ICBOPT_PORTNAME to ICBOPT_BOTH_WWNS as being more descriptive.
Change handles to 16 bits. Add ISPCTL_RUN_MBOXCMD control function.

isp_getmap helper function (for getting Loop Position map). Make
sure we (for our own benefit) mark req_state_flags with RQSF_GOT_SENSE
for Fibre Channel if we got sense data- the !*$)!*$)~*$)*$ Qlogic
f/w doesn't do so. Add ISPCTL_SCAN_FABRIC, ISPCTL_SCAN_LOOP, ISPCTL_SEND_LIP,
and ISPCTL_GET_POSMAP isp_control functions. Correctly send async notifications
upstream for changes in the name server, changes in the port database, and
f/w crashes. Correctly set topology when we get a ASYNC_PTPMODE event.
Quite massively redo how we handle Loop events- we've now added several
intermediate states between LOOP_PDB_RCVD and LOOP_READY. This allows us
a lot finer control about how we scan fabric, whether we go further
than scanning fabric, how we look at the local loop, and whether we
merge entries at the level or not. This is the next to last step for
moving managing loop state out of the core module entirely (whereupon
loop && fabric events will simply freeze the command queue and a thread
will run to figure out what's changed and *it* will re-enable the queu).
This fine amount of control also gets us closer to having an external
policy engine decide which fabric devices we really want to log into.
When resetting the Qlogic 2X00 units, reset the FPM (Fibre Protocol
Module) and FBM (Fibre Buffer Modules). Also remember to clear the
semaphore registers. Tell the RISC processor to not halt on FPM
parity errors.
Throw out the ISP_CFG_NOINIT silliness and instead go to the use of
adapter 'roles' to see whether one completes initialization or not
(mostly for Fibre Channel). The ultimate intent, btw, of all of this
is to have a warm standby adapter for failover reasons. Because
we do roles now, setting of Target Capable Class 3 service parameters
in the ICB for the 2x00 cards reflects from role. Also, in isp_start,
if we're not supporting an initiator role, we bounce outgoing commands
with a Selection Timeout error. Also clean out the TOGGLE_TMODE
goop for FC- there is no toggling of target mode like there is
for parallel SCSI cards.
Do more cleanup with respect to using target ids 0..125 in F-port
topologies. Also keep track of things which *were* fabric devices
so that when you rescan the fabric you can notify the outer layers
when fabric devices go away.
Only force a LOGOUT for fabric devices if they're still logged in
(i.e., you cat their Port Database entry. Clean up the Get All Next
scanning.
Finally, use a new tag in the softc to store the opcode for the
last mailbox command used so we can report which opcode timed
out.

wwn handling. Do a Register FC4 Type (so that we can work with McData
switches). Allow F-port topologies to use the target range 0..125 for
logging in fabric devices. We changed ISPASYNC_PDB_CHANGED to
ISPASYNC_LOGGED_INOUT and now use ISPASYNC_CHANGE_NOTIFY for both
loop && fabric events.

instrumentation for interrupts, specific topology preferences for
the 2200. Fix the hole in the OpenBSD port becuause there'd been
no maxluns limit from the midlayer and have the command routine
bounce commands > the maxluns for a particular controller (in
particular, Qlogic FC cards where we can't tell when it hasn't been
us that have loaded the F/W whether or not SCCLUN is in effect
or not).

Major rewrite of a lot of internals- far too many to list. Cleaner
locking, more paramaterization, an isp_prt logging function that
handles debugging as well as error printouts. We also should no
longer hang if there is no Loop for Fibre Channel when booting.
The file ispvar.h now contains a list of all platform required macros
and explanation as to what they're for. This should make maintenance
easier.
|
|
routines are not necessarily polled now- this should cut down on some of
the spurious lost commands that have occurred. Also, we now watchdog each
command and make sure that command constipation doesn't occur (which it
has been documented to do on the QLA2100 cards).
|
|
against targets < 129 if we're on a Public Loop- we can have those, yes.
Fix all the settings isp_sendmarker all throughout this file to OR in
the bus that we are trying to synchronize (e.g., after a bus reset)- this
way we don't wipe out pending sendmarker settings that haven't been done
yet.
|
|
wipe out the whole marker flag when a bus event happens on one channel- just
or in the channel that needs to have a marker sent. Correctly mark a
PORT CHANGED error with a 'selection timeout'.
|
|
Do some SNS fabric suppor tchanges. Roll revision levels. Tested on
GENERIC i386 && sparc.
|
|
so that a SCSIDEBUG kernel doesn't completely overrun the
console.
|
|
against f/w revision because we'll now use initiator only mode f/w
(if loading f/w) because we get more commands active in this case (and
avoid some apparent sloppiness wrt Qlogic's f/w release practices).

FABRIC support...
|
|
settings you've just sent them and return random values if you follow
the set by a get. This causes problems when you latter run a Tag-enabled
command when you've command tagged mode off.
