# pwr-cap-rs

Flake that provides an easy way to limit the power consumption of your Ryzen CPU.

Built using [ryzenadj libraries mappings to rust](https://crates.io/crates/libryzenadj)

Note: for information about supported CPUs check the 

[ryzenadj repo](https://github.com/FlyGoat/RyzenAdj)

## 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:

```nix

  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;

    };

  };

```
