auto-epp-rs
auto-epp-rs is a program 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. This project is a rewrite of the original Python version jothi-prasath/auto-epp in Rust, aiming to improve memory efficiency and overall performance.
Requirements
- AMD CPU with the AMD-Pstate-EPP driver enabled.
- Linux 6.3+
- Rust (make deps)
How to enable amd-pstate-epp
Note: Since Linux 6.5, amd-pstate-epp
is enabled by default, so you can skip this section.
GRUB
This can be done by editing the GRUB_CMDLINE_LINUX_DEFAULT
params in /etc/default/grub
. Follow these steps:
- Open the grub file using the following command:
sudoedit /etc/default/grub
- 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"
systemd-boot
This can be done by editing the options
params in /efi/loader/entries/your-entry.conf
. Follow these steps:
- Open the grub file using the following command:
sudoedit /efi/loader/entries/your-entry.conf
- Within the file, modify the
options
line to include the setting for AMD P-State EPP:
options ... amd_pstate=active
