NixOS profiles to optimize settings for different hardware.

Add and update nixos-hardware channel:

$ sudo nix-channel --add https://github.com/NixOS/nixos-hardware/archive/master.tar.gz nixos-hardware
$ sudo nix-channel --update

Then import an appropriate profile path from the table below. For example, to enable ThinkPad X220 profile, your imports in /etc/nixos/configuration.nix should look like:

imports = [
  <nixos-hardware/lenovo/thinkpad/x220>
  ./hardware-configuration.nix
];

New updates to the expressions here will be fetched when you update the channel.

There is also experimental flake support. In your /etc/nixos/flake.nix add the following:

{
  description = "NixOS configuration with flakes";
  inputs.nixos-hardware.url = github:NixOS/nixos-hardware/master;

  outputs = { self, nixpkgs, nixos-hardware }: {
    # replace <your-hostname> with your actual hostname
    nixosConfigurations.<your-hostname> = nixpkgs.lib.nixosSystem {
      # ...
      modules = [
        # ...
        # add your model from this list: https://github.com/NixOS/nixos-hardware/blob/master/flake.nix
        nixos-hardware.nixosModules.dell-xps-13-9380
      ];
    };
  };
}

You can fetch the git repository directly:

imports = [
  "${builtins.fetchGit { url = "https://github.com/NixOS/nixos-hardware.git"; }}/lenovo/thinkpad/x220"
];

Unlike the channel, this will update the git repository on a rebuild. However, you can easily pin to a particular revision if you desire more stability.

See code for all available configurations.

1. Add your device profile expression in the appropriate directory
2. Link it in the table in README.md and in flake.nix
3. Run ./tests/run.py to test it. The test script script will parse all the profiles from the README.md
