Date:		December 2006

Contact:	Rafael J. Wysocki <rjw@rjwysocki.net>

Description:

		This attribute indicates the full path of ACPI namespace

		object associated with the device object.  For example,

		\_SB_.PCI0.

		This file is not present for device objects representing

		fixed ACPI hardware features (like power and sleep

		buttons).



What:		/sys/bus/acpi/devices/.../modalias

Date:		July 2007

Contact:	Rafael J. Wysocki <rjw@rjwysocki.net>

Description:

		This attribute indicates the PNP IDs of the device object.

		That is acpi:HHHHHHHH:[CCCCCCC:].  Where each HHHHHHHH or

		CCCCCCCC contains device object's PNPID (_HID or _CID).



What:		/sys/bus/acpi/devices/.../hid

Date:		April 2005

Contact:	Rafael J. Wysocki <rjw@rjwysocki.net>

Description:

		This attribute indicates the hardware ID (_HID) of the

		device object.  For example, PNP0103.

		This file is present for device objects having the _HID

		control method.



What:		/sys/bus/acpi/devices/.../description

Date:		October 2012

Contact:	Rafael J. Wysocki <rjw@rjwysocki.net>

Description:

		This attribute contains the output of the device object's

		_STR control method, if present.



What:		/sys/bus/acpi/devices/.../adr

Date:		October 2012

Contact:	Rafael J. Wysocki <rjw@rjwysocki.net>

Description:

		This attribute contains the output of the device object's

		_ADR control method, which is present for ACPI device

		objects representing devices having standard enumeration

		algorithms, such as PCI.



What:		/sys/bus/acpi/devices/.../uid

Date:		October 2012

Contact:	Rafael J. Wysocki <rjw@rjwysocki.net>

Description:

		This attribute contains the output of the device object's

		_UID control method, if present.



What:		/sys/bus/acpi/devices/.../eject

Date:		December 2006

Contact:	Rafael J. Wysocki <rjw@rjwysocki.net>

Description:

		Writing 1 to this attribute will trigger hot removal of

		this device object.  This file exists for every device

		object that has _EJ0 method.
