CONFIG_X86_SPEEDSTEP_CENTRINO_ACPI: Use ACPI tables to decode valid frequency/voltage pairs

General informations

The Linux kernel configuration item CONFIG_X86_SPEEDSTEP_CENTRINO_ACPI has multiple definitions:

found in arch/x86_64/kernel/cpufreq/Kconfig

The configuration item CONFIG_X86_SPEEDSTEP_CENTRINO_ACPI:

(none)

Use ACPI tables to decode valid frequency/voltage (deprecated) found in arch/i386/kernel/cpu/cpufreq/Kconfig

The configuration item CONFIG_X86_SPEEDSTEP_CENTRINO_ACPI:

Help text

This is deprecated and this functionality is now merged into acpi_cpufreq (X86_ACPI_CPUFREQ). Use that driver instead of speedstep_centrino. 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.
