The compatible should be the first actual device that is part of the xx series, and newer IP should claim to be compatible with their own version plus the original one (if they are possible to use with the same exact programming model and only need extra code to deal with extensions). That way you'll also have a way to tell them apart in the driver if you can't derive it out of register contents, etc. -Olof _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
