From b38f98990dc4407c82bad532fa14f6460e83492a Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Thu, 26 Apr 2018 12:22:29 -0700 Subject: [PATCH] hwmon: (k10temp) Display both Tctl and Tdie With temperature offsets applied to some but not all CPU types, display both Tdie and Tctl for those CPUs where the temperatures may be different.
