+ tristate "'conservative' cpufreq governor"
+ depends on CPU_FREQ
+ help
+ '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.
+
+ For details, take a look at linux/Documentation/cpu-freq.
+
+ If in doubt, say N.
