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.

help
|
|
This governor implements a simplified idle state selection method
|
|
focused on timer events and does not do any interactivity boosting.
|
|
|
|
Some workloads benefit from using it and it generally should be safe
|
|
to use. Say Y here if you are not happy with the alternatives.
