NFS_*TIMO should possibly be converted to sysctl vars (jkh's suggestion),
but in some cases it looks like nfs keeps a copy of the value in a struct
hash sizes are already ifdef'd KERNEL, so there aren't userland inpact
from them...
Move a.out libraries to /usr/lib/aout to make space for ELF libs.
Make rtld usr /usr/lib/aout as default library path.
Make ldconfig reject /usr/lib as an a.out library path.
Fix various Makefiles for LIBDIR!=/usr/lib breakage.
This will after a make world & reboot give a system that no
longer uses /usr/lib/*, infact one could remove all the old
libraries there, they are not used anymore.
We are getting close to an ELF make world, but I'll let this
all settle for a week or two...
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.
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.
PPP_DEFLATE options... The code uses #if defined(PPP_DEFLATE) etc, so the
original method of "#define PPP_DEFLATE 0" did not actually disable
anything. It was not possible to configure out bsdcomp or zlib
compression. Also, join the settings for PPP_FILTER and NBPFILTER together
since they are related here (can't have PPP_FILTER without NBPFILTER).
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...

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.
rather than hard-code it in the message text. Optinally include
the host name in the message if SHOW_HOSTNAME is defined.
The origianl idea and sample code submitted by Angelo Turetta
<ATuretta@stylo.it>.
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.
