Plans are to get SPIR-V support for Nouveau with a cheap way. Before that I was looking into Pierres work on his direct SPIR-V to nvir pass and seemed much more complicated than doing NIR to nvir.
In the end we still plan to get Compute support through SPIR-V and my hope is to get that piped through NIR, so that a lot of other drivers could benefit from this as well. Stuff up to GLSL 1.30 should work (just 2 piglit fails up to that), some games run as well (truth is, I only checked one, but I expect that more will run). Usually I took the add-stuff-until-piglit-test-passes approach so a lot of details are still missing. But nevertheless I would like to get some feedback on the work and suggestions for improving this work. To use NIR just set NV50_PROG_USE_NIR=1 for a mesa DEBUG build. I plan to move it to a non debug variable for the next series. Features I want to work next on: * Geometry shaders * UBOs ./piglit run -x glx -x egl -x streaming-texture-leak -x max-texture-size tests/gpu.py: [26073/26073] skip: 1574, pass: 13451, warn: 9, fail: 5287, crash: 5752 Note: a lot of crashes are geometry/tesselation stuff hitting asserts.
