摘要：
A method and circuitry for reconfiguring the links of a PCI Express bus after a user hot swaps a PCI device. A computer system has been initially configured with PCI Express bus links to various endpoints, using the scaling features of the PCI Express standard. If a hot swap occurs, an SMI routine is used to signal a reconfiguration circuit to reroute unused links (or unused portions of links) to one or more other PCI devices.
