linux.git/drivers/gpu/drm/amd/amdgpu/amdgpu_vram_mgr.c, branch v5.14 Linux kernel source tree drm/amdgpu: Set ttm caching flags during bo allocation 2021-07-01T04:05:12+00:00 Oak Zeng Oak.Zeng@amd.com 2021-06-28T22:53:38+00:00 8dbe43e99f0f62fc4f829b4fedc5d628a329fc38 The ttm caching flags (ttm_cached, ttm_write_combined etc) are used to determine a buffer object's mapping attributes in both CPU page table and GPU page table (when that buffer is also accessed by GPU). Currently the ttm caching flags are set in function amdgpu_ttm_io_mem_reserve which is called during DRM_AMDGPU_GEM_MMAP ioctl. This has a problem since the GPU mapping of the buffer object (ioctl DRM_AMDGPU_GEM_VA) can happen earlier than the mmap time, thus the GPU page table update code can't pick up the right ttm caching flags to decide the right GPU page table attributes. This patch moves the ttm caching flags setting to function amdgpu_vram_mgr_new - this function is called during the first step of a buffer object create (eg, DRM_AMDGPU_GEM_CREATE) so the later both CPU and GPU mapping function calls will pick up this flag for CPU/GPU page table set up. v2: rebase (Alex) Signed-off-by: Oak Zeng <Oak.Zeng@amd.com> Suggested-by: Christian Koenig <Christian.Koenig@amd.com> Reviewed-by: Christian Koenig <Christian.Koenig@amd.com> Reviewed-by: Feifei Xu <Feifei.Xu@amd.com> Tested-by: Po Huang <Po.Huang@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> 
The ttm caching flags (ttm_cached, ttm_write_combined etc) are
used to determine a buffer object's mapping attributes in both
CPU page table and GPU page table (when that buffer is also
accessed by GPU). Currently the ttm caching flags are set in
function amdgpu_ttm_io_mem_reserve which is called during
DRM_AMDGPU_GEM_MMAP ioctl. This has a problem since the GPU
mapping of the buffer object (ioctl DRM_AMDGPU_GEM_VA) can
happen earlier than the mmap time, thus the GPU page table
update code can't pick up the right ttm caching flags to
decide the right GPU page table attributes.

This patch moves the ttm caching flags setting to function
amdgpu_vram_mgr_new - this function is called during the
first step of a buffer object create (eg, DRM_AMDGPU_GEM_CREATE)
so the later both CPU and GPU mapping function calls will
pick up this flag for CPU/GPU page table set up.
