mlnx-ofed-nixos

A small subset of Mellanox OFED packages ported to NixOS.

Warning

This project is experimental and may stay experimental for a long time. Not all packages are fully tested, because I don't have the hardware to validate some of the scenarios like InfiniBand. Any help or suggestions are welcomed.

Quick start

With flakes

This flake provides:

• overlays.default for adding packages into your pkgs
• nixosModules.default for easy configuration

A simple example flake would be:

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
    mlnx-ofed-nixos = {
      url = "github:NixOS/nixpkgs/nixos-unstable";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

  outputs = { self, nixpkgs, ... }@inputs: {
    nixosConfigurations.default = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [
        # Add packages from this repo and set up binary cache
        inputs.mlnx-ofed-nixos.nixosModules.setupCacheAndOverlays
        # Add configuration options from this repo
        inputs.mlnx-ofed-nixos.nixosModules.default
        # Example configuration
        ({ config, ... }: {
          hardware.mlnx-ofed = {
            enable = true;
            fwctl.enable = true;    
            nvme.enable = true;
            nfsrdma.enable = true;
            kernel-mft.enable = true;
          };
        })
      ];
    };
  };
}
