(Dave and me are already testing patches for this).
So I haven't commited these yet, because I wanted to see if I could get sb to work. https://cgit.freedesktop.org/~airlied/mesa/log/?h=r600-sb-lds-wip is my non functional attempt, so far, biut it gpu hangs on the nop shader. I'm away for a week, so I might try and look at it against after that.
