Ultimately the driver has to feed back to the f/w's request 74 * queue a sequence of CTIOs (continue target I/O) that describe data to 75 * be moved and/or status to be sent) and finally finishing with sending 76 * to the f/w's response queue an ATIO which then completes the handshake 77 * with the f/w for that command. There's a lot of variations on this theme, 78 * including flags you can set in the CTIO for the Qlogic 2X00 fibre channel 79 * cards that 'auto-replenish' the f/w's ATIO count, but this is the basic 80 * gist of it. 81 * 82 * The third group that can show up in the response queue are Immediate 83 * Notification events. These include things like notifications of SCSI bus 84 * resets, or Bus Device Reset messages or other messages received. This 85 * a classic oddbins area. It can get a little weird because you then turn 86 * around and acknowledge the Immediate Notify by writing an entry onto the 87 * request queue and then the f/w turns around and gives you an acknowledgement 88 * to *your* acknowledgement on the response queue (the idea being to let 89 * the f/w tell you when the event is *really* over I guess). 90 * 91 */ 92 93 94 /* 95 * A new response queue entry has arrived.
