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.

|
|
+ deepest state that meets all of the following constraints: BM activity,
|
|
+ expected time until next timer interrupt, and last break event time
|
|
+ delta. It is designed to minimize power consumption. Currently
