kernel. Justin agress that there is no other reasonable alternative to
do automatic rescans on connect.
The problem is that when a new device attaches to a SIM (SCSI host
controller) we need to send a XPT_SCAN_BUS command to the SIM using
xpt_action. This requires however that there is a peripheral available
to take the command (otherwise xpt_done and later bomb). The RESCAN
ioctl uses the same periph.
This enables a USB mass storage drive to do an automatic rescan on
connection of the drive.
The automatic dropping of a CAM entry on disconnection was already
working (asynchronous event).
The next thing to do is find someone to commit a change to vpo to do the
same thing. Just port umass_cam_rescan and friends across to that
driver.

the corresponding "buf" versions will disappear when no longer used.
Move b_offset, b_data and b_bcount to struct bio.
Add BIO_FORMAT as a hack for fd.c etc.
We are now largely ready to start converting drivers to use struct
bio instead of struct buf.
unit numbers all wrong. This did not show up because most of them where
zero anyway.
Use a separate buffer for command transforms instead of fiddling with
the existing cdb_bytes.
Take CAM_CDB_POINTER into account. Nobody is using it, but someone might
in the future.
Be more picky about what to accept in the UFI command set.
First attempt at implementing the ATAPI command protocol transforms.
This should at least make Imation Superdisk and other e-Shuttle based
devices show as attached. Maybe they even work to some extent.
(Much of this done by script)
Move B_ORDERED flag to b_ioflags and call it BIO_ORDERED.
Move b_pblkno and b_iodone_chain to struct bio while we transition, they
will be obsoleted once bio structs chain/stack.
Add bio_queue field for struct bio aware disksort.

introduced in FreeBSD-4.0. The driver is now full up-to-date
with regards to the current kernel interfaces.
Another significant change in this driver version applies
to the checking of the data direction. The driver is now
able to check against the expected data direction in any
circumstance and will not hang either if direction is wrong
at the start of the IO, or if for some weird reason,
the device changes to the wrong direction during the IO.
This driver version is still usable under FreeBSD 3.2/3.3,
since it only requires CAM, other kernel interface dependencies
being #if'ed in the sources according to kernel version.
But, in order to use the driver under those early kernel
versions, user has to move the driver sources by hand and make
appropriate tiny changes to let the kernel know about the driver.
Other changes:
- Remove the debugging stuff for WSR bit.
- Get rid of some warnings about volatile being discarded.
which think they know the IntelliMouse 4-byte packet and believe,
wrongly, that any other protocols use 3-byte packets.
- Update a couple of comment lines for A4 Tech mice.
- Mike Smith discovered a panic in the changer probe code if the probe
command (mode sense) fails. So we need to release the CCB used in the
probe before we unlock the peripheral. (i.e. the same fix mjacob put in
the CD and DA drivers)

your feet. The conversion of the "snp" device to a dynamically growing
device driver was done just a few days ago by Brooks Davis! Shame on
me for not finding that PR :(
This is a forced commit of tty_snoop.c to give the submitter proper credit,
as most of the patch submitted is actually exactly the same code (by some
large amount of entropy). Brooks also submitted the change to LINT to
set the example of "snp" usage to not include a number, as that number is
now deprecated, so that is also in this commit.

async I/O's. The sequential read heuristic has been extended to
cover writes as well. We continue to call cluster_write() normally,
thus blocks in the file will still be reallocated for large (but still
random) I/O's, but I/O will only be initiated for truely sequential
writes.
This solves a number of annoying situations, especially with DBM (hash
method) writes, and also has the side effect of fixing a number of
(stupid) benchmarks.

Add some new commands states; WEDGED (never coming back) and

- Remove a number of redundant efforts to poll the card for completed
commands. This is what interrupt handlers are for.
- Limit the maximum number of outstanding I/O transactions. It seems
that some controllers report more than they can really handle,
and exceding this limit can cause the controller to lock up.
- Don't use 'wait' mode for anything where the controller might not
be able to generate interrupts. (Keep the 'wait' mode though sa it
will become useful when we start taking userspace commands.
- Use a similar atomic locking trategy to the Mylex driver to prevent
some reentrancy problems.
- Correctly calculate the block count for non-whoile-bloch transfers
(actually illegal).
- Use the dsik device's si_drv1 field instead of b_driver1 in the
buf struct to pass the driver identifier arond.
- Rewrite amr_start and amr_done() along the lines of the Mylex driver
in order to improve robustnes.
- Always force the PCI busmaster bit on.
