cb8461c836 (semiforced commit to add comment missed in last delta)
Add a maximum response length for FCP RSPNS IUs.

Clarify some of the FC option words for setting parameters
and try and disable automatic PRLI when in target mode- this
should correct some cases of N-port topologies with 23XX cards
where we put out an illegal PRLI (in target mode only we're
not supposed to put out a PRLI).

2df76c160b Add 8Gb support (isp_2500). Fix a fair number of configuration and
firmware loading bugs.

Target mode support has received some serious attention to make it
more usable and stable.

Some backward compatible additions to CAM have been made that make
target mode async events easier to deal with have also been put
into place.

Further refinement and better support for NP-IV (N-port Virtualization)
is now in place.

Code for release prior to RELENG_7 has been stripped away for code clarity.

af4394d40a Don't attempt to load illegal hard loop addresses into
an ICB. This shows up on card restarts, and usually for
2200-2300 cards. What happens is that we start up,
attempting to acquire a hard address. We end up instead
being an F-port topology, which reports out a loop id
of 0xff (or 0xffff for 2K Login f/w). Then, if we restart,
we end up telling the card to go off an acquire this loop
address, which the card then rejects. Bah.

Compilation fixes from Solaris port.

8a97c03a7a Do various fixes to support firmware loading for the 2322
(and by extension, the 2422).

One peculiar thing I've found with the 2322 is that if you
don't force it to do Hard LoopID acquisition, the firmware
crashes. This took a while to figure out.

While we're at it, fix various bugs having to do with NVRAM
reading and option setting with respect to pieces of NVRAM.

1dae40eb49 a) clean up some declaration stuff (i.e., make more modern with respect
to getting rid u_int for uint and so on).

b) Turn back on 64 bit DAC support. Cheeze it a bit in that we have two
DMA callback functions- one when we have bus_addr_t > 4 bits in width and
the other which should be normal. Even Cheezier in that we turn off setting
up DMA maps to be BUS_SPACE_MAXADDR if we're in ISP_TARGET_MODE. More work
on this in a week or so.

c) Tested under amd64 and 1MB DFLTPHYS, sparc64, i386 (PAE, but insufficient
memory to really test > 4GB). LINT check under amd64.

e526523707 First of several commits as this driver is dusted off and maybe brought
up to date.  Principle changes for this reelase is to support 2K Port Login
firmware. This allows us to support the 2322 (and 2422 4Gb) cards which only
come with the 2K Port Login firmware. The 2322 should now work- but we don't
have firmware sets for it in ispfw (as the change to load 2K Port Login f/w
hasn't been made- that f/w is so big it has to be loaded in more than one
chunk).

Other changes are the beginnings of cleaning up some long standing target
mode issues. The next changes here will incorporate a lot of bug fixes
from others.

Finally, some copyright cleanup and attempts to make the parts of the
driver that are FreeBSD specific start conforming more to FreeBSD style.

4a999c65de Scale back # of luns supported for SCC to 16384- oops- top 3 bits are a
lun address modifier of sorts. Only an HP XP-512 seems to have cared.

Fix a few misplaced pointers for the new fabric goop, which has been
demonstrated to work on newer Brocades and McData switches now.
Put in commented out code which would run GFF_ID if the QLogic f/w
allowed it.

Don't whine about not being able to find a handle for a command if it
was a command aborted (by us).

029f13c671 Fix bus dma segment count to be based off of MAXPHYS, not BUS_SPACE_MAXSIZE.
Grumble. I've seen better documented architectures out of Redmond.

Redo fabric evaluation to not use GET ALL NEXT (GA_NXT). Switches seem
to be trying to wriggle out of supporting this well. Instead, use
GID_FT to get a list of Port IDs and then use GPN_ID/GNN_ID to find the
port and node wwn. This should make working on fabrics a bit cleaner and
more stable.

This also caused some cleanup of SNS subcommand canonicalization so that
we can actually check for FS_ACC and FS_RJT, and if we get an FS_RJT,
print out the reason and explanation codes.

We'll keep the old GA_NXT method around if people want to uncomment a
controlling definition in ispvar.h.

This also had us clean up ISPASYNC_FABRICDEV to use a local lportdb argument
and to have the caller explicitly say that a device is at the end of the
fabric list.

b894188248 Support for f/w crash dumps (2200 && 23XX).
If you want QLogic to look at a potential f/w problem for FC cards, you really
have to provide them info in the format they expect. This involves dumping
a lot of hardware registers (> 300 16 bit registers) and a lot of SRAM
(> 128KB minimum). Thus all of this code is #ifdef protected which will
become an option so that the memory allocation of where to dump the crash
image is pretty expensive. It's worth it if you have a reproducible problem
because they have some tools that can tell them, given the f/w version,
the precise state of everything.

