From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
It's been a while since I last ran igt on gen2, so I figured I'd
give it a shot. 855 had some failures, 830 no longer worked at
all. So I went ahead and fixed them, and here's the result.
The first three patches are not even gen2 specific bugs I caught
with this effort. The rest is for gen2.
I have some fixes for igt as well, which I'll post separately.
The good news is that with these patches (and the igt fixes) my
855 completes a full kms_flip run without failures, and the BAT
set has only one failure (gem_render_tiled_blits). 830 is fairly
good too, but it does have a lot of underruns and pipe_assert()
dmesg warnings. Lot of those are due to the pipe enable quirks
since we implement those quite haphazardly.
The series is available here:
