CPU_FREQ_GOV_CONSERVATIVE — "Conservative" CPUFreq policy governor
This driver is similar to the Ondemand governor both in its source code and its purpose. The difference is that the Conservative governor is optimiaed for a battery-powered system. The frequency is gracefully increased and decreased rather than jumping to 100% when speed is required.
If you are using a laptop, a PDA, or 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. If you have a desktop machine, consider the Ondemand governor instead.
For details, take a look at Documentation/cpu-freq.
