drm/amdkfd: Not restore userptr buffer if kfd process has been removed

When kfd process has been terminated not restore userptr buffer after mmu notifier invalidates a range. Signed-off-by: Xiaogang Chen Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: Fix an eviction fence leak

Only creating a new reference for each process instead of each VM. Fixes: 9a1c1339abf9 ("drm/amdkfd: Run restore_workers on freezable WQs") Suggested-by: Felix Kuehling Signed-off-by: Lang Yu Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: remove amdgpu_pin_restricted()

2024-09-18T20:15:09Z

We haven't used the functionality to pin BOs in a certain range at all while the driver existed. Just nuke it. Signed-off-by: Christian König Acked-by: Lijo Lazar Signed-off-by: Alex Deucher

drm/amdgpu: fix a race in kfd_mem_export_dmabuf()

2024-09-10T17:44:30Z

Using drm_gem_prime_handle_to_fd() to set dmabuf up and insert it into descriptor table, only to have it looked up by file descriptor and remove it from descriptor table is not just too convoluted - it's racy; another thread might have modified the descriptor table while we'd been going through that song and dance. Switch kfd_mem_export_dmabuf() to using drm_gem_prime_handle_to_dmabuf() and leave the descriptor table alone... Reviewed-by: Felix Kuehling Signed-off-by: Al Viro Signed-off-by: Alex Deucher

drm/amdkfd: Ensure user queue buffers residency

2024-07-23T21:42:54Z

Add atomic queue_refcount to struct bo_va, return -EBUSY to fail unmap BO from the GPU if the bo_va queue_refcount is not zero. Create queue to increase the bo_va queue_refcount, destroy queue to decrease the bo_va queue_refcount, to ensure the queue buffers mapped on the GPU when queue is active.

drm/amdkfd: Refactor queue wptr_bo GART mapping

2024-07-23T21:35:04Z

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.

Change amdgpu_amdkfd_bo_mapped_to_dev to use drm_priv as parameter instead of adev, to support spatial partition. This is only used by CRIU checkpoint restore now. No functional change. Signed-off-by: Philip Yang Reviewed-by: Felix Kuehling Acked-by: Christian König Signed-off-by: Alex Deucher

drm/amdkfd: simplify APU VRAM handling

2024-05-29T18:48:30Z

With commit 89773b85599a ("drm/amdkfd: Let VRAM allocations go to GTT domain on small APUs") big and small APU "VRAM" handling in KFD was unified. Since AMD_IS_APU is set for both big and small APUs, we can simplify the checks in the code. v2: clean up a few more places (Lang) Acked-by: Felix Kuehling Reviewed-by: Lang Yu Signed-off-by: Alex Deucher
