Altough the compute support is still not complete because textures and
surfaces need to be implemented, it allows to launch very simple compute
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...)
Hmm, my only compute capable card actually is a nvf0 card (gk208 based). Can you
provide some quick test instructions how I can test compute on that card
(with the patch from this thread applied) ?
And if it does not work, any suggestions how to go about debugging this ?
Or better any info I can provide to help you debug this :)
Regards,
Hans
