A simple systemd service unit to tune the performance of AMD GPU, and optionally apply automatically on boot.
This software only supports recent AMD GPUs using the amdgpu kernel driver. It is tested on RDNA2/RX 6000 series — tested on the Asus ROG Strix G15 (2021) laptop, RX 6800M.
You must append the boot parameter amdgpu.ppfeaturemask=0xffffffff to the kernel command in the bootloader. How to do that varies per Linux distribution. Check your OS' documentation.
Edit the environment variables in the [email protected] file to tune the settings. Then you can install the service to the /etc/systemd/system folder:
sudo ./make installStarting the service [email protected] applies the configuration. Starting the service [email protected] resets the configuration back to defaults.
# Apply configuration
sudo systemctl start [email protected]
# Reset configuration
sudo systemctl start [email protected]You can keep tuning the configuration by just editing the file at /etc/systemd/system/[email protected]. After making changes, you have to reload and restart the service to apply the new settings:
sudo systemctl daemon-reload && sudo systemctl restart [email protected]After you have tuned the settings to your liking — and found a stable configuration! — you can optionally enable the systemd timer unit to have your settings always applied automatically on boot:
sudo systemctl enable [email protected]sudo ./make uninstall
# Or, without a clone of this repository, you can use these commands instead
sudo systemctl disable --now [email protected]
sudo rm -f /etc/systemd/system/amdgpu-tune@{.service,apply.timer}This is free and unencumbered software released into the public domain.
