This should fix some problem of SBP2 device probing.
Prior to rev 1.41, we keep writing the register while bus reset phase.
But in rev 1.41, we ignore successive bus reset events and some chips seem to
clear the register after we write to it.
Tested by: Michael Reifenberger <root@nihil.reifenberger.com>
Clear the LQICRC_NLQ status should it pop up after we have
already handled the SCSIPERR. During some streaming operations
this status can be delayed until the stream ends. Without this
change, the driver would complain about a "Missing case in
ahd_handle_scsiint".
In the LQOBUSFREE handler...
Don't return the LQOMGR back to the idle state until after
we have cleaned up ENSELO and any status related to this
selection. The last thing we need is the LQO manager starting
another select-out before we have updated the execution queue.
It is not clear whether the LQOMGR would, or would not
start a new selection early.
Make sure ENSELO is off prior to clearing SELDO by flushing
device writes.
Move assignment of the next target SCB pointer inside of
an if to make the code clearer. The effect is the same.
Dump card state in both "Unexpected PKT busfree" paths.
In ahd_reset(), set the chip to SCSI mode before reading SXFRCTL1.
That register only exists in the SCSI mode. Also set the mode
explicitly to the SCSI mode after chip reset due to paranoia.
Re-arrange code so that SXFRCTL1 is restored as quickly after the
chip reset as possible.
S/G structurs must be 8byte aligned. Make this official by saying
so in our DMA tag.
Disable CIO bus stretch on MDFFSTAT if SHVALID is about to come
true. This can cause a CIO bus lockup if a PCI or PCI-X error
occurs while the stretch is occurring - the host cannot service
the PCI-X error since the CIO bus is locked out and SHVALID will
never resolve. The stretch was added in the Rev B to simplify the
wait for SHVALID to resolve, but the code to do this in the open
source sequencer is so simple it was never removed.
Consistently use MAX_OFFSET for the user max syncrate set from
non-volatile storage. This ensures that the offset does not
conflict with AH?_OFFSET_UNKNOWN.
Have ahd_pause_and_flushwork set the mode to ensure that it has
access to the registers it checks. Also modify the checking of
intstat so that the check against 0xFF can actually succeed if
the INT_PEND mask is something other than 0xFF. Although there
are no cardbus U320 controllers, this check may be needed to
recover from a hot-plug PCI removal that occurs without informing
the driver.
Fix a typo. sg_prefetch_cnt -> sg_prefetch_align. This fixes
an infinite loop at card initialization if the cacheline size is 0.
aic79xx.h:
Add AHD_EARLY_REQ_BUG bug flag.
Fix spelling errors.
Include the CDB's length just after the CDB pointer in the DMA'ed
CDB case.
Change AH?_OFFSET_UNKNOWN to 0xFF. This is a value that the
curr->offset can never be, unlike '0' which we previously used.
This fixes code that only checks for a non-zero offset to
determine if a sync negotiation is required since it will fire
in the unknown case even if the goal is async.
aic79xx.reg:
Add comments for LQISTAT bits indicating their names in the 7902
data book. We use slightly different and more descriptive names
in the firmware.
Fix spelling errors.
Include the CDB's length just after the CDB pointer in the DMA'ed
CDB case.
aic79xx.seq:

Fix spelling errors.
Since we use an 8byte address and 1 byte length, shorten the size
of a block move for the legacy DMA'ed CDB case from 11 to 9 bytes.
Remove code that, assuming the abort pending feature worked, would
set MK_MESSAGE in the SCB's control byte on completion to catch
invalid reselections. Since we don't see interrupts for completed
selections, this status update could occur prior to us noticing the
SELDO. The "select-out" queue logic will get confused by the
MK_MESSAGE bit being set as this is used to catch packatized
connections where we select-out with ATN. Since the abort pending
feature doesn't work on any released controllers yet, this code was
never executed.
Add support for the AHD_EARLY_REQ_BUG. Don't ignore persistent REQ
assertions just because they were asserted within the bus settle delay
window. This allows us to tolerate devices like the GEM318 that
violate the SCSI spec.
Remove unintentional settnig of SG_CACHE_AVAIL. Writing this bit
should have no effect, but who knows...
On the Rev A, we must wait for HDMAENACK before loading additional
segments to avoid clobbering the address of the first segment in
the S/G FIFO. This resolves data-corruption issues with certain
IBM (now Hitachi) and Fujitsu U320 drives.
Rearrange calc_residual to avoid an extra jmp instruction.
On RevA Silicon, if the target returns us to data-out after we
have already trained for data-out, it is possible for us to
transition the free running clock to data-valid before the required
100ns P1 setup time (8 P1 assertions in fast-160 mode). This will
only happen if this L-Q is a continuation of a data transfer for
which we have already prefetched data into our FIFO (LQ/Data
followed by LQ/Data for the same write transaction). This can
cause some target implementations to miss the first few data
transfers on the bus. We detect this situation by noticing that
this is the first data transfer after an LQ (LQIWORKONLQ true),
that the data transfer is a continuation of a transfer already
setup in our FIFO (SAVEPTRS interrupt), and that the transaction
is a write (DIRECTION set in DFCNTRL). The delay is performed by
disabling SCSIEN until we see the first REQ from the target.
Only compile in snapshot savepointers handler for RevA silicon
where it is enabled.
Handle the cfg4icmd packetized interrupt. We just need to load
the address and count, start the DMA, and CLRCHN once the transfer
is complete.
Fix an oversight in the overrun handler for packetized status
operations. We need to wait for either CTXTDONE or an overrun
when checking for an overrun. The previous code did not wait
and thus could decide that no overrun had occurred even though
an overrun will occur on the next data-valid req. Add some
comment to this section for clarity.
Use LAST_SEG_DONE instead of LASTSDONE for testing transfer
completion in the packetized status case. LASTSDONE may come up
more quickly since it only records completion on the SCSI side,
but since LAST_SEG_DONE is used everywhere else (and needs to be),
this is less confusing.
Add a missing invalidation of the longjmp address in the non-pack
handler. This code needs additional review.
aic79xx_inline.h:
Fix spelling error.
aic79xx_osm.c:
Set the cdb length for CDBs dma'ed from host memory.
Add a comment indicating that, should CAM start supporting cdbs
larger than 16bytes, the driver could store the CDB in the status

Add a table entry for the 39320A.
Added a missing comma to an error string table.
Fix spelling errors.
Move <sys/conf.h> before <sys/disk.h>.

filled by the mmap handler when the mapping was successful. The
mmap handler must now return 0 when successful, any other value
is considered as an error. Previously, returning -1 was the only
way to fail. This change thus accidentally fixes some devices
which were bogusly returning errno constants which would have been

- Automatically detect CDROM drives that can't handle 6 byte mode

We have to handle this in the cd(4) driver (where the buffers are

6 and 10 byte mode sense commands.
- Remove MODE_SENSE and MODE_SELECT translation removed in ATAPICAM
and in the umass(4) driver, since there's no way for that to work
properly.
- Add a quirk entry for CDROM drives that just hang when they get a 6
byte mode sense or mode select. The reason for the quirk must be
documented in a PR, and all quirks must be approved by
ken@FreeBSD.org. This is to make sure that we fully understand why
each quirk is needed. Once the CAM_NEW_TRAN_CODE is finished, we
should be able to remove any such quirks, since we'll know what
protocol the drive speaks (SCSI, ATAPI, etc.) and therefore whether
we should use 6 or 10 byte mode sense/select commands.
- Change the way the da(4) handles the no_6_byte sysctl. There is
now a per-drive sysctl to set the minimum command size for that
particular disk. (Since you could have multiple disks with
multiple requirements in one system.)
- Loader tunable support for all the sysctls in the da(4) and cd(4)

now allow open() to succeed no matter what, but if we don't detect
valid media, the user can only issue CDIOCCLOSE or CDIOCEJECT
ioctls.
- The media validation routine also reads the table of contents off
the drive. We use the table of contents to implement the
CDIOCPLAYTRACKS ioctl using the PLAY AUDIO MSF command. The
PLAY AUDIO TRACK INDEX command that we previously used was
deprecated after SCSI-2. It works in every SCSI CDROM I've tried,
but doesn't seem to work on ATAPI CDROM drives. We still use the
play audio track index command if we don't have a valid TOC, but
I suppose it'll fail anyway in that case.

retain symetry with aac_alloc_commans(). Since aac_alloc_commands()
allocates fib maps and places them onto the fib lists, aac_free_commands()
should reverse those operations.
o Combine two ifs with the same body with an ||.
o Switch from uintptr_t to uint32_t for fib map load operations.
The target is a uint32_t so using this type for the map load call
avoids an extra cast. uintptr_t should only be used when you need
an "int sized the same as the machine's poitner size" which is not
the case here.
o Removed the commented out M_WAITOK flag in the allocation in
aac_alloc_commands(). The kernel will only block in the allocator
if it can grow the size of the kernel. This usually results in a
page-out which could involve this aac device. Thus, sleeping here
could deadlock the machine. Assuming this operation is occurring outside
of attach time, we have enough fibs to operate anyway, so waiting for
fibs to free up is okay if not optimal.
o In aac_alloc_commands(), if we cannot dmamem_alloc additional fib
space, free the fib map.
o In aac_alloc_commands(), if we cannot create per-command dmamaps, don't
lose track of the fib map that is mapping all of the commands that we
have already released into the free pool. Instead, just cut out of
the loop and modify aac_free_commands to not attempt to free maps that
have not been allocated.
o Don't use a magic number when pre-allocating fibs.
o Use PAGE_SIZE to allocate in page sized chunks instead of an

similar patch has been in 4.x for a while, but is more hacky there.)
For this to work, vinum has to be loaded early (e. g. from
boot/loader), for obvious reasons. If the kernel env variable
(aka. loader variable) "vinum.autostart" is set, vinum then asks the
sysctl kern.disks for all available disks in the system, and scans
them for possible vinum headers.
For statically compiled kernels, this behaviour can be obtained even
without boot/loader by using "options VINUM_AUTOSTART" (though this is
not the recommended way).
Alternatively, the 4.x way to specify "vinum.drives" is also supported.
No further hacks (like the 4.x "vinum.root" variable) are needed,
since in 5.x, mountroot() asks back at the drivers to have them
resolve the name of the root FS into a dev_t (using the dev_clone
eventhandler).
