TAB/space/indent cleanup.

Use explicit struct to represent RX queue buffer data structure.

No binary change.

Maybe the similar change should be applied to MI com(4) and zsc(4)?

Refactor and cleanup sio (uPD7201) drivers.

- remove confusing syscn*() functions (and its header) and prepare
  explicit siottycninit(), siottycnget() and siottycnput() functions
- use exported struct consdev and cn_tab to initialize siotty console
- enable and handle E/S interrupts to make BREAK signal detected properly
- make CSR (status regsiters) access functions inline static
- make single byte read/write (i.e. cnputc() and cngetc()) functions
  static inline and take struct sio_register rather than sio channel
- use proper integer type (uint16_t) for getsiocsr() as siotty.c
- handle channel dependent CR2A and CR2B registers properly
- use more explicit definitions for RR_* macro used by getsiocsr()
- define and use proper RR0 (read register) values
  (there is no isStatusReg(r) macro used on 4.4BSD/luna68k)

Tested on LUNA with both wscons console and serial console.

Fix several styles and formats.

Use C99 designated initializer.

Use proper macro for device register addresses.

Sync w/ HEAD.

Make local functions static.

Mostly merge changes from HEAD upto 20200411

in many device attach paths, allocate memory with KM_SLEEP instead of KM_NOSLEEP
and remove code to handle failures that can no longer happen.

Misc KNF.

update from HEAD

Sync with HEAD

- move prototypes to common header file
- rename function to avoid confusion with pseudo-device attach

include "ioconf.h" to get the 'void <driver>attach(int count);' prototype.

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.

Minor KNF.  No binary changes.

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.

Misc cleanup of sio drivers.

- register softc of child devices as an argument of the sio interrupt
  handler to avoid device_lookup_private() calls on every interrupt
- change type of sc_reg from (void *) to (struct sioreg *)
  to avoid weird address offset calculations with redundant casts
- rename struct sio_softc members for consistency
- use a channel number passed via sio_attach_args in lunaws_attach()

No functional chnages.  Tested on LUNA.

struct device * -> device_t, use device_xname()  (from chs@)
Whitespace cleanup.
Use softint(9) to pass received data into wskbd(9) and wsmouse(9) layers.
It might be problematic to call them from an interrupt handler at IPL_SERIAL.
Tab/space cleanup.
Use softint(9) properly to process TX/RX data between tty(4) layer.
It could cause possible locking issue to call tty(4) layer functions
from IPL_SERIAL interrupt handlers.
Changes details (mostly similar to com(4) and z8530tty(4)):
 - allocate RX buffer and put data and status into it in the interrupt handler
 - call t_linesw->l_rint from the software interrupt handler
 - set the only first byte in siottystart() and use t_outq buffer to send
   multiple TX data
 - call the next t_linesw->l_start on TX complete in the software interrupt
   handler
Also put more changes:
 - handle cnmagic(9) properly (now entering ddb(4) by console BREAK works)
 - allocate tty in the attach function as other drivers rather than first open
 - use proper variable types
Remove initialization of unused t_softc in struct tty (to make pullup easier).

Reorganize IPL for devices.

KNF, use uintNN_t, tab/space cosmetics etc.

bcopy -> memcpy

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.

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.)

Remove all the __P() from sys (excluding sys/dist)
Diff checked with grep and MK1 eyeball.
i386 and amd64 GENERIC and sys still build.

Constify the speedtab arrays

Initialize the two new members of consdev (cn_halt, cn_flush) to NULL so
that this compiles again.

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().

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.

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

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.

file siotty.c was added on branch nathanw_sa on 2002-04-01 07:40:45 +0000

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.

Remove unnecessary test of tp->t_linesw against NULL; they are results
of confusion while correcting compilation error after t_line is
replaced with t_linesw.

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.

file siotty.c was added on branch thorpej_scsipi on 2000-11-20 20:10:26 +0000

Fix a minor typo in the previous change of tp->t_linesw introduction.

Adapt to new line discipline scheme.

- Implement cnbell() -- ring the console bell.  The cn_bell entrypoint
  is optional.
- Add cn_bell to statically allocated consdevs as appropriate.

Put a comment about BREAK detection; DDB fails to resume.  Need to clear
the condition before resume?

- Make SCSI work; by kludges of machine/bus.h. TEAC streamer tape drive
found to be tweaked.  Need extensive verifications.
- Add wsmouse node under ws; not useful this moment.

Introduce NetBSD/luna68k port into CVS repository.
