CONFIG_X86_SPEEDSTEP_CENTRINO: Intel Enhanced SpeedStep (deprecated)

General informations

The Linux kernel configuration item CONFIG_X86_SPEEDSTEP_CENTRINO has multiple definitions:

Intel Enhanced SpeedStep (deprecated) found in arch/x86/kernel/cpu/cpufreq/Kconfig

The configuration item CONFIG_X86_SPEEDSTEP_CENTRINO:

Help text

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 Documentation/cpu-freq/.

If in doubt, say N.

Help text

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.
