ACPI spec define that devices can be notified with some well defined values. Handlers from system list are called for notify values within 0-0x7F. In turn, handlers from device list are called for notify value greater than 0x80. Till now only system handler could be called. Now we are able to notify devices with all notify values range that means we can emulate SCI line e.g. to trigger APCI errors.
