2298c14c62 Fix RELENG_4 code version- isp_roles wasn't getting initialized so
it ended up defaulting to ISP_ROLE_NONE. My testing hadn't caught it
because I was deliberatly setting role via ioctl.

Thanks to user Toni for lending me an alpha to test this on.

1e6fdb7e32 Fix 2KLOGIN code to specify *ibits* (not *obits*) so that the
options field in register 10 will be deterministic, not random.

Correct the number of input bits for EXECUTE_FIRMWARE 0..1 to
0..2- the 2322 and 24XX cards use mailbox register 2 to specify
whether the f/w being executed is freshly loaded or not.

Correct the number of input bits for {READ,WRITE}_RAM_WORD_EXTENDED
so that register 8 gets picked up.

Fix the indexing and offset for the 2322 f/w download so that it
correctly puts the different code segments where they belong.

Move VERIFY_CHECKSUM to be the 'else' clause to 2322 f/w downloads-
the EXECUTE_FIRMWARE command for 2322 and 24XX cards will tell you
if the f/w checksum is incorrect and VERIFY_CHECKSUM only works for
RISC SRAM address < 64K so you can only do a VERIFY_CHECKSUM on the
first of the 3 f/w segments for the 2322.

Shorten the delay for the continuation mailbox commands- 1ms is
ridiculous (100us is more likely).

All of the more or less is really only for the 2322/6322 cards.

9a5af41076 Convert isp(4) and ispfw(4) to use firmware(9) to manage firmware
loading for the QLogic cards.

Because isp(4) exists before the root is mounted, it's not really
possible for us to use the kernel's linker to load modules directly
from disk- that's really too bad.

However, the this is still a net win in in that the firmware has
been split up on a per chip (and in some cases, functionality)
basis, so the amount of stuff loaded *can* be substantially less
than the 1.5MB of firmware images that ispfw now manages. That is,
each specific f/w set is now also built as a module. For example,
QLogic 2322 f/w is built as isp_2322.ko and Initiator/Target 1080
firmware is built as isp_1080_it.ko.

For compatibility purposes (i.e., to perturb folks the least), we
also still build all of the firmware as one ispfw.ko module.

This allows us to let 'ispfw_LOAD' keep on working in existing
loader.conf files. If you now want to strip this down to just
the firmware for your h/w, you can then change loader.conf to
load the f/w you specifically want.

We also still allow for ispfw to be statically built (e.g., for
PAE and sparc64).

Future changes will look at f/w unloading and also role switching
that then uses the kernel linker to load different ips f/w sets.

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.

51effc8cd5 Actually, no, I had it wrong in 1.109. The arguments to bus_dma_create_tag
are bus_addr_t, not bus_size_t.

In any case, turn off DAC support entirely until it is revamped to actually
work *correctly* for 64 bit platforms (not using a PAE definition and for
both initiator and target mode).

8d727356c6 - Don't shift the clock frequency in MHz left by 8 before assigning it
to sbus_mdvec.dv_clock as sbus_mdvec.dv_clock is meant to be specified
  in MHz. While this was a bug it shouldn't have affected FreeBSD/sparc64
  as sbus_mdvec.dv_clock is used to limit the clock rate of chips when
  a machine isn't able to support them at maximum speed which isn't the
  case for sun4u machines.
- Remove the code that checks whether the clock frequency returned by
  sbus_get_clockfreq() is 0 and falls back to 25MHz if it is as that's
  already done in sbus(4).

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.

a5f50ef9e4 netchild's mega-patch to isolate compiler dependencies into a central
place.

This moves the dependency on GCC's and other compiler's features into
the central sys/cdefs.h file, while the individual source files can
then refer to #ifdef __COMPILER_FEATURE_FOO where they by now used to
refer to #if __GNUC__ > 3.1415 && __BARC__ <= 42.

By now, GCC and ICC (the Intel compiler) have been actively tested on
IA32 platforms by netchild.  Extension to other compilers is supposed
to be possible, of course.

