non-device code.
* Re-implement the method dispatch to improve efficiency. The new system
takes about 40ns for a method dispatch on a 300Mhz PII which is only
10ns slower than a direct function call on the same hardware.
This changes the new-bus ABI slightly so make sure you re-compile any
driver modules which you use.
- Add support for ISA based DPT adapters (this doesn't quite work yet).
- Sync dpt_eisa.c with my local copy.
- Simplify how EISA IDs are matched.
- Prototype.
- Formatting nits.
- Conform to how I do things in dpt_pci.c/dpt_isa.c.
- Modify dpt_scsi.c:dpt_alloc() to DTRT with newbus.
- Add some comments to dpt_scsi.c:dpt_pio_get_conf().
- Add additional check to dpt_scsi.c:dpt_get_conf().
- Add some useful error messages to dpt_scsi.c:dpt_init().
request could be deallocated before the top half had finished
issuing it. The problem seems only to happen with IDE drives
and vn devices, but theoretically it could happen with any
drive. This is the most important part of a possible series
of fixes designed to remove race conditions without locking
out interrupts for longer than absolutely necessary.

Pass sc->dev rather than a bogusly cast pccard_softc *sc.
This allows us to insert and remove cards w/o panicing the kernel.
However, the cis isn't mapped in, so the pccard_scan_cis function
fails.
- Request the maximum number of LUNs on a device if it is
a Bulk-Only device.
- Handle NO_TEST_UNIT_READY case for SCSI
- Add NO_START_STOP quirk for LS-120
- Fix a KASSERT which was the wrong way around.
- Kickstart the LS-120 with the infamous LS-120 specific command of
which no one knows what it doesn, apart from the fact that it appeared

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.

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.

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

Add bio_queue field for struct bio aware disksort.
Address a lot of stylistic issues brought up by bde.

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.

i don't seem to be clearing the cache right resulting in a short initial
burst of noise, despite doing the same as creative and alsa. i'm committing
now so more eyes can pore over the code.

doesn't support winmodems, softmodems, hcf or any other modem that
relies on the host to do any sort of soft control for any aspect of
the modem's function. There are two modems known to work:
3COM FaxModem PCI.
ActionTec 56k VoiceMessaging PCI Modem
and the following modem might work
Multitech PCI FaxModem (not sure about this)
and the serial pci cards might work too. I have neither these
hardware items so I can't add support for them.
- Add periodic status monitoring routine. Currently just detects
lost commands, further functionality pending data from AMI.
Add some new commands states; WEDGED (never coming back) and
LATE (for when a command that wasmarked as WEDGED comes bacj,
- 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.
