99 * The Qlogic driver gets an interrupt to look at response queue entries.
100 * Some of these are status completions for initiatior mode commands, but
101 * if target mode is enabled, we get a whole wad of response queue entries
102 * to be handled here.
103 *
104 * Basically the split into 3 main groups: Lun Enable/Modification responses,
105 * SCSI Command processing, and Immediate Notification events.
106 *
107 * You start by writing a request queue entry to enable target mode (and
108 * establish some resource limitations which you can modify later).
109 * The f/w responds with a LUN ENABLE or LUN MODIFY response with
110 * the status of this action. If the enable was successful, you can expect...
111 *
112 * Response queue entries with SCSI commands encapsulate show up in an ATIO
113 * (Accept Target IO) type- sometimes with enough info to stop the command at
114 * this level. 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 *

135 /*
136 * A new response queue entry has arrived. The interrupt service code
137 * has already swizzled it into the platform dependent from canonical form.
138 *
139 * Because of the way this driver is designed, unfortunately most of the
140 * actual synchronization work has to be done in the platform specific
141 * code- we have no synchroniation primitives in the common code.
