I would like to announce a new project for tweaking AMDGPUs on Linux. It's an open-source solution for people that would like to write their own scripts. It uses node.js and has a library part and script part.
https://github.com/kobalicek/amdtweakIt's unfinished project and I just released it as a preview. I would like to get some feedback before I start adding more features. I designed it as a library, but I would like to provide more scripts and problem solutions in the future.
