NVIDIA Makes More Hopper & Blackwell Header Files Open-Source

Written by Michael Larabel in NVIDIA on 21 July 2025 at 11:54 AM EDT. 22 Comments
Last week NVIDIA open-sourced 12k lines of C header files for Blackwell GPUs to help in the open-source driver efforts, namely for Nouveau / NVK and the in-development NOVA Rust driver. On Friday they made public some additional header files for helping in the Blackwell and Hopper open-source driver enablement.

Following the previously-covered open-source header activity, on Friday this commit was pushed to their open-source documentation repository that provides Hopper and Blackwell DMA-copy class header files.

This is another one thousand lines of MIT-licensed header files for helping with the open-source NVIDIA Linux driver efforts.

In turn the code has already been imported into Mesa Git.
