[PATCH] hwmon: (k10temp) Add per-CCD temperature monitoring for Zen5 Turin
From: Gabriel Ford
Date: Wed Aug 12 2026 - 12:46:15 EST
Add support for per-CCD temperature monitoring on Zen 5 Turin (EPYC 9005)
CPUs, as they fall in a different model range with a larger number of
maximum CCDs compared to their desktop counterparts. Tested and working
on an EPYC 9555P.
