DM9100/DM9102 chips. Do not set DC_TX_ONE. The DC_TX_USE_TX_INTR flag
causes dc_encap() to set the 'interrupt on TX completion' bit only
once every 64 packets. This is an attempt to reduce the number
of interrupts generated by the chip. You're supposed to get a 'no more
TX buffers left' interrupt once you hit the last packet whether you
ask for one or not, however it seems the Davicom chip doesn't generate
this interrupt, or at least it doesn't generate it under the same
circumstances. The result is that if you transmit n packets, where
n is less than 64, and then wait 5 seconds, you'll get a watchdog
timeout whether you want one or not. The DC_TX_INTR_ALWAYS causes
dc_encap() to request an interrupt for every frame.
I'm still waiting on confirmation from a couple of users to see if this
fixes their problems with the Davicom DM9102 before I merge this into
-stable, but this fixed the problem for me in my own testing so I'm
willing to make the change to -current right away.
- Layout reorganisation to enhance portability. The driver now has
a relatively MI 'core' and a FreeBSD-specific layer over the top.
Since the NetBSD people have already done their own port, this is
largely just to help me with the BSD/OS port.
- Request ID allocation changed to improve performance (I'd been
considering switching to this approach after having failed to come
up with a better way to dynamically allocate request IDs, and seeing
Andy Doran use it in the NetBSD port of the driver convinced me
that I was wasting my time doing it any other way). Now we just
allocate all the requests up front.
- Maximum request count bumped back to 255 after characterisation
of a firmware issue (off-by-one causing it to crash with 256
outstanding commands).
- Control interface implemented. This allows 3ware's '3dm' utility to
talk to the controller. 3dm will be available from 3ware shortly.
- Controller soft-reset feature added; if the controller signals a
firmware or protocol error, the controller will be reset and all
outstanding commands will be retried.
type of software interrupt. Roughly, what used to be a bit in spending
now maps to a swi thread. Each thread can have multiple handlers, just
like a hardware interrupt thread.
- Instead of using a bitmask of pending interrupts, we schedule the specific
software interrupt thread to run, so spending, NSWI, and the shandlers
array are no longer needed. We can now have an arbitrary number of
software interrupt threads. When you register a software interrupt
thread via sinthand_add(), you get back a struct intrhand that you pass
to sched_swi() when you wish to schedule your swi thread to run.
- Convert the name of 'struct intrec' to 'struct intrhand' as it is a bit
more intuitive. Also, prefix all the members of struct intrhand with
'ih_'.
- Make swi_net() a MI function since there is now no point in it being
MD.

past we stored this data in the CCB and attained the CCB via a pointer
in the SCB. In ahc_timeout(), however, the timedout SCB may have already
been completed (inherent race), meaning that the CCB could have been recycled,
and the ahc pointer reset.
Clean up the logic in ahc_search_qinfifo that deals with the busy device
table. For some reason it assumed that the only valid time to search
to see if additional lun entries should be checked was if lun 0 matched.
Now we properly itterate through the necessary luns. The busy device
table is used to detect invalid reselections, so a device would have had
to perform an unexpected reselection for this to cause problems. Further,
all luns are collapsed to a single entry unless we have external ram
with large SCBs (3940AU models) so the chance of this happening was
rather remote.
Clean up the logic for dealing with the untagged queues. We now set a
flag in the SCB that indicates that it is on the untagged queue instead
of inferring this from the type and setup of the CCB pased into us by
CAM.
In ahc_timeout(), don't print the path of the SCB until the controller
is paused and we are sure that it has not completed yet. This, in
conjunction with referencing the ahc pointer in the SCB rather than
the CCB in the SCB avoids panics in the case of a timedout scb completing
just before the timeout handler runs. This turns out to be guaranteed
if interrupt delivery is failing, as we run our interrupt handler to
flush any "just missed events" when a timeout occurs. Mention the
likelyhood of broken interrupts if a timedout SCB is completed by
our call to ahc_intr().

In target mode, reset the TQINPOS on every restart of the sequencer.
In the past we did this only during a bus reset, but there are other

In ahc_clear_critical_section(), disable pausing chip interrupts while
we step the sequencer out of a critical section. This avoids the
possibility of getting a pausing interrupt (unexpected bus free,
bus reset, etc.) that would prevent the sequencer from stepping.

aic7xxx_freebsd.c:
Go through the host message loop instead of issuing a single
byte message directly in the ahc_timeout() case where we
are currently on the bus to the device. The effect is the same,
but this way we get a nice printf saying that an expected BDR
was delivered instead of an unexpected bus free.
If we are requeuing an SCB for an error recovery action, be sure
to set the DISCONNECTED flag in the in-core version of the SCB.
This ensures that, in the SCB-paging case, the sequencer will
still recognize the reselection as valid even if the version
of the SCB with this flag set was never previously paged out
to system memory. In the non-paging case, set the MK_MESSAGE
flag in SCB_CONTROL directly.
