config CPU_FREQ
	bool "CPU Frequency scaling"
	help
	  CPU Frequency scaling allows you to change the clock speed of 
	  CPUs on the fly. This is a nice method to save power, because 
	  the lower the CPU clock speed, the less power the CPU consumes.

	  Note that this driver doesn't automatically change the CPU
	  clock speed, you need to either enable a dynamic cpufreq governor
	  (see below) after boot, or use a userspace tool.

	  For details, take a look at <file:Documentation/cpu-freq>.

	  If in doubt, say N.

config CPU_FREQ_DEBUG
	bool "Enable CPUfreq debugging"
	help
	  Say Y here to enable CPUfreq subsystem (including drivers)
	  debugging. You will need to activate it via the kernel
	  command line by passing
	     cpufreq.debug=<value>

	  To get <value>, add 
	       1 to activate CPUfreq core debugging,
	       2 to activate CPUfreq drivers debugging, and
	       4 to activate CPUfreq governor debugging

	  This driver exports CPU frequency statistics information through sysfs

	  To compile this driver as a module, choose M here: the

	  This option sets which CPUFreq governor shall be loaded at
	  startup. If in doubt, select 'performance'.

config CPU_FREQ_DEFAULT_GOV_PERFORMANCE
	bool "performance"
	select CPU_FREQ_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

	  program shall be able to set the CPU dynamically without having
	  to enable the userspace governor manually.

config CPU_FREQ_DEFAULT_GOV_ONDEMAND

	select CPU_FREQ_GOV_ONDEMAND
	select CPU_FREQ_GOV_PERFORMANCE
	help
	  Use the CPUFreq governor 'ondemand' as default. This allows
	  you to get a full dynamic frequency capable system by simply
	  loading your cpufreq low-level hardware driver.
	  Be aware that not all cpufreq drivers support the ondemand
	  governor. If unsure have a look at the help section of the
	  driver. Fallback governor will be the performance governor.

	  Enable this cpufreq governor when you either want to set the

	  be able to set the CPU dynamically, like on LART 
	  <http://www.lartmaker.nl/>.

config CPU_FREQ_GOV_ONDEMAND
	tristate "'ondemand' cpufreq policy governor"
	select CPU_FREQ_TABLE
	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). 

	  To compile this driver as a module, choose M here: the
	  module will be called cpufreq_ondemand.

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

	  If in doubt, say N.

config CPU_FREQ_GOV_CONSERVATIVE
	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.

	  To compile this driver as a module, choose M here: the
	  module will be called cpufreq_conservative.

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

	  If in doubt, say N.
