 1.53  23-Sep-2024  andvar s/dicipline/discipline/ in debug message.
 1.52  07-Aug-2021  thorpej branches: 1.52.12;
Merge thorpej-cfargs2.
 1.51  24-Apr-2021  thorpej branches: 1.51.8;
Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).
 1.50  21-Nov-2020  thorpej branches: 1.50.2;
malloc(9) -> kmem(9)
 1.49  15-Nov-2014  christos branches: 1.49.32;
centralize the call unit / dialout macros
 1.48  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.
 1.47  16-Mar-2014  dholland branches: 1.47.2;
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.
 1.46  27-Oct-2012  chs branches: 1.46.2;
split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.
 1.45  24-Apr-2011  rmind branches: 1.45.4; 1.45.14;
Rename ttymalloc() to tty_alloc(), and ttyfree() to tty_free() for
consistency. Remove some unnecessary malloc.h inclusions as well.
 1.44  20-Jul-2010  tsutsui branches: 1.44.2;
Replace callout(9) with softint(9) which is more appropriate there.
Inspired by PR port-hpcmips/43472 and tested by Risto Sainio.
 1.43  16-Jul-2010  tsutsui Fix a wrong arg for callout_reset(9) in txcom_txintr(). PR port-hpcmips/43474
 1.42  16-Jul-2010  tsutsui Add missing callout_init(9) calls. PR port-hpcmips/43472
 1.41  14-Mar-2009  dsl branches: 1.41.2; 1.41.4;
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  12-Jun-2008  tsutsui branches: 1.40.4; 1.40.6; 1.40.10;
Use device_lookup_private() to get softc.

 1.35  21-Feb-2007  thorpej Replace the Mach-derived boolean_t type with the C99 bool type. A

privileges. Noted by David Holland in PR kern/31126.
 1.24  12-Jun-2004  uch branches: 1.24.12;
When serial console boot, don't find power supply port from
config_hook. Windows CE already power on it, and config_hook is not
initialized yet.
 1.23  26-Dec-2003  shin initialize variable 'err' properly.
found by gcc -Wuninitialized.
 1.22  15-Jul-2003  lukem __KERNEL_RCSID()
 1.21  21-Mar-2003  nakayama branches: 1.21.2;
Follow a struct consdev changes.
Pointed out by Tsuyoshi AKIHO in the port-hpcmips-ja mailing list.
 1.20  23-Oct-2002  jdolecek 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
 1.19  02-Oct-2002  thorpej Use CFATTACH_DECL().
 1.18  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.17  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.
 1.16  17-Mar-2002  atatat branches: 1.16.4;
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.
 1.15  29-Jan-2002  uch clean up debug print and configuration.
 1.14  14-Jun-2001  uch branches: 1.14.2; 1.14.4; 1.14.8;
ANSI KNF. and change my copyright to TNF copyright.
 1.13  13-Jun-2001  uch (TX39) switch from TX local I/O manager to hpcio
 1.12  02-May-2001  scw 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.
 1.11  04-Jan-2001  sato branches: 1.11.2;
make compilable.
 1.10  02-Nov-2000  eeh branches: 1.10.2;
Adapt to the new line discipline scheme.
 1.9  22-Oct-2000  uch new I/O modules framework for TX based system.
 1.8  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.
 1.7  06-Mar-2000  thorpej - Implement cnbell() -- ring the console bell. The cn_bell entrypoint
is optional.
- Add cn_bell to statically allocated consdevs as appropriate.
 1.6  16-Jan-2000  uch add platform dependent TX39 UART module hook.
remove delay from tc5165buf interrupt handler.
backlight config_hook.

 1.4  06-Jan-2000  uch change overrun interrupt treatment.
 1.3  26-Dec-1999  uch branches: 1.3.2;

 1.10.2.2  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.
 1.10.2.1  02-Nov-2000  bouyer file txcom.c was added on branch thorpej_scsipi on 2000-11-20 20:47:38 +0000

 1.14.4.2  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.
 1.14.4.1  10-Oct-2001  fvdl Convert all remaining devices.
