2024-09-05drm/fbdev-dma: Only install deferred I/O if necessaryThomas Zimmermann
Deferred I/O requires struct page for framebuffer memory, which is not guaranteed for all DMA ranges. We thus only install deferred I/O if we have a framebuffer that requires it. A reported bug affected the ipu-v3 and pl111 drivers, which have video memory in either Normal or HighMem zones [ 0.000000] Zone ranges: [ 0.000000] Normal [mem 0x0000000010000000-0x000000003fffffff] [ 0.000000] HighMem [mem 0x0000000040000000-0x000000004fffffff] where deferred I/O only works correctly with HighMem.

The WL-355608-A8 is a 3.5" 640x480@60Hz RGB LCD display from an unknown OEM used in a number of handheld gaming devices made by Anbernic. Previously committed using the OEM serial without a vendor prefix, however following subsequent discussion the preference is to use the integrating device vendor and name where the OEM is unknown. There are 4 RG35XX series devices from Anbernic based on an Allwinner H700 SoC using this panel, with the -Plus variant introduced first. Therefore the -Plus is used as the fallback for the subsequent -H, -2024, and -SP devices. Alter the filename and compatible string to reflect the convention.

2024-09-05drm/panthor: Restrict high priorities on group_createMary Guillemard
We were allowing any users to create a high priority group without any permission checks. As a result, this was allowing possible denial of service. We now only allow the DRM master or users with the CAP_SYS_NICE capability to set higher priorities than PANTHOR_GROUP_PRIORITY_MEDIUM. As the sole user of that uAPI lives in Mesa and hardcode a value of MEDIUM [1], this should be safe to do. Additionally, as those checks are performed at the ioctl level, panthor_group_create now only check for priority level validity.

The commit 'b1d90a86 ("drm/xe: Use the encoder suspend helper also used by the i915 driver")' didn't do anything wrong. It actually fixed a critical bug, because the encoder_suspend was never getting actually called because it was returning if (has_display(xe)) instead of if (!has_display(xe)). However, this ended up introducing the encoder suspend calls in the runtime routines as well, causing the circular locking dependency.

Therefore, if GSC failed to load previously there is no need to try again because the HW is stuck in the error state.

2024-09-02drm/i915: Fix readout degamma_lut mismatch on ilk/snbVille Syrjälä
On ilk/snb the pipe may be configured to place the LUT before or after the CSC depending on various factors, but as there is only one LUT (no split mode like on IVB+) we only advertise a gamma_lut and no degamma_lut in the uapi to avoid confusing userspace. This can cause a problem during readout if the VBIOS/GOP enabled the LUT in the pre CSC configuration. The current code blindly assigns the results of the readout to the degamma_lut, which will cause a failure during the next atomic_check() as we aren't expecting anything to be in degamma_lut since it's not visible to userspace. Fix the problem by assigning whatever LUT we read out from the hardware into gamma_lut.

2024-09-02drm/i915: Do not attempt to load the GSC multiple timesDaniele Ceraolo Spurio
If the GSC FW fails to load the GSC HW hangs permanently; the only ways to recover it are FLR or D3cold entry, with the former only being supported on driver unload and the latter only on DGFX, for which we don't need to load the GSC. Therefore, if GSC fails to load there is no need to try again because the HW is stuck in the error state and the submission to load the FW would just hang the GSCCS. Note that, due to wa_14015076503, on MTL the GuC escalates all GSCCS hangs to full GT resets, which would trigger a new attempt to load the GSC FW in the post-reset HW re-init; this issue is also fixed by not attempting to load the GSC FW after an error.

2024-08-31bcachefs: Revert lockless buffered IO pathKent Overstreet
We had a report of data corruption on nixos when building installer images. https://github.com/NixOS/nixpkgs/pull/321055#issuecomment-2184131334 It seems that writes are being dropped, but only when issued by QEMU, and possibly only in snapshot mode. It's undetermined if it's write calls are being dropped or dirty folios. Further testing, via minimizing the original patch to just the change that skips the inode lock on non appends/truncates, reveals that it really is just not taking the inode lock that causes the corruption: it has nothing to do with the other logic changes for preserving write atomicity in corner cases. It's also kernel config dependent: it doesn't reproduce with the minimal kernel config that ktest uses, but it does reproduce with nixos's distro config. Bisection the kernel config initially pointer the finger at page migration or compaction, but it appears that was erroneous; we haven't yet determined what kernel config option actually triggers it. Sadly it appears this will have to be reverted since we're getting too close to release and my plate is full, but we'd _really_ like to fully debug it. My suspicion is that this patch is exposing a preexisting bug - the inode lock actually covers very little in IO paths, and we have a different lock (the pagecache add lock) that guards against races with truncate here.
