 1.60  21-Oct-2021  andvar fix various typos, mainly in comments, but also in man pages and log messages.
 1.59  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.58  24-Apr-2021  thorpej branches: 1.58.8;
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?).
 1.57  25-Jul-2014  dholland branches: 1.57.8; 1.57.18; 1.57.42;
Add d_discard to all struct cdevsw instances I could find.

All have been set to "nodiscard"; some should get a real implementation.
 1.56  16-Mar-2014  dholland branches: 1.56.2;
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.
 1.55  27-Oct-2012  chs branches: 1.55.2;
split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.
 1.54  24-Apr-2011  rmind branches: 1.54.4; 1.54.14;
Rename ttymalloc() to tty_alloc(), and ttyfree() to tty_free() for
consistency. Remove some unnecessary malloc.h inclusions as well.
 1.53  26-Oct-2009  cegger branches: 1.53.4; 1.53.6;
kill extra whitespaces
reviewed by tsutsui@
 1.52  19-May-2009  phx Removed old Amiga-specific "sicallback" software interrupts and replaced
them by MI softints. Approved by "is".
 1.51  18-Mar-2009  cegger bcopy -> memcpy
 1.50  11-Jun-2008  tsutsui branches: 1.50.4; 1.50.10;

 1.49  25-May-2008  ad branches: 1.49.2;
Properly fix the "hanging in tty" bug that was worked around with cv_wakeup()
some time again.
 1.48  19-Nov-2007  ad branches: 1.48.14; 1.48.16; 1.48.18; 1.48.20;

 1.47  07-Nov-2007  ad Merge tty changes from the vmlocking branch.
 1.46  04-Mar-2007  christos branches: 1.46.2; 1.46.18; 1.46.20; 1.46.24; 1.46.26;
Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
 1.45  24-Jan-2007  hubertf branches: 1.45.2;
Remove duplicate #includes, patch contributed in private mail
by Slava Semushin <slava.semushin@gmail.com>.

To verify that no nasty side effects of duplicate includes (or their
removal) have an effect here, I've compiled an i386/ALL kernel with
and without the patch, and the only difference in the resulting .o
files was in shifted line numbers in some assert() calls.
The comparison of the .o files was based on the output of "objdump -D".

Thanks to martin@ for the input on testing.
 1.44  01-Oct-2006  elad More from Matt Fleming:

Adapt to KAUTH_DEVICE_TTY_PRIVSET and KAUTH_DEVICE_TTY_OPEN.
 1.43  01-Oct-2006  elad Adapt MD code to KAUTH_DEVICE_TTY_OPEN, batch #2 from Matt Fleming, thanks!

Also, add forgotten splx() calls in some places.
 1.42  01-Oct-2006  elad Adapt MD code to KAUTH_DEVICE_TTY_OPEN. Patch from Matt Fleming, thanks!
 1.41  23-Jul-2006  ad branches: 1.41.4; 1.41.6;

 1.40  14-May-2006  elad integrate kauth.
 1.39  26-Mar-2006  thorpej Use device_unit().
 1.38  11-Dec-2005  christos branches: 1.38.4; 1.38.6; 1.38.8; 1.38.10; 1.38.12;
merge ktrace-lwp.
 1.37  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.
 1.36  13-Jun-2005  jmc branches: 1.36.2;
Fix a ton of const/volatile issues shown with new warning flags
 1.35  25-Apr-2004  matt Constify the speedtab arrays
 1.34  28-Mar-2004  mhitch Remove license clauses 3 and 4 in my licenses.
 1.33  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.
 1.32  23-Oct-2002  jdolecek branches: 1.32.6;
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
 1.31  02-Oct-2002  thorpej Use CFATTACH_DECL().
 1.30  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.29  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.
 1.28  17-Mar-2002  atatat branches: 1.28.4;
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.
 1.27  17-Feb-2002  veego Add a missing ) from an 6 year old cleanup commit (rev 1.10):
s/sizeof(struct mfcp_softc,/sizeof(struct mfcp_softc),/
Noticed by Nagilum on irc.
 1.26  28-Jan-2002  aymeric add __KERNEL_RCSID as suggested by Luke Mewburn
 1.25  26-Jan-2002  aymeric - ANSIfy
- remove some trailing spaces/tabs
- minor style nits
 1.24  30-May-2001  lukem branches: 1.24.2; 1.24.4; 1.24.8;
add missing #include "opt_kgdb.h"
 1.23  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.
 1.22  13-Jan-2001  aymeric branches: 1.22.2;
Make these compile again, plus minor aesthetic changes.
 1.21  02-Nov-2000  eeh Adapt to new line discipline scheme.
 1.20  01-Sep-1998  mhitch branches: 1.20.12;
Quick fix for TS_WOPEN -> t_wopen change. Compiles and works.

 1.18  23-Dec-1996  veego Get rid of __BROKEN_INDIRECT_CONFIG.
 1.17  13-Oct-1996  christos backout previous kprintf change
 1.16  10-Oct-1996  christos printf -> kprintf, sprintf -> ksprintf
 1.15  02-Sep-1996  mycroft tty stop functions really should return void, not int, and certainly not both.
 1.14  27-Aug-1996  cgd change cfprint_t type definition to take a const char *, rather than
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).
 1.13  06-Jun-1996  mhitch Add tty_attach() calls for pstat -t. Closes PR #2519
 1.12  21-Apr-1996  veego branches: 1.12.4;
- Cleanup for -Wall and -Wstrict-prototypes
- Added support for multiple floppy drives
- CyberVision64:
- has now a real console mode
- another bugfix for boards with the new S3 chip
- Ariadne:
- fixed crashes with aeput (mbuf failure)
 1.11  17-Mar-1996  mhitch Clean up typos and other errors from new device attachment changes.
 1.10  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.

Now use amiga HW for soft interrupts, non-contig options (2 or many chunks),
interrupt handler lists, 4066 ethernet, 1291 scsi, option to defer level 6
interrupts to level 4 (deal with icky built-in serial port)
 1.1  28-Dec-1994  chopps consolidate the zbusses. le support for multiple tx buffs and full use of 32k

 1.57.42.1  21-Mar-2021  thorpej Give config_found() the same variadic arguments treatment as
config_search(). This commit only adds the CFARG_EOL sentinel
to the existing config_found() calls. Conversion of config_found_sm_loc()
and config_found_ia() call sites will be in subsequent commits.
 1.57.18.1  27-Apr-2017  pgoyette Restore all work from the former pgoyette-localcount branch (which is
now abandoned doe to cvs merge botch).

The branch now builds, and installs via anita. There are still some
problems (cgd is non-functional and all atf tests time-out) but they
will get resolved soon.
 1.57.8.2  20-Jul-2016  pgoyette Redo previous. Rather than separately extracting the device_t, we can
rely on sc->sc_dev when we need to call device_release().
 1.57.8.1  19-Jul-2016  pgoyette Instead of repeatedly typing the conditional initialization of the
.d_localcount members in the various {b,c}devsw, define an initializer
macro and use it. This also removes the need for defining new symbols
for each 'struct localcount'.

As suggested by riastradh@
 1.58.8.1  03-Aug-2021  thorpej Adapt to CFARGS().
