auto-epp

auto-epp

auto-epp is a python script that manages the energy performance preferences (EPP) of your AMD CPU using the AMD-Pstate driver. It adjusts the EPP settings based on whether your system is running on AC power or battery power, helping optimize power consumption and performance.

Index

Requirements

  • AMD CPU with the AMD-Pstate-EPP driver enabled.
  • Python 3.x

To enable amd-pstate-epp

This can be done by editing the GRUB_CMDLINE_LINUX_DEFAULT params in /etc/default/grub. Follow these steps:

  1. Open the grub file using the following command:
sudo nano /etc/default/grub
  1. Within the file, modify the GRUB_CMDLINE_LINUX_DEFAULT line to include the setting for AMD P-State EPP:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amd_pstate=active"
