MFtbemd:

Use MACHINE_CPUARCH in preference to MACHINE_ARCH. The former is the
source code location of the machine, the latter the binary output. In
general, we want to use MACHINE_CPUARCH instead of MACHINE_ARCH unless
we're tesitng for a specific target. The isn't even moot for
i386/amd64 where there's momemntum towards a MACHINE_CPUARCH == x86,
although a specific cleanup for that likely would be needed...

Correct beastie_saver module name.

Reconnect the old Beastie logo_saver to build as beastie_saver.

Copy logo_saver module to beastie_saver.

Build blank_saver.ko, fade_saver.ko and green_saver.ko on sparc64
now that they work with creator(4) and machfb(4).

Obtained from: FreeBSD(98) 4.0R-Rev01

All the screen savers other than "apm" build on the Alpha. daemon.ko has
been tested to work.

Pull in sys/conf/kmod.mk, rather than /usr/share/mk/bsd.kmod.mk.
This means that the kernel can be totally self contained now and is not
dependent on the last buildworld to update /usr/share/mk. This might
also make it easier to build 5.x kernels on 4.0 boxes etc, assuming
gensetdefs and config(8) are updated.

Add $FreeBSD$

More machdep/random.h -> sys/random.h fixes.

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.

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.

Clean up and reorder.

$Id$ -> $FreeBSD$

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.

MFS: indent-assisted style cleanup.

Retrun EAGAIN if the current video mode is a graphics mode.

Move the definition of set_origin from logo_saver.c to saver.h.

The first stage of console driver reorganization: activate new
keyboard and video card drivers.

Because of the changes, you are required to update your kernel
configuration file now!

The files in sys/dev/syscons are still i386-specific (but less so than
before), and won't compile for alpha and PC98 yet.

syscons still directly accesses the video card registers here and
there; this will be rectified in the later stages.

Add VESA support to syscons.

Kazu writes:

The VESA support code requires vm86 support. Make sure your kernel
configuration file has the following line.
options "VM86"
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.

Submitted by: Kazutaka YOKOTA yokota@FreeBSD.ORG

The daemon, snake and star savers should refuse to load if the current
video mode is the VESA mode, because they cannot work properly under the
VESA mode support as in the current form.

Don't put a path to "sys" in ${CFLAGS} here. bsd.kmod.mk now handles
this more generally.

Include <machine/pc/display.h>, not <i386/include/pc/display.h>. This is
not quite correct, because the Makefiles in lkm/syscons don't set up the
`machine' symlink, but other, more volatile headers in <machine> are
already used.

- The daemon might go off the screen and crashed the system if the
screen size was changed while the screen saver was inactive. Adjust
the positions of the daemon and the text and clip them accordingly
each time.

- Don't call set_border() too often. Some video chip may produce
flicker.

Pointed out by tony@dell.com

- Don't fill the entire screen with blank char every time the saver is
called. Blank only the part of the screen where the daemon and the
text was previously printed.

Make the blank screen saver work with MDA and CGA. The fade and green
savers are also modified so that they behave in the same way as the
blank saver on MDA and CGA, although it's not the way these screen
savers are supposed to work, but fading monitor and tickling green
monitor cannot be done on MDA and CGA, AFAIK. So, this is the second
best solution.

As of this change, the current state of support of screen savers is
summarized in the following table.

MDA CGA EGA VGA
blank OK OK NA OK
daemon OK OK OK OK
fade * * NA OK
green * * NA OK
snake OK OK OK OK
star OK OK OK OK

OK: works
NA: doesn't work, the module cannot be loaded for this adapter.
*: behave the same way as the blank saver.

As you can see, EGA is left out for now. But, we can do no better, as
EGA registers cannot be read...

Incorporated lots of fixes and suggestions from Bruce and changes to
facilitate the new saver loading/unloading notification interface
in syscons.

daemon_saver:
- M_NOWAIT was wrong, since NULL returns are not handled. Just use
M_WAITOK.
- use `ostype' instead of hard-coded "FreeBSD". Now there is no more
hard-coded string! (But, who will run this screen saver on other
OS?!)
- put macros and data declarations in a consistent order.
- -DDEAMON_ONLY and -DSHOW_HOSTNAME options added in the previous commit
are removed. Options of this kind can go stale and no one notices
because no one uses them. DEAMON_ONLY is just removed. SHOW_HOSTNAME
is made default.

