Also, there used to be an “ondemand” governor, which is no longer listed in /sys/devices/system/cpu/cpu?/cpufreq/scaling_available_governors.
For laptops and other battery-powered devices, ‘conservative’ is preferred over ‘ondemand’. It's probably a sane default choice for all.
Was it removed or are we just missing a kconfig option?
