Ryzen SVI2 monitoring Linux driver

Software & Operating Systems Linux

Hello everyone,

I want to share with you a simple driver for monitoring SVI2 voltage, current and power for AMD Ryzen cpus. I have created it because I couldn’t find any other way how to monitor these values on Linux. So far I have tested it only on my Ryzen 3 box.

If anyone’s interested, the source code and instructions are hosted on github: https://github.com/ocerman/zenpower

BTW: This is my first linux module, if anyone have ideas for improvrements, PRs are welcome.

I’m going to give this a look. I’m curious if we shouldn’t consider merging this into the k10temp module? Would be nice to have it in mainline.

Tried this out on my ryzen 5 1600, seems to be working quite well. It’s nice to not have to use Windoze to monitor SVI2 now. The it87 sensors on my mobo are not very accurate or reliable.

This is looking quite good, i might be taking a try at simplifying this and patching it into k10-temp.
