What: /sys/devices/.../power_state |
|
Date: January 2013 |
|
Contact: Rafael J. Wysocki <[email protected]> |
|
Description: |
|
The /sys/devices/.../power_state attribute is only present for |
|
device objects representing ACPI device nodes that provide power |
|
management methods. |
|
|
|
If present, it contains a string representing the current ACPI |
|
power state of the given device node. Its possible values, |
|
"D0", "D1", "D2", "D3hot", and "D3cold", reflect the power state |
|
names defined by the ACPI specification (ACPI 4 and above). |
|
|
|
If the device node uses shared ACPI power resources, this state |
|
determines a list of power resources required not to be turned |
|
off. However, some power resources needed by the device node in |
|
higher-power (lower-number) states may also be ON because of |
|
some other devices using them at the moment. |
|
|
|
This attribute is read-only.
