[Philip Yang <Philip.Yang@amd.com>]

To reduce multiple queues switch latency, move user queues MQD to HBM,
and map on GART with mtype RW.

v2: patch 4 GART mapping use MC address, vram_base_offset + physical address

Philip Yang (4):
  drm/amdkfd: Bind gfx9 MQD in GART with mtype RW
  drm/amdkfd: Add domain parameter to alloc kernel BO
  drm/amdkfd: Move gfx9 MQD to VRAM domain
  drm/amdkfd: Map VRAM MQD on GART
