Abstract
A method and system for requesting an interrupt from a host system to service an adapter connected to the host system and a data interface. Data packets, including one or more data cells, are transferred between the data interface and the host system. The host system includes a host memory that includes a plurality of memory slots to store data packets transferred between the data interface and the host system. It is determined when a transfer of data has resulted in an occurrence of an interrupt event. An interrupt event occurs when the transfer of data includes a transfer of a data cell between the data interface and the host system and the data cell is defined to be an end of a data packet. In response to the occurrence of an interrupt event, it is determined whether to generate an interrupt request to the host system. This step of determining includes determining whether a predetermined interval of time has elapsed since the host system last processed an interrupt request or determining whether a predetermined number of interrupt events have occurred since the host system last processed an interrupt request. If the predetermined interval of time has elapsed or the predetermined…
