s/defininitions/definitions/
s/ininitialise/initialise/
s/collasped/collapsed/
s/optionaly/optionally/
 1.81  06-Jan-2023  tsutsui branches: 1.81.6;
TAB/spaces/indents cleanup.
 1.80  26-Jun-2022  tsutsui Make local devsw functions static.

No visible regression on TT030.
 1.79  03-Jan-2021  thorpej malloc(9) -> kmem(9)
 1.78  08-Feb-2018  dholland branches: 1.78.16;
Typos.
 1.77  25-Jul-2014  dholland Add d_discard to all struct cdevsw instances I could find.

All have been set to "nodiscard"; some should get a real implementation.
 1.76  24-Mar-2014  christos branches: 1.76.2;
- remove unused
- use cpu_{g,s}etmodel() (not committed yet)
 1.75  16-Mar-2014  dholland Change (mostly mechanically) every cdevsw/bdevsw I can find to use
designated initializers.

I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.
 1.74  30-Jun-2011  wiz branches: 1.74.2; 1.74.12; 1.74.16;
dependant -> dependent
 1.73  24-Apr-2011  rmind Rename ttymalloc() to tty_alloc(), and ttyfree() to tty_free() for
consistency. Remove some unnecessary malloc.h inclusions as well.
 1.72  09-Apr-2010  tsutsui branches: 1.72.2;
- establish zs interrupts via common intr_establish() function rather than
hardcording them in locore.s and vector.s
- also make interrupt handlers take per unit softc and put a softint cookie
into softc (though atari machines have only one zs)
- tweak some structures as per MI z8530sc driver

Tested on TT030 using sl(4) on zs.
 1.71  09-Apr-2010  tsutsui minor constify
 1.70  09-Apr-2010  tsutsui More KNF.
 1.69  09-Apr-2010  tsutsui Split device_t/softc.
 1.68  09-Apr-2010  tsutsui Rename variables and members of softc for readability.
 1.67  09-Apr-2010  tsutsui Remove unnecessary volatile keyword against struct zschan.
(volatile against structure member is enough)
 1.66  09-Apr-2010  tsutsui - misc KNF
- remove `register' keyword from variable declarations
 1.65  09-Apr-2010  tsutsui Include ioconf.h for struct cfdriver.
 1.64  19-Jul-2009  tsutsui branches: 1.64.2; 1.64.4;
Replace one missed bcopy(9) with memcpy(9).
 1.63  19-Jul-2009  tsutsui Remove extra whitespace added by a dumb tool which replaced bcopy with memcpy.
 1.62  18-Mar-2009  cegger bcopy -> memcpy
 1.61  14-Mar-2009  dsl ANSIfy another 1261 function definitions.
The only ones left in sys are beyond by sed script!
(or in sys/dist or sys/external)
Mostly they have function pointer parameters.
 1.60  14-Mar-2009  dsl Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)
 1.59  14-Mar-2009  dsl Remove all the __P() from sys (excluding sys/dist)
Diff checked with grep and MK1 eyeball.
i386 and amd64 GENERIC and sys still build.
 1.58  28-Jan-2009  tjam branches: 1.58.2;
Remove sicallback to use the MI softint(9) APIs directly - from Tsutsui
 1.57  11-Jun-2008  tsutsui branches: 1.57.4; 1.57.6;
Use device_private() and device_lookup_privat() to get softc.
 1.56  29-Apr-2008  martin branches: 1.56.2; 1.56.4;
Convert to new 2 clause license
 1.55  08-Jan-2008  joerg branches: 1.55.6; 1.55.8; 1.55.10;
Convert Atari to generic TODR and timecounter.

- Fix another tty signalling/wakeup problem.
 1.53  06-Mar-2007  tsutsui branches: 1.53.2; 1.53.18; 1.53.20; 1.53.24; 1.53.26;
Make TX buffer (uint8_t *) and remove an unnecessary cast.
 1.52  04-Mar-2007  christos Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
 1.51  01-Oct-2006  elad branches: 1.51.4;
More from Matt Fleming:

Adapt to KAUTH_DEVICE_TTY_PRIVSET and KAUTH_DEVICE_TTY_OPEN.
 1.50  01-Oct-2006  elad Adapt MD code to KAUTH_DEVICE_TTY_OPEN. Patch from Matt Fleming, thanks!
 1.49  04-Aug-2006  mhitch branches: 1.49.4; 1.49.6;