75c1e828c0 + A variety of 23XX changes:
disable MWI on 2300

	based on function code, set an 'isp_port' for the 2312- it's a
	separate instance, but the NVRAM is shared, and the second port's
	NVRAM is at offset 256.

+ Enable RIO operation for LVD SCSI cards. This makes a *big* difference
as even under reasonable load we get batched completions of about 30
commands at a time on, say, an ISP1080.

+ Do 'continuation' mailbox commands- this allows us to specify a work
area within the softc and 'continue' repeated mailbox commands. This is
more or less on an ad hoc basis and is currently only used for firmware
loading (which f/w now loads substantially faster becuase the calling
thread is only woken when all the f/w words are loaded- not for each
one of the 40000 f/w words that gets loaded).

+ If we're about to return from isp_intr with a 'bogus interrupt' indication,
and we're not a 23XX card, check to see whether the semaphore register is
currently *2* (not *1* as it should be) and whether there's an async completion
sitting in outgoing mailbox0. This seems to capture cases of lost fast posting
and RIO interrupts that the 12160 && 1080 have been known to pump out under
extreme load (extreme, as in > 250 active commands).

+ FC_SCRATCH_ACQUIRE/FC_SCRATCH_RELEASE macros.

+ Endian correct swizzle/unswizzle of an ATIO2 that has a WWPN in it.

2903b27203 Implement REDUCED INTERRUPT OPERATION usage form FC cards- this allows the
firmware to delay completion of commands so that it can attempt to batch
a bunch of completions at once- either returning 16 bit handles in mailbox
registers, or in a resposne queue entry that has a whole wad of 16 bit handles.

Distinguish between 2300 and 2312 chipsets- if only because the revisions
on the chips have different meanings.

Add more instrumentation plus ISP_GET_STATS and ISP_CLR_STATS ioctls.
Run up the maximum number of response queue entities we'll look at
per interrupt.

If we haven't set HBA role yet, always return success from isp_fc_runstate.

4fd13c1ba2 Major restructuring for swizzling to the request queue and unswizzling from
the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have
a complete set of inline functions in isp_inline.h. Each platform is
responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32}
macros.

The reason this needs to be done is that we need to have a single set of
functions that will work correctly on multiple architectures for both little
and big endian machines. It also needs to work correctly in the case that
we have the request or response queues in memory that has to be treated
specially (e.g., have ddi_dma_sync called on it for Solaris after we update
it or before we read from it). It also has to handle the SBus cards (for
platforms that have them) which, while on a Big Endian machine, do *not*
require *most* of the request/response queue entry fields to be swizzled
or unswizzled.

One thing that falls out of this is that we no longer build requests in the
request queue itself. Instead, we build the request locally (e.g., on the
stack) and then as part of the swizzling operation, copy it to the request
queue entry we've allocated. I thought long and hard about whether this was
too expensive a change to make as it in a lot of cases requires an extra
copy. On balance, the flexbility is worth it. With any luck, the entry that
we build locally stays in a processor writeback cache (after all, it's only
64 bytes) so that the cost of actually flushing it to the memory area that is
the shared queue with the PCI device is not all that expensive. We may examine
this again and try to get clever in the future to try and avoid copies.

Another change that falls out of this is that MEMORYBARRIER should be taken
a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the
entry being added. But there had been many other places this had been missing.
It's now very important that it be done.

Additional changes:

Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry,
the iptr value that gets returned is the value we intend to eventually plug
into the ISP registers as the entry *one past* the last one we've written-
*not* the current entry we're updating. All along we've been calling sync
functions on the wrong index value. Argh. The 'fix' here is to rename all
'iptr' variables as 'nxti' to remember that this is the 'next' pointer-
not the current pointer.

Devote a single bit to mboxbsy- and set aside bits for output mbox registers
that we need to pick up- we can have at least one command which does not
have any defined output registers (MBOX_EXECUTE_FIRMWARE).

4102f2f6ef Fix a longstanding bug- we had the sense of what bit 14
for the ICB firmware options meant- *I* had taken it to
mean that if you set it, Node Name would be ignored and
derived from Port Name. Actually, it meant the opposite.
As a consequence- change ICBOPT_USE_PORTNAME to the
define ICBOPT_BOTH_WWNS- makes more sense.

Fix wrong input bitmap for MBOX_DUMP_RAM command. Call
ISP_DUMPREGS if we get a f/w crash. Add ISPCTL_RUN_MBOXCMD
control command (so outer layers can run a mailbox command
directly) and add a ISPASYNC_UNHANDLED_RESPONSE hook so
outer layers can understand response queue entries we
might not know about.
