Auto Clock Speed (acs)

A utility to check stats about your CPU, and auto regulate clock speeds to help with either performance or battery life. This proram is designed for Linux and Intel laptops, although it should theoretically work on AMD systems and sometimes desktops as well. If you encounter any issues or bugs, please refer to the wiki to see if there is a solution

Goals

First and foremost, this is a project to learn about Rust and Linux
Secondly, try to improve upon AdnanHodzic's already amazing auto-cpufreq
Add options to display raw output of governors, clockspeed, turbo, battery, etc. for use in scripts or display panels like polybar.

Install Latest Release

If you have cargo on your machine, skip to step 3

Go to rustup.rs to install rust.
Setup rust sh rustup override set stable rustup update stable
Clone the project and install ```sh git clone https://github.com/JakeRoggenbuck/auto-clock-speed

cargo install --path auto-clock-speed

This is needed to have the root version of acs match the local installed version

sudo cp ~/.cargo/bin/acs /usr/bin/acs ```

Note: The latest release of acs can also be installed locally with the following sh cargo install autoclockspeed

In Action

Systemd

In order to have auto-clock-speed start when you restart your computer you must follow these instructions ```sh

IMPORTANT: Modify the service file (acs.service) in the

project directory to include the path to the binary file

(usually /home/username/.cargo/bin/acs)

```

```sh

In the auto clock speed directory run this command to

move the service file into your systemd directory

sudo cp acs.service /etc/systemd/system/ ```

```sh

Start and enable the service

sudo systemctl start acs sudo systemctl enable acs

Check service is up and running

systemctl status acs ```

Systemctl command

The line after [Service] in acs.service is the command that will be run. You may want to add or remove arguments, mainly --quiet. ``` [Unit] Description=Manages Clock Speed

[Service] ExecStart=/home/your-user-here/.cargo/bin/acs run --no-animation

[Install] WantedBy=multi-user.target ```

Config

Using default config

sh WARN: Using default config. Create file /etc/acs/acs.toml for custom config. This warning recommends creating a config file, use the following example and install at /etc/acs/acs.toml

sh mkdir /etc/acs cp ./acs.toml /etc/acs/acs.toml

This is an example config

also the default settings if no config is provided

```yaml

acs.toml

powersaveunder = 20 overheatthreshold = 80 ```

Turn Off

If you would like to turn off auto-clock-speed, here are the steps.
Note: This should be done during testing of acs run mode. ```sh

Temporarily stop (only lasts until reboot)

sudo systemctl stop acs

Permanently stop until turned on

sudo systemctl disable acs ```

Uninstall

Here is how to uninstall the binary and the systemctl service. ```sh

Remove local binary

cargo uninstall acs

Remove system shared binary

rm /usr/bin/acs

Remove systemctl entry

rm /etc/systemd/system/acs.service ```

Example Usage

Here are some examles of how acs can be used. ```sh

Monitor mode

acs monitor

Run as root

sudo acs run

Get all speeds

acs get speeds

Select gov from dmenu

sudo acs set gov $(acs get available-govs --raw | dmenu) ```
