[PATCH 00/13] *** per vm lru ***

[Chunming Zhou]

move implemenation from ttm to amdgpu driver. (suggested by Christian)
per-vm-lru is because of per-vm-bo, which has no chance to refresh lru, the nagtive effect is game performance isn't stable.
so all per-vm-bo should have a default order, every per-vm-bo has its priority, relying on its creation index.
When doing CS, if any normal bo is used, then all per-vm-bo should be used, so per-vm-bo prioirty >= normal bo priority.

Above is per-vm-lru starting point.



Chunming Zhou (13):
  ttm: abstruct evictable bo
  ttm: allow driver has own lru policy
  drm/amdgpu: add lru backend for amdgpu driver
  drm/amdgpu: init/fini vm lru
  drm/amdgpu: pass vm lru to buffer object
  drm/amdgpu: add amdgpu lru implementation
  drm/ttm: export ttm_bo_ref_bug
  drm/amdgpu: use RB tree instead of link list
  drm/amdgpu: add bo index counter
  drm/amdgpu: bulk move per vm bo
  ttm: export ttm_transfered_destroy
  drm/amdgpu: transferred bo doesn't use vm lru
  drm/amdgpu: free vm lru when vm fini
