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.

66cbe912a9 Remove ISP_DMA_ADDR_T definition.
Instead, based upon whether ISP_DAC_SUPPORTED is defined, typedef
isp_dma_addr_t appropriately.

If ISP_DAC_SUPPORTRED is defined, the DMA_WD2/DMA_WD3 macros do something
useful, else they define to '0'.

435a93378f Re-specify the bus space creation such that if we have ISP_DAC_SUPPORTED
defined, we set the address space limitation to BUS_SPACE_UNRESTRICTED,
otherwise to BUS_SPACE_MAXADDR_32BIT.

If we have a 1240, ULTRA2 or better, or an FC card, the boundary limit
is BUS_SPACE_UNRESTRICTED and segment limit is BUS_SPACE_MAXADDR_32BIT.

The older 1020/1040 cards have boundary and segment limits of
BUS_SPACE_MAXADDR_24BIT.

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
event to the outer layers (who can then do things like wake a user
daemon to *fetch* the crash image, etc.).

fdeb9f2f66 Add get/set param ioctl support.
Remove sim queue freezes for resource shortages. I've had too many
strange race conditions where I freeze on a resource shortage but
never get unfrozen.

Consolidate the remaining sim queue freeze condition (for loopdown)
into an inline with debug messages that allows us to track problems
at ISP_LOGDEBUG0 level easier. Change a bunch of debug messages about
loop down/up conditions to ISP_LOGDEBUG0 level.

Remove dead isp_relsim code.

Change some internal flag stuff for efficiency.

Complain vociferously if we try and use our FC scratch area while it's
busy being used already (I mean, if we don't have solaris' ability
to sleep as an interrupt thread which would allow us to just use
a p/v semaphore, at least *say* when you've just borked yourself).

Add infrastructure to allow overrides of hard loopid && initiator
id from boot variables.

Fix the usual quota of silly bugs:

 + 'ktmature' needs to be per-instance. Argh.
 + When entering isp_watchdog, set intsok to zero, preserving
   old value to restore later. It's not nice to try and sleep
   from splsoftclock.
 + Fix tick overflow buglet in checking timeout value.

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.

themeselves with the fabric nameserver.

570c7a3f78 Add support for ISP_FC_GETHINFO, which returns current connection
topology, speed, loopid, WWPN/WWNN, etc.

Beef up target mode. Add isp_handle_platform_notify_scsi and
isp_handle_platform_notify_fc platform handlers to handle immediate
notifies (isp_handle_platform_notify_scsi is still stubbed out).

In implementation of isp_handle_platform_notify_fc, for IN_ABORT_TASK,
peel off a pending XPT_IMMED_NOTIFY and call xpt_done on it and hope
that somebody upstream is listening.

Make sure on final CTIO2s that we set residual correctly. These are
absolutely crucial. Make sure we set relative offset for each CTIO2
based upon bytes we've already xferred. This is what the private
adjunct datat to the original ATIO is. Note state of command so
we can figure out where to find it if we get an ABORT from the firmware.

Make sure we *always* set CAM_TAG_ACTION_VALID for ATIO2s. Make sure
we keep track of the original lun.

If se sent status (or we're otherwise done with the command), don't
forget to free the adjunct structure.

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.
