 1.59  30-Aug-2023  andvar atari/ser(4): constify "char *str" serstatus() argument to fix SER_DEBUG build.
 1.58  06-Jan-2023  tsutsui TAB/spaces/indents cleanup.
 1.57  26-Jun-2022  tsutsui Make local devsw functions static.

No visible regression on TT030.
 1.56  15-Nov-2014  christos centralize the call unit / dialout macros
 1.55  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.
 1.54  24-Mar-2014  christos branches: 1.54.2;
- remove unused
- use cpu_{g,s}etmodel() (not committed yet)
 1.53  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.
 1.52  24-Apr-2011  rmind branches: 1.52.4; 1.52.14; 1.52.18;
Rename ttymalloc() to tty_alloc(), and ttyfree() to tty_free() for
consistency. Remove some unnecessary malloc.h inclusions as well.
 1.51  10-Apr-2010  tsutsui branches: 1.51.2;
Make local functions static.
 1.50  09-Apr-2010  tsutsui minor constify
 1.49  09-Apr-2010  tsutsui Make options SERCONSOLE (force serial console if DCD is detected)
patchable by binpatch(8) like:
---
# binpatch -s serconsole -r 0 /netbsd
serconsole(0x23bac4): 0x00000001 (1), at offset 0x23bb44 in /netbsd
new value: 0x00000000 (0)
#
---

May work around PR port-atari/39849
(netbsd-ATARITT kernel fails with serial port connected)
and some old TT030 with early revision boards.
 1.48  09-Apr-2010  tsutsui - split device_t/softc
- verbose output on attach as well as zs serial ports
 1.47  09-Apr-2010  tsutsui Include ioconf.h for struct cfdriver.
 1.46  09-Apr-2010  tsutsui Misc KNF.
 1.45  23-Nov-2009  rmind branches: 1.45.2; 1.45.4;
Use lwp_getpcb() on m68k ports, clean from struct user usage.
 1.44  08-Jul-2009  tsutsui Merge local <atari/atari/intr.h> into common <machine/intr.h>.
 1.43  03-Jul-2009  tsutsui Replace traditional MD si_callback() with MI softint(9).
 1.42  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.
 1.41  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.)
 1.40  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.
 1.39  11-Jun-2008  tsutsui branches: 1.39.4; 1.39.6; 1.39.10;
Use device_private() and device_lookup_privat() to get softc.
 1.38  28-Apr-2008  martin branches: 1.38.2; 1.38.4;
Remove clause 3 and 4 from TNF licenses
 1.37  03-Dec-2007  ad branches: 1.37.14; 1.37.16; 1.37.18;
Interrupt handling changes, in discussion since February:

- Reduce available SPL levels for hardware devices to none, vm, sched, high.
- Acquire kernel_lock only for interrupts at IPL_VM.
- Implement threaded soft interrupts.
 1.36  19-Nov-2007  ad - Factor out too many copies of the same bit of tty code.
- Fix another tty signalling/wakeup problem.
 1.35  17-Oct-2007  garbled branches: 1.35.2;
Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.
 1.34  09-Jul-2007  ad branches: 1.34.8; 1.34.10; 1.34.14;
Merge some of the less invasive changes from the vmlocking branch:

- kthread, callout, devsw API changes
- select()/poll() improvements
- miscellaneous MT safety improvements
 1.33  04-Mar-2007  christos branches: 1.33.2; 1.33.4; 1.33.10;
Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
 1.32  01-Oct-2006  elad branches: 1.32.4;
More from Matt Fleming:

Adapt to KAUTH_DEVICE_TTY_PRIVSET and KAUTH_DEVICE_TTY_OPEN.
 1.31  01-Oct-2006  elad Adapt MD code to KAUTH_DEVICE_TTY_OPEN. Patch from Matt Fleming, thanks!
 1.30  23-Jul-2006  ad branches: 1.30.4; 1.30.6;
Use the LWP cached credentials where sane.
 1.29  14-May-2006  elad integrate kauth.
 1.28  06-Mar-2006  he branches: 1.28.2; 1.28.4;
Remove another instance of the macro triplet SET/CLR/ISSET, now
found in <sys/types.h>.
 1.27  11-Dec-2005  christos branches: 1.27.4; 1.27.6; 1.27.8;
merge ktrace-lwp.
 1.26  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.
 1.25  04-Jun-2005  he branches: 1.25.2;
Remove the unused global variable "baud" because it is causing
shadowing warnings.
 1.24  11-Feb-2005  simonb White space nit- don't put a space before/after increment/decrement
operators.
 1.23  07-Aug-2003  agc branches: 1.23.8; 1.23.10;
Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22364, verified by myself.
 1.22  15-Jul-2003  lukem __KERNEL_RCSID()
 1.21  23-Oct-2002  jdolecek branches: 1.21.6;
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
 1.20  02-Oct-2002  thorpej Use CFATTACH_DECL().
 1.19  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.18  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.
 1.17  29-Aug-2002  leo defopt SERCONSOLE
 1.16  30-May-2002  thorpej Don't include params on macro when #undef'ing it.
 1.15  17-Mar-2002  atatat branches: 1.15.4; 1.15.6;
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.
 1.14  02-May-2001  scw branches: 1.14.2; 1.14.4; 1.14.8;
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.
 1.13  11-Apr-2001  leo Adapt these for use on the Milan.
 1.12  02-Nov-2000  eeh branches: 1.12.2;
Adapt to new line discipline scheme.
 1.11  29-Mar-2000  leo Nuke a bunch of cf_unit abuses.
 1.10  23-Mar-2000  thorpej New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.
 1.9  06-Aug-1999  leo branches: 1.9.2;
Change the way that bit's are cleared in the InterruptPending register of
the 68901. Do this now by _assigning_ ~<bit_to_clear> instead of the
previously used 'andb ~<bit_to_clear>'. The latter caused a rwm-cycle that
caused a race condition to happen when an interrupt arrived between the
Read and Modify-Write.
Anyway, this solved my hanging keyboard problem.
 1.8  06-Apr-1999  pk remove duplicate line in copyright.
 1.7  06-Apr-1999  pk Fix garbled word in copyright statement.
 1.6  07-Oct-1998  leo branches: 1.6.6;

 1.3  12-Jan-1998  thorpej Update for changes to config.
 1.2  27-Aug-1997  leo According to Andre Lange, the Hades has the DTR/RTS lines exchanged on
the 68901 UART-port due to a PCB error. Take care of this.
 1.1  25-May-1997  leo branches: 1.1.4;
Add serial driver for 68901 UART (modem1 port).
 1.1.4.1  27-Aug-1997  thorpej Update marc-pcmcia branch from trunk.
 1.6.6.1  07-Apr-1999  pk branches: 1.6.6.1.2;

 1.9.2.1  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.

Disable options SERCONSOLE (force serial console if DCD is detected)
because now it's patchable by binpatch(8).
Enabling serial console by DCD signal could be problematic
on some earlier TT030 (with revision A board), and it's also
annoying for users who connect an active device on the serial port
as mentioned in PR port-atari/39849.
