turbostat.c
FYI, I've updated the utility above, now named "turbostat".
It is now slightly less dumb, checking cpuid and more counters.
Here is an example of a 2.93Ghz Nehalem running at 3.17GHz
(No package C-states enabled on this BIOS/stepping)
r...@nehalem lenb]# ./turbostat
Nehalem multiplier 22, TSC frequency 2933 MHz
Nehalem 4 cores active: 23 mult, max turbo frequency = 3067 MHz
Nehalem 3 cores active: 23 mult, max turbo frequency = 3067 MHz
Nehalem 2 cores active: 23 mult, max turbo frequency = 3067 MHz
Nehalem 1 core active: 24 mult, max turbo frequency = 3200 MHz
