 1.65  17-Sep-2023  andvar remove unneeded whitespace in empty line from my previous commit.
 1.64  16-Sep-2023  andvar sh3/sci(4): replace undefined scistatus with DPRINTF.

Fixes the build with SCI_DEBUG enabled.
 1.63  21-Nov-2020  thorpej malloc(9) -> kmem(9)
 1.62  10-Nov-2019  chs branches: 1.62.8;
in many device attach paths, allocate memory with M_WAITOK instead of M_NOWAIT
and remove code to handle failures that can no longer happen.
 1.61  15-Nov-2014  christos branches: 1.61.20;
centralize the call unit / dialout macros
 1.60  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.
 1.59  19-Jun-2014  msaitoh fix -Werror=unused-but-set-variable compile error
 1.58  16-Mar-2014  dholland branches: 1.58.2;
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.
 1.57  12-Dec-2012  tsutsui branches: 1.57.2;
Fix one more device/softc split error:
- set sc->sc_dev properly
 1.56  29-Oct-2012  chs fix device/softc split errors.
 1.55  27-Oct-2012  chs split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.
 1.54  02-Feb-2012  tls branches: 1.54.6;
Entropy-pool implementation move and cleanup.

1) Move core entropy-pool code and source/sink/sample management code
to sys/kern from sys/dev.

2) Remove use of NRND as test for presence of entropy-pool code throughout
source tree.

3) Remove use of RND_ENABLED in device drivers as microoptimization to
avoid expensive operations on disabled entropy sources; make the
rnd_add calls do this directly so all callers benefit.

4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might
have lead to slight entropy overestimation for some sources.

5) Add new source types for environmental sensors, power sensors, VM
system events, and skew between clocks, with a sample implementation
for each.

ok releng to go in before the branch due to the difficulty of later
pullup (widespread #ifdef removal and moved files). Tested with release
builds on amd64 and evbarm and live testing on amd64.
 1.53  24-Apr-2011  rmind branches: 1.53.4; 1.53.8;
Rename ttymalloc() to tty_alloc(), and ttyfree() to tty_free() for
consistency. Remove some unnecessary malloc.h inclusions as well.
 1.52  14-Mar-2009  dsl branches: 1.52.4; 1.52.6;
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.)
 1.51  13-Jun-2008  cegger branches: 1.51.4; 1.51.10;
use device_lookup_private to get softc
 1.50  28-Apr-2008  martin branches: 1.50.2; 1.50.4;
Remove clause 3 and 4 from TNF licenses
 1.49  19-Nov-2007  ad branches: 1.49.14; 1.49.16; 1.49.18;
- Factor out too many copies of the same bit of tty code.
- Fix another tty signalling/wakeup problem.
 1.48  17-Oct-2007  garbled branches: 1.48.2;
Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.
 1.47  09-Jul-2007  ad branches: 1.47.8; 1.47.10; 1.47.14;
Merge some of the less invasive changes from the vmlocking branch:

- kthread, callout, devsw API changes
- select()/poll() improvements
- miscellaneous MT safety improvements
 1.46  04-Mar-2007  christos branches: 1.46.2; 1.46.4; 1.46.10;
Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
 1.45  01-Oct-2006  elad branches: 1.45.4;
More from Matt Fleming:

