CPU frequency can be changed via files under /sys/devices/system/cpu/cpu0/cpufreq/.
scaling_available_frequencies
scaling_available_governors: could be "conservative ondemand userspace powersave performance", when we want to change the frequency manually, we set it to "userspace".
scaling_cur_freq
scaling_setspeed
ex: sudo sh -c 'echo 2400000 > scaling_setspeed' # set frequency to 2400000(2.4G)
ex: cat scaling_cur_freq # check if the frequency has been changed.
