Commit '16f17eda ("drm/amd/display: Send vblank and user events at vsartup for DCN")' introduces a new way of pageflip completion handling for DCN, and some trouble. The current implementation introduces a race condition, which can cause pageflip completion events to be sent out one vblank too early, thereby confusing userspace and causing flicker: prepare_flip_isr(): 1. Pageflip programming takes the ddev->event_lock. 2. Sets acrtc->pflip_status == AMDGPU_FLIP_SUBMITTED 3. Releases ddev->event_lock. --> Deadline for surface address regs double-buffering passes on target pipe. 4. dc_commit_updates_for_stream() MMIO programs the new pageflip into hw, but too late for current vblank. => pflip_status == AMDGPU_FLIP_SUBMITTED, but flip won't complete in current vblank due to missing the double-buffering deadline by a tiny bit. 5. VSTARTUP trigger point in vblank is reached, VSTARTUP irq fires, dm_dcn_crtc_high_irq() gets called. 6. Detects pflip_status == AMDGPU_FLIP_SUBMITTED and assumes the pageflip has been completed/will complete in this vblank and sends out pageflip completion event to userspace and resets pflip_status = AMDGPU_FLIP_NONE. => Flip completion event sent out one vblank too early. This behaviour has been observed during my testing with measurement hardware a couple of time. The commit message says that the extra flip event code was added to dm_dcn_crtc_high_irq() to prevent missing to send out pageflip events in case the pflip irq doesn't fire, because the "DCH HUBP" component is clock gated and doesn't fire pflip irqs in that state. Also that this clock gating may happen if no planes are active. This suggests that the problem addressed by that commit can't happen if planes are active. The proposed solution is therefore to only execute the extra pflip completion code iff the count of active planes is zero and otherwise leave pflip completion handling to the pflip irq handler, for a more race-free experience. Note that i don't know if this fixes the problem the original commit tried to address, as i don't know what the test scenario was. It does fix the observed too early pageflip events though and points out the problem introduced. Fixes: 16f17eda ("drm/amd/display: Send vblank and user events at vsartup for DCN") Reviewed-by:

There is the code in the read_symbol function in 'scripts/kallsyms.c': if (is_ignored_symbol(name, type)) return NULL; /* Ignore most absolute/undefined (?) symbols. */ if (strcmp(name, "_text") == 0) _text = addr; But the is_ignored_symbol function returns true for name="_text" and type='A'. So the next condition is not executed and the _text variable is always zero. It makes the wrong kallsyms_relative_base symbol as a result of the code (CONFIG_KALLSYMS_BASE_RELATIVE is defined): if (base_relative) { output_label("kallsyms_relative_base"); output_address(relative_base); printf("\n"); } Because the output_address function uses the _text variable. So the kallsyms_lookup function and all related functions in the kernel do not work properly.

There is measurable performance impact in some synthetic tests due to commit 6d390e4b (locks: fix a potential use-after-free problem when wakeup a waiter). Fix the race condition instead by clearing the fl_blocker pointer after the wake_up, using explicit acquire/release semantics. This does mean that we can no longer use the clearing of fl_blocker as the wait condition, so switch the waiters over to checking whether the fl_blocked_member list_head is empty. Reviewed-by:

This is just a cleanup addition to Jann's fix to properly update the transaction ID for the slub slowpath in commit fd4d9c7d ("mm: slub: add missing TID bump.."). The transaction ID is what protects us against any concurrent accesses, but we should really also make sure to make the 'freelist' comparison itself always use the same freelist value that we then used as the new next free pointer. Jann points out that if we do all of this carefully, we could skip the transaction ID update for all the paths that only remove entries from the lists, and only update the TID when adding entries (to avoid the ABA issue with cmpxchg and list handling re-adding a previously seen value). But this patch just does the "make sure to cmpxchg the same value we used" rather than then try to be clever. Acked-by:

When kmem_cache_alloc_bulk() attempts to allocate N objects from a percpu freelist of length M, and N > M > 0, it will first remove the M elements from the percpu freelist, then call ___slab_alloc() to allocate the next element and repopulate the percpu freelist. ___slab_alloc() can re-enable IRQs via allocate_slab(), so the TID must be bumped before ___slab_alloc() to properly commit the freelist head change.