Add a space between numbers and Hz unit.
 1.45  11-Dec-2005  christos branches: 1.45.4; 1.45.6; 1.45.8; 1.45.10;
merge ktrace-lwp.
 1.44  06-Sep-2005  kleink Change the driver open function's conditional for overriding exclusive tty
use from checking the proc's uid to suser(9), and account for the use of
privileges. Noted by David Holland in PR kern/31126.
 1.43  04-Jun-2005  he branches: 1.43.2;
Adapt to compiling with -Wshadow and -Wcast-qual, by adding const
qualification in places and renaming a few local variables.
Also adds a couple uses of __UNVOLATILE() to allow passing volatile
variables to functions wanting e.g. caddr_t.
 1.42  25-Mar-2004  leo Licence cleanup (suggested by wiz).
 1.41  07-Aug-2003  agc Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22364, verified by myself.
 1.40  15-Jul-2003  lukem __KERNEL_RCSID()
 1.39  23-Oct-2002  jdolecek branches: 1.39.6;
merge kqueue branch into -current

kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals

kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)

based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe
 1.38  02-Oct-2002  thorpej Use CFATTACH_DECL().
 1.37  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.36  06-Sep-2002  gehenna Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.
 1.35  17-Mar-2002  atatat branches: 1.35.4;
Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for
indicating an unhandled "command". ERESTART is -1, which can lead to
confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4. No ioctl code should now return -1 anywhere. The
ioctl() system call is now properly restartable.
 1.34  02-May-2001  scw branches: 1.34.2; 1.34.4; 1.34.8;
Add `l_poll' to `struct linesw' and provide an xxxpoll() entry point
in each tty driver to indirect through it.

This allows tty line-disciplines to handle poll(2) system calls.
 1.33  01-Feb-2001  leo branches: 1.33.2;
Fix fallout from lastest tty changes.
 1.32  02-Nov-2000  eeh Adapt to new line discipline scheme.
 1.31  29-Mar-2000  leo Nuke a bunch of cf_unit abuses.
 1.30  11-Feb-1999  mycroft branches: 1.30.8;
Minor cleanup.
Make the initializer for BAUDLO depend on PCLK directly; it was incorrect on
some ports where PCLK is not 4.9152MHz.
XXX Is the default value actually used?
 1.29  25-Mar-1998  leo Sync with latest tty changes.
 1.28  12-Jan-1998  thorpej Update for changes to config.
 1.27  10-Mar-1997  leo Use vme_mask, not sys_mask to enable the SCC interrupt.
 1.26  21-Jan-1997  leo branches: 1.26.4;
Don't set the PA_SER2 bit by default, this has the nasty side effect that
it disables the IDE hardware on the Falcon (Thanks Markus ;-) ). A function
is provided to toggle the bit.
 1.25  20-Dec-1996  leo branches: 1.25.2;
Get rid of BROKEN_INDIRECT_CONFIG
 1.24  10-Nov-1996  leo Add frequency table for Hades.

 1.20  15-May-1996  leo branches: 1.20.4;
Prototype + -Wall fixes.
 1.19  18-Apr-1996  leo Yet more prototyping and -Wall fixes.
 1.18  27-Mar-1996  leo Take out direct access to the YM2149. The chip definitions are moved
from video.h to ym2149reg.h.
 1.17  17-Mar-1996  thorpej New device attachment scheme:

- split softc size and match/attach out from cfdriver into
a new struct cfattach.

- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.
 1.16  08-Mar-1996  leo Fix a bug in the DCD handling. Because the state of the DCD line was
kept in a soft-copy that wasn't initialized on open, it sometimes happend
that a change of the carrier got lost. Also fixed some prototypes.
 1.15  22-Feb-1996  leo First bunch of changes due to stricter prototype checking.
 1.14  23-Jan-1996  leo Fixes 'hanging' problem when closing a serial port.
 1.13  25-Dec-1995  leo - Remove an unwanted interference between the 2 channels.
- Allocate the ringbuffer on a channel's first open.
 1.12  16-Dec-1995  leo Correct PCLK value.
 1.11  03-Dec-1995  leo Return a more sensible errno when someone is trying to set the unsupported
mdmbuf option.
 1.10  30-Nov-1995  jtc merge in changes from 1.1 release branch
 1.9  23-Sep-1995  leo branches: 1.9.2;
Make sure the prototypes and inline definitions are included.
 1.8  20-Aug-1995  leo - make sure that there is 1 pending software interrupt max.
- read status before character, so the status won't be lost (Thomas Gerner)
- accumulate as much interrupts as possible in zshard()
 1.7  28-Jun-1995  cgd note that most of dev/ic's contents have changed names
 1.6  28-May-1995  leo According to diffs from Waldi Raven:
Make speed/clock-source selection smarter. This makes the baudrates more
accurate and allows speeds upto 115k baud.
 1.5  14-May-1995  leo Don't mess with SCU on the Falcon.
 1.4  22-Apr-1995  leo Adapt for new conf.h:
- Add xxxtty() functions
- Remove xxx_tty array
 1.3  11-Apr-1995  mycroft Undo accidental change.
 1.2  11-Apr-1995  mycroft Use global 8530 defs.
 1.1  26-Mar-1995  leo branches: 1.1.1;

 1.30.8.1  20-Nov-2000  bouyer Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

 1.34.4.1  13-Oct-2001  fvdl Revert the t_dev -> t_devvp change in struct tty. The way that tty
structs are currently used (especially by console ttys) aren't
ready for it, and this will require quite a few changes.
