Names RP0, and RP1, while matching the spec do not do this. They have no meaning to anyone not well versed in the spec. When one wants to find out min/max, or rp0/rp1, they'd always have to do a conversion from one to the other by looking at the code (unless we added a #define or something to alias it). My point really is, it's almost always more useful to know MIN and MAX, and if you must figure out if it's RP0, or RP1, then go back to the code to find it. Still would like an answer about RPe... -- Ben Widawsky, Intel Open Source Technology Center _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
