Ultimately the driver has to feed back to the f/w's request 115 * queue a sequence of CTIOs (continue target I/O) that describe data to 116 * be moved and/or status to be sent) and finally finishing with sending 117 * to the f/w's response queue an ATIO which then completes the handshake 118 * with the f/w for that command. There's a lot of variations on this theme, 119 * including flags you can set in the CTIO for the Qlogic 2X00 fibre channel 120 * cards that 'auto-replenish' the f/w's ATIO count, but this is the basic 121 * gist of it. 122 * 123 * The third group that can show up in the response queue are Immediate 124 * Notification events. These include things like notifications of SCSI bus 125 * resets, or Bus Device Reset messages or other messages received. This 126 * a classic oddbins area. It can get a little weird because you then turn 127 * around and acknowledge the Immediate Notify by writing an entry onto the 128 * request queue and then the f/w turns around and gives you an acknowledgement 129 * to *your* acknowledgement on the response queue (the idea being to let 130 * the f/w tell you when the event is *really* over I guess). 131 * 132 */ 133 134 135 /* 136 * A new response queue entry has arrived.
