sh3/scif(4): redefine DPRINTF again, not all SH ports has machine/debug.h.
Those are defined for hpc only.

unbreaks build for evbsh some kernel configs and SFIC_DEBUG still builds.

sh3/scif(4): replace undefined scifstatus with DPRINTF.

fixes the build with SCIF_DEBUG enabled.

Sync w/ HEAD.

malloc(9) -> kmem(9)

Mostly merge changes from HEAD upto 20200411

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.

Sync with HEAD (as of 26th Dec)

Make options SCIFCONSOLE patchable via a variable using gdb(1) etc.

Tested on dreamcast.

centralize the call unit / dialout macros

Rebase to HEAD as of a few days ago.

Rebase.

Add d_discard to all struct cdevsw instances I could find.

All have been set to "nodiscard"; some should get a real implementation.

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")

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.

fixed unused variable warning

merge to -current.

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.

Misc cleanup: use device_* and aprint_*, group declarations, g/c some
dead code, etc.

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.

__KERNEL_RCSID()

Catch up to -current

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

Catch up to -current.

sync kqueue with -current; this includes merge of gehenna-devsw branch,
merge of i386 MP branch, and part of autoconf rototil work

Add trailing ; to CFATTACH_DECL.

Use CFATTACH_DECL().

Declare all cfattach structures const.

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.

Catch up to -current.

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.

file scif.c was added on branch nathanw_sa on 2002-08-27 23:45:23 +0000

fix some overflow cases.

Add device switch.
Replace the access to devsw table and the hard-coded majors with devsw API.

Use "#define<tab>", white space nits.

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.

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.

Initial support for KGDB on the sh3.

New NetBSD/sh3 clock framework.
 + hardclock source is moved from TMU1 to TMU0.
 + SH3/SH4 common kernel support.
 + PCLOCK estimation.
 + remove duplicated code.

ANSIfy KNF.

if PCLOCK isn't setted, use estimated value calculated by kernel.

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.

Convert all remaining devices.

Pull up revisions 1.14,1.18 (requested by msaitoh):
  Fix \n conversion from \n\r to \r\n, and some cleanup.

receive, not recieve

add missing   #include "opt_kgdb.h"

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.

Sync with head (for UBC+NFS fixes, mostly).

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.

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.

Pullup 1.12 [msaitoh]:
fix error handing in getc
We can handle BREAK signal and framing error correctly.

Adapt to new line discipline scheme.

- fix error handing in getc.
  Now we can handle BREAK signal and framing error correctly.

- cleanup.

Pull up revision 1.11 (approved by thorpej):

 fix old callout interface to new callout interface (callout_reset())

callout()->callout_reset()

Sync w/ netbsd-1-5-base.

clear the ER bit of the SCSSR2 reg.
(This bit isn't cleared automatically)

fix the sci[f]cninit() bugs to work both SCI and SCIF at the same time.

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.

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)

implement send/recieve break signal routines

Pull up to last week's -current.

- unset RS/CS flow control bit from default setting
- GC

add some comments.

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).
