Abstract
Contention-based method and system are provided for generating reduced number of interrupts upon completing one or more commands. Each interrupt indicates the availability of data for transfer from a host adapter to a processor. The host adapter is coupled to one or more I/O devices over a bus. One or more I/O commands are received for transferring data between the processor and one or more I/O devices. Then, the contention for the bus among the I/O devices is monitored to determine how many devices are arbitrating for the bus.
