drm/amdgpu: remove all KFD fences from the BO on release

2025-05-29T09:02:41+00:00

[ Upstream commit cb0de06d1b0afb2d0c600ad748069f5ce27730ec ] Remove all KFD BOs from the private dma_resv object. This prevents the KFD from being evict unecessarily when an exported BO is released.

drm/amdkfd: APIs to stop/start KFD scheduling

2024-08-21T02:07:28+00:00

Provide amdgpu_amdkfd_stop_sched() for amdgpu to stop KFD scheduling compute work on HIQ. amdgpu_amdkfd_start_sched() resumes the scheduling. When amdgpu_amdkfd_stop_sched is called, KFD will unmap queues from runlist. If users send ioctls to KFD to create queues, they'll be added but those queues won't be mapped to runlist (so not scheduled) until amdgpu_amdkfd_start_sched is called. v2: fix build (Alex) Signed-off-by: Amber Lin Signed-off-by: Alex Deucher

drm/amdkfd: Refactor queue wptr_bo GART mapping

2024-07-23T21:35:04+00:00

Add helper function kfd_queue_acquire_buffers to get queue wptr_bo reference from queue write_ptr if it is mapped to the KFD node with expected size. Add wptr_bo to structure queue_properties because structure queue is allocated after queue buffers are validated, then we can remove wptr_bo parameter from pqm_create_queue. Rename structure queue wptr_bo_gart to hold wptr_bo reference for GART mapping and umapping. Move MES wptr_bo_gart mapping to init_user_queue, the same location with queue ctx_bo GART mapping.
