+QEMU<->ACPI BIOS PCI hotplug interface
+======================================
+
+QEMU supports PCI hotplug via ACPI, for PCI bus 0. This document describes the
+interface between QEMU and the ACPI BIOS.
+
+ACPI GPE block (IO ports 0xafe0-0xafe3, byte access)
+----------------------------------------------------
+
+Generic ACPI GPE block. Bit 1 (GPE.1) used to notify PCI hotplug/eject event to
+ACPI BIOS, via SCI interrupt.
+
+PCI slot injection notification pending (IO port 0xae00-0xae03, 4-byte access)
+------------------------------------------------------------------------------
+
+Slot injection notification pending. One bit per slot.
+
+Read by ACPI BIOS GPE.1 handler to notify OS of injection events.
+
+PCI slot removal notification (IO port 0xae04-0xae07, 4-byte access)
+--------------------------------------------------------------------
+
+Slot removal notification pending. One bit per slot.
+
+Read by ACPI BIOS GPE.1 handler to notify OS of removal events.
+
+PCI device eject (IO port 0xae08-0xae0b, 4-byte access)
+-------------------------------------------------------
+
+Used by ACPI BIOS _EJ0 method to request device removal. One bit per slot.
+
+Reads return 0.
+
+PCI removability status (IO port 0xae0c-0xae0f, 4-byte access)
+--------------------------------------------------------------
+
+Used by ACPI BIOS _RMV method to indicate removability status to OS. One bit
+per slot.
