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