> Currently, it only supports AMD processors and is being tested on my laptop powered by an AMD Ryzen 7 7840HS that runs Fedora 40. I don't have an Intel machine to learn about `intel_pstate`. If you have an Intel machine and would like to contribute, please do so (see [#4](https://github.com/realKarthikNair/EPP-systemd/issues/4)).
# EPP-systemd
Set Energy Performance Preference based on charging status and battery capacity.
Default behavior if `cpu_performance_config.conf` is not edited:
- If plugged in, sets EPP to `performance` if battery capacity is greater than 50, else sets to `balance_performance`.
- If not plugged in, sets EPP to `balance_performance` if battery capacity is greater than 50, else sets to `power`.
# Dependencies
- Your distro must have systemd.
- The `amd_pstate_epp` scaling driver must be installed/enabled. Running `cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver` will return `amd-pstate-epp` if it is enabled.
# Installation
1. Clone the repository and change into the directory.
```bash
git clone https://github.com/realKarthikNair/EPP-systemd
cd EPP-systemd
```
2. Customize thresholds and EPP by editing `cpu_performance_config.conf` if needed. The file is self explanatory.
3. Run `install-and-enable.sh` after making it executable to install the service and enable it.
```bash
chmod +x install-and-enable.sh
./install-and-enable.sh
```
# Uninstallation
1. Run `uninstall.sh` after making it executable to uninstall the service.
```bash
chmod +x uninstall.sh
./uninstall.sh
```
