In some APUs, the bo type of GART page table is ttm_bo_type_sg. Those type BOs is released by bo->delayed_delete which is added in ttm_device->wq, not released immediately.To make sure all the ttm_resource is released before ttm_resource_manager is finilized, drain the workqueue in ttm_device. v2: move drain_workqueue to amdgpu_ttm.c Fixes:d99fbd9aab62 ("drm/ttm: Always take the bo delayed cleanup path for imported bos") Suggested-by: Christian König <[email protected]> Signed-off-by: Asher Song <[email protected]>
