123 tristate "'conservative' cpufreq governor"
124 depends on CPU_FREQ
125 help
126 'conservative' - this driver is rather similar to the 'ondemand'
127 governor both in its source code and its purpose, the difference is
128 its optimisation for better suitability in a battery powered
129 environment. The frequency is gracefully increased and decreased
130 rather than jumping to 100% when speed is required.
131
132 If you have a desktop machine then you should really be considering
133 the 'ondemand' governor instead, however if you are using a laptop,
134 PDA or even an AMD64 based computer (due to the unacceptable
135 step-by-step latency issues between the minimum and maximum frequency
136 transitions in the CPU) you will probably want to use this governor.
137
138 For details, take a look at linux/Documentation/cpu-freq.

76# Some sound drivers call gameport functions. If GAMEPORT is

78# well.
79# If GAMEPORT is built in, everything is fine.
80# If GAMEPORT is a module, however, it would need to be loaded for the

82# driver must be a module as well in that case. Since there's no way
83# to express that directly in Kconfig, we use SOUND_GAMEPORT to
84# express it. SOUND_GAMEPORT boils down to "if GAMEPORT is 'm',
