[PATCH 3/6] drm/ttm: Change the meaning of resource->start from pfn to bytes
Somalapuram Amaranath
Amaranath.Somalapuram at amd.com
Wed Feb 8 09:01:03 UTC 2023
Change resource->start from pfn to bytes to
allow allocating objects smaller than a page.
Change all DRM drivers using ttm_resource start and size pfn to bytes.
Change amdgpu_res_first() cur->start, cur->size from pfn to bytes.
Replacing ttm_resource resource->start field with cursor.start.
Change amdgpu_gtt_mgr_new() allocation from pfn to bytes.
