Broadwater snafu? Does the w/a thing actually work correctly for masked registers? It look to use rmw even for masked registers and IIRC some masked registers return 0xffff for the mask when read. I lost track of the values and masks being passed around before I got down that deep so can't immediatly see if the code is guaranteed to set only the expected mask bit(s) for the write. -- = Ville Syrj=E4l=E4 Intel _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
