SimpleDeckyTDP

This is a very simple Linux TDP Decky Plugin that wraps ryzenadj

Compatibility

Tested on ChimeraOS Stable (44-1 and 43-1), ChimeraOS 45 unstable, and Bazzite Deck Edition.

Other distros not tested.

Bazzite may require you to configure iomem=relaxed as an additional kernel parameter.

Requirements

WARNING: This plugin assumes you already have ryzenadj installed and can be located in your PATH

To check this, you can run which ryzenadj in a terminal/console, which should print out a path to a ryzenadj binary.

e.g.

$ which ryzenadj
/usr/bin/ryzenadj

If you do not have ryzenadj installed, you will need to get a working copy installed onto your machine.

To test your ryzenadj to make sure that it's functional, run the following:

$ sudo ryzenadj -i

This should print out a table that looks something like the following:

CPU Family: Rembrandt
SMU BIOS Interface Version: 18
Version: v0.13.0 
PM Table Version: 450005
|        Name         |   Value   |     Parameter      |
|---------------------|-----------|--------------------|
| STAPM LIMIT         |     8.000 | stapm-limit        |
| STAPM VALUE         |     0.062 |                    |

If you see an error, you may need to set iomem=relaxed as a boot parameter for your kernel.
