config X86_ACPI_CPUFREQ
	tristate "ACPI Processor P-States driver"
	select CPU_FREQ_TABLE
	depends on ACPI_PROCESSOR
	help
	  This driver adds a CPUFreq driver which utilizes the ACPI
	  Processor Performance States.

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

	  If in doubt, say N.

config ELAN_CPUFREQ
	tristate "AMD Elan SC400 and SC410"
	select CPU_FREQ_TABLE
	depends on X86_ELAN
	---help---
	  This adds the CPUFreq driver for AMD Elan SC400 and SC410
	  processors.

	  You need to specify the processor maximum speed as boot
	  parameter: elanfreq=maxspeed (in kHz) or as module
	  parameter "max_freq".

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

	  If in doubt, say N.

config SC520_CPUFREQ
	tristate "AMD Elan SC520"
	select CPU_FREQ_TABLE
	depends on X86_ELAN
	---help---
	  This adds the CPUFreq driver for AMD Elan SC520 processor.

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

	  If in doubt, say N.


config X86_POWERNOW_K6

	  This adds the CPUFreq driver for Enhanced SpeedStep enabled
	  mobile CPUs.  This means Intel Pentium M (Centrino) CPUs. However,
	  you also need to say Y to "Use ACPI tables to decode..." below
	  [which might imply enabling ACPI] if you want to use this driver
	  on non-Banias CPUs.

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

	  If in doubt, say N.

config X86_SPEEDSTEP_CENTRINO_ACPI

	default y
	help
	  Use primarily the information provided in the BIOS ACPI tables
	  to determine valid CPU frequency and voltage pairings. It is
	  required for the driver to work on non-Banias CPUs.

	  If in doubt, say Y.

config X86_SPEEDSTEP_CENTRINO_TABLE
	bool "Built-in tables for Banias CPUs"
	depends on X86_SPEEDSTEP_CENTRINO
