8af5d536ff devfs changes..
changes to allow devices that don't probe (e.g. /dev/mem)
to create devfs entries
this required giving 'configure' its own SYSINIT entry
so we could duck in just before it with a DEVFS init
and some device inits..
my devfs now looks like:
./misc
./misc/speaker
./misc/mem
./misc/kmem
./misc/null
./misc/zero
./misc/io
./misc/console
./misc/pcaudio
./misc/pcaudioctl
./disks

./disks/rfloppy/fd1.1200
./disks/floppy
./disks/floppy/fd0.1440
./disks/floppy/fd1.1200
also some sligt cleanups.. DEVFS needs a lot of work
but I'm getting back to it..

d1a599c2de Something got spammed in my 2.2 work tree (don't know how :( ) and
had a 2.1 tag, thus sending these two changes into the 2.1 branch instead

4bb0ce8ce3 Fix correct_writedisklabel() and writedisklabel(). Their setting of
bp->b_flags has been broken for many years:
a) they didn't set B_BUSY for doing i/o.  This has been fatal since
   1995/07/25 when biodone() started checking that B_BUSY is set.
b) they didn't set B_INVAL for releasing the buffer.  This at best
   just put a useless buffer in the LRU queue for a little while.

Fix a couple of spelling errors and complete a couple of function
pointer declarations.

2b14f991e6 Reviewed by: julian with quick glances by bruce and others
Submitted by:	terry (terry lambert)
This is  a composite of 3 patch sets submitted by terry.
they are:
New low-level init code that supports loadbal modules better
some cleanups in the namei code to help terry in 16-bit character support
some changes to the mount-root code to make it a little more
modular..

NOTE: mounting root off cdrom or NFS MIGHT be broken as I haven't been able
to test those cases..

certainly mounting root of disk still works just fine..
mfs should work but is untested. (tomorrows task)

The low level init stuff includes a total rewrite of init_main.c
to make it possible for new modules to have an init phase by simply
adding an entry to a TEXT_SET (or is it DATA_SET) list. thus a new module can
be added to the kernel without editing any other files other than the
'files' file.

07b1c6b3c9 Remove hard coded assumption that SCSI busses have 7 targets.
This change forces the controller drivers to allocate a scsibus_data struct
via a call to scsi_alloc_bus(), fill in the adapter_link field, and optionally
modify any other fields of the struct.  Scsi_alloc_bus() initializes all fields
to the default, so the changes in most drivers are very minimal.  For drivers
that support Wide controllers, the maxtarg field will have to be updated to
allow probing of all targets (for an example, look at the aic7xxx driver).

Scsi_attachdevs() now takes a scsibus_data* as its argument instead of an
sc_link*.  This allows us to expand the role of the scsibus_data struct for
other bus level configuration setings (max number of transactions, current
transaction opennings, etc for better tagged queuing support).

6adca7ad76 Fix some problems with multicast forwarding:
Garrett,

  Here are some patches for the rate limiting code.  It should be faster,
and in particular it doesn't leak malloc'd memory any more when rate_limit'ing
a phyint.

  It now uses an mbuf chain at each vif, instead of the static queue array.
This means that the MAXQSIZE is now variable per vif (although there is no
interface to change it other than a debugger); this is an area for more
experimentation.

Claim the major numbers (before sombedoy else jumps in again and

While i've been at this, i've cleaned up some of the routines at the
end of i386/conf.c; all the importers of the latest CDROM drivers
forgot to fill in the appropriate information.  The `ata' driver
(vapourware?) does only occupy a slot in the bdevsw[] array, btw.

The actual import of the code does require a minor change in the SCSI
subsystem, and i want to have this reviewed by Peter first, so it will
be deferred for some days.  The driver is already working for me
though.

b77990be3e Bring in my long-overdue version of the Specialix driver.
This was originally ported to BSDI by Andy Rutter <andy@acronym.co.uk>.
At the end of the day, this code has very little in common with Andy's
version, or the Specialix SYSV version.  Essentially it has been gradually
and almost completely rewritten, with LOTS of advice and inspiration from
Bruce Evans.  There are a couple of missing bits still, but they are minor.

