It isn't clear to me if it is saying: - All igfx devices has the graphics base at 0x5c, a few have it in other places, too (which doesn't matter, we can use 0x5c anyway), or - Most igfx devices have the graphics base at 0x5c, some don't, and we hope and pray we're not on one of those systems because we're not checking. I assume it is the former, but it really needs to be phrased better. -hpa _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
