# 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](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:
```nix
pwr-cap-rs = {
url = "github:cch000/power-cap-rs";
inputs.nixpkgs.follows = "nixpkgs";
};
```
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 = {
enable = true;
unplugged = {
enable = true;
stapm_limit = 7000;
fast_limit = 7000;
slow_limit = 7000;
apu_slow_limit = 20000;
};
};
};
```
