2025-12-11drm/xe/vf: Reset recovery_queued after issuing RESFIX_STARTSatyanarayana K V P
During VF_RESTORE or VF_RESUME, the GuC sends a migration interrupt and clears the RESFIX_START marker. If migration or resume occurs before the VF issues its own RESFIX_START, VF KMD may receive two back-to-back migration interrupts. VF then sends RESFIX_START to indicate the beginning of fixups and RESFIX_DONE to mark completion. However, the second RESFIX_START fails because the GuC is already in the RUNNING state. Clear the recovery_queued flag after sending a RESFIX_START message to ignore duplicated IRQs seen before we start actual recovery. This ensures the state is reset only after the fixup process begins, avoiding redundant work item queuing.

2025-12-11drm/bridge: ti-sn65dsi83: protect device resources on unplugLuca Ceresoli
To support hot-unplug of this bridge we need to protect access to device resources in case sn65dsi83_remove() happens concurrently to other code. Some care is needed for the case when the unplug happens before sn65dsi83_atomic_disable() has a chance to enter the critical section (i.e. a successful drm_bridge_enter() call), which occurs whenever the hardware is removed while the display is active. When that happens, sn65dsi83_atomic_disable() in unable to release the resources taken by sn65dsi83_atomic_pre_enable(). To ensure those resources are released exactly once on device removal: * move the code to release them to a dedicated function * register that function when the resources are taken in sn65dsi83_atomic_pre_enable() * if sn65dsi83_atomic_disable() happens before sn65dsi83_remove() (typical non-hot-unplug case): * sn65dsi83_atomic_disable() can enter the critical section (drm_bridge_enter() returns 0) -> it releases and executes the devres action * if sn65dsi83_atomic_disable() happens after sn65dsi83_remove() (typical hot-unplug case): * sn65dsi83_remove() -> drm_bridge_unplug() prevents sn65dsi83_atomic_disable() from entering the critical section (drm_bridge_enter() returns nonzero), so sn65dsi83_atomic_disable() cannot release and execute the devres action * the devres action is executed at the end of sn65dsi83_remove() Reviewed-by: Maxime Ripard <mripard@kernel.org> Link: https://patch.msgid.link/20251112-drm-bridge-atomic-vs-remove-v3-2-85db717ce094@bootlin.com Signed-off-by: Luca Ceresoli <luca.ceresoli@bootlin.com>

2025-12-11drm/me/gsc: mei interrupt top half should be in irq disabled contextJunxiao Chang
MEI GSC interrupt comes from i915 or xe driver. It has top half and bottom half. Top half is called from i915/xe interrupt handler. It should be in irq disabled context. With RT kernel(PREEMPT_RT enabled), by default IRQ handler is in threaded IRQ. MEI GSC top half might be in threaded IRQ context. generic_handle_irq_safe API could be called from either IRQ or process context, it disables local IRQ then calls MEI GSC interrupt top half.

2025-12-11drm/i915/display: Detect AuxCCS support via display parent interfaceTvrtko Ursulin
Whether AuxCCS can be properly supported depends on the support both from the display side and non-display side of the driver. Let us therefore allow for the non-display part to be queried via the display parent interface. The new interface replaces the HAS_AUX_CCS macro and we also remove the FIXME from skl_universal_plane_create since now the xe will not advertise the AuxCCS caps to start with so they do not need to be removed after enumeration. Also, by removing this build specific FIXME we come a step closer to fully de-coupling display and non-display. The existing HAS_AUX_CCS gets renamed to HAS_AUX_DIST since it is still required for determining the need for PLANE_AUX_DIST programming.

2025-12-10drm/amd/ras: Reduce stack usage in amdgpu_virt_ras_get_cper_records()Srinivasan Shanmugam
amdgpu_virt_ras_get_cper_records() was using a large stack array of ras_log_info pointers. This contributed to the frame size warning on this function. Replace the fixed-size stack array: struct ras_log_info *trace[MAX_RECORD_PER_BATCH]; with a heap-allocated array using kcalloc(). We free the trace buffer together with out_buf on all exit paths. If allocation of trace or out_buf fails, we return a generic RAS error code. This reduces stack usage and keeps the runtime behaviour unchanged. Fixes: stack frame size: 1112 bytes (limit: 1024) Cc: Tao Zhou <tao.zhou1@amd.com> Cc: Hawking Zhang <Hawking.Zhang@amd.com> Cc: Christian König <christian.koenig@amd.com> Cc: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Srinivasan Shanmugam <srinivasan.shanmugam@amd.com> Reviewed-by: Tao Zhou <tao.zhou1@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
