2025-05-23drm: convert many bridge drivers from devm_kzalloc() to ↵Luca Ceresoli
devm_drm_bridge_alloc() API devm_drm_bridge_alloc() is the new API to be used for allocating (and partially initializing) a private driver struct embedding a struct drm_bridge. For many drivers having a simple code flow in the probe function, this commit does a mass conversion automatically with the following semantic patch. The changes have been reviewed manually for correctness as well as to find any false positives. The patch has been applied with the explicit exclusion of bridge/panel.c, handled by a separate patch. After applying the semantic patch, manually fixed these issues: - 4 drivers need ERR_CAST() instead of PTR_ERR() as the function calling devm_drm_bridge_alloc() returns a pointer - re-added empty lines and comments that the script had removed but that should stay @@ type T; identifier C; identifier BR; expression DEV; expression FUNCS; @@ -T *C; +T *C; ...

2025-05-23drm/xe/guc: Make creation of SLPC debugfs files conditionalAradhya Bhatia
Platforms that do not support SLPC are exempted from the GuC PC support. The GuC PC does not get initialized, and neither do its BOs get created. This causes a problem because the GuC PC debugfs file is still being created. Whenever the file is attempted to read, it causes a NULL pointer dereference on the supposed BO of the GuC PC. So, make the creation of SLPC debugfs files conditional to when SLPC features are supported.

Static analysis shows that pointer "svms" cannot be NULL because it points to the object "struct svm_range_list". Remove the extra NULL check. It is meaningless and harms the readability of the code. In the function svm_range_get_info() there is no possibility of failure. Therefore, the caller of the function svm_range_get_info() does not need a return value. Change the function svm_range_get_info() return type from "int" to "void". Since the function svm_range_get_info() has a return type of "void".

2025-05-22drm/scheduler: signal scheduled fence when kill jobLin.Cao
When an entity from application B is killed, drm_sched_entity_kill() removes all jobs belonging to that entity through drm_sched_entity_kill_jobs_work(). If application A's job depends on a scheduled fence from application B's job, and that fence is not properly signaled during the killing process, application A's dependency cannot be cleared. This leads to application A hanging indefinitely while waiting for a dependency that will never be resolved. Fix this issue by ensuring that scheduled fences are properly signaled when an entity is killed, allowing dependent applications to continue execution.

2025-05-22drm/xe/vf: Fail migration recovery if fixups needed but platform not supportedTomasz Lis
The post-migration recovery needs to be fully implemented for a specific platform in order to make continuation of workloads possible. New platforms introduce changes which affect the recovery procedure, and without a clear verification of support this leads to errors with no straight forward error message explaining the cause. This patch fixes that issue - it introduces a message to be logged when the current driver is known to not support the current platform. Wedging the driver immediately also decreases the amount of additional errors which would come afterwards if the driver continued operation. v2: Show the message during probe as well as during recovery; do not perform any recovery steps if the recovery is bound to fail v3: Use SRIOV-specific logging, fix typos v4: XE_DEBUG_SRIOV to XE_DEBUG check switch, to make testing more straightforward Signed-off-by: Tomasz Lis <tomasz.lis@intel.com> Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Michał Winiarski <michal.winiarski@intel.com> Reviewed-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Acked-by: Michał Winiarski <michal.winiarski@intel.com> Signed-off-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Link: https://lore.kernel.org/r/20250519230035.3143966-1-tomasz.lis@intel.com

2025-05-22drm/i915/dp_mst: Work around Thunderbolt sink disconnect after ↵Imre Deak
SINK_COUNT_ESI read Due to a problem in the iTBT DP-in adapter's firmware the sink on a TBT link may get disconnected inadvertently if the SINK_COUNT_ESI and the DP_LINK_SERVICE_IRQ_VECTOR_ESI0 registers are read in a single AUX transaction. Work around the issue by reading these registers in separate transactions. The issue affects MTL+ platforms and will be fixed in the DP-in adapter firmware, however releasing that firmware fix may take some time and is not guaranteed to be available for all systems. Based on this apply the workaround on affected platforms. See HSD #13013007775. v2: Cc'ing Mika Westerberg.
