2025-04-10drm/xe: Add page queue multiplierMatthew Brost1-2/+9
For an unknown reason the math to determine the PF queue size does is not correct - compute UMD applications are overflowing the PF queue which is fatal. A multippier of 8 fixes the problem. Fixes: 3338e4f90c14 ("drm/xe: Use topology to determine page fault queue size") Cc: stable@vger.kernel.org Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Jagmeet Randhawa <jagmeet.randhawa@intel.com> Link: https://lore.kernel.org/r/20250408155915.78770-1-matthew.brost@intel.com
2025-04-10drm/xe: remove unused LE_COSShuicheng Lin1-1/+0
The LE_COS definition missed passing the value parameter to REG_FIELD_PREP. This didn't cause build errors because the entire macro was unused. The value for this field is universally "0" for every MOCS entry on the old Xe_LP platforms, and the whole field has been removed from Xe_HP onward. Just delete the line so that we don't have an unused definition.

2025-04-08drm/amdgpu: Fix display freezing issue when resizing appsArvind Yadav2-0/+6
The display is freezing because the amdgpu_userq_wait_ioctl() is waiting for a non-user queue fence(specifically, the PT update fence). RootCause: The resume_work is initiated by both amdgpu_userq_suspend and amdgpu_userqueue_ensure_ev_fence at same time. The amdgpu_userq_suspend signals a dma-fence and subsequently triggers the resume_work, which is intended to replace the existing fence by creating new dma-fence. However, following this, the amdgpu_userqueue_ensure_ev_fence schedules another resume_work that generates a new dma-fence, thereby replacing the one created by amdgpu_userq_suspend. Consequently, the original fence will never be signaled.

2025-04-08drm/amdgpu: fix the memleak caused by fence not releasedArvind Yadav1-12/+16
Encountering a taint issue during the unloading of gpu_sched due to the fence not being released/put. In this context, amdgpu_vm_clear_freed is responsible for creating a job to update the page table (PT). It allocates kmem_cache for drm_sched_fence and returns the finished fence associated with job->base.s_fence. In case of Usermode queue this finished fence is added to the timeline sync object through amdgpu_gem_update_bo_mapping, which is utilized by user space to ensure the completion of the PT update.
