    摘要: A requesting device and a completer device are coupled via a high-speed serial interface within a computer system. The requesting device transmits a packet for a request transaction to a completer device. The completer device checks for error conditions in the course of servicing the request. If an error condition is found then the completer device transmits a completion packet with a completion status of something other than successful. The completion packet includes a completer identification field. The requesting device records the completer identification value and indicates in a register that a completion packet has been received with a non-successful completion status.

    摘要: To reduce prefetch overshoot when prefetching partial data sets along the path from input-output bus to system memory, a prefetch field is used to communicate the amount of data that a prefetching entity upstream may prefetch. Utilizing a prefetch field in such a manner reduces the fetching of unneeded data past the end of the requested data, resulting in overall increased system performance.

    摘要: In various embodiments, the present invention includes a method for receiving a transaction having first header information from a first peer device at a first agent of a coherent system, inserting second header information onto the transaction, and routing the transaction to a second peer device using the second header information. In one such embodiment, the first header may be a header of a first protocol and the second header may be of a different protocol that is used to tunnel the transaction through the coherent system.
