From 274840e544225657fbca4f12efa1ee55474bb800 Mon Sep 17 00:00:00 2001 From: Felix Kuehling Date: Tue, 9 Jul 2019 19:09:42 -0400 Subject: drm/ttm: Add release_notify callback to ttm_bo_driver MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This notifies the driver that a BO is about to be released. Releasing a BO also invokes the move_notify callback from ttm_bo_cleanup_memtype_use, but that happens too late for anything that would add fences to the BO and require a delayed delete.
