    摘要: A method and apparatus for advancing initialization messages in a lock-step manner when initializing an interface is presented. In one embodiment, a lane receiver may transition to a receiver ready attribute when a given number of current training sequence messages is correctly received. When the receiver ready attributes of all the lanes are set, a local acknowledgement attribute may be set. Similarly, a lane receiver may transition to a remote acknowledgement attribute when a given number of current training sequence messages with acknowledgement field set is correctly received. When both the local acknowledgement attribute and the remote acknowledgement attribute are set, the port may advance to the next training sequence messages.

    摘要: A software self test engine is executed from a cache of a processor. The software self test engine is executed using an execution engine of the processor to perform a physical layer self test. The physical layer self test is performed by transmitting a test vector from the execution engine under control of the self test engine to an input/output (“I/O”) unit of the processor along a datapath coupling the execution engine to the I/O unit. The test vector is transmitted along a loop back path including the I/O unit and the datapath to test a hardware device along the loop back path.

    摘要: A method and apparatus for advancing initialization messages when initializing an interface is presented. In one embodiment, one of a sequence of training sequence messages are sent in serial mode across the data lanes of a generally-parallel interface between two agents. When one agent correctly receives a fixed number of messages, it may begin sending its messages with an acknowledgement. Thereafter, when that agent correctly receives a fixed number of messages including an acknowledgement, that agent may advance to sending the next training sequence messages in the sequence.
