Here an example with idle desktop, scaling driver "intel_pstate":
cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
powersave
powersave
powersave
powersave
$ cat /proc/cpuinfo | grep -i mhz
cpu MHz : 1632.000
cpu MHz : 1632.000
cpu MHz : 1666.000
cpu MHz : 1666.000
# cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq
1666000
1598000
1666000
1666000
Now s2ram + resume:
cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
powersave
powersave
powersave
powersave
cat /proc/cpuinfo | grep -i mhz
cpu MHz : 3060.000
cpu MHz : 1598.000
cpu MHz : 3366.000
cpu MHz : 1598.000
cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq
1598000
2652000
3264000
1598000
I even noticed once that after resume only core0 was on "powersave"
while core 1,2,3 were on "performance".
This has also been reported with kernel 3.10-rcX in Gentoo:
http://comments.gmane.org/gmane.linux.kernel.cpufreq/11000
and a fix/patch was published here:
