2018-08-27drm/amdgpu: use bulk moves for efficient VM LRU handling (v6)Huang Rui
I continue to work for bulk moving that based on the proposal by Christian. Background: amdgpu driver will move all PD/PT and PerVM BOs into idle list. Then move all of them on the end of LRU list one by one. Thus, that cause so many BOs moved to the end of the LRU, and impact performance seriously. Then Christian provided a workaround to not move PD/PT BOs on LRU with below patch: Commit 0bbf32026cf5ba41e9922b30e26e1bed1ecd38ae ("drm/amdgpu: band aid validating VM PTs") However, the final solution should bulk move all PD/PT and PerVM BOs on the LRU instead of one by one. Whenever amdgpu_vm_validate_pt_bos() is called and we have BOs which need to be validated we move all BOs together to the end of the LRU without dropping the lock for the LRU. While doing so we note the beginning and end of this block in the LRU list. Now when amdgpu_vm_validate_pt_bos() is called and we don't have anything to do, we don't move every BO one by one, but instead cut the LRU list into pieces so that we bulk move everything to the end in just one operation.
