PowerPlay table editor

A simple GUI tool to inspect and modify AMD GPU powerplay tables. Tries to parse tables the same way as Linux driver does.

Installation

Dependencies:

• Python 3.6 or later
• PyQt 5

On recent Debians/Ubuntus:

$ apt-get install python3-pyqt5 python3-pip git
$ pip3 install --user git+https://github.com/amezin/powerplay-table-editor.git

Usage

GUI app:

$ amdgpu-pptable-editor

View current pptable:

$ amdgpu-pptable-editor /sys/class/drm/card*/device/pp_table

pp_table is only writable by root, so you'll have to save the file to a temporary location and then cp it back to /sys/class/drm/card*/device/pp_table. Or use sudoedit:

$ env EDITOR=amdgpu-pptable-editor sudoedit /sys/class/drm/card*/device/pp_table

Caution!

You can completely screw up your card by modifying its pp_table.
