b5b361cb8c Allow syscons to work on amd64 and i386 without any hints:
- Enable keyboard autodetection by default for ISA syscons attachments.
- If there are no syscons hints at all, assume there is a single sc0 device
  anyway.  The console probe will still fail unless a VGA adapter is found.

1d73a9dc74 Further cleanup of sound generation in syscons:
The timer_spkr_*() functions take care of the enabling/disabling
of the speaker.

Test on the existence of timer_spkr_*() functions, rather than
architectures.

e465985885 The "free-lance" timer in the i8254 is only used for the speaker
these days, so de-generalize the acquire_timer/release_timer api
to just deal with speakers.

The new (optional) MD functions are:
	timer_spkr_acquire()
	timer_spkr_release()
and
	timer_spkr_setfreq()

the last of which configures the timer to generate a tone of a given
frequency, in Hz instead of 1/1193182th of seconds.

Drop entirely timer2 on pc98, it is not used anywhere at all.

Move sysbeep() to kern/tty_cons.c and use the timer_spkr*() if
they exist, and do nothing otherwise.

Remove prototypes and empty acquire-/release-timer() and sysbeep()
functions from the non-beeping archs.

This eliminate the need for the speaker driver to know about
i8254frequency at all.  In theory this makes the speaker driver MI,
contingent on the timer_spkr_*() functions existing but the driver
does not know this yet and still attaches to the ISA bus.

Syscons is more tricky, in one function, sc_tone(), it knows the hz
and things are just fine.

In the other function, sc_bell() it seems to get the period from
the KDMKTONE ioctl in terms if 1/1193182th second, so we hardcode
the 1193182 and leave it at that.  It's probably not important.

Change a few other sysbeep() uses which obviously knew that the
argument was in terms of i8254 frequency, and leave alone those
that look like people thought sysbeep() took frequency in hertz.

This eliminates the knowledge of i8254_freq from all but the actual
clock.c code and the prof_machdep.c on amd64 and i386, where I think
it would be smart to ask for help from the timecounters anyway [TBD].

ebfbcd612a Rename timer0_max_count to i8254_max_count.
Rename timer0_real_max_count to i8254_real_max_count and make it static.
Rename timer_freq to i8254_freq and make it a loader tunable.

24072ca35b - Move timerreg.h to <arch>/include and split i8253 specific defines into
i8253reg.h, and add some defines to control a speaker.
- Move PPI related defines from i386/isa/spkr.c into ppireg.h and use them.
- Move IO_{PPI,TIMER} defines into ppireg.h and timerreg.h respectively.
- Use isa/isareg.h rather than <arch>/isa/isa.h.

Tested on: i386, pc98

2169193596 Converge towards i386. I originally resisted creating <machine/pc/bios.h>
because it was mostly irrelevant - except for the silly BIOS_PADDRTOVADDR
etc macros.  Along the way of working around this, I missed a few things.

* Make syscons properly inherit the bios capslock/shiftlock/etc state like
  i386 does.  Note that we cannot inherit the bios key repeat rate because
  that requires a bios call (which is impossible for us).
* Give syscons the ability to beep on amd64.  Oops.

While here, make bios.c compile and add it to files.amd64.

8a9bc9c03b - Use the new resource_disabled() helper function to see if devices are
disabled.
- Change the apm driver to match the acpi driver's behavior by checking to
  see if the device is disabled in the identify routine instead of in the
  probe routine.  This way if the device is disabled it is never created.

Note that a few places (ips(4), Alpha SMP) used "disable" instead of
"disabled" for their hint names, and these hints must be changed to
"disabled".  If this is a big problem, resource_disabled() can always be
changed to honor both names.

81e3fd99fc This is a temporary bandaid to get vidconsole working again without
options USERCONFIG being present.  Due to the lack of early boot hints
neither sio or sc would succeed the console probe.  If USERCONFIG was
active, there was a second cninit() after userconfig had run and that
happened to make the console selection work.  If you left out USERCONFIG,
you would end up with no console at all. :-(

This needs a proper fix, especially when sc looses the "at isa" hint.
But for now, this works.

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.
  PR: i386/7510
  Submitted by: kbyanc@freedomnet.com and alexv@sui.gda.itesm.mx.

- 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.

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.
