...e tests/trivial/compute.c tests to opencl (for the buffer setup and kernel launch, I'm keeping the compute kernels in tgsi as an intermediate step). I've got the test_input_global() test working, see: https://fedorapeople.org/~jwrdegoede/compute-opencl-tgsi.c Next I wanted to convert the test_system_values() test and there I've gotten stuck. It uses a PIPE_BUFFER which it rw-binds as a resource. Which OpenCL does not allow. The closest thing is a constant parameter in OpenCL, at first I've tried binding this as a 2d image, but that leads to the gpu hanging, this is the code activated with &...

That's a good start but more patches are coming. :-) This branch indeed works somewhat better, but things still hang on the test_system_values compute test for me (this is the first test executed I did not try the others). So this seems to need more work. I've ordered a GTX740 (GK107) card, which should arrive soon, and I'll be using that so I can (hopefully) focus on the llvm tgsi bits again. > Btw, according to the trace...

Hi Samual, et al, In http://cgit.freedesktop.org/mesa/mesa/commit/src/gallium/drivers/nouveau?id=ff72440b40211326eda118232fabd53965410afd you write: "This compute support has been tested by Pierre Moreau and myself with some compute kernels." Can you provide testing instructions (and the necessary files) so that I can try to reproduce your tests ? And once I've reproduced your
