There are some improvements on the next one after that though :).

But the real fix for SNB/IVB depends on the DERRMR implementation which we
could not get to work without nasty side effects on Sandy Bridge yet (such
as hangs). Jesse has sent something in this sense for Ivy Bridge in his
'[Intel-gfx] Scanline wait hack for IVB' patch, so hope is not lost yet.

There is a huge thread about this on the
https://bugs.freedesktop.org/show_bug.cgi?id=37686 bug as well.
