drm/amdgpu: Drop 'fence' check in 'to_amdgpu_amdkfd_fence()'

2024-01-05T21:10:43+00:00

Return value of container_of(...) can't be null, so null check is not required for 'fence'. Hence drop its NULL check. Fixes the below: drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd_fence.c:93 to_amdgpu_amdkfd_fence() warn: can 'fence' even be NULL?

drm/amdkfd: add svm_bo reference for eviction fence

2021-04-21T01:49:22+00:00

[why] As part of the SVM functionality, the eviction mechanism used for SVM_BOs is different. This mechanism uses one eviction fence per prange, instead of one fence per kfd_process. [how] A svm_bo reference to amdgpu_amdkfd_fence to allow differentiate between SVM_BO or regular BO evictions. This also include modifications to set the reference at the fence creation call.

drm/amdgpu: Add KFD eviction fence

2018-02-07T01:32:35+00:00

This fence is used by KFD to keep memory resident while user mode queues are enabled. Trying to evict memory will trigger the enable_signaling callback, which starts a KFD eviction, which involves preempting user mode queues before signaling the fence. There is one such fence per process. v2: * Grab a reference to mm_struct * Dereference fence after NULL check * Simplify fence release, no need to signal without anyone waiting * Added signed-off-by Harish, who is the original author of this code v3: * update MAINTAINERS file * change amd_kfd_ prefix to amdkfd_ * remove useless initialization of variable to NULL v4: * set amdkfd_fence_ops to be static * Suggested by: Fengguang Wu Signed-off-by: Harish Kasiviswanathan Signed-off-by: Felix Kuehling Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay
