pwr-cap-rs

Flake that provides an easy way to tweak the power consumption of your Ryzen CPU. It uses a daemon to look for unintended changes to the power values (e.g., changing power profile) and set them back to those specified in the config file. Built using ryzenadj libraries mappings to rust.

Note: for information about supported CPUs check the ryzenadj repo.

Usage

First, add it to your system flake inputs:

pwr-cap-rs = {
  url = "github:cch000/power-cap-rs";
  inputs.nixpkgs.follows = "nixpkgs";
};

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 = {
    enable = true;
    unplugged = {
      enable = true;
      stapm_limit = 7000;
      fast_limit = 7000;
      slow_limit = 7000;
      apu_slow_limit = 20000;
    };
  };
};
