Author: Lucas Stach <l.st...@pengutronix.de> Date: Mon Oct 16 20:03:39 2023 +0200 etnaviv: track resource sharing Track if resources are shared outside of the screen, which means changes to the resource must be visible to the external observers after a flush and the resource might be manipulated by other agents than the contexts from the screen.
