[Mesa-dev] NIR to TGSI for Vulkan SPIRV shaders
Hi, When running Vulkan code through lavapipe, SPIRV shaders are first converted to NIR. Is it possible to further translate or dump that NIR to TGSI format or is it unsupported? I tried running vkcube with LP_DEBUG=tgsi,tgsi_ir but it segfaulted. Thanks, Tommy ___ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
Re: [Mesa-dev] NIR to TGSI for Vulkan SPIRV shaders
It's not supported and not useful in any way. TGSI llvmpipe is missing a lot of features.
