At least I've never tried to understand this particular loop. The VGA_MODE_DISABLE thing I did manage to figure out. Whether that might have been a contributing factor for adding this loop is unclear. We actually have a couple more DPLL writes just before the loop, so we might want consider folding those into the loop as well. > > Reviewed-by: Chris Wilson <chris@xxxxxxxxxxxxxxxxxx> > -Chris > > -- > Chris Wilson, Intel Open Source Technology Centre -- Ville Syrjälä Intel OTC _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
