# auto-cpufreq
|
|
|
|
Automatic CPU speed & power optimizer for Linux based on active monitoring of laptop's battery state, CPU usage and system load. Ultimately allowing you to improve battery life without making any compromises.
|
|
|
|
For tl;dr folks there's a: [Youtube: auto-cpufreq - tool demo](https://www.youtube.com/watch?v=QkYRpVEEIlg)

## Why do I need auto-cpufreq?
|
|
|
|
One of the problems with Linux today on laptops is that CPU will run in unoptimized manner which will negatively reflect on battery life. For example, CPU will run using "performance" governor with turbo boost enabled regardless if it's plugged in to power or not.
|
|
|
|
Issue can be mitigated by using tools like [indicator-cpufreq](https://itsfoss.com/cpufreq-ubuntu/) or [cpufreq](https://github.com/konkor/cpufreq), but these still require maual action from your side which can be daunting and cumbersome.
|
|
|
|
Using tools like [TLP](https://github.com/linrunner/TLP) will help in this situation with extending battery life (which is something I did for numerous years now), but it also might come with its own set of problems, like losing turbo boost.
|
|
|
|
With that said, I needed a simple tool which would automatically make "cpufreq" related changes, save battery like TLP, but let Linux kernel do most of the heavy lifting. That's how auto-cpufreq was born.
|
|
|
|
Please note: this tool doesn't conflict and [works great in tandem with TLP](https://www.reddit.com/r/linux/comments/ejxx9f/github_autocpufreq_automatic_cpu_speed_power/fd4y36k/).

## Installing auto-cpufreq
|
|
|
|
### Snap store
|
|
|
|
auto-cpufreq is available on [snap store](https://snapcraft.io/auto-cpufreq), or can be installed using CLI:
|
|
|
|
```
|
|
sudo snap install auto-cpufreq
|
|
```
|
|
|
|
**Please note:** once [snapd](https://snapcraft.io/docs/installing-snapd) is installed, your `snap version` version must be >= 2.44 for `auto-cpufreq` to fully work due to [recent snapd changes](https://github.com/snapcore/snapd/pull/8127). Currently, this version is only available on Ubuntu 20.04.
|
|
|
|
### auto-cpufreq-installer
|
|
|
|
Get source code, run installer and follow on screen instructions:
|
|
|
|
```
|
|
git clone https://github.com/AdnanHodzic/auto-cpufreq.git
|
|
cd auto-cpufreq && sudo ./auto-cpufreq-installer
|
|
```
|
|
|
|
In case you encounter any problems with `auto-cpufreq-installer`, please [submit a bug report](https://github.com/AdnanHodzic/auto-cpufreq/issues/new).
|
|
|
|
### Arch Linux
|
|
|
|
[AUR package is available](https://aur.archlinux.org/packages/auto-cpufreq-git/) for install. After which `auto-cpufreq` will be available as a binary and you can skip to [auto-cpufreq: modes and options](https://github.com/AdnanHodzic/auto-cpufreq#auto-cpufreq-modes-and-options) for further reference.
|
|
|
|
## How to run auto-cpufreq
|
|
|
|
auto-cpufreq can be run by simply running the `auto-cpufreq` and following on screen instructions, i.e:
|
|
|
|
`sudo auto-cpufreq`
|
|
|
|
#### Running auto-cpufreq on AMD CPU and/or desktop/servers's
|
|
|
|
Please note when this tool was made it was solely targeting Intel CPU's running on laptops. Support for both AMD CPU is [currently being worked on](https://github.com/AdnanHodzic/auto-cpufreq/issues/17).
|
|
|
|
While there are plans to [extend support for desktop/servers](https://www.reddit.com/r/linux/comments/ejxx9f/github_autocpufreq_automatic_cpu_speed_power/fd5nodm/) in near future.
|
|
|
|
## auto-cpufreq modes and options
|
|
|
|
### Monitor
|
|
|
|
`sudo auto-cpufreq --monitor`
|
|
|
|
No changes are made to the system, and is solely made for demonstration purposes what auto-cpufreq could do differently for your system.
|
|
|
|
### Live
|
|
|
|
`sudo auto-cpufreq --live`
|
|
|
|
Necessary changes are temporarily made to the system which are lost with system reboot. This mode is made to evaluate what the system would behave with auto-cpufreq permanently running on the system.
|
|
|
|
### Install - auto-cpufreq daemon
|
|
|
|
Necessary changes are made to the system for auto-cpufreq CPU optimizaton to persist across reboots. Daemon is deployed and then started as a systemd service. Changes are made automatically and live log is made for monitoring purposes.
|
|
|
|
`sudo auto-cpufreq --install`
|
|
|
|
After daemon is installed, `auto-cpufreq` is available as a binary and is running in the background. Its logs can be viewed by running: `auto-cpufreq --log`
|
|
|
|
Since daemon is running as a systemd service, its status can be seen by running:
|
|
|
|
`systemctl status auto-cpufreq`
|
|
|
|
### Remove - auto-cpufreq daemon
|
|
|
|
auto-cpufreq daemon and its systemd service, along with all its persistent changes can be removed by running:
|
|
|
|
`sudo auto-cpufreq --remove`
|
|
|
|
### Log
|
|
|
|
If daemon has been instaled, live log of CPU/system load monitoring and optimizaiton can be seen by running:
|
|
|
|
`auto-cpufreq --log`
|
|
