That's a good start but more patches are coming. :-) This branch indeed works somewhat better...

...and the second one is the GK208. That doesn't explain why I did something wrong but heh? :-) You are right. With those bits added locally, the compute support totally hangs the GPU on my GK208 (NV108), and a reboot is needed. Please give a shot at this branch : http://cgit.freedesktop.org/~hakzsam/mesa/log/?h=nvf0_compute It fixes the initialization of the compute state and allows me to launch 'test_input_global' (ie. ./compute 8) on my GK208 without any dmesg fails. That's a good start but more patches are coming. :-) Btw, according to the trace you sent me, you have a GK208b...

...rmi+ because it's already lowered to c0[]. Note that input kernel parameters will be probably sticked on c7[] after my changes but that doesn't change anything for you. I already have a patch for the nv50 bits btw, maybe it's the right time to send it? https://cgit.freedesktop.org/~hakzsam/mesa/commit/?h=compute&id=640d68009bcf93c1814cee0b1a12939cb85e5895 Reviewed-by: Samuel Pitoiset <samuel.pitoiset at gmail.com> On 03/10/2016 04:43 PM, Ilia Mirkin wrote: > On Thu, Mar 10, 2016 at 10:27 AM, Samuel Pitoiset > <samuel.pitoiset at gmail.com> wrote: >> >...

Hi Ilia and Samuel, I rebased my mesa git tree today (it was getting a bit stale) and after that src/gallium/tests/trivial/compute.c stopped working as well as any opencl programs with the kernel in TGSI (as clover on nouveau currently only supports having the kernel in TGSI). The problem is that RES no longer is a valid register-file name in TGSI, specifically this is caused by this commit:
