Sync with HEAD

Update isp driver to be in sync with other platforms. Mostly very minor changes
with effectively zero impact on NetBSD.

Sync with HEAD.

Synchronize with other platforms:

	Strongly architect handles so we can more easily detect bogus
	handles. This switches us to a full 32 bits for all handles.

	Handle the case of FC disks disappearing and then reappearing-
	at least at the FC transport level.

	Some better and finer control of debug and non-debug printouts.

Checkpoint of some fairly major isp(4) rototilling.

Reintroduce more of a 'channel' concept in preparation for NP-IV support.
This gets rid of the chanA/chanB concept as the 2400 can have up to 128
virtual channels. Actually, with MID firmware you can also have the 2200
and 2300 support 'channels, but they do it with an FL-Port topology.
Because FC cards can now have 'channels', just about every support
function for fibre channel had to be redone to have a channel index
as well.  Rototill isp_ioctl.h for channel stuff as well.

Pick up a lot of work about fabric management (hopefully better) and keep
work in place that will allow for dynamic attachment/detachment of devices
(if I can figure out how to make the midlayer support it).

Merge the target code with external trees. Eventually it might even
be sorted out on NetBSD.

Update some firmware stuff.

Do a number of 24XX related fixes: fix the actual getting of initiator
status correctly (which we never were doing before). Add an underrun
checker for 24XX. The process of sorting this out led to a whole bunch
of endian surprises that had to be dealt with. Fix NVRAM endian issues
for the 24XX as well.

Do a little 2200 related cleanup- in particular, turn off complaints about
not finding a fast posting handle when running with RIO enabled- we are
somehow getting duplicate completions in this case. If we ignore them and
don't complain, all is well, and we actually start averaging > 2 commands
completed per interrupt.

Sync with head.

Major update to isp(4) driver to bring it in line with external sources.

The major changes are:

 + 4Gb (24XX) card support
 + Rewritten fabric and loop evaluation code
 + New f/w sets

The 4Gb changes required major rototilling, which caused a rewrite of
fabric and loop eval code. The latter can now be set up to tune for
dynamic device arrival/departure if the framework is set up for it,
or to be firm about waiting for devices.

Testing has been principally on amd64, i386 and sparc64 and seems to
not have broken things for me.

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

netbsd.org -> NetBSD.org

This was the last commit of this kind to src/sys, which is now totally
"NetBSD.org clean".  Thanks for the patiance, and sorry for all the commits.

DMA, not dma nor Dma.

Catch up to -current

Remove ISP_DMA_ADDR_T as a 'type'. Instead, go off of whether
ISP_DAC_SUPPORTED is defined and do a real typedef for the size
of DMA addresses. ISP_DAC_SUPPORTED also decides how much of any
particular DMA address is significant.

Lose STRNCAT over the side.

Add in (sight unseen) 10160 support.

Fix a random 23XX ISR reading bug. Be chattier about HBA_BOTCH

Roll version minor.

Add DEFAULT_FRAMESIZE/DEFAULT_EXEC_THROTTLE/ISPASYNC_FW_RESTARTED
defines.

Catch up to -current.

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.

Catch up to -current.
(CVS: It's not just a program. It's an adventure!)

Handle Port Unavailable the same as Port Logout (i.e., send a LIP).

Unconst pointer to f/w in the ispdv structure. Too many compilers get
unhappy over our walking the array. Make casts as appropriate so that
initialization in structure is still happy.

Limit length of fabric to 256. This will all go away soon.

Do a cleaner case of keeping multiple CPUs/threads from reading the
same response queue entries.

Catch up with -current.

Catch up to -current.

Implement F/W crashdumps for 2200 && 2300 cards (kernel compile option).

Distinguish between 2312 and 2300 cards (they *are* different). Enable
RIO (Reduced Interrupt Operation) for the LVD cards (hey- I've seen
batched completions of the 30 commands at a time with this,....)...

If we get a Port Logout on local loop topologies, we have to force the
f/w to log back in. The easiest way (for us) to do this is to force
a LIP. This also will wake up the disk that probably just had a f/w crash.

Implement mailbox 'continuations'- this allows interrupts to re-drive
a mailbox command if it's one that just essentially repeats the previous
mailbox command (e.g., f/w download). This saves a boatload of sleep/wakeup
twitches.

If we're not a 2300 and we're about to return with a 'bogus interrupt'- check
the semaphore register to be non-zero at all and outgoing mailbox 0- this
seems to be where some of the lost ISP1080 commands came from.

More catchup.

Sync kqueue branch with -current.

Catch up to -current.

Implement REDUCED INTERRUPT OPERATION usage for 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.

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).

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.

For NetBSD, it does a ddi_dmamap_sync as appropriate. This gets us out of
the explicit ddi_dmamap_sync on the whole response queue that we did for SBus
cards at each interrupt.

Set things up so that platforms that cannot have an SBus don't get a lot of
the SBus code checks (dead coded out).

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).

Explicitly decode GetAllNext SNS Response back *as* a GetAllNext response.
Otherwise, we won't unswizzle it correctly.

Nuke some additional __P macros.

Catch up to -current.

Catch up with -current. Fix some bogons in the sparc64 kbd/ms
attach code. cd18xx conversion provided by mrg.

Fix various 2300 GB issues related to chip errata and documentation
misunderstandings. We also now can report our connection rate.

Catch up to -current.

Update the kqueue branch to HEAD.

Synchronize with FreeBSD/Linux.

Add support for 2 Gigabit cards (2300/2312). This necessitated a change
in how interrupts are down- the 23XX has not only a different place to check
for an interrupt, but unlike all other QLogic cards, you have to read the
status as a 32 bit word- not 16 bit words. Rather than have device specific
functions as called from the core module (in isp_intr), it makes more sense
to have the platform/bus modules do the gruntwork of splitting out the
isr, semaphore register and the first outgoing mailbox register (if needed)
*prior* to calling isp_intr (if calling isp_intr is necessary at all).

Add ISPCTL_RUN_MBOXCMD control op and ISPASYNC_UNHANDLED_RESPONSE async event.

Eliminate ISP2100_FABRIC- we always allow for fabric now. Add an
isp_iid_set/isp_iid for fibre channel- this is because we now
fake a port database entry for ourselves. Add the additional loop
states between LOOP_PDB_RCVD and LOOP_READY.

Change and comment on a wad of Fibre Channel isp_control functions.
Change and comment on some of the ISPASYNC Fibre Channel events.

Add was_fabric_dev/fabric_dev tags to our local FC database structure
(so we can see rapidly whether something was a fabric device but is
now gone).

Add a tag which says what role this adapter should take. It can take
on the value of None, Target, Initiator or Both. None is useful for
warm failover purposes. Remove the ISP_CFG_NOINIT silliness since
a role of "None" does this.

Add a isp_lastmbxcmd tag to store the opcode for the last mailbox
command used.

Pull up revisions 1.36-1.38 (requested by mjacob):
  Add in correct SBus bursting; upgrade to 2.01.26 firmware; pull to latest
  initiator mode level; make changes to WWN default handling; quiet
  chatty boot messages; fix endian code so MacPPC works; fix bug in
  lock recursion counter; fix bug which excluded all but NL-ports from
  being logged into on a fabric.

Sync with head (for UBC+NFS fixes, mostly).

ISPASYNC_PDB_CHANGED -> ISPASYNC_LOGGED_INOUT.

Sync with HEAD

Apply nearly all of Bill Sommerfeld's -Wformat patches. The one
change I didn't take is the %llu format- I can't have a common
across multiple platform module assume a %ll argument capability-
which really pointed out that I shouldn't be trying to *print*
something which could long long.

add an ISP_CFG_NOINIT flag

Fix pathnames in comment.

Sync with HEAD (for UBC fixes).

Finally fix this driver to be sensible about the ENDIAN dance. It's not
quite simply a question of the Qlogic being little endian and having
to have stuff swapped on big endian machines- it also has to do with the
fact that the SBus and PCI DMA layouts are wierd with respect to this.

At any rate, now finally fixed- works on Mac G4, tested it on a SS10
for sparc, checked on alpha to see if I've broken anything, and as
soon as I get another spare afternoon I'll finally install a sparc64
version which should just work (as it'll be like the Mac).

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

Change some of the WWN macros- eliminate PORT_FROM_NODE_WWN and make
sure we have a DEFAULT_{PORT,NODE}WWN and ISP_{NODE,PORT}WWN macro
as a requirement for all platforms.

Complete rewrite of internals for isp core version 2.0.
Pullup to netbsd-1-5 approved by thorpej@netbsd.org.

Add a maintenance note. Fix QFREE and QAVAIL macros to match change in usage.

Remove ispcmd_slow routine- SCBUSACCEL routine will set/clear tag/wide/sync.
Make some changes about where some things sit in the softc.

Core version 2.0 (platform version 1.0) rewrite of ISP driver. Some
interace cleanups, some new common functions. The major impact that
will be noticeable right away is that if you boot with not Fibre connected
to the FC cards, you no longer hang indefinitely.

Roll core version. Get rid of dogactive (no longer used). Add in some
volatile flags (isp_mboxbsy- keeps a bitmask of expected output mailbox
registers) and storage for them (isp_mboxtmp). Get rid of macroized
LUN widths. This is determined at run time.

Apply patch (requested by Matthew Jacob via he):
  Correctly account for F-port vs. F-port (no FLOGI_ACC) topologies.
  Make sure we get a port database entry for the fabric name server.
  Preserve fabric logins if the device didn't change across fabric
  or port database changes, or the device has already logged into
  us (e.g., for target/initiator dual role devices like Veritas
  SANbox). Propagate class 3 service parameter changes where devices
  can change roles.

