    • 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.
    • 提供了用于中断处理的技术。 输入/输出设备确定事件已发生。 输入/输出设备确定事件数据结构的状态。 响应于确定事件已经发生,输入/输出设备将事件条目写入事件数据结构。 在写入事件条目之后,输入/输出设备根据事件数据结构的状态确定是否产生中断。 另外提供了用于中断处理的技术,其中I / O设备驱动器确定已经发生中断。 I / O设备驱动程序响应于确定已经发生中断而在事件数据结构中读取事件条目。 I / O设备驱动程序更新结构状态指示灯的状态以启用/禁用中断。

    • 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.
    • 提供了一种用于管理通过网络从源到目的地的数据传输的方法,系统和程序。 目的地在源上施加窗口值,其限制可以从源向目的地发送的数据分组的数量,而不接收目的地接收的确认。 在一个实施例中,源施加小于目的地窗口值的第二窗口值,其进一步限制可以从源向目的地发送的数据分组的数量,而不接收目的地接收的确认。 在另一个实施例中,在多个目的地的源和多个指定的存储器位置之间建立多个直接存储器访问连接。 来源强加多个消息限制,每个消息限制对于从源发送到与消息限制相关联的直接存储器访问连接的指定存储器位置的消息数量对每个直接存储器访问连接施加单独的限制,并且缺少 与消息限制相关联的直接存储器访问连接的目的地接收到的消息确认。
