From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
Since the 830M dragon popped up again, I figured I'd dig out my old patches
that try to fix it.
I ended up reworking the primary plane code a bit also to eliminate the
DSPCNTR/DSPADDR RMW accesses since those are dangerous on 830M. But I think
the end result is more in line where we want to go anyway with the primary
planes anyway.
This has been tested on my Lifebook S6010 and this is the first time two
displays work reliably on this thing. Additionally we still need the minimum
watermark fix, for now I just used a hack (didn't include it here).
The only thing that doesn't work is suspend to ram. It suspends but won't
wake up, but that happens w/o i915 also so I can't take the blame for that.
I pushed the lot to [1] and the watermark hack is included there as well.
