[Qemu-devel] [PATCH 0/7] pci: Create PCI Express bus type

[Alex Williamson]

When setting PCIe capabilities we need to know the type of bus we
have.  On secondary buses we could poke around on the parent bridge
device to infer this data, but on root buses there's no parent device.
By creating a new PCIE TypeInfo we can inherit everything about PCI
buses while still allowing us to differentiate and potentially extend
in the future.

The first benefactor of this change is included here, mangling
Endpoints to Root Complex Integrated Endpoints, allowing nec-usb-xhci
to work on the root bus of q35 with Windows.  I also plan to use this
to drop link capabilities, control, and status on all Integrated
Endpoints and for PCIe capability modifications on assigned devices.
Thanks,

Alex
