Phoronix: Nouveau Finally Lands SPIR-V Support As Part Of OpenCL Push

Going back to December 2017 we've been tracking the Red Hat led effort on improving Nouveau's OpenCL compute support that involves adding NIR/SPIR-V support and improvements to the Clover Gallium3D state tracker. To much surprise, this morning the SPIR-V support for this open-source NVIDIA driver was merged for Mesa 19.3...

Would be nice if Clover worked cross-vendor with popular OCL software (Blender Cycles, folding@home...).

that's kind of the goal. It will just take a while, but now it's much easier for nir based driver to make user of clover, as without those patches having an LLVM backend was required.

does this mean nouveau gets opengl 4.6 support?

Lets hope that Iris and the AMD Gallium drivers that move over to Nir make use of this too - maybe finally having an OpenCL solution that just works will encourage AMD to get their finger out

Wonder if this means hashcat can run on Nouveau

Enabling spirv support wouldn't be the smartest move right now as the NIR path isn't that well tested. And until games/applications actually require it, there is no real benefit enabling the extension. We could write up all the code though in case somebody force enables the spirv extensions.

did you hear about plans of switching to clover from someone at intel or amd?
