71  * The Qlogic driver gets an interrupt to look at response queue entries.
72  * Some of these are status completions for initiatior mode commands, but
73  * if target mode is enabled, we get a whole wad of response queue entries
74  * to be handled here.
75  *
76  * Basically the split into 3 main groups: Lun Enable/Modification responses,
77  * SCSI Command processing, and Immediate Notification events.
78  *
79  * You start by writing a request queue entry to enable target mode (and
80  * establish some resource limitations which you can modify later).
81  * The f/w responds with a LUN ENABLE or LUN MODIFY response with
82  * the status of this action. If the enable was successful, you can expect...
83  *
84  * Response queue entries with SCSI commands encapsulate show up in an ATIO
85  * (Accept Target IO) type- sometimes with enough info to stop the command at
86  * this level. Ultimately the driver has to feed back to the f/w's request
87  * queue a sequence of CTIOs (continue target I/O) that describe data to
88  * be moved and/or status to be sent) and finally finishing with sending
89  * to the f/w's response queue an ATIO which then completes the handshake
90  * with the f/w for that command. There's a lot of variations on this theme,
91  * including flags you can set in the CTIO for the Qlogic 2X00 fibre channel
92  * cards that 'auto-replenish' the f/w's ATIO count, but this is the basic
93  * gist of it.
94  *
95  * The third group that can show up in the response queue are Immediate
96  * Notification events. These include things like notifications of SCSI bus
97  * resets, or Bus Device Reset messages or other messages received. This
98  * a classic oddbins area. It can get  a little weird because you then turn
99  * around and acknowledge the Immediate Notify by writing an entry onto the
100  * request queue and then the f/w turns around and gives you an acknowledgement
101  * to *your* acknowledgement on the response queue (the idea being to let
102  * the f/w tell you when the event is *really* over I guess).
103  *

108  * A new response queue entry has arrived. The interrupt service code
109  * has already swizzled it into the platform dependent from canonical form.
110  *
111  * Because of the way this driver is designed, unfortunately most of the
112  * actual synchronization work has to be done in the platform specific
113  * code- we have no synchroniation primitives in the common code.
