PowerStation is an open source TDP control and performance daemon for Linux that can be used to control CPU and GPU settings for better performance and battery life. Performance control is done through DBus to provide a UI-agnostic interface to CPU and GPU settings.
You can install with:
make build
sudo make installIf you are using ArchLinux, you can install PowerStation from the AUR:
yay -S powerstation-binThen start the service with:
sudo systemctl enable powerstation
sudo systemctl start powerstationXML specifications for all interfaces can be found in bindings/dbus-xml.
Individual interface documentation can be found here:
- org.shadowblip.CPU
- org.shadowblip.CPU.Core
- org.shadowblip.GPU
- org.shadowblip.GPU.Card
- org.shadowblip.GPU.Card.Connector
When PowerStation is running as a service, you can interact with it over DBus. There are various DBus libraries available for popular programming languages like Python, Rust, C++, etc.
You can also interface with DBus using the busctl command:
