Subject: [PATCH 0/8] do not store GPU address in TTM
Date: Mon, 17 Feb 2020 16:04:19 +0100	[thread overview]
Message-ID: <20200217150427.49994-1-nirmoy.das@amd.com> (raw)

With this patch series I am trying to remove GPU address dependency in
TTM and moving GPU address calculation to individual drm drivers.

I tested this patch series on qxl, bochs and amdgpu. Christian tested it on radeon HW.
It would be nice if someone test this for nouveau and vmgfx.

Nirmoy Das (8):
  drm/amdgpu: move ttm bo->offset to amdgpu_bo
  drm/radeon: don't use ttm bo->offset
  drm/vmwgfx: don't use ttm bo->offset
  drm/nouveau: don't use ttm bo->offset
  drm/qxl: don't use ttm bo->offset
  drm/vram-helper: don't use ttm bo->offset
  drm/bochs: use drm_gem_vram_offset to get bo offset
  drm/ttm: do not keep GPU dependent addresses
