From 691191a2f458e0176414cb5b3993b0c018cdc58c Mon Sep 17 00:00:00 2001 From: YuBiao Wang Date: Tue, 17 Aug 2021 17:36:33 +0800 Subject: [PATCH] drm/amd/amdgpu:flush ttm delayed work before cancel_sync [Why] In some cases when we unload driver, warning call trace will show up in vram_mgr_fini which claims that LRU is not empty, caused by the ttm bo inside delay deleted queue. [How] We should flush delayed work to make sure the delay deleting is done.
