I have no idea what the rules should be here. Or how it should interact with error. Should we just try the "drm: Track framebuffer references at the point of assignment" approach to simplify the rules (at least from my perspective)? The problem with that patch is sorting out the state duplication done in a couple of drivers and figuring out if they are transferring ownership or not. -Chris _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
