Hi Christian, We seem to be hitting a new issue in ttm_bo_move_sync_cleanup(), due to passing a NULL fence, and I guess with some recent changes this is now blowing up in at least dma_resv_add_fence(). Question is how should we handle this? Should we add a special case in ttm_bo_move_accel_cleanup() in case of NULL fence, and then maybe just always call ttm_bo_wait_free_node() and also skip the add_fence? Or maybe this case should rather be moved into the driver, and handled with something along the lines of ttm_bo_move_null()? Any thoughts here?
