[PATCH v5 0/6] Best effort contiguous VRAM allocation

[Philip Yang]

This patch series implement new KFD memory alloc flag for best effort contiguous
VRAM allocation, to support peer direct access RDMA device with limited scatter-gather
dma capability.

v2: rebase on patch ("drm/amdgpu: Modify the contiguous flags behaviour")
    to avoid adding the new GEM flag

v3: add patch 2 to handle sg segment size limit (Christian)

v4: remove the buddy block size limit from vram mgr because sg table creation already
    remove the limit, and resource uses u64 to handle block start, size (Christian)

v5: remove patch 7 which is not for upstream, add AMDGPU prefix to the macro name.

Philip Yang (6):
  drm/amdgpu: Support contiguous VRAM allocation
  drm/amdgpu: Handle sg size limit for contiguous allocation
  drm/amdgpu: Evict BOs from same process for contiguous allocation
  drm/amdkfd: Evict BO itself for contiguous allocation
  drm/amdkfd: Increase KFD bo restore wait time
  drm/amdkfd: Bump kfd version for contiguous VRAM allocation
