ddb/db_active.h: New home for extern db_active.

This can be included unconditionally, and db_active can then be
queried unconditionally; if DDB is not in the kernel, then db_active
is a constant zero.  Reduces need for #include opt_ddb.h, #ifdef DDB.

Remove unused extern declaration of constty.

fix various typos, mainly in comments, but also in man pages and log messages.

Restore all work from the former pgoyette-localcount branch (which is
now abandoned doe to cvs merge botch).

The branch now builds, and installs via anita.  There are still some
problems (cgd is non-functional and all atf tests time-out) but they
will get resolved soon.

Adapt the machine/arch dependent code to the new {b,c}devsw reference
counting.

XXX Most of these will require testing by someone other than myself, as
I have a limited selection of hardware!

Instead of repeatedly typing the conditional initialization of the
.d_localcount members in the various {b,c}devsw, define an initializer
macro and use it.  This also removes the need for defining new symbols
for each 'struct localcount'.

As suggested by riastradh@

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.

sync with head.

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")

sync with head

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.

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

Use CFATTACH_DECL().

. treat a stream of framing errors as a single break
. trigger ddb upon receiving a break if we are the console

Declare all cfattach structures const.

remove trailing \n in panic().  approved perry.

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.

catch up with -current on kqueue branch

Add the character device switch.
Replace the direct-access to devsw table with calling devsw API.

Catch up to -current.
(CVS: It's not just a program. It's an adventure!)

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.

Catch up to -current.

add __KERNEL_RCSID as suggested by Luke Mewburn

make sure we have CLOCAL set and HUPCL unset when the serial port is used as
a console.

Sync kqueue branch with -current.

Sync the thorpej-mips-cache branch with -current.

file ser.c was added on branch nathanw_sa on 2002-02-28 04:06:59 +0000

defopt SERCONSOLE

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.

Catch up to -current.

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).

Make these compile again, plus minor aesthetic changes.

Sync with HEAD.

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.

I updated the amiga SCSI drivers, but completely untested yet (may not even
compile)

Adapt to new line discipline scheme.

Fix thinko in fix for fix for cf_unit abuse.

Make this work again after the last changes...
remember, folks, potential Amiga console devices run autoconfiguration
_twice_.

Prevent serial port from hanging when used as both console and terminal.

Kill more broken cf_unit bogons.

Back out previous change. It breaks Seyon in a non-obvious way.

Precompute lots of bitmasks etc. in serparam(). Results in slightly better
(but I suspect, insignificant) performance, and also prepares for 8bit +
parity support.

The INTF_RBF bit of INTREQ is mirrored in SERDAT. As we would read this
register anyway when the bit is set, we can safe one of the (slow) custom
chip accesses by using this bit.
Sounds ridiculous, but at a hardware FIFO depth of 1 and ~1 usec per
access (at IPL 5) it might help the highspeed addicts.

Synchronize shadow ciab.pra variable on first open.

Fix a problem with bogus hangups that Thorsten Frueauf has reported.

Make ser.c compile again (preliminary release). It needs still a lot of
cleanup, but at least mainstream usage should be possible again (worked
for me 5 minutes ago).

Adjust for changes to config.

Update marc-pcmcia branch from trunk.

Use a global variable to hold the current speed of the internal serial port.
This will be used by certain SCSI drivers to limit the length of DMA transfers
when the serial port is running at higher speeds.  GVP and Phase5 DMA
interfers significantly with CPU execution, and significantly increases
receive buffer overruns (silo overflow).  Reducing the DMA transfer length
can reduce the overruns.

Update marc-pcmcia branch from trunk.

Deal with HUPCL, closing (but in a different way than proposed) PR 1010.

Read the received data register before clearing the RBF interrupt.  Clearing
RBF appears to also clear the OVRUN bit in the receive data, resulting in
the loss of of overflow status.

Get rid of __BROKEN_INDIRECT_CONFIG.

backout previous kprintf change

printf -> kprintf, sprintf -> ksprintf

tty stop functions really should return void, not int, and certainly not both.

Pull up from trunk:
> Add tty_attach() calls for pstat -t.  Closes PR #2519

Add tty_attach() calls for pstat -t.  Closes PR #2519

Make the compiler happy if you make a kernel with -Wall

Two fixes:
- add a missing splser()/splx() pair in ser.c. Without it, we used to
  drop incoming characters under heavy load.
- delete the entries for 50 and 75 bps from the serspeedtab, as our
  hardware doesn't support these speeds.

Protect two critical lines of ser.c with splser(). Without this, a
race condition exists which makes the internal serial drop incoming
characters under heavy load.

Changed the speed calculations of the Amiga-builtin-serial driver to
allow any baudrate the hardware allows, and to forbid two baudrates
(50 and 75) which the hardware does NOT support but which the old
speed conversion table pretended to support.

- Cleanup for -Wall and -Wstrict-prototypes
- Added support for multiple floppy drives
- CyberVision64:
        - has now a real console mode
        - another bugfix for boards with the new S3 chip
- Ariadne:
        - fixed crashes with aeput (mbuf failure)

Clean up typos and other errors from new device attachment changes.

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.

sys/arch/amiga tree. This is the machdep part required to get the kernel
up on an A3000. There are still (very) few changes required outside the
arch/amiga tree, so you can't recompile the kernel yet. Support for
third party SCSI controllers for the A2000 is on its way. The kernel is
fully functional (except for a missing ethernet-driver ...). This
tree is based on my version #390.
