CONFIG_X86_SPEEDSTEP_CENTRINO_ACPI: Use ACPI tables to decode valid frequency/voltage (deprecated)

General informations

The Linux kernel configuration item CONFIG_X86_SPEEDSTEP_CENTRINO_ACPI has multiple definitions:

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:

• prompt: Use ACPI tables to decode valid frequency/voltage (deprecated)
• type: bool
• depends on: ( CONFIG_X86_SPEEDSTEP_CENTRINO && CONFIG_ACPI_PROCESSOR ) && (!( CONFIG_X86_SPEEDSTEP_CENTRINO = CONFIG_y && CONFIG_ACPI_PROCESSOR = CONFIG_m ))
• defined in arch/i386/kernel/cpu/cpufreq/Kconfig
• found in Linux kernels: 2.6.20–2.6.22

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.
