 1.57  20-Dec-2023  thorpej Remove unnecessary <sys/malloc.h> include.
 1.56  06-Jan-2023  tsutsui TAB/spaces/indents cleanup.
 1.55  26-Jun-2022  tsutsui Use aprint_*(9) for device attach messages.
 1.54  26-Jun-2022  tsutsui Make local devsw functions static.

No visible regression on TT030.
 1.53  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.52  27-Apr-2021  thorpej branches: 1.52.6;
The Amiga and Atari ports abuse some autoconfiguration internals as part
of their early console bring-up, so we need to expose some of the new
internals to them and adapt the call sites.
 1.51  24-Apr-2021  thorpej branches: 1.51.2;
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  29-Jun-2019  tsutsui branches: 1.50.12;
Make local functions static.
 1.49  25-Jul-2014  dholland branches: 1.49.28;
Add d_discard to all struct cdevsw instances I could find.

All have been set to "nodiscard"; some should get a real implementation.
 1.48  16-Mar-2014  dholland branches: 1.48.2;
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.
 1.47  30-Jun-2011  wiz branches: 1.47.2; 1.47.12; 1.47.16;
dependant -> dependent
 1.46  05-Jun-2011  matt A few missed device_t, cfdata_t cleanups
 1.45  05-Jun-2011  tsutsui - use CFATTACH_DECL_NEW() (no softc)
- use device_t, cfdata_t etc.
 1.44  08-Feb-2011  rmind branches: 1.44.2;
Remove clause 3 (UCB advertising clause) from the University of Utah
copyright. Confirmed by Mike Hibler, mike at cs.utah.edu - thanks!
Also, merge UCB and Utah copyright texts back into one, as they
originally were.

Extra verification by snj@.
 1.43  13-Apr-2010  tsutsui branches: 1.43.2; 1.43.4;
Misc KNF.
 1.42  13-Apr-2010  tsutsui Include "ioconf.h" to declare struct cfdriver foo_cd.
 1.41  19-Jul-2009  tsutsui branches: 1.41.2; 1.41.4;
Remove extra whitespace added by a dumb tool which replaced bcopy with memcpy.
 1.40  18-Mar-2009  cegger bcopy -> memcpy
 1.39  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.
 1.38  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.)
 1.37  14-Mar-2009  dsl Remove all the __P() from sys (excluding sys/dist)
Diff checked with grep and MK1 eyeball.
i386 and amd64 GENERIC and sys still build.
 1.36  04-Mar-2007  christos branches: 1.36.44; 1.36.52; 1.36.58;
Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
 1.35  11-Dec-2005  christos branches: 1.35.26;
merge ktrace-lwp.
 1.34  25-Mar-2004  leo branches: 1.34.16;
Licence cleanup (suggested by wiz).
 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  15-Jul-2003  lukem __KERNEL_RCSID()
 1.31  23-Oct-2002  jdolecek branches: 1.31.6;
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
 1.30  10-Oct-2002  jdolecek replace the somewhat strange poll routine with standard nopoll() (a.k.a
seltrue())
 1.29  02-Oct-2002  thorpej Use CFATTACH_DECL().
 1.28  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.27  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.
 1.26  17-Mar-2002  atatat branches: 1.26.4;
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.
 1.25  29-Jun-2000  mrg branches: 1.25.2; 1.25.4; 1.25.8;
remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h>
 1.24  26-Jun-2000  mrg remove/move more mach vm header files:

<vm/pglist.h> -> <uvm/uvm_pglist.h>
<vm/vm_inherit.h> -> <uvm/uvm_inherit.h>
<vm/vm_kern.h> -> into <uvm/uvm_extern.h>
<vm/vm_object.h> -> nothing
<vm/vm_pager.h> -> into <uvm/uvm_pager.h>

also includes a bunch of <vm/vm_page.h> include removals (due to redudancy
with <vm/vm.h>), and a scattering of other similar headers.
 1.23  26-Jun-2000  simonb Change the kernel mmap interface so that the offset to map is an
"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes. Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".

Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.
 1.22  20-Dec-1998  thomas branches: 1.22.8; 1.22.18;
Changed grf mmap that it is closer to XFree. VGA memory on et4000/et6000
is now at offset 0xa0000.
 1.21  12-Jan-1998  thorpej Update for changes to config.
 1.20  25-Apr-1997  leo - Provide the reasonable size that can/may be mmap-ed. This might differ
from the current frame buffer size.
- The et-driver now allows for a 16Kb io-region (was 8Kb) that can be
mapped. The XFree server uses this.
 1.19  26-Feb-1997  leo Fix a kernel-dump that occurred when accessing a grf-device that was configured
in the config file but not found by the autoconfig code.
 1.18  10-Jan-1997  leo branches: 1.18.6;
Allow the control registers to be mapped too.
 1.17  20-Dec-1996  leo Get rid of BROKEN_INDIRECT_CONFIG
 1.16  13-Oct-1996  christos backout previous kprintf changes
 1.15  11-Oct-1996  christos printf -> kprintf, sprintf -> ksprintf
 1.14  04-Oct-1996  leo Checkpointing my et4000 work. Note that the et-console will not be
functional until the minimal pci-support is checked in.
 1.13  25-Sep-1996  leo Catchup with -current:
- Extra argument to boot()
- select -> poll
 1.12  16-Sep-1996  leo Prepare for (soon to come) et4000 PCI console.
 1.11  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).
 1.10  18-Apr-1996  leo Yet more prototyping and -Wall fixes.
 1.9  20-Mar-1996  leo Fix typo in neew config changes.
 1.8  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.
 1.7  22-Feb-1996  leo First bunch of changes due to stricter prototype checking.
 1.6  26-Jun-1995  leo Sync grf with underlying view on open.
 1.5  09-Jun-1995  leo Fix grfmmap()
 1.4  28-May-1995  leo Remove the pointer to view_t from the grf-structure, use viewview(dev)
to obtain the pointer instead. This removes a kernel-crash that happened
when something was written to the console while the console was being
resized.
 1.3  21-May-1995  leo Minor fixes.
 1.2  10-Apr-1995  mycroft map --> mmap
 1.1  26-Mar-1995  leo branches: 1.1.1;

 1.22.8.1  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.
