472a4993b0 Add the apm_saver syscons screen saver module.
apm_saver uses the apm_display() routine from the apm system to
"suspend" the "display" part of the machine.

This is beneficial for some laptops (or other machines with
non-traditional displays) that choke on the 'green' saver's
effect.

Another way of looking at this is that it's the same as a screen
saver that does an 'apm -d 0' to blank the display and an 'apm -d 1'
to bring it back. One probably ought to use these commands to make
sure the effect will be correct before using it unattended.

ae8e1d08d7 This patch clears the way for removing a number of tty related
fields in struct cdevsw:

        d_stop          moved to struct tty.
        d_reset         already unused.
        d_devtotty      linkage now provided by dev_t->si_tty.

These fields will be removed from struct cdevsw together with
d_params and d_maxio Real Soon Now.

The changes in this patch consist of:

        initialize dev->si_tty in *_open()
        initialize tty->t_stop
        remove devtotty functions
        rename ttpoll to ttypoll
        a few adjustments to these changes in the generic code
        a bump of __FreeBSD_version
        add a couple of FreeBSD tags

8c12242c81 - Hang the scr_stat struct from dev_t.
- Remove sc_get_scr_stat().  It's not necessary anymore.
- Call ttymalloc() to allocate the struct tty for each vty, rather than
  statically declaring an array of struct tty.  We still need a statically
  allocated struct tty for the first vty which is used for the kernel
  console I/O, though.
- Likewise, call ttymalloc() for /dev/sysmouse and /dev/consolectl.
- Delete unnecessary test on the pointer struct tty *tp in some functions.
- Delete unused code in scmouse.c.

WARNING: this change requires you to recompile screen savers!

9dcbe2404a Convert DEVFS hooks in (most) drivers to make_dev().
Diskslice/label code not yet handled.

Vinum, i4b, alpha, pc98 not dealt with (left to respective Maintainers)

Add the correct hook for devfs to kern_conf.c

The net result of this excercise is that a lot less files depends on DEVFS,
and devtoname() gets more sensible output in many cases.

A few drivers had minor additional cleanups performed relating to cdevsw
registration.

A few drivers don't register a cdevsw{} anymore, but only use make_dev().

6e8394b8ba The second phase of syscons reorganization.
- Split syscons source code into manageable chunks and reorganize
  some of complicated functions.

- Many static variables are moved to the softc structure.

- Added a new key function, PREV.  When this key is pressed, the vty
  immediately before the current vty will become foreground.  Analogue
  to PREV, which is usually assigned to the PrntScrn key.
  PR: kern/10113
  Submitted by: Christian Weisgerber <naddy@mips.rhein-neckar.de>

- Modified the kernel console input function sccngetc() so that it
  handles function keys properly.

- Reorganized the screen update routine.

- VT switching code is reorganized.  It now should be slightly more
  robust than before.

- Added the DEVICE_RESUME function so that syscons no longer hooks the
  APM resume event directly.

- New kernel configuration options: SC_NO_CUTPASTE, SC_NO_FONT_LOADING,
  SC_NO_HISTORY and SC_NO_SYSMOUSE.
  Various parts of syscons can be omitted so that the kernel size is
  reduced.

  SC_PIXEL_MODE
  Made the VESA 800x600 mode an option, rather than a standard part of
  syscons.

  SC_DISABLE_DDBKEY
  Disables the `debug' key combination.

  SC_ALT_MOUSE_IMAGE
  Inverse the character cell at the mouse cursor position in the text
  console, rather than drawing an arrow on the screen.

  SC_DFLT_FONT
  makeoptions "SC_DFLT_FONT=_font_name_"
  Include the named font as the default font of syscons.  16-line,
  14-line and 8-line font data will be compiled in.  This option replaces
  the existing STD8X16FONT option, which loads 16-line font data only.

- The VGA driver is split into /sys/dev/fb/vga.c and /sys/isa/vga_isa.c.

- The video driver provides a set of ioctl commands to manipulate the
  frame buffer.

- New kernel configuration option: VGA_WIDTH90
  Enables 90 column modes: 90x25, 90x30, 90x43, 90x50, 90x60.  These
  modes are mot always supported by the video card.

- The header file machine/console.h is reorganized; its contents is now
  split into sys/fbio.h, sys/kbio.h (a new file) and sys/consio.h
  (another new file).  machine/console.h is still maintained for
  compatibility reasons.

- Kernel console selection/installation routines are fixed and
  slightly rebumped so that it should now be possible to switch between
  the interanl kernel console (sc or vt) and a remote kernel console
  (sio) again, as it was in 2.x, 3.0 and 3.1.

- Screen savers and splash screen decoders
  Because of the header file reorganization described above, screen
  savers and splash screen decoders are slightly modified.  After this
  update, /sys/modules/syscons/saver.h is no longer necessary and is
  removed.

2447bec829 Simplify cdevsw registration.
The cdevsw_add() function now finds the major number(s) in the
struct cdevsw passed to it.  cdevsw_add_generic() is no longer
needed, cdevsw_add() does the same thing.

cdevsw_add() will print an message if the d_maj field looks bogus.

Remove nblkdev and nchrdev variables.  Most places they were used
bogusly.  Instead check a dev_t for validity by seeing if devsw()
or bdevsw() returns NULL.

Move bdevsw() and devsw() functions to kern/kern_conf.c

Bump __FreeBSD_version to 400006

This commit removes:
        72 bogus makedev() calls
        26 bogus SYSINIT functions

if_xe.c bogusly accessed cdevsw[], author/maintainer please fix.

same consistent format.  Please keep it that way.

as an exercise for Bruce.

6182fdbda8 Bring the 'new-bus' to the i386. This extensively changes the way the
i386 platform boots, it is no longer ISA-centric, and is fully dynamic.
Most old drivers compile and run without modification via 'compatability
shims' to enable a smoother transition.  eisa, isapnp and pccard* are
not yet using the new resource manager.  Once fully converted, all drivers
will be loadable, including PCI and ISA.

(Some other changes appear to have snuck in, including a port of Soren's
 ATA driver to the Alpha.  Soren, back this out if you need to.)

This is a checkpoint of work-in-progress, but is quite functional.

The bulk of the work was done over the last few years by Doug Rabson and
Garrett Wollman.

e9deda23ae Keyboard driver update in preparation for the USB keyboard driver.
- Refined internal interface in keyboard drivers so that:
  1. the side effect of device probe is kept minimal,
  2. polling mode function is added,
  3. and new ioctl and configuration options are added (see below).

- Added new ioctl: KDSETREPEAT
  Set keyboard typematic rate.  There has existed an ioctl command,
  KDSETRAD, for the same purpose.  However, KDSETRAD is dependent on
  the AT keyboard.  KDSETREPEAT provides more generic interface.
  KDSETRAD will still be supported in the atkbd driver.

- Added new configuration options:
  ATKBD_DFLT_KEYMAP
  Specify a keymap to be used as the default, built-in keymap.
  (There has been undocumented options, DKKEYMAP, UKKEYMAP, GRKEYMAP,
  SWKEYMAP, RUKEYMAP, ESKEYMAP, and ISKEYMAP to set the default keymap.
  These options are now gone for good.  The new option is more general.)

  KBD_DISABLE_KEYMAP_LOADING
  Don't allow the user to change the keymap.
