auto-clock-speed

See on GitHub

ACS Upstream - autoclockspeed.org - Our crates.io - ACS GitHub Org

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.

Want to help? Yay! Welcome!

• Read our CONTRIBUTING.md for some helpful tips
• Find an issue - “good first issue” recommended
• Feel free to ask questions!

Install Latest Release

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

1. Go to rustup.rs to install rust.

2. Setup rust

   rustup override set stable
   rustup update stable
   

3. Clone the project and install

   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

cargo install autoclockspeed

In Action

New Interactive Mode

Systemd

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

# 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)

# 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/

# 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 --quiet

[Install]
WantedBy=multi-user.target

Config

Using default config

WARN: Using default config. Create file '/etc/acs/acs.toml' for custom config or run 'acs initconfig' to setup default config automatically.

This warning recommends creating a config file, use the initconfig command to automatically create one for you!

sudo acs initconfig

This is an example config

also the default settings if no config is provided

# acs.toml
powersave_under = 20
overheat_threshold = 80
active_rules = [ "battery_percent_rule", "lid_open_rule", "ac_charging_rule", "cpu_usage_rule" ]

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.

# 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.

# 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 examples of how acs can be used.

# 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)
