The libdrm/mesa design isn't the hard part, we have that even as a helper for etnaviv and all those drivers. Being inconsistent here is a think more a nuisance for integrators, who might want to sandbox gpu clients real hard and really want to know what access rights they need to give out. But then we have much, much bigger fish to fry from a cross-driver consistency pov, so *shrug*. Just feels somewhat silly we can't even get agreement or some kind of consistent plan on something fairly simple like this. -Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