The user-mode "sicontrol" program is in sad shape and will come in soon.
Transparent printing died a timely death.. Maybe later..

Jeremy Rolls @ Specialix (Development directory) has confirmed this is OK
to distribute, and Andy personally sent me his version that I started from.

Although this driver stood up to a nasty stress-test in this form, I am not
confident that there are no nasty bugs lurking.

People are welcome to try it, but dont go out and buy one just yet.. :-)
And *DONT* use it on a mission-critical machine... This is ALPHA QUALITY!

Use a bit (that was freed up with the rewrite above) in the SCB control byte
to designate commands that should allow disconnection.  The kernel driver
makes this decision now instead of the sequencer since the sequencer can't
do the indexing very efficiently.

116616a829 Fix two race conditions.
The first could occur because the original code would continue to reset
the SCSIID register while waiting for a selection.  This could potentially
conflict with a reconnect since a successfull reconnect will also set the
SCSIID register.  The fix is to use a separate wait loop after starting
a selection (as was done a few revisions ago).

The second probably never happens, but it was possible for a target to
reconnect while there was a pending SCB on the waiting list and not get
noticed.  The fix was to remove a supurflous check of the scb waiting
list.

9fa18570a2 Obtained from: partly from ancient patches of mine via 1.1.5
Introduce TS_CONNECTED and TS_ZOMBIE states.  TS_CONNECTED is set
while a connection is established.  It is set while (TS_CARR_ON or
CLOCAL is set) and TS_ZOMBIE is clear.  TS_ZOMBIE is set for on to
off transitions of TS_CARR_ON that occur when CLOCAL is clear and
is cleared for off to on transitions of CLOCAL.  I/o can only occur
while TS_CONNECTED is set.  TS_ZOMBIE prevents further i/o.

Split the input-event sleep address TSA_CARR_ON(tp) into TSA_CARR_ON(tp)
and TSA_HUP_OR_INPUT(tp).  The former address is now used only for
off to on carrier transitions and equivalent CLOCAL transitions.
The latter is used for all input events, all carrier transitions
and certain CLOCAL transitions.  There are some harmless extra
wakeups for rare connection- related events.  Previously there were
too many extra wakeups for non-rare input events.

Drivers now call l_modem() instead of setting TS_CARR_ON directly
to handle even the initial off to on transition of carrier.  They
should always have done this.  l_modem() now handles TS_CONNECTED
and TS_ZOMBIE as well as TS_CARR_ON.

gnu/isdn/iitty.c:
Set TS_CONNECTED for first open ourself to go with bogusly setting
CLOCAL.

i386/isa/syscons.c, i386/isa/pcvt/pcvt_drv.c:
We fake carrier, so don't also fake CLOCAL.

kern/tty.c:
Testing TS_CONNECTED instead of TS_CARR_ON fixes TIOCCONS forgetting to
test CLOCAL.  TS_ISOPEN was tested instead, but that broke when we disabled
the clearing of TS_ISOPEN for certain transitions of CLOCAL.

Testing TS_CONNECTED fixes ttyselect() returning false success for output
to devices in state !TS_CARR_ON && !CLOCAL.

changes).

f3b37f91c1 Improve input flow control.
Use input buffer watermarks of TTYHOG-512 (high) and (high)*7/8
(low) instead of TTYHOG/2 (high) and TTYHOG/5 (low) to agree with
some drivers.  512 is magic and some things depended on TTYHOG/2
>= TTYHOG-512 to work; now they depend on the 512 magic not changing
and TTYHOG-512 being significantly larger than 0.  This should be
handled in ttsetwater().

Separate the decision about whether to do input flow control from
doing it.  ttyblock() now just starts input flow control (hardware
and/or software) and there is a new function ttyunblock() to stop
it.  The decisions are the same except for the watermark changes
and allowing for input expansion for PARMRK.

