a result, qh_update() computes a bogus direction value, which messes up the endpoint toggle handling. Under the right combination of circumstances this causes usb_reset_endpoint() not to work correctly, which causes packets to be dropped and communications to fail. Now, it's silly for the QH structure not to have direct access to all the descriptor information for the corresponding endpoint. Ultimately it may get a pointer to the usb_host_endpoint structure; for now, adding a copy of the direction flag solves the immediate problem. This allows the Spyder2 color-calibration system (a low-speed USB device that sends all its interrupt data packets with the toggle set to 0 and hance requires constant use of usb_reset_endpoint) to work when connected through a high-speed hub. Thanks to Graeme Gill for supplying the hardware that allowed me to track down this bug.

In a platform where ADC's VDD regulator is not "always-on", this control is required although this patch does not provide fine-grained power control (turning on the regulator only when being accessed). However, if VDD regulator ("vdd" for the adc device) is not provided, the regulator control will not be activated because there are platforms that do not provide regulator for ADC device. arch_initcall has been modified to module_init in order to allow regulators to be available at probe.
