Hi, I've already said in my patch submission (which was Cc'ed to LKML, linux-edac and linux-hwmon so you should have been able to find it): >> It appears SMU offsets for reading current/voltage and CCD temperature >> have changed for this generation (reads from currently used offsets >> yield zeros), so those features cannot be enabled so trivially. In https://github.com/FlyGoat/ryzen_nb_smu/issues/3 there some reverse-engineered info that indicates that for Renoir, SMU region has been moved to 0x6F000. Its layout also changed, as far as I can tell. (also, please ask yourself if you want to offer the maintainers an apology) Alexander
