cad4243e61 The PnP code in 2.2.6 detects the Motorola ModemSurfer 56K,
but doesn't do much of anything with it.  I added it to siopnp_ids[]
and it was found and recognized as a serial port.

db37f632a0 close() is no longer a SLICE method.
Close is simply an open with no-read and no-write once internal to SLICE

0796a5c56e Add changes and code to implement a functional DEVFS.
This code will be turned on with the TWO options
DEVFS and SLICE. (see LINT)
Two labels PRE_DEVFS_SLICE and POST_DEVFS_SLICE will deliniate these changes.

/dev will be automatically mounted by init (thanks phk)
on bootup. See /sys/dev/slice/slice.4 for more info.
All code should act the same without these options enabled.

Mike Smith, Poul Henning Kamp, Soeren, and a few dozen others

This code does not support the following:
bad144 handling.
Persistance. (My head is still hurting from the last time we discussed this)
ATAPI flopies are not handled by the SLICE code yet.

When this code is running, all major numbers are arbitrary and COULD
be dynamically assigned. (this is not done, for POLA only)
Minor numbers for disk slices ARE arbitray and dynamically assigned.

f11d6ec503 More fixes to deal with fonts:
- Set the correct value scp->font_size in init_scp().
- Set scp->font_size to FONT_NONE for VGA_MODEX.

Interim fix for a font problem:
- A kludge to display the correct font on some video cards.
  We should be able to load multiple fonts to the VGA plane #2 and switch
  between fonts by setting the font select register in the VGA sequencer.
  It appears that the current code isn't functioning as expected on
  some VGA cards (I have reports on Millenium and Mach64 cards).  This is
  either a bug in syscons or a hardware compatibility problem ;-<
  This kludge will always load only one font set at a time and always use
  the font page #0 on the plane #2.  It is an interim kludge until
  we find the exact cause and solution.

Small adjustment for mouse cursor handling:
- Turn off the mouse cursor early when changing video modes.

Video mode switch fixes:
- Stop the screen saver when changing video modes.
- Enclose the critical section with a pair of spltty()/splx().
- A kludge to prevent scrn_update() from accessing video memory in less-
  critical sections in video mode change; artificially turn on the
  UNKNOWN_MODE flag.

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.

c0758a12df Update timer0_prescaler_count before calling hardclock() while timer0
is "acquired".  This fixes a TSC biasing error of about 10 msec when
pcaudio is active.

Update `time' before calling hardclock() when timer0 is being released.
This is not known to be important.

Added some delays in writertc().  Efficiency is not critical here, unlike
in rtcin(), and we already use conservative delays there.

Don't touch the hardware when machdep.i8254_freq is being changed but
the maximum count wouldn't change.  This fixes jitter of up to 10 msec
for most small adjustments to machdep.i8254_freq.  When the maximum
count needs to change, the hardware should be adjusted more carefully.

e19355cd15 Add support for VESA mode 0x102 (800x600x4) in syscons. You can activate
this using option "-b" to the boot blocks.  It is smartest to compile
a font into your kernel (See LINT), but not mandatory, but apart from
the cursor you will see nothing on the screen until you load a font.

This mode allows XF86_VGA16 to run in 800x600 mode on otherwise unsupported
graphics hardware.

A number of buglets in the cursor handling in syscons may become
visible this way.

34f61944a9 - Move the mouse cursor to the center of the screen after video
mode switch in ioctl.
Possibly related to PR: kern/4271

- A kludge: initialize scp->xpixel and ypixel even in the text mode.
If the console enters the `unknown' graphics mode via the ioctl KDSETMODE
(KD_GRAPHICS), these fields are not set (because syscons cannot know
the correct values), but set_mouse_pos() need to refer to these field
to adjust the mouse position.

- Turn off MOUSE_VISIBLE when switching video mode by ioctl.

- another new option: SC_MOUSE_CHAR
Define the first character code of four consecutive codes to be used for
the mouse cursor.  Default codes are 0xd0 through 0xd3.  Beware that
if you decide to use any codes outside the range of 0xc0-0xdf,
the mouse cursor may not look good, because of the way VGA displays
characters in 9-dot-wide character cells.
Requested by several people.

(This patch was tested by a person who recently reported, in the -current
ML, a page fault problem in the kernel (draw_mouse_iamge()) after
X server shutdown. The patch cured his problem.)

3ed12c01d2 Added accent (dead) key support to syscons and kbdcontrol.
With a keymap with accent key definitions loaded to syscons, you press
an accent key followed by a regular letter key to produce an accented
letter.  Press an accent key followed by the space bar to get the
accent letter itself.

Code is based on the ideas and work by jmrueda@diatel.upm.es and
totii@est.is.

PR: i386/4016

- Defined structures and constants for accent (dead) keys.

syscons.c, kbdtables.h
- When an accent key is pressed, set the corresponding index to
  `accents'.  If the next key is the space key, produce the accent char
  itself.  Otherwise search the accent key map entry, indexed by
  `accents', for a matching pair of a regular char and an accented char.
- Added ioctl functions to set and get the accent key map (PIO_DEADKEYMAP
  and GIO_DEADKEYMAP).
