We also revive loop down freezes. We also externaliz within isp isp_prt_endcmd so something outside the core module can print something about a command completing. Also some work in progress to assist in handling timed out commands better. Partially Sponsored by: Panasas Approved by: re (kib) MFC after: 1 month

|

* 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_dev_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_dev_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.
|

*

|
|