26280d88d7 - Introduce an ofw_bus kobj-interface for retrieving the OFW node and a
subset ("compatible", "device_type", "model" and "name") of the standard
  properties in drivers for devices on Open Firmware supported busses. The
  standard properties "reg", "interrupts" und "address" are not covered by
  this interface because they are only of interest in the respective bridge
  code. There's a remaining standard property "status" which is unclear how
  to support properly but which also isn't used in FreeBSD at present.
  This ofw_bus kobj-interface allows to replace the various (ebus_get_node(),
  ofw_pci_get_node(), etc.) and partially inconsistent (central_get_type()
  vs. sbus_get_device_type(), etc.) existing IVAR ones with a common one.
  This in turn allows to simplify and remove code-duplication in drivers for
  devices that can hang off of more than one OFW supported bus.
- Convert the sparc64 Central, EBus, FHC, PCI and SBus bus drivers and the
  drivers for their children to use the ofw_bus kobj-interface. The IVAR-
  interfaces of the Central, EBus and FHC are entirely replaced by this. The
  PCI bus driver used its own kobj-interface and now also uses the ofw_bus
  one. The IVARs special to the SBus, e.g. for retrieving the burst size,
  remain.
  Beware: this causes an ABI-breakage for modules of drivers which used the
  IVAR-interfaces, i.e. esp(4), hme(4), isp(4) and uart(4), which need to be
  recompiled.
  The style-inconsistencies introduced in some of the bus drivers will be
  fixed by tmm@ in a generic clean-up of the respective drivers later (he
  requested to add the changes in the "new" style).
- Convert the powerpc MacIO bus driver and the drivers for its children to
  use the ofw_bus kobj-interface. This invloves removing the IVARs related
  to the "reg" property which were unused and a leftover from the NetBSD
  origini of the code. There's no ABI-breakage caused by this because none
  of these driver are currently built as modules.
  There are other powerpc bus drivers which can be converted to the ofw_bus
  kobj-interface, e.g. the PCI bus driver, which should be done together
  with converting powerpc to use the OFW PCI code from sparc64.
- Make the SBus and FHC front-end of zs(4) and the sparc64 eeprom(4) take
  advantage of the ofw_bus kobj-interface and simplify them a bit.

which is really a bogus loop id. Then when we turned around to
reset ourselves, the firmware would reject the ICB_INIT request
because the loop id was bogus. *sputter*

f6b1c44d1f Mega busdma API commit.
Add two new arguments to bus_dma_tag_create(): lockfunc and lockfuncarg.
Lockfunc allows a driver to provide a function for managing its locking
semantics while using busdma.  At the moment, this is used for the
asynchronous busdma_swi and callback mechanism.  Two lockfunc implementations
are provided: busdma_lock_mutex() performs standard mutex operations on the
mutex that is specified from lockfuncarg.  dftl_lock() is a panic
implementation and is defaulted to when NULL, NULL are passed to
bus_dma_tag_create().  The only time that NULL, NULL should ever be used is
when the driver ensures that bus_dmamap_load() will not be deferred.
Drivers that do not provide their own locking can pass
busdma_lock_mutex,&Giant args in order to preserve the former behaviour.

sparc64 and powerpc do not provide real busdma_swi functions, so this is
largely a noop on those platforms.  The busdma_swi on is64 is not properly
locked yet, so warnings will be emitted on this platform when busdma
callback deferrals happen.

If anyone gets panics or warnings from dflt_lock() being called, please
let me know right away.

316ec49abd Some kernel threads try to do significant work, and the default KSTACK_PAGES
doesn't give them enough stack to do much before blowing away the pcb.
This adds MI and MD code to allow the allocation of an alternate kstack
who's size can be speficied when calling kthread_create.  Passing the
value 0 prevents the alternate kstack from being created.  Note that the
ia64 MD code is missing for now, and PowerPC was only partially written
due to the pmap.c being incomplete there.
Though this patch does not modify anything to make use of the alternate
kstack, acpi and usb are good candidates.

fecfd395b0 If we're using ancient (pre 1.17.0) 2100 f/w (for the cards that cannot
load f/w images > 0x7fff words), set ISP_FW_ATTR_SCCLUN. We explicitly
don't believe we can find attributes if f/w is < 1.17.0, so we have to
set SCCLUN for the 1.15.37 f/w we're using manually- otherwise every
target will replicate itself across all 16 supported luns for non-SCCLUN
f/w.

Correctly set things up for 23XX and either fast posting or ZIO. The
23XX, it turns out, does not support RIO. If you put a non-zero value
in xfwoptions, this will disable fast posting. If you put ICBXOPT_ZIO
in xfwoptions, then the 23XX will do interrupt delays but post to the
response queue- apparently QLogic *now* believes that reading multiple
handles from registers is less of a win than writing (and delaying)
multiple 64 byte responses to the response queue.

At the end of taking a a good f/w crash dump, send the ISPASYNC_FW_DUMPED

af2d254da9 Remove the 'bogus registrant' hack for fabric searches. It really
turns out that there's something of a hole in our new fabric name
server stuff.  We ask the name server for entities that have
registered as a specific type.  That type is FC-SCSI. If the entity
hasn't performed a REGISTER FC4 TYPES, the fabric nameserver won't
return it.

