Don't Expect An Open-Source NVIDIA Vulkan Driver Anytime Soon
Some of the other highlights from Thursday's Nouveau status update include:
- The "ultimate goal" is having OpenGL 4.5 support. They aren't out too far, at least when it comes to Fermi support. The next Mesa release having OpenGL 4.1 done for Maxwell and Pascal.
- They've been working hard on supporting new features of modern NVIDIA GPUs.
- There have been experiments with SPIR-V (the IR of OpenCL 2.1+ and Vulkan) to NV50 IR although extended to support Fermi/Kepler/Maxwell. Basic functionality is supported, including support for if statements, clCreateProgramWithBinary/clCreateProgramWithIL, atomic operations, and more. There is work-in-progress Nouveau SPIR-V support for textures and surfaces. Support for ARB_gl_spirv may be looked at in the future along with mainlining this code.
- While there has been work on SPIR-V support, regarding actual Vulkan support they mentioned "don't expect something soon" and "see you at XDC'17", implying not to expect any Nouveau Vulkan support in the next year.
- The firmware comments and shortcomings as explained in the earlier article.
- At the end, Andy Ritger of NVIDIA does apologize to how the company has been acting with regard to the firmware situation in recent years, etc.
