drm/amdgpu: Implement VRAM wipe on release

2019-08-02T15:18:32Z

Wipe VRAM memory containing sensitive data when moving or releasing BOs. Clearing the memory is pipelined to minimize any impact on subsequent memory allocation latency. Use of a poison value should help debug future use-after-free bugs. When moving BOs, the existing ttm_bo_pipelined_move ensures that the memory won't be reused before being wiped. When releasing BOs, the BO is fenced with the memory fill operation, which results in queuing the BO for a delayed delete. v2: Move amdgpu_amdkfd_unreserve_memory_limit into amdgpu_bo_release_notify so that KFD can use memory that's still being cleared in the background Signed-off-by: Felix Kuehling Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: Create helper to clear AMDGPU_GEM_CREATE_CPU_GTT_USWC

2019-07-31T04:22:48Z

Move the logic to clear AMDGPU_GEM_CREATE_CPU_GTT_USWC in amdgpu_bo_do_create into standalone helper so it can be reused in other functions. v4: Switch to return bool. v5: Fix typos. Signed-off-by: Andrey Grodzovsky Acked-by: Michel Dänzer Signed-off-by: Alex Deucher

drm/amdgpu: stop removing BOs from the LRU v3

This avoids OOM situations when we have lots of threads submitting at the same time. v3: apply this to the whole driver, not just CS Signed-off-by: Christian König Reviewed-by: Chunming Zhou Tested-by: Pierre-Eric Pelloux-Prayer Signed-off-by: Alex Deucher

drm/amdgpu: XGMI pstate switch initial support

Driver vote low to high pstate switch whenever there is an outstanding XGMI mapping request. Driver vote high to low pstate when all the outstanding XGMI mapping is terminated. Signed-off-by: shaoyunl Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: revert "XGMI pstate switch initial support"

2019-03-21T19:05:01Z

This reverts commit 9b638f9751308ae3ae8f28e0c6e9decffd97f5f9. Adding this to the mapping is complete nonsense and the whole implementation looks racy. This patch wasn't thoughtfully reviewed and should be reverted for now. Signed-off-by: Christian König Acked-by: Liu, Shaoyun Signed-off-by: Alex Deucher
