624539bb38 The check_extport() function appears to have some new code in it that checks
the scratch RAM for data normally found in the SEEPROM (presumably in the
event that the SEEPROM is unavailable or can't be read). This code causes
a spontaneous reboot on monster.osd.bsdi.com, which has an embedded aic7880
controller. The problem appears to happen either when it writes to the
SCBPTR port and then reads from the SCB_CONTROL port. Somewhere during
the inb/outb operations, the system has a heart attack and restarts.

This code looks very suspicious, particularly since it has unconditionalized
debug mesages such as "Got here!" and "And it even worked!". With this
block #ifdef'ed out, the machine boots and runs properly. I stronly suggest
that it stay #ifdef'ed out until it's properly tested.

957790c3e6 ahc_pci.c:
Disable "cache line streaming" for aic7890/91 Rev A chips.  I
	have never seen these chips fail using this feature, but
	some of Adaptec's regression tests have.

	Explicitly set "cache line streaming" to on for aic7896/97
	chips.  This was happening before, but this documents the
	fact that these chips will not function correctly without
	CACHETHEEN set.

aic7xxx.h:
	Add new bug types.

	Fix a typo in a comment.

aic7xxx.reg:
	Add a definition for the SHVALID bit in SSTAT3 for Ultra2/3
	chips.  This bit inicates whether the bottom most (current)
	element in the S/G fifo has exhausted its data count.

aic7xxx.seq:
	Be more careful in how we turn off the secondary DMA channel.
	Being less careful may hang the PCI bus arbitor that negotiates
	between the two DMA engines.

	Remove an unecessary and incorrect flag set operation in
	the overrun case.

	On Ultra2/3 controllers, clear the dma FIFO before starting
	to handle an overrun.  We don't want any residual bytes from
	the beginning of the overrun to cause the code that shuts
	down the DMA engine from hanging because the FIFO is not
	(and never will be) empty.

	If the data fifo is empty by the time we notice that a
	read transaction has completed, there is no need to
	hit the flush bit on aic7890/91 hardware that will not
	perform an auto-flush.  Skip some cycles by short circuiting
	the manual flush code in this case.

	When transitioning out of data phase, make sure that we
	have the next S/G element loaded for the following
	reconnect if there is more work to do.  The code
	would do this in most cases before, but there was
	a small window where the current S/G element could
	be exhausted before our fetch of the next S/G element
	completed.  Since the S/G fetch is already initiated
	at this point, it makes sense to just wait for the
	segment to arrive instead of incuring even more latency
	by canceling the fetch and initiating it later.

	Fast path the end of data phase handling for the last
	S/G segment.   In the general case, we might have
	worked ahead a bit by stuffing the S/G FIFO with
	additional segments.  If we stop before using them
	all, we need to fixup our location in the S/G stream.
	Since we can't work past the last S/G segment, no
	fixups are ever required if we stop somewhere in
	that final segment.

	Fix a little buglet in the target mode dma bug handler.
	We were employing the workaround in all cases instead
	of only for the chips that require it.

	Fix the cause of SCB timeouts and possible "lost data"
	during read operations on the aic7890.  When sending
	a data on any Ultra2/3 controller, the final segment
	must be marked as such so the FIFO will be flushed and
	cleaned up correctly when the transfer is ended.  We
	failed to do this for the CDB transfer and so, if
	the target immediately transfered from command to data
	phase without an intervening disconnection, the first
	segment transferred would be any residual bytes from
	the cdb transfer.  The Ultra160 controllers for some
	reason were not affected by this problem.

Many Thanks to Tor Egge for bringing the aic7890 problem
to my attention, providing analysis, as well as a mechanism
to reproduce the problem.

f94bf02fdb Properly handle the case where the residual is 0, but, as the target
didn't bother to send a saved data pointers after the last transfer,
is not recorded in sgptr.  This was only a problem if the target
reported non-zero status as we always check the residual in that case.

c27eebfde8 aic7xxx.c:
Correct the BUILD_TCL macro.  It was placing the target id
	in the wrong bits.  This was only an issue for adapters that
	do not perform SCB paging (aha-3940AUW for instance).

	Don't bother inlining ahc_index_busy_tcl.  It is never
	used in a performance critical path and is a bit chunky.

