摘要： In accordance with certain other techniques, doorbell information is received. A doorbell structure address is decoded from the doorbell information. A first protection domain identifier is determined from the doorbell structure address. A resource context of a data structure is determined from the doorbell information. The resource context at the doorbell address is read to determine a second protection domain identifier. The first protection domain identifier and the second protection domain identifier are compared to determine whether to update the resource context of the doorbell structure.

摘要： Provided are techniques for interrupt processing. An Input/Output device determines that an event has occurred. The Input/Output device determines a state of an event data structure. The Input/Output device writes an event entry into the event data structure in response to determining that the event has occurred. After writing the event entry, the Input/Output device determines whether to generate an interrupt or not based on the state of the event data structure.Additionally provided are techniques for interrupt processing in which an I/O device driver determines that an interrupt has occurred. The I/O device driver reads an event entry in an event data structure in response to determining that the interrupt has occurred. The I/O device driver updates a state of a structure state indicator to enable/disable interrupts.

摘要： Provided are a method, system, and program for managing data transmission from a source to a destination through a network. The destination imposes a window value on the source which limits the quantity of data packets which can be sent from the source to the destination without receiving an acknowledgment of being received by the destination. In one embodiment, the source imposes a second window value, smaller than the destination window value, which limits even further the quantity of data packets which can be sent from the source to the destination without receiving an acknowledgment of being received by the destination. In another embodiment, a plurality of direct memory access connections are established between the source and a plurality of specified memory locations of a plurality of destinations. The source imposes a plurality of message limits, each message limit imposing a separate limit for each direct memory access connection on the quantity of messages sent from the source to the specified memory location of the direct memory access connection associated with the message limit and lacking a message acknowledgment of being received by the destination of the direct memory access connection associated with the message limit.

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.

摘要： Provided are techniques for interrupt processing. An Input/Output device determines that an event has occurred. 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.
