David Airlie's experimental patches have enabled the Nouveau+NVK open-source driver stack to run on NVIDIA's DGX Spark GB10. Engineers can now explore the potential of this setup, though it primarily serves as a precursor to the Nova driver transition.
In a notable development for the open-source graphics community, Red Hat's David Airlie has successfully implemented experimental patches that allow the Nouveau reverse-engineered kernel graphics driver and Mesa NVK Vulkan driver to operate on the NVIDIA DGX Spark GB10 system. This achievement is significant for those working with the Grace Blackwell Superchip, as it opens up new opportunities for testing and development on this powerful hardware.
The technical journey to this point involved adapting the Nouveau driver to work with NVIDIA's newer R610 firmware. This was no small task, given NVIDIA's lack of backward compatibility for their firmware images across different driver releases. The Nouveau driver required substantial reworking, including patches for display code, vRAM, and L2 cache handling fixes, along with specific support for the DGX Spark's boot and display configurations. On the NVK Vulkan driver side, Airlie addressed depth/stencil and vRAM differences with targeted patches.
In total, around 100 patches were necessary to bring this functionality to life, marking a significant, albeit invasive, effort. These developments, while promising, are seen as a stepping stone towards the anticipated transition to the Nova driver. Airlie himself hinted at this future direction in his blog post, suggesting that the current work might be more of a temporary measure.
For engineers eager to explore this setup, Airlie has shared a screenshot of the Nouveau+NVK running on the NVIDIA GB10, showcasing the potential of this driver stack. While the practical applications may be limited for now, this work lays the groundwork for broader support and functionality in the future.
