             Summary: pci: configuration access capability rules are unclear
                 Key: VIRTIO-145
                 URL: https://issues.oasis-open.org/browse/VIRTIO-145
             Project: OASIS Virtual I/O Device (VIRTIO) TC
          Issue Type: Bug
    Affects Versions: virtio 1.0 cs03
         Environment: Michael S. Tsirkin <>
            Reporter: Michael S. Tsirkin
             Fix For: virtio 1.0 cs04


Specification merely says PCI config access capability
aliases a device BAR. This seems to allow config access to
legacy BAR (for transitional devices) but how should device
interpret such an access?
