3 Supporting multiple CPU idle levels in kernel
10 cpuidle driver hooks into the cpuidle infrastructure and handles the
11 architecture/platform dependent part of CPU idle states. Driver
12 provides the platform idle state detection capability and also
13 has mechanisms in place to support actual entry-exit into CPU idle states.
15 cpuidle driver initializes the cpuidle_device structure for each CPU device
16 and registers with cpuidle using cpuidle_register_device.
18 It can also support the dynamic changes (like battery <-> AC), by using
19 cpuidle_pause_and_lock, cpuidle_disable_device and cpuidle_enable_device,
20 cpuidle_resume_and_unlock.
