Supporting multiple CPU idle levels in kernel
|
|
|
|
cpuidle
|
|
|
|
General Information:
|
|
|
|
Various CPUs today support multiple idle levels that are differentiated
|
|
by varying exit latencies and power consumption during idle.
|
|
cpuidle is a generic in-kernel infrastructure that separates
|
|
idle policy (governor) from idle mechanism (driver) and provides a
|
|
standardized infrastructure to support independent development of
|
|
governors and drivers.
|
|
|
|
cpuidle resides under drivers/cpuidle.
|
|
|
|
Boot options:
|
|
"cpuidle_sysfs_switch"
|
|
enables current_governor interface in /sys/devices/system/cpu/cpuidle/,
|
|
which can be used to switch governors at run time. This boot option
|
|
is meant for developer testing only. In normal usage, kernel picks the
|
|
best governor based on governor ratings.
