   4 Description:
   5                 This attribute indicates the full path of ACPI namespace
   6                 object associated with the device object.  For example,
   7                 \_SB_.PCI0.
   8                 This file is not present for device objects representing
   9                 fixed ACPI hardware features (like power and sleep
  10                 buttons).

  15 Description:
  16                 This attribute indicates the PNP IDs of the device object.
  17                 That is acpi:HHHHHHHH:[CCCCCCC:].  Where each HHHHHHHH or
  18                 CCCCCCCC contains device object's PNPID (_HID or _CID).

  56                 Writing 1 to this attribute will trigger hot removal of
  57                 this device object.  This file exists for every device
  58                 object that has _EJ0 method.
