H A D | k8temp.c | bb9a35f2 Thu Jan 15 15:27:46 CST 2009 Andreas Herrmann <andreas.herrmann3@amd.com> hwmon: (k8temp) Warn about fam F rev F errata
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).