Adapt to KAUTH_DEVICE_TTY_PRIVSET and KAUTH_DEVICE_TTY_OPEN.
 1.44  01-Oct-2006  elad Adapt MD code to KAUTH_DEVICE_TTY_OPEN. Patch from Matt Fleming, thanks!
 1.43  23-Jul-2006  ad branches: 1.43.4; 1.43.6;
Use the LWP cached credentials where sane.
 1.42  14-May-2006  elad integrate kauth.
 1.41  07-Mar-2006  uebayasi branches: 1.41.2; 1.41.4;
* Don't define SET/CLR/ISSET locally.
* Avoid shadow in a pointer-to-function declaration.
 1.40  20-Feb-2006  thorpej branches: 1.40.2;
Use device_is_active() rather than testing dv_flags for DVF_ACTIVE
directly.
 1.39  11-Dec-2005  christos branches: 1.39.2; 1.39.4; 1.39.6;
merge ktrace-lwp.
 1.38  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.
 1.37  11-Mar-2005  matt branches: 1.37.4;
Don't compare scalars against NULL, use 0.
 1.36  13-Dec-2004  chs branches: 1.36.2; 1.36.4;
for drivers that support only one instance, use a global variable to ensure
that only one instance is configured rather than requiring that its
unit number be zero.
 1.35  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.
 1.34  15-Jul-2003  lukem __KERNEL_RCSID()
 1.33  23-Oct-2002  jdolecek branches: 1.33.6;
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
 1.32  02-Oct-2002  thorpej Add trailing ; to CFATTACH_DECL.
 1.31  01-Oct-2002  thorpej Use CFATTACH_DECL().
 1.30  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.29  27-Sep-2002  thorpej Rather than referencing the cfdriver directly in the cfdata entries,
instead use a string naming the driver. The cfdriver is then looked
up in a list which is built at run-time.
 1.28  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.
 1.27  16-Aug-2002  msaitoh remove extra CRLF conversion
 1.26  19-May-2002  msaitoh branches: 1.26.4;
fix some overflow cases.
 1.25  28-Apr-2002  uch branches: 1.25.2;
Use "#define<tab>", white space nits.
 1.24  28-Apr-2002  msaitoh add missing softintr_establish() call.
 1.23  26-Apr-2002  msaitoh fix around PTR and PDR
 1.22  24-Mar-2002  uch Rework interrupt code.
+ Fully utilize SH SR.I[0:3] interrupt level.
+ software interrupt is emulated by TMU1, 2 one shot interrupt.
+ implement generic soft interrupts.
+ implement clockframe correctly.
 1.21  17-Mar-2002  atatat 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.
 1.20  24-Feb-2002  uch use sh_clock_get_pclock() instead of PCLOCK.
 1.19  22-Feb-2002  uch New NetBSD/sh3 clock framework.
+ hardclock source is moved from TMU1 to TMU0.
+ SH3/SH4 common kernel support.
+ PCLOCK estimation.
+ remove duplicated code.
 1.18  12-Feb-2002  uch ANSIfy KNF.
 1.17  01-Feb-2002  uch if PCLOCK isn't setted, use estimated value calculated by kernel.
 1.16  10-Sep-2001  msaitoh add missing check for framing error
 1.15  12-Jun-2001  wiz branches: 1.15.2; 1.15.4;
receive, not recieve
 1.14  30-May-2001  lukem add missing #include "opt_kgdb.h"
 1.13  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.
 1.12  14-Jan-2001  thorpej branches: 1.12.2;
Rename __GENERIC_SOFT_INTERRUPTS to __HAVE_GENERIC_SOFT_INTERRUPTS,
and place the definition in <machine/types.h>. This can now be used
as a flag to indicate whether or not <machine/intr.h> can be included
to get the generic soft interrupt API.
 1.11  22-Nov-2000  msaitoh - fix \n conversion from \n\r to \r\n
- cleanup
 1.10  02-Nov-2000  eeh Adapt to new line discipline scheme.
 1.9  19-Jun-2000  msaitoh branches: 1.9.2;
clear ORER, FER and PER bit of the SCSSR reg.
(This bits aren't cleared automatically)
 1.8  27-Mar-2000  msaitoh branches: 1.8.2;
fix the sci[f]cninit() bugs to work both SCI and SCIF at the same time.
 1.7  23-Mar-2000  thorpej New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.
 1.6  22-Feb-2000  msaitoh bugfixes:
o SCI accesses SCI registers (not SCIF) correctly
o If there is serial inputs in boot time, it could hangup in interrupt routine
o some cleanups(KNF)
 1.5  07-Jan-2000  msaitoh implement send/recieve break signal routines
 1.4  17-Sep-1999  msaitoh branches: 1.4.2;
check SCI(F)CONSOLE
 1.3  16-Sep-1999  msaitoh sync with sci*.h and tmureg.h
 1.2  13-Sep-1999  msaitoh add some comments.
 1.1  13-Sep-1999  itojun Merge in NetBSD/sh3 from cvs.kame.net repository.

Tree structure:
- sys/arch/sh3: sh3 generic code
As commented, in-chip device drivers are put into sys/arch/sh3/dev.
- sys/arch/evbsh3: sh3 evaluation boards (pure sh3 CPU, no fancy external HW)
- sys/arch/mmeye: Brains mmEye, www.brains.co.jp
MI source code includes couple of #ifdef for sh3-coff support.
(sh3 uses coff or elf)

Needs some more improvements, especialy in sys/arch/sh3/conf/files.sh3,
to compile the tree (due to last minute tree structure change).
 1.4.2.4  18-Jan-2001  bouyer Sync with head (for UBC+NFS fixes, mostly).

 1.4.2.1  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.
