A simple daemon for setting cpu frequency governor

Inspired by auto-cpufreq, afreq.sh is a minimal daemon built on posix shell and core utils, it is intended to be extensible, lean and have the least amount of dependencies possible.

As of now afreq depends only on:

• core utils (grep, sleep, tail, awk, head, realpath, cat) however a sleep command that supports float values is needed
• built ins (printf, command)
• posix shell interpreter (dash, bash, busybox ash)
• procps (vmstat, pgrep)

installation

Install everything:

sudo make install-all

this will provide:

install config

Edit the config.mk file to tweak installation options.

SysV init script

This repo provides 2 sysvinit init scripts, a hand written one and one that uses Debian's init-d-script framework that provides a Debian and LSB compliant init.d script that may be preferred on some environments, you can choose with the config.mk file.

Usage

sysvinit

The makefile should put the script in /etc/init.d/acpufreq by default, after that a simple sudo update-rc.d acpufreq defaults should be enough to activate it for the next boot

The service script supports the standard actions.

A simple sudo service acpufreq start will initiate the daemon.

systemd

The makefile should put the unit in /etc/systemd/system/acpufreq.service by default, all you need is run sudo systemctl enable acpufreq to activate the service for the next boot.

Initiate the service with sudo systemctl start acpufreq

configuration

Altho the default settings used internally by the daemon ought to work for most setups you can do tweak them to your liking or usecase, the installation provides an example config file and the manpage contains information about the available settings and their possible values.
