changes is that there's now a Solaris port of this driver, so some things
in the core version had to change (not much, but some).
In order, from the top.....:
A lot of error strings are gathered in one place at the head of the file.
This caused me to rewrite them to look consistent (with respect to
things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'.
The major mailbox function, isp_mboxcmd, now takes a third argument,
which is a mask that selectively says whether mailbox command failures
will be logged. This will substantially reduce a lot of spurious noise
from the driver.
At the first run through isp_reset we used to try and get the current
running firmware's revision by issuing a mailbox command. This would
invariably fail on alpha's with anything but a Qlogic 1040 since SRM
doesn't *start* the f/w on these cards. Instead, we now see whether we're
sitting ROM state before trying to get a running BIOS loaded f/w version.
All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to
isp_prt. There are seperate print levels that can be independently
set (see ispvar.h), which include debugging, etc.
All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and
RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel
cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry
indices, so we can make a 1024 entry index for them instead of the
256 entries we've had until now.
A major change it to fix isp_fclink_test to actually only wait the
delay of time specified in the microsecond argument being passed.
The problem has always been that a call to isp_mboxcmd to get he
current firmware state takes an unknown (sometimes long) amount of
time- this is if the firmware is busy doing PLOGIs while we ask
it what's up. So, up until now, the usdelay argument has been
a joke. The net effect has been that if you boot without being plugged
into a good loop or into a switch, you hang. Massively annonying, and
hard to fix because the actual time delta was impossible to know
from just guessing. Now, using the new GET_NANOTIME macros, a precise
and measured amount of USEC_DELAY calls are done so that only the
specified usecdelay is allowed to pass. This means that if the initial
startup of the firmware if followed by a call from isp_freebsd.c:isp_attach
to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000,
no more than two seconds will actually elapse before we leave concluding
that the cable is unhooked. Jeez. About time....
Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE
macro to a call to the platform supplied isp_done (sane naming).
Limit our size of request queue completions we'll look at at interrupt
time. Since we've increased the size of the Request Queue (and the
size of the Response Queue proportionally), let's not create an
interrupt stack overflow by having to keep a max completion list
(forw links are not an option because this is common code with
some platforms that don't have link space in their XS_T structures).
A limit of 32 is not unreasonable- I doubt there'd be even this many
request queue completions at a time- remember, most boards now use
fast posting for normal command completion instead of filling out
response queue entries.
In the isp_mboxcmd cleanup, also create an array of command
names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8".
Remove the isp_lostcmd function- it's been deprecated for a while.
Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus

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

timeout(9) can happen up to 1 tick early, which was causing receive

Split out softdep_flushworklist() from softdep_flushfiles() so that

Access to buffers becomes recursive so that snapshots can recursively

for the need for copy on write when flushing one of their own indirect
blocks. This eliminates a deadlock between the syncer daemon and a
process taking a snapshot.
Ensure that softdep_process_worklist() can never block because of a

MNT_WAIT was specified. The result was an unclean filesystem panic

Return a zero'ed block when reading a block that was not in use at

Clean up the debugging code that ensures that no blocks be written
on a filesystem while it is suspended. Snapshots must explicitly
label the blocks that they are writing during the suspension so that
they do not cause a `write on suspended filesystem' panic.
Reorganize ffs_copyonwrite() to eliminate a deadlock and also to
prevent a race condition that would permit the same block to be
copied twice. This change eliminates an unexpected soft updates

The solution is to check that the header doesn't ask for part of a

VEXEC at the proper times to make the executables immutable (remove
race conditions). Also, the ELF format specifiies header entries

lock up under moderate to heavy load.
The status & command fields share a 32-bit longword. The programming
API of the eepro apparently requires that you update the command field
of a transmit slot that you've already given to the card. This means
the card could be updating the status field of the same longword at
the same time. Since alphas can only operate on 32-bit chunks of
memory, both the status & command fields are loaded from memory &
operated on in registers when the following line of C is executed:
sc->cbl_last->cb_command &= ~FXP_CB_COMMAND_S;
The race is caused by the card DMA'ing up the status at just the wrong
time -- after it has been loaded into a register & before it has been
written back. The old value of the status is written back, clobbering
the status the card just DMA'ed up. The fact that the card has sent
this frame is missed & the transmit engine appears to hang.
Luckily, as numerous people on the freebsd-alpha list pointed out, the

Clean up (cough) residual handling. What we need for Fibre Channel

in the periph_priv field (layering violation)- but if an ATIO was
passed in from user land- forget it. This means that we'll probably
get residuals wrong for Fibre Channel commands we're completing
with an error. It's too late to 4.1 release to fix this- too bad.
Luckily the only device we'd really care about this occurring on

of being able to pair Qlogic generated ATIOs with CAM ATIOs, and then
to pair CAM CTIOs with Qlogic CTIOs, we have to take the CTIO passed
to us from XPT, and if it implies that we have to generate extra
Qlogic CTIOs, so be it. This means that we have to wait until the
last CTIO in a sequence we generated completes before calling xpt_done.
