This would theoretically change the behviour for i915 at least. Without the modifiers flag the kernel will pick the modifier for us based on the bo tiling, which in theory might not be what we wanted. But at least igt_fb should be fine with that. Maybe it would be better to just not pass the flags from the caller at all, and instead have __kms_addfb() check if the driver has modifiers or not and set the flag based on that? > > memset(&f, 0, sizeof(f)); > > -- > 2.17.1 > > _______________________________________________ > igt-dev mailing list > [email protected] > https://lists.freedesktop.org/mailman/listinfo/igt-dev -- Ville Syrjälä Intel _______________________________________________ Intel-gfx mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/intel-gfx
