more cleanly and consistently in all APCI, PnP BIOS, and "hint"
cases.
NOTE: this doesn't necessarily solve the problem that the PS/2
mouse is not detected after the recent ACPI update.
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.
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.

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.
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).

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.

A nsp chip does suspend I/O write by 512bytes burst write,
though the chip only has 48 bytes FIFO. The chip assert I/O WAIT
signal to PC-Card bus after the CPU writes more than 48 bytes to
the chip if the SCSI device does not respond immediately in supsend
I/O burst write. If the device does not respond for a while it might
cause PC-Card bus timeout.
The previous work around was to wait the request from SCSI device.
But there are some devices which request bytes for synchronous transfer
immediately. So current work aound is to fill 32bytes FIFO, wait for
FIFO empty and burst write 512-32 bytes for every 512 bytes block.

Add a sysctl that allows us to retrieve the ACPI CA version number as
well.
some reworking (and consequent cleanup) of the interrupt service code.
Also begin to start a cleanup of target mode support that will (eventually)
not require more inforamtion routed with the ATIO to come back with the
CTIO other than tag.
