The k10temp driver in Linux 7.3 now exposes individual core complex die (CCD) temperatures for AMD EPYC 9005 series processors.
Per-CCD temperature monitoring allows finer-grained thermal management and fault detection in AMD EPYC Zen 5 servers. Operators can now identify hotspots at the CCD level rather than relying on a single socket-wide reading, improving reliability and performance tuning.
