Example ASL for _FIX usage:
Scope(\_SB) {
Device(PCI0) {
Name(_HID, EISAID("PNP0A03"))
Method (_CRS,0){
}
Name(_PRT, Package(){
})
Name(_FIX, Package(1) {
EISAID("PNP0C25")}
)
// Root PCI Bus
// Need _HID for root device
// Need current resources for root device
// Return current resources for root bridge 0
// Need PCI IRQ routing for PCI bridge
// Package with PCI IRQ routing table information
// PM2 control ID
Device (PX40) {
// ISA
Name(_ADR,0x00070000)
Name(_FIX, Package(1) {
EISAID("PNP0C20")}
// SMI command port
)
Device (NS17) {
// NS17 (Nat. Semi 317, an ACPI part)
Name(_HID, EISAID("PNP0C02"))
Name(_FIX, Package(3) {
EISAID("PNP0C22"), // PM1b event ID
EISAID("PNP0C24"), // PM1b control ID

6.2.7 _GSB (Global System Interrupt Base)
_GSB is an optional object that evaluates to an integer that corresponds to the Global System
Interrupt Base for the corresponding I/O APIC device. The I/O APIC device may either be bus
enumerated (e.g. as a PCI device) or enumerated in the namespace as described in Section 9.17,”I/O
