	  This enables the /proc/cpufreq interface for controlling

	  interface instead (which is built automatically).

	  This option sets which CPUFreq governor shall be loaded at

config CPU_FREQ_DEFAULT_GOV_PERFORMANCE

	help
	  Use the CPUFreq governor 'performance' as default. This sets
	  the frequency statically to the highest frequency supported by
	  the CPU.

config CPU_FREQ_DEFAULT_GOV_USERSPACE
	bool "userspace"
	select CPU_FREQ_GOV_USERSPACE
	help
	  Use the CPUFreq governor 'userspace' as default. This allows
	  you to set the CPU frequency manually or when an userspace 
	  program shall be able to set the CPU dynamically without having
	  to enable the userspace governor manually.

	  This cpufreq governor sets the frequency statically to the
	  highest available CPU frequency.

	  Enable this cpufreq governor when you either want to set the

	depends on SYSCTL
	help
	  This enables the /proc/sys/cpu/ sysctl interface for controlling
	  the CPUFreq,"userspace" governor. This is the same interface
	  as known from the 2.4.-kernel patches for CPUFreq, and offers
	  the same functionality as long as "userspace" is the
	  selected governor for the specified CPU.
	
	  For details, take a look at <file:Documentation/cpu-freq/>.

	  If in doubt, say N.

config CPU_FREQ_GOV_ONDEMAND
	tristate "'ondemand' cpufreq policy governor"
	depends on CPU_FREQ
	help
	  'ondemand' - This driver adds a dynamic cpufreq policy governor.
	  The governor does a periodic polling and 
	  changes frequency based on the CPU utilization.
	  The support for this governor depends on CPU capability to
	  do fast frequency switching (i.e, very low latency frequency
	  transitions). 

	  For details, take a look at linux/Documentation/cpu-freq.

	  If in doubt, say N.
