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. |

|
help |
|
This governor implements haltpoll idle state selection, to be |
|
used in conjunction with the haltpoll cpuidle driver, allowing |
|
for polling for a certain amount of time before entering idle |
|
state. |
|
|
|
Some virtualized workloads benefit from using it. |

help |
|
This option enables halt poll cpuidle driver, which allows to poll |
|
before halting in the guest (more efficient than polling in the |
|
host via halt_poll_ns for some scenarios). |
