Description:
|
|
A power zone is a single or a collection of devices, which can
|
|
be independently monitored and controlled. A power zone sysfs
|
|
entry is qualified with the name of the <control type>.

Description:
|
|
Power zones may be organized in a hierarchy in which child
|
|
power zones provide monitoring and control for a subset of
|
|
devices under the parent. For example, if there is a parent
|
|
power zone for a whole CPU package, each CPU core in it can
|
|
be a child power zone.
