15c37be013 If the timeout handler runs and notices that commands are timed out, check
the firmware status register on the card to see if the firmware is still
running.  There is no way to recover from this, but at least it can give
a hint as whether the car has crashed (which happens all too often).

03b5fe51bf Collapse sync fib locking into normal i/o locking. The former didn't
protect the registers so it was trivially possible for a sync command and
i/o command to fight each other and confuse the controller.  Make the
sync fib alloc/release functions inline and remove the somewhat worthless
AAC_SYNC_LOCK_FORCE flag.  Thanks to Adil Katchi for helping me to track
this down in RELENG_4.

397fa34f51 Collapse aac_map_command() into aac_startio(). Check the AAC_QUEUE_FRZN in
every iteration of aac_startio().  This ensures that a command that is
deferred for lack of resources doesn't immediately get retried in the
aac_startio() loop.  This avoids an almost certain livelock.

0b7ed341e1 Change the disk(9) API in order to make device removal more robust.
Previously the "struct disk" were owned by the device driver and this
gave us problems when the device disappared and the users of that device
were not immediately disappearing.

Now the struct disk is allocate with a new call, disk_alloc() and owned
by geom_disk and just abandonned by the device driver when disk_create()
is called.

Unfortunately, this results in a ton of "s/\./->/" changes to device
drivers.

Since I'm doing the sweep anyway, a couple of other API improvements
have been carried out at the same time:

The Giant awareness flag has been flipped from DISKFLAG_NOGIANT to
DISKFLAG_NEEDSGIANT

A version number have been added to disk_create() so that we can detect,
report and ignore binary drivers with old ABI in the future.

Manual page update to follow shortly.

4102d44b77 If a command has to be deferred because there are no more resources for it
on the card, unmap it first.  This allows it to be picked up properly when
the queue gets kicked again.  This was the root problem for the lost command
(i.e. stuck in getblk/vinvalb) problem.  While here, panic if commands don't
map correctly instead of just silently ignoring the problem and dropping
command.  Also slow down the dynamic allocation of new commands.

It should be safe to go back into the aac waters.  Thanks to everyone who
suffered through this and provided good feedback.

8f6a5435e7 Reduce AAC_MAX_FIBS to work around some yet-unidentified bugs in the
handling of resources shortages.  The driver is now so fast that it can
completely fill all 512 slots on the card, but for some reason only 511
slots are being allocated.  Anything that tries to go into the 512th
slot gets silently lost.   Both bugs need to be fixed at a later date,
but this should fix the reports of hangs in getblk and vinvalb.

a32a982d4a - Broaden the scope of locking in aac_command_thread() again to catch some
edge cases in the loop.

- Try to grab a command before dequeueing the bio from the bioq.  The old
  behaviour of requeuing deferred bios to the end of the bioq is arguably
  wrong.  This should be fixed in the future to check the bioq head without
  automatically dequeueing the bio.

9148fa21dd Take the plunge and make this driver be INTR_FAST. This re-arranges the
interrupt handler so that no locks are needed, and schedules the
command completion routine with a taskqueue_fast.  This also corrects the
locking in the command thread and removes the need for operation flags.

Simple load tests show that this is now considerably faster than FreeBSD 4.x
in the SMP case when multiple i/o tasks are running.

512824f8f7 - Implement selwakeuppri() which allows raising the priority of a
thread being waken up.  The thread waken up can run at a priority as
  high as after tsleep().

- Replace selwakeup()s with selwakeuppri()s and pass appropriate
  priorities.

- Add cv_broadcastpri() which raises the priority of the broadcast
  threads.  Used by selwakeuppri() if collision occurs.

7753acd255 Correctly wrap the producer queue index when dequeuing commands. This wasn't
a problem for command responses since we rarely ever filled the queue.
However, adapter-initiated commands have a much smaller queue and could
tickle this bug.  It's possible that this might fix the recently reported
problems with the aac-2120s, though I haven't been able to reproduce the
problem locally.
