Other than the sw fallback, no. The software rendering fallback in the intel driver is pretty slick. The gallium driver has nothing like that, correct?

Not sure though what you mean by pretty slick, in my experience it is usually useless due to glacial performance (though I guess maybe it's better thanks to UMA compared to old radeons). FYI, the old failover module was actually capable of switching between a hardware driver and softpipe in the middle of rendering. It should be possible to implement something similar for i915g, though it might be a lot of work. |
