b9f0e11d4a Changed the first (name) arg of MOD_DEV(), MOD_EXEC() and MOD_MISC()
from a string to an identifier so that it can be used to generate
declarations and strings.  It's much easier to stringize an identifier
than to identifize a string.  A uniform naming scheme must be used
for the automatically generated things to apply.  This is a feature.

Used the module identifer to generate prototypes for the module load,
unload and stat functions.  Removed the few prototypes for these that
already existed.

Used the module identifier to generate a unique struct tag in MOD_DEV().
This should probably be done for all the MOD_*() macros.

Moved the trailing semicolon from the MOD_*() macro definitions to the
macro invocations that didn't already (bogusly) have it.

Staticized the module load and unload functions.

Added function return types for the module load, unload and stat functions.

lkm/ibcs2/ibcs2.c:
Included <sys/sysproto.h> to get everything prototyped.
Cleaned up #includes.

lkm/ibcs2/ipfw.c:
Cleaned up #includes.

lkm/linux/linux.c:
The module name had to change from "linux_emulator" to "linux_mod" to
be automatically generated.
Cleaned up #includes.

lkm/syscons/*/*_saver.c:
Completed delcarations of function pointers.

sys/i386/isa/atapi.c:
The module name had to change from "atapi" to "atapi_mod" to be
automatically generated.

sys/i386/isa/wcd.c:
Used the fixed MOD_DEV().  This module has two devices and expanded the
macro in the source instead of fixing it.
The module names had to change from "wcd" and "rwcd" to "wcd_mod" and
"rwcd_mod" to be automatically generated.

sys/pccard/pcic.c:
The module name had to change from "pcic" to "pcic_mod" to be
automatically generated.

4d0291b75b Replaced nosys() by lkm_nullcmd(). Always call lkm load/unload/stat
functions instead of skipping the call if the function is nosys().
nosys() returned the wrong value as well as having the wrong type.

da1c8c00f7 This is a totally new implementation of eisaconf. It will hopefully
be the beginning of our move to a more dynamic (configuration manager)
based setup for all drivers.  Everything seems to work except for
some devconf problems.  Only the aic7xxx driver will be using this
interface until it is reviewed, revised and accepted as a good configuration
interface.

Adapt aic7770.c to use new eisaconf.

eisadevs.c is replaced by a linker set.

6073486300 Added `#include "ioconf.h"' to <machine/conf.h> and cleaned up the
misplaced extern declarations (mostly prototypes of interrupt handlers)
that this exposed.  The prototypes should be moved back to the driver
sources when the functions are staticalized.

Added idempotency guards to <machine/conf.h>.  "ioconf.h" can't be
included when building LKMs so define a wart in bsd.kmod.mk to help
guard against including it.

cb39a8365e Do a pass over the broken LKM's and update them to use the "new"
convention of having their entry point named "<modname>_mod"".
Symorder is enforcing this when the current bsd.kmod.mk is installed.

I've not tested all these, but at least they all compile now.

Reattach them to the makefile.

Note that the change that I made to symorder needs to be compiled and
installed before any LKM's will work - the last version was corrupting
the relocation tables.  A "make world" will to this, but if you
manually run a make on the lkm's you'll need to take care of it by
hand.

52751dc395 Set SCSIGO generically before we determine the phase instead of doing it
in each phase routine.  Saves a few instructions.

Be more careful in how we deal with SXFRCTL0.  Or in the control bits of
interest instead of using mvi.  The kernel driver will set the ULTRAEN
bit of SXFRCTL0 if we are using Ultra (20MHz) mode and we don't want to
clobber it.

In sdtr_to_rate divide by two if we are in ultra mode to get the correct
setting since its a 20MHz instead of 10MHz scale.

2b02753359 sio.c:
Fix the tests for being a console by reverting to the ones that
were used before the the RB_SERIAL changes.  RB_SERIAL only needs
to be tested in one place.  The initialization of comconsole was
wrong before the RB_SERIAL changes for the COMCONSOLE case.  This
may have been the cause of the unnecessary changes.

Start eliminating #includes of <i386/i386/cons.h>.  This header is
supposed to be included from <machine> although it should be
completely machine-independent and included from <sys>.

Remove a wrong XXX comment.  `comconsole' is used to test for being
a console and even the tests for deciding the default termios state
are necessary (the semi-reentrant i/o routines don't handle ordinary
device i/o).

cy.c:

95dd59f2ae 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!

f24102e640 Fixed a problem that malloc(..,..,M_NOWAIT) was being called without checking
for return values.  It just so happens that in the cases where it is likely
to fail, it is okay to change the M_NOWAIT to M_WAITOK -- and all will
be well.  This problem was manfest as a panic very regularly on a 4MB
system right after bootup.

685c99c94e Total rewrite of the dataphase sections of the sequencer. This was done
to replace the very poor, original implementation of Scatter/Gather operations.

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.

This commit drops the sequencer from 426 instructions to 390 most likely
freeing enough space to do a target mode implementation.

1df678461b 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.

17d6fa2126 Sleep on a better address to wait for output to drain out of the
hardware.  Set the sleep-on flag for the address so there is more
than a small chance that the sleep address is actually used (this
used to work by timing out).  Don't bother clearing the sleep-on
flag after a timeout here or elsewhere since leaving it set just
generates a few null calls to wakeup().

6161be8527 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.

Optimize the other selwakeup() call (this is not related to the other
changes).

kern/tty_pty.c:
ptcopen() can be declared in traditional C now that dev_t isn't short.

105a5302c8 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.

688f94b143 Move the inline code for waking up writers to a new function
ttwwakeup().  The conditions for doing the wakeup will soon become
more complicated and I don't want them duplicated in all drivers.

It's probably not worth making ttwwakeup() a macro or an inline
function.  The cost of the function call is relatively small when
there is a process to wake up.  There is usually a process to wake
up for large writes and the system call overhead dwarfs the function
call overhead for small writes.

e97bb42ff7 Fix races in scstart(). q_to_b() wasn't called at spltty(), so there
were two races:
- q_to_b() might unexpectedly return 0 (e.g, after a keyboard signal
  flushes the output queue and isn't echoed).  ansi_put() interprets
  0 bytes as 4GB...
- more output (e.g. for echoes) might arrive afer q_to_b() returns 0.
  Then scstart() returns presumably and the new output might not be
  handled for a long time.
