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 an ACPI-enabled platform, you should say Y here.

Allows the cpuidle framework to use different drivers for each CPU.
|
|
This is useful if you have a system with different CPU latencies and
|
|
states. If unsure say N.
