0a70657fcc Make this an MP safe driver but also still be multi-release.
Seems to work on RELENG_4 through -current and also on sparc64
now. There may still be some issues with the auto attach/detach
code to sort out.

2b83592fdc Remove Giant from CAM. Drivers (SIMs) now register a mutex that CAM will
use to synchornize and protect all data objects that are used for that
SIM.  Drivers that are not yet MPSAFE register Giant and operate as
usual.  RIght now, no drivers are MPSAFE, though a few will be changed
in the coming week as this work settles down.

The driver API has changed, so all CAM drivers will need to be recompiled.
The userland API has not changed, so tools like camcontrol do not need to
be recompiled.

9a1b0d43c2 Temporarily desupport simultaneous target and initiator mode.
When the linux port changes were imported which split the
target command list to be separate from the initiator command
list and the handle format changed to encode a type in the handle
the implications to the function isp_handle_index (which only
the NetBSD/OpenBSD/FreeBSD ports use) were overlooked.

The fault is twofold: first, the index into the DMA maps
in  isp_pci is wrong because a target command handle with
the type bit left in place caused a bad index (and panic)
into dma map. Secondly, the assumption of the array
of DMA maps in either PCS or SBUS attachment structures is
that there is a linear mapping between handle index and
DMA map index. This can no longer be true if there are
overlapping index spaces for initiator mode and target
mode commands.

These changes bandaid around the problem by forcing us
to not have simultaneous dual roles and doing the appropriate
masking to make sure things are indexed correctly. A longer
term fix is being devloped.

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.

336b56124b There is a problem in setting/getting 'options'- if we check things
early, we haven't set board type, so we can't correctly check for
some options.  Fix this by splitting option setting/getting into
generic, pci and then later board specific, option setting/getting.

This was noticed when setting 'iid' (or 'hard loop id') didn't work
all of a sudden.

33d5497079 Cleanup and document the implementation of firmware(9) based on
a version that i posted earlier on the -current mailing list,
and subsequent feedback received.

The core of the change is just in sys/firmware.h and kern/subr_firmware.c,
while other files are just adaptation of the clients to the ABI change
(const-ification of some parameters and hiding of internal info,
so this is fully compatible at the binary level).

In detail:
- reduce the amount of information exported to clients in struct firmware,
  and constify the pointer;

- internally, document and simplify the implementation of the various
  functions, and make sure error conditions are dealt with properly.

The diffs are large, but the code is really straightforward now (i hope).

Note also that there is a subtle issue with the implementation of
firmware_register(): currently, as in the previous version, we just
store a reference to the 'imagename' argument, but we should rather
copy it because there is no guarantee that this is a static string.
I realised this while testing this code, but i prefer to fix it in
a later commit -- there is no regression with respect to the past.

Note, too, that the version in RELENG_6 has various bugs including
missing locks around the module release calls, mishandling of modules
loaded by /boot/loader, and so on, so an MFC is absolutely necessary
there.  I was just postponing it until this cleanup to avoid doing
things twice.

3cce220cba Remove dependency on ispfw and firmware as modules.
Either they're there early and the ispfw sets have
registered themselves, or they're not.

The module dependency stuff isn't quite what we want
anyway. If the user doesn't want the load placed on
system memory by loading the firmware, they don't
specify it to be loaded (either by being linked in
or via being a module to be loaded and then hooked
in with firmware(9)). It doesn't then make sense to
then override what they want by pulling it in anyway.

This might be able to work if we were able to pull in
just exactly what we needed for the card we have- but
that's an optimization left for the future.

f7c631bcf0 Push things closer to path failover by implementing loop down and
gone device timers and zombie state entries. There are tunables
that can be used to select a number of parameters.

loop_down_limit - how long to wait for loop to come back up before
declaring
all devices dead (default 300 seconds)

gone_device_time- how long to wait for a device that has appeared
to leave the loop or fabric to reappear (default 30 seconds)

Internal tunables include (which should be externalized):

quick_boot_time- how long to wait when booting for loop to come up

change_is_bad- whether or not to accept devices with the same
WWNN/WWPN that reappear at a different PortID as being the 'same'
device.

Keen students of some of the subtle issues here will ask how
one can keep devices from being re-accepted at all (the answer
is to set a gone_device_time to zero- that effectively would
be the same thing).

fa9ed86506 The first of 3 major steps to move the CAM layer forward to using
the CAM_NEW_TRAN_CODE that has been in the tree for some years now.

This first step consists solely of adding to or correcting
CAM_NEW_TRAN_CODE pieces in the kernel source tree such
that a both a GENERIC (at least on i386) and a LINT build
with CAM_NEW_TRAN_CODE as an option will compile correctly
and run (at least with some the h/w I have).

After a short settle time, the other pieces (making
CAM_NEW_TRAN_CODE the default and updating libcam
and camcontrol) will be brought in.

This will be an incompatible change in that the size of structures
related to XPT_PATH_INQ and XPT_{GET,SET}_TRAN_SETTINGS change
in both size and content. However, basic system operation and
basic system utilities work well enough with this change.

are seperate IOMMU's for each PCI bus...  For all other arches, it will
end up returning NULL, which makes it a no-op...

Convert a few drivers (the ones we've been working w/ on sun4v) to the

tag of NULL, w/ bus_get_dma_tag(dev), though dev is usually different for
each driver, and will require hand inspection...

Correct the number of input bits for EXECUTE_FIRMWARE 0..1 to

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

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.

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

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.

ac9d0a02cf Fix longstanding buglet- for centrally handled CTIO2s we were checking the wrong
bit for this being the  last CTIO2.  It didn't matter since it really was the
last CTIO2 and the resources recycled, but still....

Add in CTIO3 define for future DAC work.

e23df011da If we have ISP_ROLE_INITIATOR set, make sure that we clear ICBOPT_INI_DISABLE
from the fwoptions. Likewise, we *set* ICBOPT_INI_DISABLE if we don't have
initiator role.

081a1c2536 Turn off ISP_SMPLOCK- not to be turned on again.
Until we can have perfect knowledge that all callers above us think it's okay
for us to sleep, releasing *our* locks of course, we don't dare try and sleep.

70cd771337 The present defaults for the open and close for device drivers which
provide no methods does not make any sense, and is not used by any
driver.

It is a pretty hard to come up with even a theoretical concept of
a device driver which would always fail open and close with ENODEV.

Change the defaults to be nullopen() and nullclose() which simply
does nothing.

Remove explicit initializations to these from the drivers which
already used them.

28f0575cf1 On reset, make sure that we have some parameters set correctly. This
fixes a longstanding issue WRT resetting the chip after startup- it
would fail if we were connected as an F-port to a switch. If we
were connected as an F-port, we got assigned a hard loop ID of 255,
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*

Minor fixlet from somebody in NetBSD with too much time on their
hands (dma -> DMA).

e43e17a2e6 Move the inclusion of <machine/ofw_machdep.h> after the inclusion of
<dev/ofw/openfirm.h> to allow the former to contain prototypes that
use types defined in the latter.

65ff1249a0 Revert previous commit. Violates Maintainer (O'Brien knows how to
reach me directly), but more importantly, breaks compiles on
non-FreeBSD platforms.