When flushing input, try harder at first to send a start character
if required, but give up if the first attempt fails.

cy.c, rc.c, sio.c:
Simplify: let ttyinput() handle input flow control if it is not
being bypassed.  Use ttyblock() to start flow control otherwise.

rc.c:
Use same input flow control test as elsewhere: test in a more
efficient order and start flow control at >= highwater instead of
at > highwater.

  are no longer special cased in kernfs_lookup().

Note: procfs, fdescfs, and most of the other miscfs/* file systems
also suffer from the same type of problems and I will work on
fixing them one at a time.

185363acb2 Long overdue, more complete, reset code. These changes implement a
BUS DEVICE RESET followed by BUS RESET failure recovery strategy including
the necesary renegotiation of sync/wide transfers after recovery completes.

Clean up debugging code to make it more finely selectable.  Reset code
debugging is enabled for now so I can get more feedback on how this
code behaves in real life.

70eec7420c Ignore trailing slashes in pathnames that "refer to a directory",
as is required to be POSIXLY_CORRECT and "right".  I interpret
"referring to a directory" as being a directory or becoming a
directory.  E.g., the trailing slashes in mkdir("/nonesuch/"),
rename("/tmp", /nonesuch/") and link("/tmp", "/root_can_like_dirs/")
are ignored because the target will become a directory if the
syscall succeeds.  A trailing slash on a symlink causes the symlink
to be followed (this is a bug if the symlink doesn't point to a
directory; fix later).

79ccb9aff3 Don't swap the queue headers to implement concatenation of the
queues for TIOCSETA[W].  Swapping an even number of times broke
the queue resource limits.  This would have broken CRTSCTS flow
control if the clist slush list was used up.

Don'concatenate the queues for TIOCSETA[W] if one of the queues
has a resource limit of 0.  Concatenation would cause a panic if
one of the queues is nonempty and the other is limited to length
0.  This may have caused panics in PPPDISC.

Wake up readers after all transitions of ICANON.  When ICANON is
turned off it is quite likely that characters will become available
to be read.

Reduce indentation near these changes.

d7515ab5cf Split TS_ASLEEP (sleep on output [below low water])into TS_SO_OLOWAT (sleep
on output below low water) and TS_SO_OCOMPLETE (sleep on output complete).
Most of the support for this has already been committed.  Drivers should
call ttwwakeup() to handle wakeups whenever output is below low water
(and some output event causes this condition to be checked) or TS_BUSY is
cleared.

tty.c:
Fix the livelock in ttywait() properly by sleeping on output complete, not
on output below low water.

Use ttwwakeup() instead of separate select and output wakeups for all
wakeups of writers.

Add wakeups of writers for output flushes and carrier/clocal transitions.

Don't go to sleep in ttycheckoutq() if ttstart() reduces the queue to below
low water.

Use the timeout built into tsleep() in ttycheckoutq().

Optimize the select wakeup in ttwwakeup().  It seems reasonable to know
too much about the internals of tp->t_wsel now that the knowledge is
localised in tty.c.

267513a942 Obtained from: partly from ancient patches by ache and me via 1.1.5
Remove nullmodem().

It may be useful to have a null modem routine, but nullmodem()
wasn't one.  nullmodem() was identical to ttymodem() except it
didn't implement MDMBUF (carrier) flow control, didn't do any
wakeups for off to on carrier transitions, and didn't flush the
i/o queues for on to off carrier transitions (flushing has the side
effect of waking up readers and writers) although it did generate
SIGHUPs.  The wakeups must normally be done even if nullmodem() is
null in case something is sleeping waiting for a carrier transition.
In any case, the wakeups should be harmless.  They may cause bogus
results for select(), but select() is already bogus for nonstandard
line disciplines.

Always (except in code to be replaced soon) call driver start
routine directly instead of going through ttstart().

how my integration of that was since I don't have this card to test.
I've only tested this on my GUS MAX since it's all I have.

This all probably needs to be re-done anyway since we're widely variant
from the original VOXWARE source in the current layout.

This finishes making the kernel compile without -O.

The "optimized" asm version of the function being inlined
(translate_bytes()) uses slow instructions.  On a 486, assuming
everything is in the cache (unlikely), it is 21/15 times slower
than the dumb C version and 21/3 times slower than the best
possible bytewise method.
