When running in a Xen PVH guest, there's nothing to do in PciAcpiInitialization() because there isn't any PCI bus. When the Host Bridge DID isn't recognised, simply continue. (The value of PcdOvmfHostBridgePciDevId would be 0 because it isn't set.)
Ref: https://bugzilla.tianocore.org/show_bug.cgi?id=1689 Signed-off-by: Anthony PERARD <anthony.per...@citrix.com> --- Notes: v3: - Instead of checking for a false value, XEN_PVH_PCI_HOST_BRIDGE_DEVICE_ID, simply check if we are running xen when the HostBridge device ID isn't recognised.
