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)
Philip Yang (7):
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/amdgpu: Skip dma map resource for null RDMA device
drm/amdkfd: Bump kfd version for contiguous VRAM allocation