  Fix all occurrences of setting a sendmarker so that setting it
  for one bus on dual bus cards doesn't wipe a pending sendmarker
  for other busses on the same card.

  Comments added and clarifications made in some of the target mode code.

  Add support for > 12 byte CDBs.  Split out nvram reading into
  per-card functions.  Add proper Ultra2/Ultra3 support.  Upgrade
  firmware.

add in 12160 (Ultra3) related definitions

Pull up revisions 1.21-1.28 (requested by mjacob):
  Untangle Qlogic firmware copyright problems and update firmware.
  Untangle some MD support issues for said firmware. Add 1280 (Dual
  LVD), 1240 (Dual Ultra), 2200 (2nd Generation Qlogic FC chipset).
  Fix some synchronous negotiation problems for parallel SCSI.
  Firm up some Fabric Support issues.

roll revision level and add some taret mode changes

Pull up to last week's -current.

Dual LVD (1280) support.

Roll core version minor. Clean out some target mode stuff. Respecify some
queue related functions to take u_int16_t's. Restructure the softc a bit.

mostly stylistic

Roll minor version. Change how f/w revisions are stored. Add some
defines to get max luns for a card. Make sure the RESULT_QUEUE_LEN is not less
than 64- I've seen breakage with that. Move the temp port database stuff
into the softc (ick). Remove most of the target mode stuff. Make xflist
storage an external outer layer thing (since it will now be allocated based
upon the maximum commands that this HBA can support rather than request
queue size).

Update from trunk.

Change to approved NASA/Ames copyright. Add Fabric support. Fix SCCLUN support.
Add code that tries to track LoopID shifting.

Sync w/ -current.

Do a fairly large internal restructuring to accomodate dual-bus host adapters
(e.g., the 1240). Include the new 1080/1240 NVRAM layout reading code. Some
moderately significant mailbox changes were necessary also to accomodate a
second channel.

Change f/w revision to major,minor,micro version. Add in ISP1040C definition.

add isp1080 support and some basic PDB change stuff

Update the driver with some infrastructure for the 1080. Fix an embarrassing
clock botch bug. Additional infrastructure for PDB change stuff.

Roll internal release tag. Roll core version minor. Fix broken DPARM_DEFAULT
define. Add a new config flag param (ISP_CFG_NONVRAM) whose intent it is
to cause NVRAM to be ignored. Add ISPASYNC_LOOP_DOWN and ISPASYNC_LOOP_UP
isp_async enums.

Implement and use Fast Posting for both parallel && fibre. Redo a bit of
the startup code. Implement a call to outer framework function so that
asynchronous events can be handled (e.g., speed negotiation, target mode).

Roll internal release tags.

bump isp_fifo_threshold tag top 3 bits

clean up headers; move uninit/watch to outer layers

Update BA for new max_lun parameter for SCSIbusses. Clearify maximum luns
for FC HB based upon a SCCLUN define (15 for normal- 255 out of a possible
65535 for SCCLUN). Propagate loopid as adapter_target.

Roll minor platform version. Roll core version number.

Update mailbox definitions with cleaner target mode structure definitions.
Clean up some ENDIAN stuff. Correct botched ISP2100_NVRAM_HARDLOOPID offset.

pull up revs 1.8-1.13 from trunk (mjacob)

cleanup header to be just NetBSD, roll rev, change QDEPTH to QAVAIL macro

turn into a debug message an ABOUT F/W failure. Add ISPCTL_UPDATE_PARAMS isp_control case

Roll major revision. Change some definitions around. Add more current device
state stuff. Make DPARM flags full 16 bits (no shifting needed) and add
the 2 new ones for the 7.55 f/w.

roll core version number and add a global visible isp_restart function

Some major thrashing to handle building for other than NetBSD.

There is one change of note- build a list of completing commands in
ispintr and then say you're done- this avoids some re-entrancy issues
that had surfaced.

there is an (unimportant) difference between 1020 && 1020A

Update marc-pcmcia branch from trunk.

Merge scsipi branch in the mainline. This add support for ATAPI devices
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.

Update from trunk.

Update marc-pcmcia branch from trunk.

Defines and structures necessary to support the Qlogic 2100 (Fibre Channel
PCI card); Some additional defines to try and manage various flavors of
the SCSI host adapters (parameters for various SYNC modes).

Updates for new scsipi subsystem. Actally known to work on i386 and sparc.

- Simplify mailbox DMA setup, allowing the front-ends to allocate the
  mailbox storage in a way they see fit.
- Define macros to index and size the request and result queue entries.

Need a bus/platform specific clock speed variable.

Make the microcode table const.

NetBSD RCS ID tweaks, a few comment block tweaks.  Also, make copyright
notices consistent (per Matt Jacob).
