I am trying to set CPU frequency manually, but it doesn’t work!
I follow these instruction from elinux.org:
first I set the governor to userspace without any problem:
echo "userspace" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
, and then I set the frequency to one of the available frequencies, for example 1326000khz:
echo 1326000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed
But then when I check scaling_cur_freq, it still shows the initial value!
Do I need to make some kernel configuration, or is it something else that I am doing wrong? I would appreciate any suggestion.
