Usage

First add it to your system flake inputs:

pwr-cap-rs.url = "github:cch000/pwr-cap-rs;

Then you can use it by adding somewhere in your config:

  imports = [
    inputs.pwr-cap-rs.nixosModules.pwr-cap-rs
  ];

  #example config
  services.pwr-cap-rs = {
    enable = true;
    tctl_limit = 85;
    quiet = {
      unplugged = {
        enable = true;
        stapm_limit = 7000;
        fast_limit = 7000; #cannot be null if the profile is enabled
        #slow_limit = 7000;
        apu_slow_limit = 20000;
      };
      plugged.enable = false;
    };
    balanced = {
      unplugged.enable = false;
      plugged.enable = false;
    };
    performance = {
      unplugged.enable = false;
      plugged.enable = false;
    };
  };