The num_remote_opens counter keeps track of the number of open files which must be maintained by the server at any point. This is a per-tree-connect counter, and the value of this counter gets displayed in the /proc/fs/cifs/Stats output as a following... Open files: 0 total (local), 1 open on server ^^^^^^^^^^^^^^^^ As a thumb-rule, we want to increment this counter for each open/create that we successfully execute on the server. Similarly, we should decrement the counter when we successfully execute a close. In this case, an increment was being missed in case of smb2_query_dir_first, in case of successful open. As a result, we would underflow the counter and we could even see the counter go to negative after sufficient smb2_query_dir_first calls. I tested the stats counter for a bunch of filesystem operations with the fix. And it looks like the counter looks correct to me. I also check if we missed the increments and decrements elsewhere. It does not seem so. Few other cases where an open is done and we don't increment the counter are the compound calls where the corresponding close is also sent in the request. Signed-off-by:

mmc: sdhci-acpi: Switch signal voltage back to 3.3V on suspend on external microSD on Lenovo Miix 320 Based on a sample of 7 DSDTs from Cherry Trail devices using an AXP288 PMIC depending on the design one of 2 possible LDOs on the PMIC is used for the MMC signalling voltage, either DLDO3 or GPIO1LDO (GPIO1 pin in low noise LDO mode). The Lenovo Miix 320-10ICR uses GPIO1LDO in the SHC1 ACPI device's DSM methods to set 3.3 or 1.8 signalling voltage and this appears to work as advertised, so presumably the device is actually using GPIO1LDO for the external microSD signalling voltage. But this device has a bug in the _PS0 method of the SHC1 ACPI device, the DSM remembers the last set signalling voltage and the _PS0 restores this after a (runtime) suspend-resume cycle, but it "restores" the voltage on DLDO3 instead of setting it on GPIO1LDO as the DSM method does. DLDO3 is used for the LCD and setting it to 1.8V causes the LCD to go black. This commit works around this issue by calling the Intel DSM to reset the signal voltage to 3.3V after the host has been runtime suspended. This will make the _PS0 method reprogram the DLDO3 voltage to 3.3V, which leaves it at its original setting fixing the LCD going black. This commit adds and uses a DMI quirk mechanism to only trigger this workaround on the Lenovo Miix 320 while leaving the behavior of the driver unchanged on other devices.

Even though INITRAMFS_SOURCE kconfig option isn't set in most of defconfigs it is used (set) extensively by various build systems. Commit f26661e1 ("initramfs: make initramfs compression choice non-optional") has changed default compression mode. Previously we compress initramfs using available compression algorithm. Now we don't use any compression at all by default. It significantly increases the image size in case of build system chooses embedded initramfs. Initially I faced with this issue while using buildroot. As of today it's not possible to set preferred compression mode in target defconfig as this option depends on INITRAMFS_SOURCE being set. Modification of all build systems either doesn't look like good option. Let's instead rewrite initramfs compression mode choices list the way that "INITRAMFS_COMPRESSION_NONE" will be the last option in the list. In that case it will be chosen only if all other options (which implements any compression) are not available. Signed-off-by:

In order to preserve backwards compatability with kmod tools, we have to move the namespace field in Module.symvers last, as the depmod -e -E option looks at the first three fields in Module.symvers to check symbol versions (and it's expected they stay in the original order of crc, symbol, module). In addition, update an ancient comment above read_dump() in modpost that suggested that the export type field in Module.symvers was optional. I suspect that there were historical reasons behind that comment that are no longer accurate. We have been unconditionally printing the export type since 2.6.18 (commit bd5cbced), which is over a decade ago now. Fix up read_dump() to treat each field as non-optional. I suspect the original read_dump() code treated the export field as optional in order to support pre <= 2.6.18 Module.symvers (which did not have the export type field).

Pull futex fix from Thomas Gleixner: "Fix for yet another subtle futex issue. The futex code used ihold() to prevent inodes from vanishing, but ihold() does not guarantee inode persistence. Replace the inode pointer with a per boot, machine wide, unique inode identifier. The second commit fixes the breakage of the hash mechanism which causes a 100% performance regression" * tag 'locking-urgent-2020-03-15' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: futex: Unbreak futex hashing futex: Fix inode life-time issue

Pull x86 fixes from Thomas Gleixner: "Two fixes for x86: - Map EFI runtime service data as encrypted when SEV is enabled. Otherwise e.g. SMBIOS data cannot be properly decoded by dmidecode. - Remove the warning in the vector management code which triggered when a managed interrupt affinity changed outside of a CPU hotplug operation. The warning was correct until the recent core code change that introduced a CPU isolation feature which needs to migrate managed interrupts away from online CPUs under certain conditions to achieve the isolation" * tag 'x86-urgent-2020-03-15' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/vector: Remove warning on managed interrupt migration x86/ioremap: Map EFI runtime services data as encrypted for SEV
