[In dir /sys/devices/system/cpu/cpu1/cpufreq]
I find
# cat scaling_available_governors
userspace conservative powersave ondemand performance
Ok so trying to set the governor...
# cat scaling_governor
ondemand
# echo userspace > scaling_governor
# cat scaling_governor
userspace
So I can change that. However...
# echo 2400000 > scaling_max_freq
bash: echo: write error: Invalid argument
Even though
# cat scaling_available_frequencies
3000000 2400000
