318e6bc3a5 Make the bus_dma_tag_create use NULL for the lock arguments. We are
careful to call all map_load calls with BUS_DMA_NOWAIT because we
really don't want some PDUs to wait while others go out - ATM guarantees
the ordering of cells and also of PDUs (within one VC, that is). With
BUS_DMA_NOWAIT bus_dmamap_load should never return EINPROGRESS.

Make the tag used for transmission buffers one larger than the maximum
AAL5 PDU (65535). This is needed, because all PDU sizes need to be round
up to multiple of four for the card and PDUs that are just below the
maximum size will be rounded up to 65536

e158f2b820 Update the SATA support code to work more correctly with
real SATA disks now that I can test it.

Add support for the SiI 3112 SATA chip using memory mapped I/O.
Update the support for the SiI 0680 to use the memio interface as well.

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.

3920999db7 Add a new PCI interface method, assign_interrupt, to determine the
interrupt to be used for a device. This is intended solely for internal
use of PCI bus implementations, and exists so that PCI bus drivers
implementing special interrupt assignment methods which require
additional work at the bus level to work right can be easily derived
from the generic driver (or any other one) without resorting to hacks.

It will be used in the sparc64 ofw_pcibus driver, which will be
committed shortly.

Make use of this method in the generic implementation, and add it to
the method table of bus drivers derived from the PCI one.

dcc9985adf Fix a race condition in the flushing of commands that
have completed across the bus but not to the host before
processing of an exception condition (busfree, bus reset,
etc.).  When flushing the controller of completed commands,
we also look for packetized commands that have completed
with good status and are stored in the "good status fifo".
The hardware will post to the good status fifo even if
data for that command is still active in a FIFO.  In
one particular failure case, a command outstanding on the
bus reconnected, transferred data into a FIFO, and provided
good status while the host driver was processing an expected
busfree event (PPR message negotiation).  This resulted in
an entry in the good status fifo that we completed, but
since the sequencer was paused, the data in the data FIFO
for this command had never been transferred to the host.
Once the busfree processing was complete, the sequencer
was unpaused, and the data completed its transfer to the
host.  In some instances, the client for the data was notified
of the completion and attempted to view the data before
it arrived.  This case only occurred during FreeBSD's
multi-target probe of the SCSI bus while some devices are
negotiating to go packetized and some devices are already
running in packetized.

The fix is to run and FIFOs active with a context in the
good status fifo to completion before completing the command
to the SCSI layer.  This requies duplicating the FIFO rundown
operations in the host driver that would usually be handled
by the firmware, but there is no other alternative.

Don't blindly shutdown the SCB dma engine when restarting
the sequencer.  We may be killing an operation that is
not supposed to be cancelled.  The cases where we need to
shutdown these dma engines are already handled elsewhere in
the driver.

Fix a few more ahd_in?() -> ahd_in?_scbram() instances.

b598de8f92 Correct a typo in a comment.
Add a comment in ahd_clear_critical_sections() about
our need to leave ENBUSFREE set in SIMODE1 while single
stepping.

Re-arrange some delay loops so that we always perform
a read after any register write and before the delay.
This should make the delay loop more accurate.

When completing message processing for a packetized
commention, return the controller to a state where
invalid non-packetized phases will still cause protocol
violations.  These are the same operations as those
performed in the clear_target_state routine in the
firmware.

Now that we have a chip with working ABORTPENDING
support (the 7901B), comment out the automatic use
of this feature until we can adequately test it.
The previous checkin updated the bug mask for the
7901B so this code was exercised.

When resetting the bus, perform an ahd_flush_device_writes()
call so that our reset assertion delay is acurately
timed from when the reset bit is written to the controller.

60c64b939b Remove check to see if the get resource for the second resource
succeeds.  There is a difference between how OLDCARD and NEWCARD deal
with their resources, and this code exposes that difference.  I'm not
sure which behavior is correct, and will need to look into that in
more detail.  However, it appears that we go ahead and allocate the
right thing in both cases that I have access to (CF cards, CDROM, and
external ata enclosures), so go ahead and ignore the failure to get
the resource for the other rid.  There's already another check to make
sure that the actual allocation works correctly, and that should be
sufficient to catch cases that don't work.

o fix wi_scan_ap to take a channel mask and txrate (for prism cards)

These changes fix dstumbler -o (monitor mode).  A minor change to dstumbler
is needed to get normal AP scanning mode to work right; this is preferred to

c7d24cc1a2 Fix a race condition that was introduced since pccbb interrupts are
flag'ed INTR_MPSAFE.  In ep_if_start(), use the IF_DEQUEUE macro to
grab the next mbuf to send, and use IF_PREPEND if the card is busy
and we actually can't handle it right now.

The old code was first getting the mbuf by taking it from the queue
without using the macros, thus without locking, and without removing
it from the queue either.  It was later assuming that IF_DEQUEUE would
give him this same mbuf.
