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.

Philip Yang (6):
  drm/amdgpu: Support contiguous VRAM 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
