Nouveau memory controller and framebuffer support for NVIDIA GPUs

The part of the open-source Nouveau driver that talks to the memory controller and framebuffer hardware on NVIDIA GPUs from the GeForce 8 series (NV50, circa 2006) all the way through current Hopper and Blackwell chips, including the GeForce RTX 50-series cards still being sold new in 2025.

recommendation

It should stay because this code is actively maintained and is gaining support for NVIDIA's newest GPUs, not winding down. Patches added GH100 (Hopper) and GB20x (Blackwell, RTX 50-series) support during 2024 and 2025, and a bug fix for the framebuffer flush-page logic landed as recently as November 2025, so it directly serves hardware on store shelves today.

codex reasoning notes (technical)

Not a removal candidate. Local git history via exec_command shows active substantive work through 2025-11-13 in this exact path, plus 2024-2025 enablement for GH100/GB10x/GB20x and no real remove/deprecate discussion hits for the path. spinics.net patch URLs were obtained by web search on exact nouveau patch subjects; the patch.msgid.link URL was obtained from local git commit metadata via exec_command; the NVIDIA RTX 5090 URL was obtained by web search. Because this subtree supports current Blackwell hardware and still receives fixes, the correct hint is keep.
