+ select X86_SPEEDSTEP_CENTRINO_TABLE if X86_32
+ depends on X86_32 || (X86_64 && ACPI_PROCESSOR)
+ help
+ This is deprecated and this functionality is now merged into
+ acpi_cpufreq (X86_ACPI_CPUFREQ). Use that driver instead of
+ speedstep_centrino.
+ This adds the CPUFreq driver for Enhanced SpeedStep enabled
+ mobile CPUs. This means Intel Pentium M (Centrino) CPUs
+ or 64bit enabled Intel Xeons.
+
+ To compile this driver as a module, choose M here: the
+ module will be called speedstep-centrino.
+
+ For details, take a look at <file:Documentation/cpu-freq/>.

+ select CPU_FREQ_TABLE
+ help
+ This adds the CPUFreq driver for Intel Pentium 4 / XEON
+ processors. When enabled it will lower CPU temperature by skipping
+ clocks.
+
+ This driver should be only used in exceptional
+ circumstances when very low power is needed because it causes severe
+ slowdowns and noticeable latencies. Normally Speedstep should be used
+ instead.
+
+ To compile this driver as a module, choose M here: the
+ module will be called p4-clockmod.
+
+ For details, take a look at <file:Documentation/cpu-freq/>.
+
+ Unless you are absolutely sure say N.

+ tristate "VIA C7 Enhanced PowerSaver (DANGEROUS)"
+ select CPU_FREQ_TABLE
+ depends on X86_32 && EXPERIMENTAL
+ help
+ This adds the CPUFreq driver for VIA C7 processors. However, this driver
+ does not have any safeguards to prevent operating the CPU out of spec
+ and is thus considered dangerous. Please use the regular ACPI cpufreq
+ driver, enabled by CONFIG_X86_ACPI_CPUFREQ.
+
+ If in doubt, say N.

+config X86_SPEEDSTEP_RELAXED_CAP_CHECK
+ bool "Relaxed speedstep capability checks"
+ depends on X86_32 && (X86_SPEEDSTEP_SMI || X86_SPEEDSTEP_ICH)
+ help
+ Don't perform all checks for a speedstep capable system which would
+ normally be done. Some ancient or strange systems, though speedstep
+ capable, don't always indicate that they are speedstep capable. This
+ option lets the probing code bypass some of those checks if the
+ parameter "relaxed_check=1" is passed to the module.
