 1.38  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.37  24-Apr-2021  thorpej branches: 1.37.8;
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?).

malloc(9) -> kmem(9)
 1.35  14-Jun-2020  chs branches: 1.35.2;
replace EX_NOWAIT with EX_WAITOK in device attach methods.
remove checks for failures that can no longer occur.
 1.34  14-Mar-2019  thorpej Use copyin(), not fusword().
 1.33  22-May-2017  ragge branches: 1.33.10;
Update copyright notice for Ludd (remove clause 3 & 4).
 1.32  07-Jul-2016  msaitoh KNF. Remove extra spaces. No functional change.
 1.31  05-Jul-2015  matt Revamped QVSS (VCB01) support. (from Charles Dickman)
 1.30  25-Jul-2014  dholland branches: 1.30.4;
Add d_discard to all struct cdevsw instances I could find.

All have been set to "nodiscard"; some should get a real implementation.
 1.29  16-Mar-2014  dholland branches: 1.29.2;
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.
 1.28  30-Jun-2011  wiz branches: 1.28.2; 1.28.12; 1.28.16;
dependant -> dependent
 1.27  21-Nov-2009  rmind - Use lwp_getpcb() on VAX, clean from struct user usage.
- Include sys/user.h in MD proc.h .
 1.26  26-Oct-2009  cegger kill extra whitespaces
reviewed by tsutsui@
 1.25  18-Mar-2009  cegger bcopy -> memcpy
 1.24  18-Mar-2009  cegger bzero -> memset
 1.23  18-Mar-2009  cegger Ansify function definitions w/o arguments. Generated with sed.
 1.22  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.
 1.21  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.)
 1.20  11-Mar-2008  matt branches: 1.20.4; 1.20.12; 1.20.18;
Rototill the vax code. Switch to devicet/PRIV_ALLOC. Cleanup vax autoconf
code. Move to prototype definitions. staticfy, constify, avoid casting.
Use device_* accessors.
 1.19  01-Mar-2008  rmind Welcome to 4.99.55:

- Add a lot of missing selinit() and seldestroy() calls.

- Merge selwakeup() and selnotify() calls into a single selnotify().

- Add an additional 'events' argument to selnotify() call. It will
indicate which event (POLL_IN, POLL_OUT, etc) happen. If unknown,
zero may be used.

Note: please pass appropriate value of 'events' where possible.
Proposed on: <tech-kern>
 1.18  19-Nov-2007  ad branches: 1.18.10; 1.18.14;
- Factor out too many copies of the same bit of tty code.
- Fix another tty signalling/wakeup problem.
 1.17  04-Mar-2007  christos branches: 1.17.2; 1.17.18; 1.17.20; 1.17.24; 1.17.26;
Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
 1.16  26-Nov-2005  thorpej branches: 1.16.26;
Use t_linesw instead of (the non-existent) t_line.
 1.15  13-Feb-2004  wiz branches: 1.15.16; 1.15.24;
Uppercase CPU, plural is CPUs.
 1.14  04-Jan-2004  wiz Spell controller with two ls. Inspired by miod@openbsd.
 1.13  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.
 1.12  15-Jul-2003  lukem __KERNEL_RCSID()
 1.11  23-Oct-2002  jdolecek branches: 1.11.6;
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
 1.10  25-Sep-2002  thorpej Don't include <sys/map.h>.
 1.9  19-Sep-2002  ragge Do not include <sys/clist.h>, it's not used in NetBSD at all.
 1.8  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.
 1.7  17-Mar-2002  atatat branches: 1.7.4;
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.

seperate -> separate
 1.5  02-May-2001  scw branches: 1.5.2;
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.
 1.4  02-Nov-2000  eeh branches: 1.4.2;
Adapt to new line discipline scheme.
 1.3  01-Jan-1999  ragge branches: 1.3.8;
Giant change: NBPG now set to 4k and CLSIZE == 1 for vax. This change
made a whole bunch of annoying bugs disappear; mostly depending on
bad use of NBPG in non-MD code. The VAX port was the only port that
used this historical "feature".

The CL* macros should probably go away totally, there is no reason
at all to keep them.
 1.2  02-Sep-1996  mycroft tty stop functions really should return void, not int, and certainly not both.
 1.1  18-Aug-1996  jonathan Import framebuffer drivers from 4.4-Lite2 as the root for NetBSD drivers.
Only change from Lite (or lite2, qv.c and qd.c do not change) is adding
NetBSD RCS ids.

 1.6.2.1  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.

 1.36.2.2  02-Apr-2021  thorpej config_found_ia() -> config_found() w/ CFARG_IATTR.
 1.36.2.1  20-Mar-2021  thorpej The proliferation if config_search_*() and config_found_*() combinations
is a little absurd, so begin to tidy this up:

- Introduce a new cfarg_t enumerated type, that defines the types of
tag-value variadic arguments that can be passed to the various
config_*() functions (CFARG_SUBMATCH, CFARG_IATTR, and CFARG_LOCATORS,
for now, plus a CFARG_EOL sentinel).
- Collapse config_search_*() into config_search() that takes these
variadic arguments.
- Convert all call sites of config_search_*() to the new signature.
Noticed several incorrect usages along the way, which will be
audited in a future commit.
 1.37.8.1  04-Aug-2021  thorpej Adapt to CFARGS().
