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

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

f6b1c44d1f Mega busdma API commit.
Add two new arguments to bus_dma_tag_create(): lockfunc and lockfuncarg.
Lockfunc allows a driver to provide a function for managing its locking
semantics while using busdma.  At the moment, this is used for the
asynchronous busdma_swi and callback mechanism.  Two lockfunc implementations
are provided: busdma_lock_mutex() performs standard mutex operations on the
mutex that is specified from lockfuncarg.  dftl_lock() is a panic
implementation and is defaulted to when NULL, NULL are passed to
bus_dma_tag_create().  The only time that NULL, NULL should ever be used is
when the driver ensures that bus_dmamap_load() will not be deferred.
Drivers that do not provide their own locking can pass
busdma_lock_mutex,&Giant args in order to preserve the former behaviour.

sparc64 and powerpc do not provide real busdma_swi functions, so this is
largely a noop on those platforms.  The busdma_swi on is64 is not properly
locked yet, so warnings will be emitted on this platform when busdma
callback deferrals happen.

If anyone gets panics or warnings from dflt_lock() being called, please
let me know right away.

ae54359608 Bring aac out from under Giant:
- the mutex aac_io_lock protects the main codepaths which handle queues and
  hardware registers.  Only one acquire/release is done in the top-half and
  the taskqueue.  This mutex also applies to the userland command path and
  CAM data path.
- Move the taskqueue to the new Giant-free version.
- Register the disk device with DISKFLAG_NOGIANT so the top-half processing
  runs without Giant.
- Move the dynamic command allocator to the worker thread to avoid locking
  issues with bus_dmamem_alloc().

This gives about 20% improvement in most of my benchmarks.

8480cc638e o Move the cleanup of the fib maps into aac_free_commands() so as to
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
  architecture specific constant.

f30ac74cb0 Major bugfixes for large memory and fast systems.
aac.c:
        Re-arrange the interrupt handler to optimize the common case of
        the adapter interrupting us because one or more commands are complete,
        and do a read across the pci bus to ensure that all posted status
        writes are flushed.  This should close a race that could cause command
        completion interrupts to be lost.
        Follow the spec a bit closer when filling out command structures.
        Enable the Fast Response feature to eliminate the need for the card
        to DMA successfull command completions back into host memory.
        Tell the controller how much physical memory we have.  Without this
        there was a chance that our DMA regions would collide with the
        memory window used by the cache on the controller.  The result would
        be massive data corruption.  This seemed to mainly affect systems with
        >2GB of memory.
        Fix a few whitespace problems.

aac_debug.c:
        Add an extra diagnostic when printing out commands.

aac_disk.c:
        Add extra sanity checks.

aacreg.h:
        Prepare for making this 64-bit clean by reducing the use of enumeration
        types in structures.

7419815d60 The AAC_COMPAT_LINUX option was really annoying, since it made the

compat bits for this driver are now in their own driver, aac_linux.
It can be loaded as a module or compiled into the kernel.  For
the latter case, the AAC_COMPAT_LINUX option is needed, along with
the COMPAT_LINUX option.

7812d86f03 (This commit touches about 15 disk device drivers in a very consistent
and predictable way, and I apologize if I have gotten it wrong anywhere,
getting prior review on a patch like this is not feasible, considering
the number of people involved and hardware availability etc.)

If struct disklabel is the messenger: kill the messenger.

Inside struct disk we had a struct disklabel which disk drivers used to
communicate certain metrics to the disklayer above (GEOM or the disk
mini-layer).  This commit changes this communication to use four
explicit fields instead.

Amongst the benefits is that the fields do not get overwritten by
wrong or bogus on-disk disklabels.

Once that is clear, <sys/disk.h> which is included in the drivers
no longer need to pull <sys/disklabel.h> and <sys/diskslice.h> in,
the few places that needs them, have gotten explicit #includes for
them.

The disklabel inside struct disk is now only for internal use in
the disk mini-layer, so instead of embedding it, we malloc it as
we need it.

This concludes (modulus any mistakes) the series of disklabel related
commits.

I belive it all amounts to a NOP for all the rest of you :-)

fe3cb0e1ec Add a CAM interface to the aac driver. This is useful in case you should
ever connect a SCSI Cdrom/Tape/Jukebox/Scanner/Printer/kitty-litter-scooper
to your high-end RAID controller.  The interface to the arrays is still
via the block interface; this merely provides a way to circumvent the
RAID functionality and access the SCSI buses directly.  Note that for
somewhat obvious reasons, hard drives are not exposed to the da driver
through this interface, though you can still talk to them via the pass
driver.  Be the first on your block to low-level format unsuspecting
drives that are part of an array!

To enable this, add the 'aacp' device to your kernel config.

426da3bcfb SMP Lock struct file, filedesc and the global file list.
Seigo Tanimura (tanimura) posted the initial delta.

I've polished it quite a bit reducing the need for locking and
adapting it for KSE.

Locks:

1 mutex in each filedesc
   protects all the fields.
   protects "struct file" initialization, while a struct file
     is being changed from &badfileops -> &pipeops or something
     the filedesc should be locked.

1 mutex in each struct file
   protects the refcount fields.
   doesn't protect anything else.
   the flags used for garbage collection have been moved to
     f_gcflag which was the FILLER short, this doesn't need
     locking because the garbage collection is a single threaded
     container.
  could likely be made to use a pool mutex.

1 sx lock for the global filelist.

struct file *	fhold(struct file *fp);
        /* increments reference count on a file */

struct file *	fhold_locked(struct file *fp);
        /* like fhold but expects file to locked */

struct file *	ffind_hold(struct thread *, int fd);
        /* finds the struct file in thread, adds one reference and
                returns it unlocked */

struct file *	ffind_lock(struct thread *, int fd);
        /* ffind_hold, but returns file locked */

I still have to smp-safe the fget cruft, I'll get to that asap.

0b94a66e3f Major bugfix and minor update. This should resolve the current issues
with the driver locking up under load.

 - Restructure so that we use a static pool of commands/FIBs, rather than
   allocating them in clusters.  The cluster allocation just made things
   more complicated, and allowed us to waste more memory in peak load
   situations.
 - Make queueing macros more like my other drivers.  This adds queue stats
   for free.  Add some debugging to take advantage of this.
 - Reimplement the periodic timeout scan.  Kick the interrupt handler
   and the start routine every scan as well, just to be safe.  Track busy
   commands properly.
 - Bring resource cleanup into line with resource allocation.  We should
   now clean up correctly after a failed probe/unload/etc.
 - Try to start new commands when old ones are completed.  We weren't doing
   this before, which could lead to deadlock when the controller was full.
 - Don't try to build a new command if we have found a deferred command.
   This could cause us to lose the deferred command.
 - Use diskerr() to report I/O errors.
 - Don't bail if the AdapterInfo structure is the wrong size.  Some variation
   seems to be normal.  We need to improve our handing of 2.x firmware sets.
 - Improve some comments in an attempt to try to make things clearer.
 - Restructure to avoid some warnings.
