ABSTRACT:
A virtual PCI Express device1600indicates the presence of a pseudo I/O device in a PCI Express initial configuration cycle to reserve a resource space for a device anticipated to be installed in the future, and when an I/O device1400is inserted into an unoccupied slot1605, a virtual PCI Express device control logic1602notifies a downstream PCI-PCI bridge1504via a hot-plugging control line1601, and the downstream PCI-PCI bridge1504generates an interrupt to a CPU1100to notify it of insertion of the I/O device1400in conformance with the procedure for hot plugging defined by the PCI-SIG Standards, and configuration software1000invoked configures the inserted I/O device1400.
