Chris, thoughts? As different machines favour different w/a, I think the issue is mostly timing related. It could be sequence of register writes, but we tried different orders early on. The next experiment I guess would be to insert small delays between each write to see if that helps. Or to write each register twice. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
