ABSTRACT:
Transaction layer link down handling for Peripheral Component Interconnect (PCI) Express. A link between an input/output (I/O) controller port of an I/O controller and a device port of a device is initialized, wherein the link includes a physical layer, a data link layer, and a transaction layer. The transaction layer is restored after a data link down condition without software intervention.
