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. |
