摘要： An interrupt notification block stored in host memory is disclosed that contains an image of the interrupt condition contents that may be stored in a host attention register in a host interface port. The interrupt notification block is written by the host interface port and pre-fixed into the port pointer array of a host at the time the host interface port updates the pointers stored in a port pointer array in host memory. The host may then read the interrupt notification block to determine how to process a response or an interrupt rather than having to read the host attention register in the host interface port across the host bus.

摘要： A loop network hub including a hub port with a loop initialization insertion mechanism. The loop initialization insertion mechanism causes a hub port which detects a new node port connection to automatically begin generating loop initialization data. A hub port continues to generate loop initialization data until that hub port receives a loop initialization sequence. The loop initialization data propagates around the loop of the hub, halting ordinary processing. In this way, the entire loop is cleared. Upon receiving a loop initialization sequence, the hub port originating the loop initialization data inserts the new node port into the loop. At this point, loop initialization begins and each node port in the loop network obtains a unique loop network address.

摘要： A 32-word command IOCB format is disclosed. A conventional 8-word format is supported, although in both cases 32-word command IOCBs are used. When the conventional 8-word format is used, the host sets the LE bit=1 and writes a conventional 8-word command IOCB into words 0-7 of the 32-word command IOCB. The firmware performs a DMA operation and reads the LE bit. With the LE bit=1, the firmware knows to read only words 0-7. When the new 32-word format is used, the host sets the LE bit=0 and writes a 32-word IOCB command into the 32-word command IOCB, including command and response buffer pointers, one or more data buffer pointers, and perhaps the command buffer. The firmware performs a DMA operation and reads the LE bit. With the LE bit=0, the firmware knows to read all 32 words of the command IOCB.
