Intel Low Power Mode Daemon as a NixOS module

This flake provides a Nix wrapper for the intel-lpmd daemon.

Installation as NixOS module

1. Add to flake.nix:

inputs = {
  nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";

  intel-lpmd-flake.url = "github:dmfrpro/intel-lpmd-flake";
  intel-lpmd-flake.inputs.nixpkgs.follows = "nixpkgs";
};

2. Add to your module imports:

outputs = { self, nixpkgs, intel-lpmd-flake, ... }: {
  nixosConfigurations.host = nixpkgs.lib.nixosSystem {
    system = "x86_64-linux";
    modules = [
      intel-lpmd-flake.nixosModules.default
    ];
  };
};

3. Enable the service:

{
  services.intel-lpmd = {
    enable = true;
    config.meteorLake = true;  # meteorLake / lunarLake / pantherLake / experimental / custom
    mode = "ON";  # ON / OFF / AUTO
    debug = true;
  };
}

All options
