Hi everybody,
recently I was wondering if Cool & Quiet of my Athlon64 3200+ is working correctly on linux. /proc/cpuinfo shows me about 800 MHz cpu speed when the system is idle and about 2000 MHz under load. So my question is whether this information is enough to tell that Cool & Quiet is working.
The board is a Gigabyte K8N Pro with bios version F11, cpu stepping is 8. On Gigabyte's website I found no hint that Cool & Quiet is actually supposed to work, so I didn't try it on windoze. But, hey, on linux (SuSE 9.1 Pro) it works out of the box as it seems.
Am I right, or does /proc/cpuinfo only show what speed the processor is supposed to run at and not what it is currently running?
Here is some more information from /sys/devices/system/cpu/cpu0/cpufreq:
for i in *; do echo $i; cat $i; done ==> cpuinfo_max_freq 2000000 cpuinfo_min_freq 800000 scaling_available_frequencies 2000000 1800000 800000 scaling_available_governors userspace performance scaling_driver powernow-k8 scaling_governor userspace scaling_max_freq 2000000 scaling_min_freq 800000 scaling_setspeed 800000
Cheers, Roger

Yes, that's enough to tell.
