Subject: [PATCH 2.6.25] ACPI: enable CPU_IDLE by default on ACPI systems
Date: Mon, 19 Nov 2007 22:15:24 -0500 [thread overview]
Message-ID: <200711192215.24748.lenb@kernel.org> (raw)
In Linux-2.6.24, CPU_IDLE went upstream, default =n.
For Linux-2.6.25, enable it by default on ACPI systems.
For Linux-2.6.26, we plan to enable it always on ACPI systems.

config CPU_IDLE
bool "CPU idle PM support"
+ default ACPI
help
CPU idle is a generic framework for supporting software-controlled
idle processor power management. It includes modular cross-platform
governors that can be swapped during runtime.
- If you're using a mobile platform that supports CPU idle PM (e.g.
- an ACPI-capable notebook), you should say Y here.
+ If you're using an ACPI-enabled platform, you should say Y here.
