Also there is no need to force other module to call a ttm function just to eventually call vram_mgr functions. v2: pass adev's vram_mgr instead of adev Reviewed-by: Christian König Signed-off-by: Nirmoy Das Signed-off-by: Alex Deucher --- diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c index 0311d79..06d0750 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c @@ -298,7 +298,6 @@ static void amdgpu_cs_get_threshold_for_moves(struct amdgpu_device *adev, { s64 time_us, increment_us; u64 free_vram, total_vram, used_vram; - struct ttm_resource_manager *vram_man = ttm_manager_type(&adev->mman.bdev, TTM_PL_VRAM); /* Allow a maximum of 200 accumulated ms.
