2025-08-06drm/amdkfd: Destroy KFD debugfs after destroy KFD wqAmber Lin1-1/+1
Since KFD proc content was moved to kernel debugfs, we can't destroy KFD debugfs before kfd_process_destroy_wq. Move kfd_process_destroy_wq prior to kfd_debugfs_fini to fix a kernel NULL pointer problem. It happens when /sys/kernel/debug/kfd was already destroyed in kfd_debugfs_fini but kfd_process_destroy_wq calls kfd_debugfs_remove_process. This line debugfs_remove_recursive(entry->proc_dentry); tries to remove /sys/kernel/debug/kfd/proc/<pid> while /sys/kernel/debug/kfd is already gone. It hangs the kernel by kernel NULL pointer.

2025-08-04drm/amd/display: fix a Null pointer dereference vulnerabilitySiyang Liu1-9/+10
[Why] A null pointer dereference vulnerability exists in the AMD display driver's (DC module) cleanup function dc_destruct(). When display control context (dc->ctx) construction fails (due to memory allocation failure), this pointer remains NULL. During subsequent error handling when dc_destruct() is called, there's no NULL check before dereferencing the perf_trace member (dc->ctx->perf_trace), causing a kernel null pointer dereference crash. [How] Check if dc->ctx is non-NULL before dereferencing.

2025-08-04drm/amd/display: Add primary plane to commits for correct VRR handlingMichel Dänzer1-0/+9
amdgpu_dm_commit_planes calls update_freesync_state_on_stream only for the primary plane. If a commit affects a CRTC but not its primary plane, it would previously not trigger a refresh cycle or affect LFC, violating current UAPI semantics. Fixes e.g. atomic commits affecting only the cursor plane being limited to the minimum refresh rate. Don't do this for the legacy cursor ioctls though, it would break the UAPI semantics for those.

2025-08-04drm/xe/devcoredump: Defer devcoredump initialization during probeBalasubramani Vivekanandan2-4/+10
Doing devcoredump initializing before GT though look harmless, it leads to problem during driver unbind. Because of this order, GT/Engine release functions will be called before xe devcoredump release function (xe_driver_devcoredump_fini) leading to the following kernel crash[1] because the devcoredump functions might still use GT/Engine datastructures after those are freed. The following crash is observed while running the IGT xe_wedged@wedged-at-any-timeout. The test forces a wedged state by submitting a workload which hangs. Then does a unbind/rebind of the driver to recover from the wedged state. The hanged workload leads to a devcoredump. The following crash is noticed when the devcoredump capture races with the driver unbind. During driver unbind, the release function hw_engine_fini() will be called which assigns NULL to hwe->gt. But the same data structure is accessed during the coredump capture in the function xe_engine_snapshot_print by reading snapshot->hwe->gt. With this patch, we make sure the devcoredump is stopped before deinitializing the core driver functions.
