1) Supports PCI to PCI bridge devices (and tries to initialise them,
even if the BIOS is brain dead).
2) Supports shared PCI interrupts. Interrupt handlers now MUST return
'0' if they found nothing to do, '1' otherwise.
New features tested with i486 systems based on the Intel Saturn and
a DEC 4channel Ethernet card only, but expected to work on most systems.
The option PCI_REMAP has been removed !

a device specific shutdown routine for devconf. Assign the value of this
to the kern_devconf struct. Implement a device shutdown routine for if_de
that disables the device. This will stop the device from corrupting memory
after a reboot.
Let "grey delete" be a function key (default is 0x7f)
Fix the xor cursor again..
Made the backspace key generate del as default
Made CTRL-space generate nul as default.
(a) bring back ttselect, now that we have xxxdevtotty() it isn't dangerous.
(b) remove all of the wrappers that have been replaced by ttselect
(c) fix formatting in syscons.c and definition in syscons.h
(d) add cxdevtotty
NOT DONE:
(e) make pcvt work... it was already broken...when someone fixes pcvt to
link properly, just rename get_pccons to xxxdevtotty and we're done

Test for COMCONSOLE before testing for RB_SERIAL so that the RB_SERIAL

Simplify and Uniformize style of previous commit.
(b) add a function callback vector to tty drivers that will return a pointer

utilities don't crash if NAPM changes (and make the damn kernel compile!)

Please test the slice/label features:
cd /dev; sh MAKEDEV svn0
cd /var/tmp; dd if=/dev/zero of=vnfile bs=8192 count=1024
vnconfig -c /dev/rvn0 /var/tmp/vnfile
fdisk /dev/rvn0 # invent a geometry, create one BSD partition
disklabel -r -w vn0 floppy # a convenient (bogus) label
disklabel -e vn0 # edit label to match device
newfs /dev/rvn0a
mount /dev/vn0a /mnt

The steps after the fdisk could name the device vn0s1 instead of vn0.
PCI BIOS mappings are retained, except if option PCI_REMAP
is specified in the kernel config file.
There is now a list of attach addresses, and the first
address that seems to make some device registers appear
is chosen.

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

briefly over it, and see some serious architectural issues in this stuff.
On the other hand, I doubt that we will have any solution to these issues
before 2.1, so we might as well leave this in.
Most of the stuff is bracketed by #ifdef's so it shouldn't matter too much
in the normal case.

Fix an off by 1 error. Some caclulations seem to be off by a factor
of NCY. NCY defaults to 16, which gives 256 tty structs occupying
0xd000 bytes. The minor number encoding only allows 16 ttys.

It is tested and working for me but probably have some bugs i
didn't noticed so test it and reply...
It can:
look at what's sent to the user from tty device
snoop on pty's,vty's and serial tty's
It (still) can't:
write to tty
see what user types in local echo mode
It is probably bad styled and
very dependant on tty_pty.c,sio.c and syscons.c
I would be really happy if another ppl would make their
changes because i am not sure this is the best snoop
we can have..but it is good..:)))))

case, software cursor now optional case. Driver must provide
raw things (what hardware do for us, exactly) as default case,
all driver features must be _optional_. Modern VGAs have internal
configuration utilities to set cursor shape/blinking which stored
into cards ROM, and syscons nuke out such features completely
by forcing software cursor. Moreover, software cursor is hard
to distinguish on standouted (or near standouted) fields and
tends to disappearse from the screen.
Set "flags 0x4" to enable software cursor now.
o Cleanup screen savers.
o Don't draw cursor if saver or blinker is active.
o Duplicated code moved to functons.
o Add more checks for blinker in progress, character lost otherwise

o Reduce blinking counter to 3, too slow in old variant.
o Fix timeout code in scrn_timer(), old variant can reenter iself,

o Disable visual bell for scroll lock mode, saved screen

Initialize SIMODE1 and SXFRCTL1 from the kernel in ahc_init instead of

Reorder some sections to kill superflous jumps. These optimizations kill

sio.c and sioreg.c changed to allow autodetecting the RB_SERIAL flag
passed by the boot blocks so that the kernel can switch to 'serial
console' mode automagically. 'options COMCONSOLE' can still be specified
to force the kernel to always use the serial port as a console.
CONUNIT and CONADDR can also be specified in the kernel config file
if the user wants to shift the console to a different port.

reimplement WDTR and SDTR optimization to remove code in the sequencer

yeilds the same performance.
properly from the beginning:
1) The `kern_devconf' struct should be a part of the driver's
`softc' structure (now it is).
2) The `description' should say what the device actually is,
rather than just giving a model number (now it does).
3) The device should be registered even if the probe fails, so
that it can be reconfigured later.
4) For netifs, the device state should follow the IFF_UP flag.
Other network interfaces should follow this example. (Please?) Eventually
there should be a rundown routine doing the equivalent of setting IFF_UP
off, and perhaps more if warranted.

correct console number for the VT_WAITACTIVE ioctl. Invalid console numbers

Use bcopyw() instead of move_up() and move_down(). bcopyw() handles
overlapped copies and should be faster. Actually use bcopy(). bcopy()
is slightly faster if video memory is 16-bit and about twice as fast if
it is 32-bit. bcopy() is said to fail on someGA's, but syscons already
depends on it working for other accesses to video memory.
