/*
|
|
* FC Port Database entry.
|
|
*
|
|
* It has a handle that the f/w uses to address commands to a device.
|
|
* This handle's value may be assigned by the firmware (e.g., for local loop
|
|
* devices) or by the driver (e.g., for fabric devices).
|
|
*
|
|
* It has a state. If the state if VALID, that means that we've logged into
|
|
* the device. We also *may* have a initiator map index entry. This is a value
|
|
* from 0..MAX_FC_TARG that is used to index into the isp_ini_map array. If
|
|
* the value therein is non-zero, then that value minus one is used to index
|
|
* into the Port Database to find the handle for forming commands. There is
|
|
* back-index minus one value within to Port Database entry that tells us
|
|
* which entry in isp_ini_map points to us (to avoid searching).
|
|
*
|
|
* Local loop devices the firmware automatically performs PLOGI on for us
|
|
* (which is why that handle is imposed upon us). Fabric devices we assign
|
|
* a handle to and perform the PLOGI on.
|
|
*
|
|
* When a PORT DATABASE CHANGED asynchronous event occurs, we mark all VALID
|
|
* entries as PROBATIONAL. This allows us, if policy says to, just keep track
|
|
* of devices whose handles change but are otherwise the same device (and
|
|
* thus keep 'target' constant).
|
|
*
|
|
* In any case, we search all possible local loop handles. For each one that
|
|
* has a port database entity returned, we search for any PROBATIONAL entry
|
|
* that matches it and update as appropriate. Otherwise, as a new entry, we
|
|
* find room for it in the Port Database. We *try* and use the handle as the
|
|
* index to put it into the Database, but that's just an optimization. We mark
|
|
* the entry VALID and make sure that the target index is updated and correct.
|
|
*
|
|
* When we get done searching the local loop, we then search similarily for
|
|
* a list of devices we've gotten from the fabric name controller (if we're
|
|
* on a fabric). VALID marking is also done similarily.
|
|
*
|
|
* When all of this is done, we can march through the database and clean up
|
|
* any entry that is still PROBATIONAL (these represent devices which have
|
|
* departed). Then we're done and can resume normal operations.
|
|
*
|
|
* Negative invariants that we try and test for are:
|
|
*
|
|
* + There can never be two non-NIL entries with the same { Port, Node } WWN
|
|
* duples.
|
|
*
|
|
* + There can never be two non-NIL entries with the same handle.
|
|
*
|
|
* + There can never be two non-NIL entries which have the same ini_map_idx
|
|
* value.

|
|
* 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.
