auto-cpufreq

Automatic CPU speed and power optimizer

TLDR

Monitor CPU frequency and power

$ sudo auto-cpufreq --monitor

Run in live mode (temporary optimization)

$ sudo auto-cpufreq --live

Show statistics

$ sudo auto-cpufreq --stats

Install as system service

$ sudo auto-cpufreq --install

Remove system service

$ sudo auto-cpufreq --remove

Force specific governor

$ sudo auto-cpufreq --force=powersave

Update auto-cpufreq

$ sudo auto-cpufreq --update

auto-cpufreq is an automatic CPU speed and power optimizer for Linux. It dynamically adjusts CPU frequency scaling and turbo boost based on system load and power source (AC/battery) to optimize performance and battery life.

PARAMETERS

--monitor

Monitor CPU frequency, governor, and power information

--live

Run in live mode with temporary optimization

--stats

Display statistics from daemon mode

--install

Install auto-cpufreq as a system service

--remove

Remove auto-cpufreq system service

--update

Update auto-cpufreq to latest version

--force=GOVERNOR

Force a specific governor (powersave, performance)

--config PATH

Use custom configuration file

--debug

Enable debug output

CONFIGURATION

/etc/auto-cpufreq.conf

Main configuration file. Defines governor and turbo boost preferences per power source (charger/battery).

CAVEATS

Using --install creates a systemd service for automatic operation. The --live and --monitor modes are for testing and do not persist after reboot. For laptops, auto-cpufreq automatically switches between performance and powersave based on power source.

HISTORY

auto-cpufreq was created to provide automatic CPU frequency optimization without manual tuning, particularly useful for laptops to extend battery life while maintaining performance when needed.
