* hwmon: (k8temp) Fix temperature reporting for (most) K8 RevG CPUsAndreas Herrmann2009-01-151-2/+15
| | | | | | | | | | | | | | | | | | | | | | | | | 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 CPUsAndreas Herrmann2009-01-151-0/+9
| | | | | | | | | | | | | 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 errataAndreas Herrmann2009-01-151-7/+22
| | | | | | | | | | | | | | | | | | | | 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).
