GED is modelled as a device +in the namespace with a _HID defined to be ACPI0013. This document +describes the interface between QEMU and the ACPI BIOS. + +GED allows HW reduced platforms to handle interrupts in ACPI ASL +statements. It follows a very similar approach to the _EVT method +from GPIO events. All interrupts are listed in _CRS and the handler +is written in _EVT method. However, the QEMU implementation uses a +single interrupt for the GED device, relying on an IO memory region +to communicate the type of device affected by the interrupt.
