[Tracking issue] CDI Support

[SomeoneSerge]

Background

• NixOS: Add support for CDI #284507 introduces CDI support in the form of virtualisation.containers.cdi.{dynamic,static} options;
• CDI: Add mount-nvidia-binaries and mount-nvidia-docker-1-directories options #290979 removes in favour a more modest and specific hardware.nvidia-container-toolkit; the alternative, designing a consistent generic interface, might be too time consuming;

Tasks left

<...>

exportReferencesGraph

• Nvidia: unbreak: we're currently mounting incomplete closures; need to use exportReferencesGraph¹²

EGL

• Nvidia: unbreak EGL, nixos/virtualisation.containers.cdi.dynamic.nvidia: EGL broken #297537.

misc

• Remove the generic interface and introduce an nvidia-specific interface (WIP in CDI: Add mount-nvidia-binaries and mount-nvidia-docker-1-directories options #290979).

• Nvidia: Introduce options to mount FHS bin/lib paths in containers.

• Nvidia: Only seems to work with podman, not with docker_25, containers.cdi.dynamic.nvidia with docker_25 does not enable gpu use in containers #305312

• ...

  • Verify that Nixpkgs programs that expect addDriverRunpath.driverLink (/run/opengl-driver/lib) work out of the box

Since #306337 merged, we can mark the 'Nvidia: Only seems to work with podman, not with docker_25' checkbox too :)
