smutool

This tool aids in the reverse engineering of AMD SMU. The SMU is a LatticeMico32 co-processor residing in the mainboard for controlling thermal management, clocks, and fans etc.

The purpose of this project is to collaborate with others to create a free alternative firmware SMU stack that interoperates with coreboot.
