Nouveau FSP support for NVIDIA Hopper and Blackwell GPUs

Code inside the open-source nouveau driver that talks to the Firmware Security Processor on NVIDIA's newest data-center GPUs, including the Hopper H100 and the Blackwell GB10x and GB20x families used in systems like the GB200 NVL72. The FSP is the on-GPU controller that nouveau must negotiate with to boot and run these accelerators.

recommendation

It should stay because this is brand-new code actively being developed to support NVIDIA's current data-center GPUs. Initial Hopper (H100) support landed first, GB10x Blackwell support followed in late 2024, and GB20x enablement continued through 2025, matching products NVIDIA still sells new. There is no alternative upstream driver that handles the Firmware Security Processor handshake nouveau needs to talk to these GPUs.

sources

git.kernel.org
The directory was introduced with GH100 support, indicating it targets modern NVIDIA Hopper GPUs rather than legacy hardware.
git.kernel.org
The code was extended for GB10x support in late 2024, showing active enablement for newer NVIDIA generations.
git.kernel.org
The code was further extended for GB20x support in 2025, reinforcing that this subdriver is still being brought up for current hardware.
nvidia.com
NVIDIA still markets H100 (Hopper) as a current data-center GPU product, so relevant hardware was sold new in 2025 and remains broadly available.
nvidia.com
NVIDIA markets GB200/Blackwell systems as current products, matching the GB10x/GB20x enablement work in this directory and indicating ongoing new deployments.

codex reasoning notes (technical)

Not an early-exit case: this is a hardware-facing nouveau nvkm subdevice for the GPU Firmware Security Processor. lore-specific tooling was unavailable here (no working lore-http MCP and `lei` missing), so upstream activity was inferred from local `git log` on the directory, then mapped to canonical git.kernel.org commit URLs by canonical recall. Web search provided the NVIDIA product-page URLs. The directory is very new, gained GH100 then GB10x/GB20x support in 2024-2025, and only shows later treewide cleanups in 2026; that pattern fits active bring-up, not obsolescence. No natural upstream replacement driver exists for nouveau's FSP path.
