This is a standard PCI root bus (not a bridge) that can be added to a 440fx-based domain. Although it uses a PCI slot, this is *not* how it is connected into the PCI bus hierarchy, but is only used for control. Each pci-expander-bus provides 32 slots (0-31) that can accept hotplug of standard PCI devices. The usefulness of pci-expander-bus relative to a pci-bridge is that the NUMA node of the bus can be specified with the <node> subelement of <target>. This gives guest-side visibility to the NUMA node of attached devices (presuming that management apps only assign a device to a bus that has a NUMA node number matching the node number of the device on the host). Each pci-expander-bus also has a "busNr" attribute. The expander-bus itself will take the busNr specified, and all buses that are connected to this bus (including the pci-bridge that is automatically added to any expander bus of model "pxb" (see the next commit)) will use busNr+1, busNr+2, etc, and the pci-root (or the expander-bus with next lower busNr) will use bus numbers lower than busNr. |
