69 * The Qlogic driver gets an interrupt to look at response queue entries.
70 * Some of these are status completions for initiatior mode commands, but
71 * if target mode is enabled, we get a whole wad of response queue entries
74 * Basically the split into 3 main groups: Lun Enable/Modification responses,
75 * SCSI Command processing, and Immediate Notification events.
77 * You start by writing a request queue entry to enable target mode (and
78 * establish some resource limitations which you can modify later).
79 * The f/w responds with a LUN ENABLE or LUN MODIFY response with
80 * the status of this action. If the enable was successful, you can expect...
82 * Response queue entries with SCSI commands encapsulate show up in an ATIO
83 * (Accept Target IO) type- sometimes with enough info to stop the command at
84 * this level. Ultimately the driver has to feed back to the f/w's request
85 * queue a sequence of CTIOs (continue target I/O) that describe data to
86 * be moved and/or status to be sent) and finally finishing with sending
87 * to the f/w's response queue an ATIO which then completes the handshake
88 * with the f/w for that command. There's a lot of variations on this theme,
89 * including flags you can set in the CTIO for the Qlogic 2X00 fibre channel
90 * cards that 'auto-replenish' the f/w's ATIO count, but this is the basic
93 * The third group that can show up in the response queue are Immediate
94 * Notification events. These include things like notifications of SCSI bus
95 * resets, or Bus Device Reset messages or other messages received. This
96 * a classic oddbins area. It can get a little weird because you then turn
97 * around and acknowledge the Immediate Notify by writing an entry onto the
98 * request queue and then the f/w turns around and gives you an acknowledgement
99 * to *your* acknowledgement on the response queue (the idea being to let
100 * the f/w tell you when the event is *really* over I guess).
106 * A new response queue entry has arrived. The interrupt service code
107 * has already swizzled it into the platform dependent from canonical form.
109 * Because of the way this driver is designed, unfortunately most of the
110 * actual synchronization work has to be done in the platform specific
111 * code- we have no synchroniation primitives in the common code.