This brings this driver to a bit of a fork in the road as to what
the right thing to do is. For servicing the needs of accessing
FC-SCSI devices, this method is fine, and to be preferred. It is
extremely unlikely we're interested in fabric devices that *don't*
register correctly. If I ever get around to adding an FC-IP stack,
then asking for devices that have registers as FC-IP types is also
the right thing to do.

So- asking the fabric nameserver for a specific type is fine, *as
long as you are only interested in specific types*. If, on the other
hand, you want to create (as for management tool support) a picture
of everything on the fabric, this is *not* so fine. There are a
large class of FC-SCSI *initiators* who *don't* correctly register,
so we never will *see* them.

Is this a problem? Yes, but only a little one. If we want to do such
management tool support, we should probably run a *different* fabric
nameserver query algorithm. Better yet, we should talk to the management
nameserver in Brocade switches instead of the standard FC-GS-2 fabric
nameserver (which can be unwieldy).

Other changes: if we've overrrides marked, don't set some default
values from reading NVRAM. This allows us to override things like
EXEC throttle without having to ignore NVRAM entirely.

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

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.

c748b5e634 Explicitly decode GetAllNext SNS Response back *as*

2001-12-11 21:58:04 +00:00
Matt Jacob
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).

Remove some bogus ISP_UNLOCK calls. *Whap*.

No longer require that somebody do a lun enable on the wildcard device
to enable target mode. They are, in fact, orthogonal. A wildcard open
is a statement that somebody upstream is willing to accept commands which
are otherwise unrouteable. Now, for QLogic regular SCSI target mode, this
won't matter for a damn because we'll never see ATIOs for luns we haven't
enabled (are listening for, if you will). But for SCCLUN fibre channel
SCSI, we get all kinds of ATIOs. We can either reflect them back here
with minimal info (which is isp_target.c:isp_endcmd() is for), or the
wildcard device (nominally targbh) can handle them.

Do further checking against firmware attributes to see whether we can,
in fact, support target mode in Fibre Channel. For now, require SCCLUN
f/w to supoprt FC target mode.

This is an awful lot of change, but target mode *still* isn't quite right.

23ac1fce7b Note for ATIOs returned because of BDRs or Bus Resets for which bus this
applies to.  Do more bus # foo things.

Acknowledge Immediate Notifies right away prior to throwing events upstream
(where they're currently being ignored, *groan*)

Capture ASYNC_LIP_F8 as with ASYNC_LIP_OCCURRED. Don't percolate them
upstream as if they were BUS RESETS- they're not.

b96934e89a If we're on an interrupt stack, mark things so that we don't try
and cv_wait for mailbox commands to complete if we start them from
here.

Fix residuals for target mode such that we only check the residual and
set it in the CTIO if this is the last CTIO (when we're sending status).

f6a3bcf86c I don't know what I was thinking- if I have two separate busses on on
SIM (as is true for the 1280 and the 12160), then I have to have separate
flags && status for *both* busses. *Whap*.

Implement condition variables for coordination with some target mode
events. It's nice to use these and not panic in obscure little places
in the kernel like 'propagate_priority' just because we went to sleep
holding a mutex, or some other absurd thing.

d82b6503a9 Because we now store SCCLUN capabilities in firmware attributes, get
rid of the silly test of isp_maxluns > 16 and use the attibutes directly.

181640a81c Clarify issues about whether we have SCCLUN (65535 luns) or non-SCCLUN (16
luns) firmware for the Fibre Channel cards.

We used to assume that if we didn't download firmware, we couldn't know
what the firmware capability with respect to SCCLUNs is- and it's important
because the lun field changes in the request queue entry based upon which
firmware it is.

At any rate, we *do* get back firmware attributes in mailbox register 6
when we do ABOUT FIRMWARE for all 2200/2300 cards- and for 2100 cards
with at least 1.17.0 firmware. So- we now assume non-SCCLUN behaviour
for 2100 cards with firmware < 1.17.0- and we check the firmware attributes
for other cards (loaded firmware or not).

This also allows us to get rid of the crappy test of isp_maxluns > 16-
we simply can check firmware attributes for SCCLUN behaviour.

This required an 'oops' fix to the outgoing mailbox count field for
ABOUT FIRMWARE for FC cards.

Also- while here, hardwire firmware revisions for loaded code for SBus
cards. Apparently the 1.35 or 1.37 f/w we've been loading into isp1000
just doesn't report firmware revisions out to mailbox regs 1, 2 and 3
like everyone else. Grumble. Not that this fix hardly matters for FreeBSD.
