Abstract:
Virtual PCI bus appears from the perspective of a computer program to be a part of a physical hierarchical PCI bus structure residing behind a host-to-PCI bridge. Devices that are physically located on the host bus side of the host-to-PCI bridge may appear as virtual devices residing on the virtual PCI bus allowing the physical devices to participate in device independent initialization and system resource allocation generally available only to PCI compliant devices. Processor initiated host bus cycles targeted to the virtual PCI device may be intercepted and redirected to the physical device.
