If the enable was successful, you can expect... 82 * 83 * Response queue entries with SCSI commands encapsulate show up in an ATIO 84 * (Accept Target IO) type- sometimes with enough info to stop the command at 85 * this level. Ultimately the driver has to feed back to the f/w's request 86 * queue a sequence of CTIOs (continue target I/O) that describe data to 87 * be moved and/or status to be sent) and finally finishing with sending 88 * to the f/w's response queue an ATIO which then completes the handshake 89 * with the f/w for that command. There's a lot of variations on this theme, 90 * including flags you can set in the CTIO for the Qlogic 2X00 fibre channel 91 * cards that 'auto-replenish' the f/w's ATIO count, but this is the basic 92 * gist of it. 93 * 94 * The third group that can show up in the response queue are Immediate 95 * Notification events. These include things like notifications of SCSI bus 96 * resets, or Bus Device Reset messages or other messages received. This 97 * a classic oddbins area. It can get a little weird because you then turn 98 * around and acknowledge the Immediate Notify by writing an entry onto the 99 * request queue and then the f/w turns around and gives you an acknowledgement 100 * to *your* acknowledgement on the response queue (the idea being to let 101 * the f/w tell you when the event is *really* over I guess). 102 * 103 */ 104 105 106 /* 107 * A new response queue entry has arrived.
