+/**
+ *
+ * Meaning of fields reported by the event according to the ACPI standard:
+ * @source:
+ *  0x00 - 0xff: Notification values, as passed at the request time
+ *  0x100: Operating System Shutdown Processing
+ *  0x103: Ejection processing
+ *  0x200: Insertion processing
+ *  other values are reserved
+ *
+ * @status:
+ *   general values
+ *     0x00: success
+ *     0x01: non-specific failure
+ *     0x02: unrecognized notify code
+ *     0x03 - 0x7f: reserved
+ *     other values are specific to the notification type
+ *
+ *   for the 0x100 source the following additional codes are standardized
+ *     0x80: OS Shutdown request denied
+ *     0x81: OS Shutdown in progress
+ *     0x82: OS Shutdown completed
+ *     0x83: OS Graceful shutdown not supported
+ *     other values are reserved
+ *
+ * Other fields and semantics are specific to the qemu handling of the event.
+ *  - @alias may be NULL for successful unplug operations
+ *  - @slotType describes the device type a bit more closely, currently the
+ *    only known value is 'DIMM'
+ *  - @slot describes the specific device
+ *
+ *  Note that qemu does not emit the event for all the documented sources or
+ *  devices.
