[Qemu-devel] [PATCH RFC 0/7] q35: add legacy pci acpi hotplug support

[Marcel Apfelbaum <marcel@redhat.com>]

The series adds hotplug support to legacy PCI buses for Q35 machines.
The ACPI hotplug code is emitted if at least one legacy pci-bridge is present.

It is still RFC because:
 - the compat code is for 2.6 machines
 - it works only for pci-bridge, there are still some issues with i82801b11-bridge
 - needs more testing

The current implementation does not include PCIe Root Port support.

Patches 1-4: various acpi pre-requisites fixes
Patch 5: adds pcihp initialization code to Q35
Patch 6: makes acpi pci hotplug generic by handling PCIe cases
Patch 7: Adds pchihp support to ich9.

Thanks,
Marcel
