    Phoronix: The OpenCL 2.0 CTS Can Now Run On Gallium3D Clover - But Doesn't Pass The Tests

    Red Hat's Karol Herbst who has spent years now working on Nouveau SPIR-V support and other GPU open-source compute efforts around Mesa has provided a trivial implementation of clCreateCommandQueueWithProperties() that is now enough to begin running the OpenCL 2.0 conformance test suite on the Gallium3D "Clover" state tracker...

    Does this statetracker still work for radeonsi?

      It is really incomplete.

        Yes.

        Device Name AMD Radeon (TM) RX 470 Graphics (POLARIS10, DRM 3.35.0, 5.4.15-zen1-1-zen, LLVM 11.0.0)
        Device Vendor AMD
        Device Vendor ID 0x1002
        Device Version OpenCL 1.1 Mesa 20.1.0-devel (git-35961b10da)
        Driver Version 20.1.0-devel

        but

        Device OpenCL C Version OpenCL C 1.1

        but when it works is faster than amdgpu-pro opencl implementation or at least on luxrender benchmarks

          Note: The biggest reason that it's reporting CL 1.1 instead of 1.2 is probably that the libclc project doesn't support the 'printf()' function for debugging kernel execution, yet. You can override the CL/CLC versions exposed via environment variables in clover, which also enables several CL 1.2 features (e.g. volatile, extern, static keywords). Maybe there's other things, but I've always avoided pushing to report 1.2 capabilities in clover because we might as well finish up 1.1 (and get a passing CTS run on at least one GPU) before we start telling people we support an incomplete 1.2 implementation...

            But compilation of

            current LLVM git (e.g. 10.0-rcX) with SPIRV-LLVM-Translator (included)

            and then

            Mesa Clover with '-Dopencl-spirv=true'

            is still broken.

            See mesa-devel and my posts to Karol.

              Can second that. For all _3_ luxrender 'versions'.
