*
|
|
* ISPCTL_FCLINK_TEST tests to make sure we have good fibre channel link.
|
|
* The argument is a pointer to an integer which is the time, in microseconds,
|
|
* we should wait to see whether we have good link. This test, if successful,
|
|
* lets us know our connection topology and our Loop ID/AL_PA and so on.
|
|
* You can't get anywhere without this.
|
|
*
|
|
* ISPCTL_SCAN_FABRIC queries the name server (if we're on a fabric) for
|
|
* all entities using the FC Generic Services subcommand GET ALL NEXT.
|
|
* For each found entity, an ISPASYNC_FABRICDEV event is generated (see
|
|
* below).
|
|
*
|
|
* ISPCTL_SCAN_LOOP does a local loop scan. This is only done if the connection
|
|
* topology is NL or FL port (private or public loop). Since the Qlogic f/w
|
|
* 'automatically' manages local loop connections, this function essentially
|
|
* notes the arrival, departure, and possible shuffling around of local loop
|
|
* entities. Thus for each arrival and departure this generates an isp_async
|
|
* event of ISPASYNC_PROMENADE (see below).
|
|
*
|
|
* ISPCTL_PDB_SYNC is somewhat misnamed. It actually is the final step, in
|
|
* order, of ISPCTL_FCLINK_TEST, ISPCTL_SCAN_FABRIC, and ISPCTL_SCAN_LOOP.
|
|
* The main purpose of ISPCTL_PDB_SYNC is to complete management of logging
|
|
* and logging out of fabric devices (if one is on a fabric) and then marking
|
|
* the 'loop state' as being ready to now be used for sending commands to
|
|
* devices. Originally fabric name server and local loop scanning were
|
|
* part of this function. It's now been separated to allow for finer control.

* occurred that invalidates the list of fabric devices known and/or
|
|
* the list of known loop devices. The argument passed is a pointer
|
|
* whose values are defined below (local loop change, name server
|
|
* change, other). 'Other' may simply be a LIP, or a change in
|
|
* connection topology.
|
|
*
|
|
* ISPASYNC_FABRIC_DEV announces the next element in a list of
|
|
* fabric device names we're getting out of the name server. The
|
|
* argument points to a GET ALL NEXT response structure. The list
|
|
* is known to terminate with an entry that refers to ourselves.
|
|
* One of the main purposes of this function is to allow outer
|
|
* layers, which are OS dependent, to set policy as to which fabric
|
|
* devices might actually be logged into (and made visible) later
|
|
* at ISPCTL_PDB_SYNC time. Since there's a finite number of fabric
|
|
* devices that we can log into (256 less 3 'reserved' for F-port
|
|
* topologies), and fabrics can grow up to 8 million or so entries
|
|
* (24 bits of Port Address, less a wad of reserved spaces), clearly
|
|
* we had better let the OS determine login policy.
|
|
*
|
|
* ISPASYNC_PROMENADE has an argument that is a pointer to an integer which
|
|
* is an index into the portdb in the softc ('target'). Whether that entry's
|
|
* valid tag is set or not says whether something has arrived or departed.
|
|
* The name refers to a favorite pastime of many city dwellers- watching
|
|
* people come and go, talking of Michaelangelo, and so on..
|
|
*
|
|
* ISPASYNC_UNHANDLED_RESPONSE gives outer layers a chance to parse a
|
|
* response queue entry not otherwise handled. The outer layer should
|
|
* return non-zero if it handled it. The 'arg' points to an unmassaged
|

* response queue entry.

|
|
* XS_TAG_TYPE(xs) which type of tag to use
|
|
* XS_SETERR(xs) set error state
|
|
*
|
|
* HBA_NOERROR command has no erros
|
|
* HBA_BOTCH hba botched something
|
|
* HBA_CMDTIMEOUT command timed out
|
|
* HBA_SELTIMEOUT selection timed out (also port logouts for FC)
|
|

|
|
* HBA_ABORTED command was aborted (by request)
|
|
* HBA_DATAOVR a data overrun was detected
|
|
* HBA_ARQFAIL Automatic Request Sense failed
|
|
*
|
|
* XS_ERR(xs) return current error state
|
|
* XS_NOERR(xs) there is no error currently set
|
|
* XS_INITERR(xs) initialize error state
|
|
*
|
|
* XS_SAVE_SENSE(xs, sp) save sense data
|
|
*
|
|
* XS_SET_STATE_STAT(isp, sp, xs) platform dependent interpreter of
|
|
* response queue entry status bits
|
|
*
|
|
*
|
|
* DEFAULT_IID(struct ispsoftc *) Default SCSI initiator ID
|
|
* DEFAULT_LOOPID(struct ispsoftc *) Default FC Loop ID
|
|
* DEFAULT_NODEWWN(struct ispsoftc *) Default Node WWN
|
|
* DEFAULT_PORTWWN(struct ispsoftc *) Default Port WWN
|
|
* DEFAULT_FRAMESIZE(struct ispsoftc *) Default Frame Size
|
|
* DEFAULT_EXEC_THROTTLE(struct ispsoftc *) Default Execution Throttle
|
|
* These establish reasonable defaults for each platform.
|
|
* These must be available independent of card NVRAM and are
|
|
* to be used should NVRAM not be readable.
|
|
*
|
|
* ISP_NODEWWN(struct ispsoftc *) FC Node WWN to use
|
|
* ISP_PORTWWN(struct ispsoftc *) FC Port WWN to use
|
|
*
|
|
* These are to be used after NVRAM is read. The tags
|
|
* in fcparam.isp_{node,port}wwn reflect the values
|
|
* read from NVRAM (possibly corrected for card botches).
|
|
* Each platform can take that information and override
|
|
* it or ignore and return the Node and Port WWNs to be
|
|
* used when sending the Qlogic f/w the Initialization Control
|
|
* Block.
