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):
------------------------------------------
+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):
----------------------------------------------------------------
+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. Read-only.
-PCI slot removal notification (IO port 0xae04-0xae07, 4-byte access):

Write: Used by ACPI BIOS _EJ0 method to request device removal.
One bit per slot.
Read: Hotplug features register. Used by platform to identify features
available. Current base feature set (no bits set):
- - Read-only "up" register @0xae00, 4-byte access, bit per slot
- - Read-only "down" register @0xae04, 4-byte access, bit per slot
- - Read/write "eject" register @0xae08, 4-byte access,
- write: bit per slot eject, read: hotplug feature set
- - Read-only hotplug capable register @0xae0c, 4-byte access, bit per slot
-PCI removability status (IO port 0xae0c-0xae0f, 4-byte access):

+- Read-only "up" register @0xae00, 4-byte access, bit per slot
