摘要： A system and method for asynchronously managing the issuance of program I/O store instructions from a high speed central processor to a multiplicity of relatively lower speed I/O adapter devices. An interface between the central processor and the I/O adapter devices includes a program I/O store queue, a state machine, and a token pool related in count to the concurrent processing capabilities of I/O controllers. The interface queue includes information for uniquely identifying program I/O store instructions by adapter device destination and user application program to manage error recovery. As preferably implemented, the interface system and method also distinctly manages program I/O instructions requiring synchronous execution, such as program I/O load instructions.

摘要： A method and system for transmitting packets. Packets may be transmitted when a protocol control block is copied from a host processing system to a network protocol offload engine. Message information that contains packet payload addresses may be provided to the network protocol offload engine to generate a plurality of message contexts in the offload engine. With the message contexts, protocol processing may be performed at the offload engine while leaving the packet payload in the host memory. Thus, packet payloads may be transmitted directly from the host memory to a network communication link during transmission of the packets by the offload engine. Other embodiments are also described.

The Input/Output device determines a processor identifier and determines an event data structure identifier for an event data structure into which data for the event is stored using the processor identifier. The Input/Output device also determines a vector identifier for an interrupt message vector into which an interrupt message for the event is written. Then, interrupt message data is written to the interrupt message vector to generate an interrupt.
