In linux kernel since version 3.10 (release Date: 2013-06-30)
'conservative' - this driver is rather similar to the 'ondemand'
governor both in its source code and its purpose, the difference is
its optimisation for better suitability in a battery powered
environment. The frequency is gracefully increased and decreased
rather than jumping to 100% when speed is required.
If you have a desktop machine then you should really be considering
the 'ondemand' governor instead, however if you are using a laptop,
PDA or even an AMD64 based computer (due to the unacceptable
step-by-step latency issues between the minimum and maximum frequency
transitions in the CPU) you will probably want to use this governor.
To compile this driver as a module, choose M here: the
module will be called cpufreq_conservative.
For details, take a look at

If in doubt, say N.
