Author: Lucas Stach <[email protected]> Date: Mon Jun 26 12:25:08 2017 +0200 etnaviv: only flush resource to self if no scanout buffer exists Currently a resource flush may trigger a self resolve, even if a scanout buffer exists, but is up to date. If a scanout buffer exists we only ever want to flush the resource to the scanout buffer. This fixes a performance regression.
