2024-10-30drm/panthor: Fix firmware initialization on systems with a page size > 4kBoris Brezillon
The system and GPU MMU page size might differ, which becomes a problem for FW sections that need to be mapped at explicit addresses since our PAGE_SIZE alignment might cover a VA range that's expected to be used for another section. Make sure we never map more than we need. Changes in v3: - Add R-bs Changes in v2: - Plan for per-VM page sizes so the MCU VM and user VM can have different pages sizes Fixes: 2718d91816ee ("drm/panthor: Add the FW logical block") Signed-off-by: Boris Brezillon <boris.brezillon@collabora.com> Reviewed-by: Steven Price <steven.price@arm.com> Reviewed-by: Liviu Dudau <liviu.dudau@arm.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241030150231.768949-1-boris.brezillon@collabora.com

2024-10-30nvme: module parameter to disable pi with offsetsKeith Busch
A recent commit enables integrity checks for formats the previous kernel versions registered with the "nop" integrity profile. This means namespaces using that format become unreadable when upgrading the kernel past that commit. Introduce a module parameter to restore the "nop" integrity profile so that storage can be readable once again. This could be a boot device, so the setting needs to happen at module load time.

2024-10-30ALSA: usb-audio: Add quirks for Dell WD19 dockJan Schär
The WD19 family of docks has the same audio chipset as the WD15. This change enables jack detection on the WD19. We don't need the dell_dock_mixer_init quirk for the WD19. It is only needed because of the dell_alc4020_map quirk for the WD15 in mixer_maps.c, which disables the volume controls. Even for the WD15, this quirk was apparently only needed when the dock firmware was not updated.

2024-10-30drm: zynqmp_dp: Add debugfs interface for compliance testingSean Anderson
Add a debugfs interface for exercising the various test modes supported by the DisplayPort controller. This allows performing compliance testing, or performing signal integrity measurements on a failing link. At the moment, we do not support sink-driven link quality testing, although such support would be fairly easy to add. Additionally, add some debugfs files for ignoring AUX errors and HPD events, as this can allow testing with equipment that cannot emulate a DPRX.

2024-10-30drm: zynqmp_dp: Add lockingSean Anderson
Add some locking to prevent the IRQ/workers/bridge API calls from stepping on each other's toes. This lock protects: - Non-atomic registers configuring the link. That is, everything but the IRQ registers (since these are accessed in an atomic fashion), and the DP AUX registers (since these don't affect the link). We also access AUX while holding this lock, so it would be very tricky to support. - Link configuration. This is effectively everything in zynqmp_dp which isn't read-only after probe time. So from next_bridge onward. This lock is designed to protect configuration changes so we don't have to do anything tricky. Configuration should never be in the hot path, so I'm not worried about performance.

2024-10-30xfs: fix finding a last resort AG in xfs_filestream_pick_agChristoph Hellwig
When the main loop in xfs_filestream_pick_ag fails to find a suitable AG it tries to just pick the online AG. But the loop for that uses args->pag as loop iterator while the later code expects pag to be set. Fix this by reusing the max_pag case for this last resort, and also add a check for impossible case of no AG just to make sure that the uninitialized pag doesn't even escape in theory.

2024-10-30xfs: Reduce unnecessary searches when searching for the best extentsChi Zhiling
Recently, we found that the CPU spent a lot of time in xfs_alloc_ag_vextent_size when the filesystem has millions of fragmented spaces. The reason is that we conducted much extra searching for extents that could not yield a better result, and these searches would cost a lot of time when there were millions of extents to search through. Even if we get the same result length, we don't switch our choice to the new one, so we can definitely terminate the search early. Since the result length cannot exceed the found length, when the found length equals the best result length we already have, we can conclude the search. We did a test in that filesystem: [root@localhost ~]# xfs_db -c freesp /dev/vdb from to extents blocks pct 1 1 215 215 0.01 2 3 994476 1988952 99.99 Before this patch: 0) | xfs_alloc_ag_vextent_size [xfs]() { 0) * 15597.94 us | } After this patch: 0) | xfs_alloc_ag_vextent_size [xfs]() { 0) 19.176 us | } Signed-off-by: Chi Zhiling <chizhiling@kylinos.cn> Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Carlos Maiolino <cem@kernel.org>

2024-10-30accel/ivpu: Defer MMU root page table allocationKarol Wachowski
Defer root page table allocation and unify context init/fini functions. Move allocation of the root page table from the file_priv_open function to perform a lazy allocation approach during ivpu_bo_pin(). By doing so, we avoid the overhead of allocating page tables for simple operations like GET_PARAM that do not require them. Additionally, the MMU context descriptor table initialization has been moved to the ivpu_mmu_context_map_page function. This change streamlines the process and ensures that the descriptor table is only initialized when it is actually needed. Refactor init/fini functions to remove redundant code and make the context management more straightforward. Overall, these changes lead to a reduction in the time taken by the file descriptor open operation, as the costly root page table allocation is now avoided for operations that do not require it.
