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

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