Altough the compute support is still not complete because textures and

kernel like one which reads reading MP performance counters.
Didn't those end up breaking 3d rendering? Have you figured out what
was overwriting what?
This doesn't break any stuff related to 3D rendering. The compute kernel
for reading perf counters has been tested a lot on different chips.
The compute support is already enabled on Kepler and it doesn't seem to
break 3D rendering, btw.
In the series which fixed those perf counters, I actually introduced a
bug which has been fixed since: fc5ae0c13f71f049065b1422c20491d2264ae164
This turns on PIPE_CAP_COMPUTE and PIPE_SHADER_COMPUTE.

Of course this also enables it for NVF0_3D_CLASS. Pretty sure compute
doesn't work there for some dumb reason (like we're missing some in
our ctxsw fw...)
