55cafc98c5 Fix longstanding mouse cursor bug: blinking and eating all CPU while near text
cursor.
The reason is: mouse cursor goes into hide/visible loop while text cursor even
not moved.

329292029c The SRM console gets the red and blue attributes backwards in the VGA
palette.  As a result, the colors on the video console can look rather
weird.  For example, sysinstall on the alpha has a read background.  We
can work around this partially by remapping the colors used by syscons for
the ANSI color escape sequences.  Note that screen savers and anything that
sets the colors explicitly will still get incorrect colors, but programs
such as sysinstall will now use the correct colors.  A more correct fix
would be to actually fix the VGA palette on boot by either swapping all
the red and blue attributes or by hardcoding a standard palette and
overwriting the entire palette.

21c3015a24 * Completely rewrite the alpha busspace to hide the implementation from
the drivers.
* Remove legacy inx/outx support from chipset and replace with macros
  which call busspace.
* Rework pci config accesses to route through the pcib device instead of

With these changes it is possible to cleanly support machines which have
more than one independantly numbered PCI busses. As a bonus, the new
busspace implementation should be measurably faster than the old one.

2b944ee2b9 This is the 3rd stage of syscons code reorganization.
- Split terminal emulation code from the main part of the driver so
that we can have alternative terminal emulator modules if we like in
the future.  (We are not quite there yet, though.)

- Put sysmouse related code in a separate file, thus, simplifying the
main part of the driver.

As some files are added to the source tree, you need to run config(8)
before you compile a new kernel next time.

You shouldn't see any functional change by this commit; this is only
internal code reorganization.

b2f564ea70 Add "panic key" function to syscons. When this key is defined in a
keymap and pressed, the system panic will be forced.

This feature must be specifically enabled by a new sysctl variable:
machdep.enable_panic_key.  Its default value is 0.  The panic key
won't do anything unless this variable is set to non-zero.

To use the panic key, add a keyword 'panic' to a key in your
keymap file.  The following example assigns the panic function
to SysReq (Alt-PrintScreen) key (keycode 84).

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.

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.
  Submitted by: Nick Hibma (n_hibma@FreeBSD.ORG)

  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.

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

This commit removes:

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.

- 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.)

If you want to statically link the VESA support code to the kernel,
add the following option to the kernel configuration file.
        options "VESA"

The vidcontrol command now accepts the following video mode names:
VESA_132x25, VESA_132x43, VESA_132x50, VESA_132x60, VESA_800x600

The VESA_800x600 mode is a raster display mode. The 80x25 text will
be displayed on the 800x600 screen. Useful for some laptop computers.

vidcontrol accepts the new `-i <info>' option, where <info> must be
either `adapter' or `mode'.  When the `-i adapter' option is given,
vidcontrol will print basic information (not much) on the video
adapter. When the `-i mode' option is specified, vidcontrol will
list video modes which are actually supported by the video adapter.

saver and splash screen can all work properly with syscons.  Note that
the splash screen option (SC_SPLASH_SCREEN) does not work yet, as it
requires additional code from msmith.

- Delay screen switch in `switch_scr()' until the screen saver is
  stopped, if one is running,
- Start the screen saver immediately, if any, when the `saver' key is
  pressed. (There will be another commit for `kbdcontrol' to support
  this keyword in the keymap file.)
- Do not always stop the screen saver when mouse-related ioctls
  are called.  Stop it only if the mouse is moved or buttons are
  clicked; don't stop it if any other mouse ioctls are called.
