The patch is correct, we do need to clear all 3 bits to restore progressive mode. However it would be better to add a new #define PIPECONF_INTERLACE_MASK (7 << 21) so that we do not confuse clearing all interlace bits with unsetting a particular mode. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