	Correct ahc_index_busy_tcl to deal with "busy target tables"
	embedded in the latter half of 64byte SCBs.

	Don't initialize the busy target table to its empty state
	until after we have finished extracting configuration
	information from chip SRAM.  In the common case of using
	16 bytes of chip SRAM to do untagged target lookups,
	we were trashing the last 8 targets configuration data.
	(actually only target 8 because of the bug in the
	BUILD_TCL macro).

	Cram the "bus reset delivered" message back under bootverbose.

	Fix the cleanup of the SCB busy target table when aborting
	commands.  If the lun is wildcarded, we must loop through
	all possible luns.

aic7xxx.h:
	Only bother supporting 64 luns right now.  It doesn't seem
	like either this driver or any peripherals will be doing
	information unit transfers (where the lun number is a
	32 bit integer) any time soon.

aic7xxx.seq:
	Fix support for the aic7895.  We must flush the data
	FIFO if performing a manual transfer that is not
	a multiple of 8 bytes.  We were doing this quite
	regularly for embedded cdbs.

	Manaually flush the fifo on earlier adapters when
	dealing with embedded cdbs too.  We were stuffing
	the FIFO with 16 bytes instead, but triggering
	the flush is more efficient and allows us to
	remove two instructions from the "copy_to_fifo"
	routine.

aa6dfd9d3d o Convert to <inttypes.h> style fixed sized types to facilitate porting to
other systems.

 o Normalize copyright text.

 o Clean up probe code function interfaces by passing around a single
   structure of common arguments instead of passing "too many" args
   in each function call.

 o Add support for the AAA-131 as a SCSI adapter.

 o Add support for the AHA-4944 courtesy of "Matthew N. Dodd" <winter@jurai.net

 o Correct manual termination support for PCI cards.  The bit definitions
   for manual termination control in the SEEPROM were incorrect.

 o Add support for extracting NVRAM information from SCB 2 for BIOSen
   that use this mechanism to pass this data to OS drivers.

 o Properly set the STPWLEVEL bit in PCI config space based on the
   setting in an SEEPROM.

 o Go back to useing 32byte SCBs for all controllers.  The current
   firmware allows us to embed 12byte cdbs on all controllers in
   a 32byte SCB, and larger cdbs are rarely used, so it is a
   better use of this space to offer more SCBs (32).

 o Add support for U160 transfers.

 o Add an idle loop executed during data transfers that prefetches
   S/G segments on controllers that have a secondary DMA engine
   (aic789X).

 o Improve the performance of reselections by avoiding an extra
   one byte DMA in the case of an SCB lookup miss for the reselecting
   target.  We now keep a 16byte "untagged target" array on the card
   for dealing with untagged reselections.  If the controller has
   external SCB ram and can support 64byte SCBs, then we use an
   "untagged target/lun" array to maximize concurrency.  Without
   external SCB ram, the controller is limited to one untagged
   transaction per target, auto-request sense operations excluded.

 o Correct the setup of the STPWEN bit in SXFRCTL1.  This control
   line is tri-stated until set to one, so set it to one and then
   set it to the desired value.

 o Add tagged queuing support to our target role implementation.

 o Handle the common cases of the ignore wide residue message
   in firmware.

 o Add preliminary support for 39bit addressing.

 o Add support for assembling on big-endian machines.  Big-endian
   support is not complete in the driver.

 o Correctly remove SCBs in the waiting for selection queue when
   freezing a device queue.

 o Now that we understand more about the autoflush bug on the
   aic7890, only use the workaround on devices that need it.

 o Add a workaround for the "aic7890 hangs the system when you
   attempt to pause it" problem.  We can now pause the aic7890
   safely regardless of what instruction it is executing.

ff58fb8420 o Correct the offsets into the syncrate table for paritcular
negotiation features (DT, ULTRA2, ULTRA, FAST).  The offsets
  where not properly updated when the DT entry was added and so
  the driver could attempt to negotiate a speed faster than that
  supported by the target device or even requested by the user
  via SCSI-Select settings. *

o Update the target mode incoming command queue kernel index value
  ever 128 commands instead of 32.  This means that the kernel will
  always try to keep its index (as seen on the card - the kernel may
  actually have cleared more space) 128 commands ahead of where the
  sequencer is adding entries.

