The PXB host bridge provides a way to have multiple PCI hierarchies (PCI root
buses).
This series is porting the PXB device to Q35 machines by:
- removing the internal pci-bridge
- make the PXB bus PCIe for Q35, while it remains PCI for i440fx.
This approach works because the Root Complexes are exposed to guest as regular
(legacy) opaque PCI host bridges.
Tested on Fedora and Windows guests with both Root Ports and PCIe Switches.
v1 -> v2:
Addressed Gerd Hoffmann comments:
- Added x-enable-internal-bridge compat property to keep the PCI
bridge for older machine to avoid breaking migration.
Thanks,
Marcel
Marcel Apfelbaum (4):
hw/pxb: remove the built-in pci bridge
hw/acpi: merge pxb adjacent memory/IO ranges
hw/pc: query both q35 and i440fx bus
hw/pxb: add support for PCIe
