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.
config CPU_IDLE_GOV_TEO bool"Timer events oriented (TEO) governor (for tickless systems)"
help This governor implements a simplified idle state selection method
focused on timer events and does notdo 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.
config CPU_IDLE_GOV_HALTPOLL bool"Haltpoll governor (for virtualized systems)"
depends on KVM_GUEST
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.

host via halt_poll_ns for some scenarios).