o Use the HS_MAILBOX register instead of the KERNEL_TQINPOS location
  in SRAM to indicate the kernel's target queue possition on Ultra2
  cards.  This avoids the "pause bug" on these cards and also turns
  out to be much more efficient.

o When enabling or disabling a particular target id for target mode,
  make sure that the taret id in the SCSIID register does not
  reference an ID that is not to receive target selections.  This
  is only an issue on chips that support the multiple target id
  feature where the value in SCSIID will still affect selection
  behavior regardless of the values in the target id bit field
  registers.

o Remove some target mode debugging printfs.

o Make sure that the sense length reported in ATIO commands is
  always zero.  This driver does not, yet, report HBA generated
  sense information for accepted commands.

o Honor the CAM_TIME_INFINITY and CAM_TIME_DEFAULT values for
  the CCB timeout field.

o Make the driver compile with AHC_DEBUG again.

85ac786b13 Kill the "unpause_always" argument to unpause_sequencer(). The reasons
for optimizing the unpause operation no-longer exist, and this is much
safer.

When restarting the sequencer, reconstitute the free SCB list on the card.
This deals with a single instruction gap between marking the SCB as free
and actually getting it onto the free list.

Reduce the number of transfer negotiations that occur.  In the past, we
renegotiated after every reported check condition status.  This ensures
that we catch devices that have unexpectidly reset.  In this situation,
the target will always report the check condition before performing a
data-phase.  The new behavior is to renegotiate for any check-condition where
the residual matches the orginal data-length of the command (including
0 length transffers).  This avoids renegotiations during things like
variable tape block reads, where the check condition is reported only
to indicate the residual of the read.

Revamp the parity error detection logic.  We now properly report and
handle injected parity errors in all phases.  The old code used to hang
on message-in parity errors.

Correct the reporting of selection timeout errors to the XPT.  When
a selection timeout occurs, only the currently selecting command
is flagged with SELTO status instead of aborting all currently active
commands to that target.

Fix flipped arguments in ahc_match_scb and in some of the callers of this
routine.  I wish that gcc allowed you to request warnings for enums passed
as ints.

Make ahc_find_msg generically handle all message types.

Work around the target mode data-in wideodd bug in all non-U2 chips.
We can now do sync-wide target mode transfers in target mode across the
hole product line.

Use lastphase exclusively for handling timeouts.  The current phase
doesn't take the bus free state into account.

Fix a bug in the timeout handler that could cause corruption of the
disconnected list.

When sending an embedded cdb to a target, ensure that we start on a
quad word boundary in the data-fifo.  It seems that unaligned stores
do not work correctly.

	This makes data-overrun and other error reporting more

7debf5e75e Fix a long standing bug in the auto-termination control settings for
the aic7890/91/96/97 cards.  This could cause the system to go into
a long retry/recovery loop during probe.

Fix the alignment argument to bus_dma_tag_create().

Don't set the CACHETHEN bit in dscommand0 for Ultra2 controllers
until we know more about its behavior.  The description for this
bit makes it sound like it could cause problems with certain
PCI chipsets.

086646f7c6 Properly set the alignment argument to bus_dma_tag_create(). If we
don't care about the alignment, set it to 1, meaning single byte alignment.

0d6ab4a16a Move the specification of EDGE/LEVEL triggered interrupts to
eisa_add_intr() which now takes an additional arguement (one of
EISA_TRIGGER_LEVEL or EISA_TRIGGER_EDGE).

The flag RR_SHAREABLE has no effect when passed to
bus_alloc_resource(dev, SYS_RES_IRQ, ...) in an EISA device context as
the eisa_alloc_resource() call (bus_alloc_resource method) now deals
with this flag directly, depending on the device ivars.

This change does nothing more than move all the 'shared = inb(foo + iobsse)'
nonesense to the device probe methods rather than the device attach.

Also, print out 'edge' or 'level' in the IRQ announcement message.

51064aaaf8 Ignore subvendor and subdevice ids for all ai7880 parts. These chips
only support 'mirroring' the vendor and device ids, so we don't
lose any information.  Certain revisions of the aic7880 will not
perform the mirroring so to match all possiblities would double
the number of table entries.  This change also allows us to match
things like the 2944B which I missed in the original table.
