Abstract: A method, apparatus, and system are disclosed. In one embodiment the method comprises transmitting Peripheral Component Interconnect (PCI) Express protocol data on a first set of one or more lanes of a link and concurrently transmitting non-PCI Express protocol data on a second set of one or more lanes of the link.

Abstract: In some embodiments, the inventions include a chip having a status register circuit coupled to conductors to receive interrupt event signals to provide source signals corresponding to the interrupt event signals. The chip also includes a control register circuit to provide source enable signals for selective ones of the interrupt sources, and a re-arming logic circuit coupled to the conductors to receive the interrupt event signals and provide a re-arming signal. The chip further includes first logic circuit to receive the source signals, the source enable signals, and the re-arming signal to provide an initial interrupt signal, and message signaled interrupt (MSI) signal pulse generation logic to receive the initial interrupt signal and provide an MSI signal in response thereto. Other embodiments are described and claimed.

Abstract: A memory controller hub includes a graphics subsystem adapted to perform graphics operations on data, and interface circuitry adapted selectively to couple the graphics subsystem to a local memory through electrical connectors and to couple the memory controller hub to a graphics controller through the electrical connectors.
