drm/ttm: update bulk move object of ghost BO
[Why] Ghost BO is released with non-empty bulk move object. There is a warning trace: WARNING: CPU: 19 PID: 1582 at ttm/ttm_bo.c:366 ttm_bo_release+0x2e1/0x2f0 [amdttm] Call Trace: amddma_resv_reserve_fences+0x10d/0x1f0 [amdkcl] amdttm_bo_put+0x28/0x30 [amdttm] amdttm_bo_move_accel_cleanup+0x126/0x200 [amdttm] amdgpu_bo_move+0x1a8/0x770 [amdgpu] ttm_bo_handle_move_mem+0xb0/0x140 [amdttm] amdttm_bo_validate+0xbf/0x100 [amdttm] [How] The resource of ghost BO should be moved to LRU directly, instead of using bulk move. The bulk move object of ghost BO should set to NULL before function ttm_bo_move_to_lru_tail_unlocked. v2: set bulk move to NULL manually if no resource associated with ghost BO Fixed: 5b951e487fd6bf5f ("drm/ttm: fix bulk move handling v2") Signed-off-by: ZhenGuo Yin <zhenguo.yin@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Christian König <christian.koenig@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220906084619.2545456-1-zhenguo.yin@amd.com
