 1.31  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.30  24-Apr-2021  thorpej branches: 1.30.8;
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?).
 1.29  05-Feb-2018  mrg branches: 1.29.20;
fixes for GCC 6.4:

- fix an indentation issue in radioioctl().
- fix an indentation issue in mpt_run_xfer().
- grep's printline() has some {} placement issues.
 1.28  28-Oct-2017  riastradh Kill some more extern cfdriver xyz_cd in favour of #include "ioconf.h".
 1.27  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.
 1.26  16-Mar-2014  dholland branches: 1.26.2;
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.
 1.25  23-Feb-2011  dyoung branches: 1.25.4; 1.25.14; 1.25.18;
Correct device_t/softc split and, while I am here, delete commented-out
code. Patrick Welche says that this patch fixes the problem that he
reported on current-users@.

BTW, sc_dev is initialized in radioattach(), but I do not see where it
is used.
 1.24  21-Jan-2010  dyoung branches: 1.24.4; 1.24.6; 1.24.8;
All that the activation hook radioactivate() did was to change
sc_dying, and nothing in the driver examines sc_dying, so get rid of
radioactivate() and sc_dying.
 1.23  06-Dec-2009  dyoung Simplify these device-activation hooks using the following semantic
patch.

XXX sc_dying must die.

 1.22  09-Jul-2008  joerg - use aprint in attach
- split device/softc
- move softc definition into source to make explicit that it is local
- reduce namespace pollution
 1.21  08-Jun-2008  tsutsui branches: 1.21.2; 1.21.4;
Use device_lookup_private() rather than using cd_devs[] directly to get softc.

XXX maybe we should change a type of cd_devs[] in struct cfdriver
from (void *) to device_t.
 1.20  04-Mar-2007  christos branches: 1.20.36; 1.20.38; 1.20.40; 1.20.42;
Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
 1.19  16-Nov-2006  christos branches: 1.19.4;
__unused removal on arguments; approved by core.
 1.18  12-Oct-2006  christos - sprinkle __unused on function decls.
- fix a couple of unused bugs
- no more -Wno-unused for i386
 1.17  03-Sep-2006  christos branches: 1.17.2; 1.17.4;
add missing initializer
 1.16  28-Mar-2006  thorpej Use device_unit().
 1.15  11-Dec-2005  christos branches: 1.15.4; 1.15.6; 1.15.8; 1.15.10; 1.15.12;
merge ktrace-lwp.
 1.14  27-Feb-2005  perry branches: 1.14.4;
nuke trailing whitespace
 1.13  29-Oct-2004  yamt branches: 1.13.4; 1.13.6;
constify audio_hw_if, midi_hw_if, and radio_hw_if.
 1.12  19-Oct-2003  simonb Remove unreachable break after return and goto statements.
 1.11  29-Jun-2003  fvdl branches: 1.11.2;
Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.
 1.10  28-Jun-2003  darrenr Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V
 1.9  01-Jan-2003  thorpej Use aprint_normal() in cfprint routines.
 1.8  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
 1.7  02-Oct-2002  thorpej Add trailing ; to CFATTACH_DECL.
 1.6  30-Sep-2002  thorpej Use CFATTACH_DECL().
 1.5  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.4  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.
 1.3  05-Jan-2002  augustss branches: 1.3.2; 1.3.4; 1.3.12;
Initialize _ca struct right.
 1.2  02-Jan-2002  augustss Support detach.

Hi Perry!

 1.11.2.1  02-Jul-2003  darrenr Apply the aborted ktrace-lwp changes to a specific branch. This is just for
others to review, I'm concerned that patch fuziness may have resulted in some
errant code being generated but I'll look at that later by comparing the diff
from the base to the branch with the file I attempt to apply to it. This will,
at the very least, put the changes in a better context for others to review
them and attempt to tinker with removing passing of 'struct lwp' through
the kernel.

 1.20.36.3  29-Jun-2008  mjf Sync with HEAD.
 1.20.36.2  06-Apr-2008  mjf - after some discussion with agc@ i agreed it would be a good idea to move
device_unregister_* to device_deregister_* to be more like the pmf(9)
functions, especially since a lot of the time the function calls are next
to each other.

- add device_register_name() support for dk(4).
 1.20.36.1  05-Apr-2008  mjf - add "file-system DEVFS" and "pseudo-device devfsctl" to conf/std seeing
as these are always needed.

- convert many, many drivers over to the New Devfs World Order. For a
list of device drivers yet to be converted see,
http://www.netbsd.org/~mjf/devfs-todo.html.

- add a new device_unregister_all(device_t) function to remove all device
names associated with a device_t, which saves us having to construct
device names when the driver is detached.

- add a DEV_AUDIO type for devices.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs. ("Protocol error: too many arguments")
 1.26.2.1  10-Aug-2014  tls Rebase.
 1.29.20.1  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.
 1.30.8.1  04-Aug-2021  thorpej Adapt to CFARGS().
