02f2e93b60 - 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.

0de89efe5c 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...

ce834215a7 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.

f4863d1a23 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.

0ddf9be1f0 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.

b3e24f9ce9 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.

0ea3482342 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.

8e6b01171e 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.

17ee9d00bc Next syscons update (given up on numbering :)
Removed screensavers from syscons, they are now LKM's. This makes it
possible to do some really "interesting" screensavers...
Fixed bug that sometimes caused garbage to appear when leaving
"scroll-lock" history.
Reformattet indentation, it got too deep for a normal 80 pos screen.
Split up in syscons.c & syscons.h for use with the saver-lkm's.
Temporarily removed -s option from vidcontrol, savers should now
be loaded with modload.
