As a consequence lots of RevG systems report temperatures like: $ sensors k8temp-pci-00c3 Adapter: PCI adapter Core0 Temp: +17 C Core0 Temp: +3 C Core1 Temp: +21 C Core1 Temp: +5 C being quite below ambient temperature. There are even reports of negative temperature values. This patch corrects the temperature reporting of k8temp for RevG desktop CPUs.

Current Temperature for K8 RevG desktop CPUs is a "normalized value"
which can be below ambient temperature.

As a consequence lots of RevG systems report temperatures like:

$ sensors
k8temp-pci-00c3
Adapter: PCI adapter
Core0 Temp:    +17 C
Core0 Temp:     +3 C
Core1 Temp:    +21 C
Core1 Temp:     +5 C

being quite below ambient temperature.
There are even reports of negative temperature values.

This patch corrects the temperature reporting of k8temp for
RevG desktop CPUs.

hwmon: (k8temp) Fix wrong sensor selection for AMD K8 RevF/RevG CPUs 2009-01-15T21:27:47+00:00 Andreas Herrmann andreas.herrmann3@amd.com 2009-01-15T21:27:47+00:00 a2e066bba2aad6583e3ff648bf28339d6c9f0898 Meaning of ThermSenseCoreSel bit was inverted beginning with K8 RevF. That means with current driver temp1/temp2 belong to core 1 and temp3/temp4 belong to core 0 on a K8 RevF/RevG CPU. This patch ensures that temp1/temp2 always belong to core 0 and temp3/temp4 to core 1 for all K8 revisions.

hwmon: (k8temp) Warn about fam F rev F errata 2009-01-15T21:27:46+00:00 Andreas Herrmann andreas.herrmann3@amd.com 2009-01-15T21:27:46+00:00 bb9a35f293a3c8b5d57253cdfe2f29fa2627e1b9 Add warning about wrong CPU temperature readouts on all fam F rev F. The allowed combinations of processors ensure that all processors in a multisocket system have similar characteristics, e.g. (1) provide temperature sensor interface (>=RevC && <RevF) (2) are affected by erratum #141 (>=RevF) Thus it is sufficient to check the revision of the boot CPU. For "mixed silicon support" refer to "Revision Guide for AMD Athlon 64 and AMD Opteron Processors" (RevA-E) and "Revision Guide for AMD NPT Family 0Fh Processors" (RefF-G).
