 1.36  25-Sep-2022  thorpej Remove unnecessary include of <sys/malloc.h>.
 1.35  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.34  24-Apr-2021  thorpej branches: 1.34.8;
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?).
 1.33  09-Nov-2016  macallan branches: 1.33.32;
- use bus_space_mmap()
- pass the right colour depth in ioctl()
should fix PR49639
 1.32  21-Apr-2016  macallan branches: 1.32.2;
RASTERCONSOLE is gone, wsdisplay no longer optional
 1.31  25-Jul-2014  dholland branches: 1.31.4;
Add d_discard to all struct cdevsw instances I could find.

All have been set to "nodiscard"; some should get a real implementation.
 1.30  16-Mar-2014  dholland branches: 1.30.2;
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.
 1.29  11-Jan-2012  macallan branches: 1.29.6; 1.29.10;
use rasops_init(0,0)
 1.28  14-Sep-2010  macallan branches: 1.28.8; 1.28.12;
clear the screen when attaching, not when adding screens since that may
happen much later
while there, call vcons_replay_msgbuf()
 1.27  14-Sep-2010  macallan leave the screen description alone when we're not the console in order to
avoid a NULL deref later on ( which only happens on sparc64 for some reason )
While there, use VCONS_DONT_READ
 1.26  25-Nov-2009  macallan branches: 1.26.2; 1.26.4;
make this compile on sparc64
 1.25  19-Sep-2009  tsutsui Include "ioconf.h" instead of extern struct cfdriver foo_cd decls.
 1.24  18-Sep-2009  tsutsui Split device_t/softc. Tested on SS1+.

XXX: sparc/dev/cgthree.c in Attic had an attachment for cgthree* at obio?
XXX: and sparc/conf/files.sparc still has an entry of nonexistent (or not yet)
XXX: sparc/dev/cgthree_obio.c. Is there any sun4m machine which requires it?
 1.23  12-May-2009  cegger struct device * -> device_t, no functional changes intended.
 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  23-Feb-2009  jdc Mimic cgsix memory corruption fix (bwtwo and cgthree wscons code is
based on cgsix). Original commit message:

Include wsdisplay.h directly in the header to avoid different sizes
of cgsix_softc depending on proper previous includes by the includer
due to #ifdef NWSDISPLAY. Thanks to kmem poison check and DEBUG kernels.
 1.19  01-Jan-2009  jdc branches: 1.19.2;
Back out previous and clear the screen directly.
Pointed out by macallan@.
 1.18  29-Dec-2008  jdc Clear the screen (via rasops) when attaching.
Pointed out by Bill Green on port-sparc.
 1.17  28-Nov-2008  jdc Add wscons/vcons support for cg3.
 1.16  11-Jun-2008  drochner branches: 1.16.2; 1.16.4; 1.16.6;
mechanical changes to use device_private() or device_lookup_private()
to get softcs, makes the code compile under the stricter type checking
introduced earlier today
 1.15  28-Apr-2008  martin branches: 1.15.2; 1.15.4;
Remove clause 3 and 4 from TNF licenses
 1.14  19-Oct-2007  ad branches: 1.14.16; 1.14.18; 1.14.20;
machine/{bus,cpu,intr}.h -> sys/{bus,cpu,intr}.h
 1.13  04-Mar-2007  christos branches: 1.13.2; 1.13.14; 1.13.16; 1.13.20;
Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
 1.12  11-Dec-2005  christos branches: 1.12.26;
merge ktrace-lwp.
 1.11  04-Jun-2005  tsutsui branches: 1.11.2;
Add const.
 1.10  25-Aug-2003  uwe Undo previous as it broke things.

There are some scattered implicit RASTERCONSOLE dependencies,
so there should be a better way.
 1.9  24-Aug-2003  uwe #include "opt_rcons.h"
 1.8  29-Jun-2003  fvdl branches: 1.8.2;
Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.
 1.7  29-Jun-2003  darrenr More changes for providing lwpid for ktrace (sparc GENERIC built)
 1.6  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
 1.5  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.
 1.4  13-Nov-2001  lukem branches: 1.4.8;
add RCSIDs
 1.3  24-Sep-2001  eeh Change bus_space_mmap() signature to the official one.
 1.2  20-Aug-2000  pk branches: 1.2.2; 1.2.4; 1.2.6; 1.2.8;
Move declaration up, before it is used.
 1.1  20-Aug-2000  pk Split & move cgthree from arch/sparc.
 1.2.8.2  10-Oct-2001  fvdl Convert all remaining devices.
 1.2.8.1  01-Oct-2001  fvdl Catch up with -current.
 1.2.6.4  10-Oct-2002  jdolecek sync kqueue with -current; this includes merge of gehenna-devsw branch,
merge of i386 MP branch, and part of autoconf rototil work
 1.2.6.3  28-Jun-2002  jdolecek hook fbkqfilter to leaf drivers' kqfilter
 1.2.6.2  28-Jun-2002  jdolecek prove kqfilter hook; it's very simple equivalent of seltrue()
 1.2.6.1  10-Jan-2002  thorpej Sync kqueue branch with -current.
 1.2.4.4  11-Nov-2002  nathanw Catch up to -current
 1.2.4.3  17-Sep-2002  nathanw Catch up to -current.
 1.2.4.2  14-Nov-2001  nathanw Catch up to -current.
 1.2.4.1  26-Sep-2001  nathanw Catch up to -current.
Again.
 1.2.2.2  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.
 1.2.2.1  20-Aug-2000  bouyer file cgthree.c was added on branch thorpej_scsipi on 2000-11-20 11:43:09 +0000

pmap_init_tmp_pgtbl into arch/x86/x86/pmap.c. Modify the ACPI wakeup
code to restore CR4 before jumping back into kernel space as the large
page option might cover that.
