df88297cad Initialize isa_devtab entries for interrupt handlers in individual
device drivers, not in ioconf.c.  Use a different hack in isa_device.h
so that a new config(8) is not required yet.

35fa873125 Added D_TTY to the cdevswitch flags for all tty drivers. This is required
for the Lite2 fix for always returning EIO in dead_read().

Cleaned up the cdevswitch initializers for all tty drivers.

Removed explicit calls to ttsetwater() from all (tty) drivers.  ttsetwater()
is now called centrally for opens, not just for parameter changes.

eba01972cd Correct handling of ASCII DEL (0x7F).
I don't have access to a real VT220 to verify this against.
However, I'm committing the patch in `good faith' because
(a) getting hold of a real VT220 is going to be increasingly difficult
    the longer the PR sits around,
(b) some one was troubled enough to in a PR and
(c) the fix is minor and has no other implications.

1d5f38ac22 This commit fixes various 64bit portability problems required for
FreeBSD/alpha.  The most significant item is to change the command
argument to ioctl functions from int to u_long.  This change brings us
inline with various other BSD versions.  Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.

The prototype FreeBSD/alpha machdep will follow in a couple of days
time.

9b703b1455 Eradicate the variable "time" from the kernel, using various measures.
"time" wasn't a atomic variable, so splfoo() protection were needed
around any access to it, unless you just wanted the seconds part.

Most uses of time.tv_sec now uses the new variable time_second instead.

gettime() changed to getmicrotime(0.

Remove a couple of unneeded splfoo() protections, the new getmicrotime()
is atomic, (until Bruce sets a breakpoint in it).

A couple of places needed random data, so use read_random() instead
of mucking about with time which isn't random.

Add a new nfs_curusec() function.

Mark a couple of bogosities involving the now disappeard time variable.

Update ffs_update() to avoid the weird "== &time" checks, by fixing the
one remaining call that passwd &time as args.

Change profiling in ncr.c to use ticks instead of time.  Resolution is
the same.

Add new function "tvtohz()" to avoid the bogus "splfoo(), add time, call
hzto() which subtracts time" sequences.

e7c3d728c1 Fix the broken VT_WAITACTIVE ioctl for the case where the third arg
was 0.

PR:		4164
Submitted by:	Joe Traister <traister@mojozone.org>

While i was at it, also fixed a broken return value for the VT_RELDISP
ioctl, iff the third arg was legally VT_TRUE, but the destination
screen was in process mode so the actual switch had to be deferred.
This was breaking the ability to directly toggle between two X servers
running on two VTs, since the server getting the bogus error return
was running wild, and competing with the other one for the hardware.
(Sigh, this was a very long-standing bug.)

2d072e5f9d Fixed the type of timeout functions and removed casts that hid the
type mismatches.  There was no problem in practice (at least on 386's).

Don't cast NULL in calls to timeout functions.  pcvt is fully prototyped
and doesn't support K&R.

Timeout functions take args of type `void *', so use magic numbers of
type `void *' for UPDATE_* to reduce the danger of wrong conversions.

Removed FreeBSD-pre-1.1-related TIMEOUT_FUNC_T macro.  It was especially
bogus for the pre-1.1 case.

553a7d9d25 Incorporate kludge/fix from `syscons' ver 1.207 and 1.209.
1) Dell Latitude XPi
This laptop has a strange, IMHO broken :-), keyboard controller which
wouldn't disable the keyboard interrupt. The kludge is to disable tty
intr. during set_keyboard(), used for changing LED and setting
typematic.

The patch also changes the function name:
    set_keyboard() -> set_keyboard_param()
Although it is a static function, the name corrides with a routine in
`syscons' and is confusing when debugging the kernel which has both
`syscons' and `pcvt' with DDB. (Suggested by Bruce)

2) doreset() bug
doreset() failed to preserve some bits in the keyboard controller's
command byte during keyboard reset. This bug may put some keyboard
controllers in old motherboards (386 and 486) in a strange state,
resulting in complete keyboard lockup or random key input.

dafbb728f2 Fix a bogon in pcvt that caused a characterset designation to not take
effect immediately, but required a following (normally redundant) G0
into GL mapping.  This adds one layer of indirection (thus might make it
slower), but fixes the broken box character drawing in pcvt.

Hellmuth and Bruce are unfortunately too busy too review this right now,
but i wanna have it in 2.2 since it has often been asked in the past.

9434a8b4e5 Avoid touching the LEDs too early in the game. After the recent
changes to the keyboard code in pcvt, this update_led() very often
caused pcvt to hang early at boot time.

(Eventually, a better solution should be found, but the simple
omission serves well as a workaround for something that is actually a
show-stopper class problem.)

5a3b6bd7f9 Fixed setting of the keyboard LEDs. For some keyboards and/or keyboard
controllers, it is an error to issue a command before the keyboard
has had time to reply to the previous command.  Setting the LEDs
involves issueing 2 commands, so it never worked on these keyboards.

Fixed resetting of keyboard.  It is possible for unprocessed
scancodes to be present when the reset routine is called.  This
usually occurs after switching from one console driver to another
in userconfig.  pcvt and syscons attempt to flush any stale scancodes,
but sometimes fail to do so because keyboard and/or keyboard
controller takes a long time to send the scancodes after reset
(scancodes are apparently not flushed by reset!).  syscons handles
this later by not checking for errors at strategic places, but pcvt
was confused.

Use an impossible initial and failure mode setting for the LEDs
so that the LEDs always get set if they are possibly out of sync.

Added missing spltty() in update_led().

dcde70f16b Fix two minor oddities introduced by my yesterday's patches:
. preserve a multi-char sequence in a small static buffer inside
  pccngetc(), so it won't be clobbered later (used to happen when
  breaking into DDB user Ctrl-Alt-ESC), and

. simplify the ``keystroke is present'' determination in sgetc(), thus
  making pccncheck() actually working without waiting for a keystroke.

b0b6f5d7b9 Fix many long-standing bugs and problems with pcvt, namely:
. make pccncheck() work even when interrupts are disabled, so the
  ``Press a key on the console...'' procedure will work,
. make kernel colors #ifndef, so they can be overridden from the
  config file,
. use shutdown_nice() instead of cpu_reset() if Ctrl-Alt-Del is
  enabled,
. allow pccngetc() to return more than a single character, so the
  arrow keys will work (and thus visual UserConfig!),
. fix a warning.

This closes all know PRs related to pcvt, in particular #845, #1236,
and #1265.  PR #991 is a duplicate for 845, and PR #1283 has already
been fixed earlier in rev 1.11 of pcvt_conf.h.