snake_saver:
- use `ostype' and `osrelease' as in the daemon saver. The string changes
slightly - there was a hyphen after "FreeBSD"; now there is a space.
(It is consistent with uname -a, like the daemon server already is.)

all screen savers:
- Use the new add_scrn_saver()/remove_scrn_saver() in syscons.c
to declare loading/unloading of a screen saver. Removed reference
to `current_saver' and the variable `old_saver' as they are not
necessary anymore.
- The blank, fade and green screen savers manipulate VGA registers.
Module loading should fail for non-VGA cards.
- `scrn_blanked' is consistently treated as a number/counter rather
than boolean.
- Some savers touch `scp->start' and `scp->end' to force entire screen
update when stopping themselves. This is unnecessary now because
syscons.c takes care of that.
- cleared up many unused or unnecessary #include statements.
- Removed -DLKM from Makefiles.

YOU NEED TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THIS CHANGE.

Take the OS release string from the kernel variable `osrelease'
rather than hard-code it in the message text. Optinally include
the host name in the message if SHOW_HOSTNAME is defined.

Also fixed some `extern' declarations in saver.h.

Make MOD_* macros almost consistent:

Use the name argument almost the same in all LKM types. Maintain
the current behavior for the external (e.g., modstat) name for DEV,
EXEC, and MISC types being #name ## "_mod" and SYCALL and VFS only
#name. This is a candidate for change and I vote just the name without
the "_mod".

Change the DISPATCH macro to MOD_DISPATCH for consistency with the
other macros.

Add an LKM_ANON #define to eliminate the magic -1 and associated
signed/unsigned warnings.

Add MOD_PRIVATE to support wcd.c's poking around in the lkm structure.

Change source in tree to use the new interface.

delete unused variable BINDIR, use new variable MODLOAD/MODUNLOAD

add forgotten $Id$

Added or restored #include of <machine/md_var.h>. Some declarations
moved from <machine/cpufunc.h> to better places.

Delete obnoxious uprintf()s in load/unload procedures.

Changed the first (name) arg of MOD_DEV(), MOD_EXEC() and MOD_MISC()
from a string to an identifier so that it can be used to generate
declarations and strings. It's much easier to stringize an identifier
than to identifize a string. A uniform naming scheme must be used
for the automatically generated things to apply. This is a feature.

Used the module identifer to generate prototypes for the module load,
unload and stat functions. Removed the few prototypes for these that
already existed.

Used the module identifier to generate a unique struct tag in MOD_DEV().
This should probably be done for all the MOD_*() macros.

Moved the trailing semicolon from the MOD_*() macro definitions to the
macro invocations that didn't already (bogusly) have it.

Staticized the module load and unload functions.

Added function return types for the module load, unload and stat functions.

lkm/ibcs2/ibcs2.c:
Included <sys/sysproto.h> to get everything prototyped.
Cleaned up #includes.

lkm/ibcs2/ipfw.c:
Cleaned up #includes.

lkm/linux/linux.c:
The module name had to change from "linux_emulator" to "linux_mod" to
be automatically generated.
Cleaned up #includes.

lkm/syscons/*/*_saver.c:
Completed delcarations of function pointers.

sys/i386/isa/atapi.c:
The module name had to change from "atapi" to "atapi_mod" to be
automatically generated.

sys/i386/isa/wcd.c:
Used the fixed MOD_DEV(). This module has two devices and expanded the
macro in the source instead of fixing it.
The module names had to change from "wcd" and "rwcd" to "wcd_mod" and
"rwcd_mod" to be automatically generated.

sys/pccard/pcic.c:
The module name had to change from "pcic" to "pcic_mod" to be
automatically generated.

Replaced nosys() by lkm_nullcmd(). Always call lkm load/unload/stat
functions instead of skipping the call if the function is nosys().
nosys() returned the wrong value as well as having the wrong type.

Do a pass over the broken LKM's and update them to use the "new"
convention of having their entry point named "<modname>_mod"".
Symorder is enforcing this when the current bsd.kmod.mk is installed.

I've not tested all these, but at least they all compile now.

Reattach them to the makefile.

Note that the change that I made to symorder needs to be compiled and
installed before any LKM's will work - the last version was corrupting
the relocation tables. A "make world" will to this, but if you
manually run a make on the lkm's you'll need to take care of it by
hand.

Update the version in the snake saver...
Something similar needs to happen to RELENG_2_1_0 - or better yet, this
should become dynamic...

Remove trailing whitespace.
