293 * FC Port Database entry.
295 * It has a handle that the f/w uses to address commands to a device.
296 * This handle's value may be assigned by the firmware (e.g., for local loop
297 * devices) or by the driver (e.g., for fabric devices).
299 * It has a state. If the state if VALID, that means that we've logged into
300 * the device. We also *may* have a initiator map index entry. This is a value
301 * from 0..MAX_FC_TARG that is used to index into the isp_dev_map array. If
302 * the value therein is non-zero, then that value minus one is used to index
303 * into the Port Database to find the handle for forming commands. There is
304 * back-index minus one value within to Port Database entry that tells us
305 * which entry in isp_dev_map points to us (to avoid searching).
307 * Local loop devices the firmware automatically performs PLOGI on for us
308 * (which is why that handle is imposed upon us). Fabric devices we assign
309 * a handle to and perform the PLOGI on.
311 * When a PORT DATABASE CHANGED asynchronous event occurs, we mark all VALID
312 * entries as PROBATIONAL. This allows us, if policy says to, just keep track
313 * of devices whose handles change but are otherwise the same device (and
314 * thus keep 'target' constant).
316 * In any case, we search all possible local loop handles. For each one that
317 * has a port database entity returned, we search for any PROBATIONAL entry
318 * that matches it and update as appropriate. Otherwise, as a new entry, we
319 * find room for it in the Port Database. We *try* and use the handle as the
320 * index to put it into the Database, but that's just an optimization. We mark
321 * the entry VALID and make sure that the target index is updated and correct.
323 * When we get done searching the local loop, we then search similarily for
324 * a list of devices we've gotten from the fabric name controller (if we're
325 * on a fabric). VALID marking is also done similarily.
327 * When all of this is done, we can march through the database and clean up
328 * any entry that is still PROBATIONAL (these represent devices which have
329 * departed). Then we're done and can resume normal operations.
331 * Negative invariants that we try and test for are:
333 * + There can never be two non-NIL entries with the same { Port, Node } WWN
336 * + There can never be two non-NIL entries with the same handle.
338 * + There can never be two non-NIL entries which have the same dev_map_idx
343 * This is the handle that the firmware needs in order for us to
344 * send commands to the device. For pre-24XX cards, this would be
350 * The dev_map_idx, if nonzero, is the system virtual target ID (+1)
351 * as a cross-reference with the isp_dev_map.
353 * A device is 'autologin' if the firmware automatically logs into
354 * it (re-logins as needed). Basically, local private loop devices.
356 * The state is the current state of this entry.
358 * Role is Initiator, Target, Both
360 * Portid is obvious, as are node && port WWNs. The new_role and
361 * new_portid is for when we are pending a change.
363 * The 'target_mode' tag means that this entry arrived via a
364 * target mode command and is immune from normal flushing rules.
365 * You should also never see anything with an initiator role
