[PATCH v5 0/6] drm/amdkfd: Move gfx9 MQD to HBM

[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.

v5:
 - patch 1 update commit message
 - patch 5 separate GART alloc helpers
 - patch 6 use resource cursor to handle GART entries

v4:
 - patch 1 remove the executable bit change, cc stable
 - patch 5 move GART helper functions to amdgpu_gtt_mgr.c
 - add patch 6 to update MQD GART mapping using resource cursor

v3:
 - add patch 1 to fix gfx9 mtype update bug
 - patch 2 use ASIC specific mtype
 - patch 5 use drm mm to alloc GART entries and store in mqd obj

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

Philip Yang (6):
  drm/amdgpu: Fix gfx9 update PTE mtype flag
  drm/amdkfd: Bind MQD in GART with mtype RW
  drm/amdkfd: Add domain parameter to alloc kernel BO
  drm/amdkfd: Move gfx9 MQD to VRAM domain
  drm/amdgpu: Add helper to alloc GART entries
  drm/amdkfd: Map VRAM MQD on GART
