[Qemu-devel] [PATCH v4] fix pci_requester_id()

[Peter Xu <peterx@redhat.com>]

v4 changes:

Introduced PCIReqIDCache struct. Since PCI bus number may be
changing during time, we need to cache the device that we can fetch
requester_id from. Meanwhile, we need to cache how we should extract
reqid from the cache. Currently there are two kinds:

- BDF: directly fetch BDF from the cached device
- SECONDARY_BUS: this is only used when device are under pcie-to-pci
  bridges.

Thanks,
