2025-08-04drm/amdgpu: Effective health check before resetCe Sun
Move amdgpu_device_health_check into amdgpu_device_gpu_recover to ensure that if the device is present can be checked before reset The reason is: 1.During the dpc event, the device where the dpc event occurs is not present on the bus 2.When both dpc event and ATHUB event occur simultaneously,the dpc thread holds the reset domain lock when detecting error,and the gpu recover thread acquires the hive lock.The device is simultaneously in the states of amdgpu_ras_in_recovery and occurs_dpc,so gpu recover thread will not go to amdgpu_device_health_check.It waits for the reset domain lock held by the dpc thread, but dpc thread has not released the reset domain lock.In the dpc callback slot_reset,to obtain the hive lock, the hive lock is held by the gpu recover thread at this time.So a deadlock occurred Signed-off-by: Ce Sun <cesun102@amd.com> Reviewed-by: Tao Zhou <tao.zhou1@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2025-08-04drm/xe/devcoredump: Defer devcoredump initialization during probeBalasubramani Vivekanandan
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.

2025-08-04drm/panel: novatek-nt35560: Fix invalid return valueBrigham Campbell
Fix bug in nt35560_set_brightness() which causes the function to erroneously report an error. mipi_dsi_dcs_write() returns either a negative value when an error occurred or a positive number of bytes written when no error occurred. The buggy code reports an error under either condition.

2025-08-04drm: panel: add support for Samsung AMS561RA01 panel with S6E8AA5X01 controllerKaustabh Chakraborty
Samsung AMS561RA01 is an AMOLED panel, using the Samsung S6E8AA5X01 MIPI DSI controller. Implement a basic panel driver for such panels. The driver also initializes a backlight device, which works by changing the panel's gamma values and aid brightness levels appropriately, with the help of look-up tables acquired from downstream kernel sources.

2025-08-04drm/xe/vf: Rebase exec queue parallel commands during migration recoveryTomasz Lis
Parallel exec queues have an additional command streamer buffer which holds a GGTT reference to data within context status.

2025-08-04drm/xe/vf: Refresh utilization buffer during migration recoveryTomasz Lis
The WA buffer we use to capture context utilization contains GGTT references. This means its instructions have to be either fixed or re-emitted during VF post-migration recovery. This patch adds re-emitting content of the utilization WA BB during the recovery. The way we write to vram requires scratch buffer to be used before the whole block is memcopied. We are re-using a scratch buffer introduced in earlier part of the recovery. This is not a performance optimization, but a necessity to avoid creating dependencies between locks. v2: Notable rebase after "Prepare WA BB setup for more users" patch v3: Added error propagation Signed-off-by: Tomasz Lis <tomasz.lis@intel.com> Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Michal Winiarski <michal.winiarski@intel.com> Reviewed-by: Michal Winiarski <michal.winiarski@intel.com> Link: https://lore.kernel.org/r/20250802031045.1127138-8-tomasz.lis@intel.com Signed-off-by: Michał Winiarski <michal.winiarski@intel.com>
