There are following CPUID checks necessary in k8temp: >= K8 RevC to check for support of temperature reporting at all. >= RevF to check for erratum #141 >= RevG (desktop) to check for temperature skew (In the future we might have additional checks for family 0x10 >= RevC to check for erratum 319.) This devides K8 CPUs into 4 classes (and family 10h CPUs into 2 classes). Now it is important to notice that (by chance) you can't combine processors of different classes in a mixed silicon setup. See the relevant CPU revision guides for those CPUs. E.g., combining RevC with RevF is not supported. Thus it suffices to check CPUID of boot CPU. We don't need to care about unsupported processor combinations. Regards, Andreas
