We're not doing CS page flips w/ sprites currently, so I think you could drop the sprite bits too. Actually, now that I think about it, do we need any bits enabled here? i915_gem_execbuffer_wait_for_flips() is gone, so AFAICS GT no longer needs to know when page flips complete. -- Ville Syrjälä Intel OTC _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
