266 * FC Port Database entry.
268 * It has a handle that the f/w uses to address commands to a device.
269 * This handle's value may be assigned by the firmware (e.g., for local loop
270 * devices) or by the driver (e.g., for fabric devices).
272 * It has a state. If the state if VALID, that means that we've logged into
273 * the device. We also *may* have a initiator map index entry. This is a value
274 * from 0..MAX_FC_TARG that is used to index into the isp_ini_map array. If
275 * the value therein is non-zero, then that value minus one is used to index
276 * into the Port Database to find the handle for forming commands. There is
277 * back-index minus one value within to Port Database entry that tells us
278 * which entry in isp_ini_map points to us (to avoid searching).
280 * Local loop devices the firmware automatically performs PLOGI on for us
281 * (which is why that handle is imposed upon us). Fabric devices we assign
282 * a handle to and perform the PLOGI on.
284 * When a PORT DATABASE CHANGED asynchronous event occurs, we mark all VALID
285 * entries as PROBATIONAL. This allows us, if policy says to, just keep track
286 * of devices whose handles change but are otherwise the same device (and
287 * thus keep 'target' constant).
289 * In any case, we search all possible local loop handles. For each one that
290 * has a port database entity returned, we search for any PROBATIONAL entry
291 * that matches it and update as appropriate. Otherwise, as a new entry, we
292 * find room for it in the Port Database. We *try* and use the handle as the
293 * index to put it into the Database, but that's just an optimization. We mark
294 * the entry VALID and make sure that the target index is updated and correct.
296 * When we get done searching the local loop, we then search similarily for
297 * a list of devices we've gotten from the fabric name controller (if we're
298 * on a fabric). VALID marking is also done similarily.
300 * When all of this is done, we can march through the database and clean up
301 * any entry that is still PROBATIONAL (these represent devices which have
302 * departed). Then we're done and can resume normal operations.
304 * Negative invariants that we try and test for are:
306 * + There can never be two non-NIL entries with the same { Port, Node } WWN
309 * + There can never be two non-NIL entries with the same handle.
311 * + There can never be two non-NIL entries which have the same ini_map_idx
316 * This is the handle that the firmware needs in order for us to
317 * send commands to the device. For pre-24XX cards, this would be
322 * The ini_map_idx, if nonzero, is the system virtual target ID (+1)
323 * as a cross-reference with the isp_ini_map.
325 * A device is 'autologin' if the firmware automatically logs into
326 * it (re-logins as needed). Basically, local private loop devices.
328 * The state is the current state of thsi entry.
330 * Role is Initiator, Target, Both
332 * Portid is obvious, as or node && port WWNs. The new_role and
333 * new_portid is for when we are pending a change.

757 * Platform Dependent to External to Internal Control Function
759 * Assumes locks are held on entry. You should note that with many of

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

810 * Platform Dependent to Internal to External Control Function
811 * (each platform must provide such a function)
813 * Assumes locks are held.
815 * A few notes about some of these functions:
817 * ISPASYNC_CHANGE_NOTIFY notifies the outer layer that a change has
818 * occurred that invalidates the list of fabric devices known and/or
819 * the list of known loop devices. The argument passed is a pointer
820 * whose values are defined below (local loop change, name server
821 * change, other). 'Other' may simply be a LIP, or a change in
822 * connection topology.
824 * ISPASYNC_FABRIC_DEV announces the next element in a list of
825 * fabric device names we're getting out of the name server. The
826 * argument points to a GET ALL NEXT response structure. The list
827 * is known to terminate with an entry that refers to ourselves.
828 * One of the main purposes of this function is to allow outer
829 * layers, which are OS dependent, to set policy as to which fabric
830 * devices might actually be logged into (and made visible) later
831 * at ISPCTL_PDB_SYNC time. Since there's a finite number of fabric
832 * devices that we can log into (256 less 3 'reserved' for F-port
833 * topologies), and fabrics can grow up to 8 million or so entries
834 * (24 bits of Port Address, less a wad of reserved spaces), clearly
835 * we had better let the OS determine login policy.
837 * ISPASYNC_PROMENADE has an argument that is a pointer to an integer which
838 * is an index into the portdb in the softc ('target'). Whether that entry's
839 * valid tag is set or not says whether something has arrived or departed.
840 * The name refers to a favorite pastime of many city dwellers- watching
841 * people come and go, talking of Michaelangelo, and so on..
843 * ISPASYNC_UNHANDLED_RESPONSE gives outer layers a chance to parse a
844 * response queue entry not otherwise handled. The outer layer should
845 * return non-zero if it handled it. The 'arg' points to an unmassaged
846 * response queue entry.
