It turns out AMD bumped the revision number from 6 to 7, and
powernow-k8 doesn't like that.
At the suggestion of powernow-k8's maintainer (Mark Langsdorf) I
edited line 49 of powernow-k8.h and changed:
#define CPUID_XMOD_REV_G 0x00060000
#define CPUID_XMOD_REV_H 0x00070000
then changed CPUID_XMOD_REV_G in powernow-k8.c to CPUID_XMOD_REV_H
(actually, he just said "bump it to 7", but it seemed logical to
increment the revision letter, too)
This worked, and the cpuspeed daemon lowered the CPU frequency and
voltage when idling.
Anyway, Mark said he'd submitted a patch, but it hadn't made its way
to the main kernel source yet. Is there any chance the Fedora kernel
maintainers might add such a patch to the next kernel?
I've just pushed this to Linus for .22, and will get it into .21-stable too.
We'll pick it up in Fedora through those trees soon.
