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 program 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: If you recieve error linker 'cc' not found, then you need to install a C compiler (gcc, cmake, etc.) first.

---

Note: The latest release of acs can also be installed locally with the following

cargo install autoclockspeed

Tested Devices

Auto clock speed has been tested to work on the following devices. If you have a device that is not listed please submit a pull request.

Functionality	Description
Working	All parts of ACS are fully functional, the computer has enough data to make decisions on governor changes and can be run in edit mode
Mostly Working	ACS is unable to understand some data from the computer however certain data (like battery life, battery condition, temperature etc) which is non essential in making governor decisions, is missing
Partially Working	ACS is able to mostly work, although with one or more significant caveat (i.e. jailbreak on Apple devices or root access on Android)
Barely Working	ACS is unable to be run in edit mode due to missing data from the system, monit mode may still work however functionality is limited. If you have a system that falls under this category please open an issue
Borked	ACS cannot find any useful data. Please open an issue

Device Name	Functionality	Notes
Dell XPS 13 9360	Working
Dell Latitude 7480	Working
Steam Deck	Working	Edit mode not neccessary (use built in governor switcher)
Thinkpad T400	Working
Thinkpad T460	Working
Thinkpad X230	Working
Thinkpad X301	Working
Thinkpad W540	Working
ThinkPad X1 Extreme Gen 1	Working
Thinkpad P1 Gen 4 (Intel Core)	Working
Thinkpad P14 Gen 2 (AMD)	Mostly Working	See #443
OnePlus 9 Pro (Snapdragon 888 SoC)	Partially Working	Needs root access; compile from source through termux
iPad Pro Gen 6	Barely Working	Compiles with iSH, but cannot access any data

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)
