      1QEMU<->ACPI BIOS PCI hotplug interface
      2======================================
      3
      4QEMU supports PCI hotplug via ACPI, for PCI bus 0. This document
      5describes the interface between QEMU and the ACPI BIOS.
      6
      7ACPI GPE block (IO ports 0xafe0-0xafe3, byte access)
      8----------------------------------------------------
      9
     10Generic ACPI GPE block. Bit 1 (GPE.1) used to notify PCI hotplug/eject
     11event to ACPI BIOS, via SCI interrupt.
     12
     13PCI slot injection notification pending (IO port 0xae00-0xae03, 4-byte access)
     14------------------------------------------------------------------------------
     15
     16Slot injection notification pending. One bit per slot.
     17
     18Read by ACPI BIOS GPE.1 handler to notify OS of injection
     19events.  Read-only.
     20
     21PCI slot removal notification (IO port 0xae04-0xae07, 4-byte access)
     22--------------------------------------------------------------------
     23
     24Slot removal notification pending. One bit per slot.
     25
     26Read by ACPI BIOS GPE.1 handler to notify OS of removal
     27events.  Read-only.
     28
     29PCI device eject (IO port 0xae08-0xae0b, 4-byte access)
     30-------------------------------------------------------
     31
     32Write: Used by ACPI BIOS _EJ0 method to request device removal.
     33One bit per slot.
     34
     35Read: Hotplug features register.  Used by platform to identify features
     36available.  Current base feature set (no bits set):
     37
     38- Read-only "up" register @0xae00, 4-byte access, bit per slot
     39- Read-only "down" register @0xae04, 4-byte access, bit per slot
     40- Read/write "eject" register @0xae08, 4-byte access,
     41  write: bit per slot eject, read: hotplug feature set
     42- Read-only hotplug capable register @0xae0c, 4-byte access, bit per slot
     43
     44PCI removability status (IO port 0xae0c-0xae0f, 4-byte access)
     45--------------------------------------------------------------
     46
     47Used by ACPI BIOS _RMV method to indicate removability status to OS. One
     48bit per slot.  Read-only.
