o Add two new ioctl's KBADDKBD and KBRELKBD. These are used to add and remove
keyboard to (and from) kbdmux(4) keyboard multiplexer;
o Introduce new kbd_find_keyboard2() function. It does exactly the same job
as kbd_find_keyboard() function except it allows to specify starting index.
This function can be used to iterate over keyboards array;
o Re-implement kbd_find_keyboard() as call to kbd_find_keyboard2() with starting
index of zero;
o Make sure syscons(4) passed KBADDKBD and KBRELKBD ioctl's onto currently
active keyboard.
These changes should not have any visible effect.

function pointer to the vga render dispatch table and initialized it with
vga_nop. The problem is that vga_nop() is a varargs function, and the
table declares a non-varargs function pointer. On amd64 (and I think ppc),
mixing varargs and non-varargs function pointers is fatal.
Change vga_nop() and gfb_nop() from varargs to non-varargs do-nothing
functions. This stops the stack corruption that only happened on amd64.

24, and 32 bit modes. To use that, syscons(4) must be built with
the compile time option 'options SC_PIXEL_MODE', and VESA support (a.k.a.
vesa.ko) must be either loaded, or be compiled into the kernel.
Do not return EINVAL when the mouse state is changed to what it already is,
which seems to cause problems when you have two mice attached, and
applications are not likely obtain useful information through the EINVAL
caused by showing the mouse pointer twice.
Teach vidcontrol(8) about mode names like MODE_<NUMBER>, where <NUMBER> is

syscons(4) and its pseudo-devices don't get confused (including by
other device drivers) with the system controller devices which are

which doesn't assume a hardware cursor on __sparc64__ rather than on
DEV_CREATOR. If we want to include more than one framebuffer driver in
e.g. the GENERIC kernel all drivers have to work the same way. Now that
DEV_CREATOR is no longer used remove it from options.sparc64.

Both the ".init" and the current settings are initialized allowing
the function to be used both at attach and open time.
The function takes an argument to decide if echoing should be enabled.
Echoing should not be enabled for regular physical serial ports
unless they are consoles, in which case they should be configured
by ttyconsolemode() instead.

want a splash screen.
There seems to be some confusion in the syscons code as to the meaning of
the SC_KERNEL_CONSOLE flag. Its absence is sometimes interpreted to mean
"I am not the system console", and sometimes to mean "I am not the only
VGA console" (see the font loading code for an example of the latter).
Someone with better syscons fu than myself should take a closer look.
future:
rename ttyopen() -> tty_open() and ttyclose() -> tty_close().
We need the ttyopen() and ttyclose() for the new generic cdevsw
functions for tty devices in order to have consistent naming.

A number of modules return EINVAL in this instance, and I have left
those alone for now and instead taught MOD_QUIESCE to accept this

it's in the way even more. Basicly: remove all alpha specific console
support from gfb(4), sio(4) and syscons(4). Rewrite the alpha console
initialization to be identical to all other platforms. In a nutshell:
call cninit().
The platform specific code now only sets or clears RB_SERIAL and thus
automaticly causes the right console to be selected.
sio.c:
o Replace the remote GDB hacks and use the GDB debug port interface
instead.
o Make debugging code conditional upon KDB instead of DDB.
o Call kdb_alt_break() instead of db_alt_break().
o Call kdb_enter() instead of breakpoint().
o Remove the ugly compatibility of using the console as the debug
port.
The big lines are:
NODEV -> NULL
NOUDEV -> NODEV
udev_t -> dev_t
udev2dev() -> findcdev()
Various minor adjustments including handling of userland access to kernel
space struct cdev etc.
on architectures that need to call cninit() before the machine is
ready to support mutexes (required by make_dev()).
- Remove make_dev() call from scinit() when flags indicate
unit is the system console, rely on sc_attach_unit() to
handle it.
- When trying to access current screen's status (scr_stat
structure) use the static one provided for the initial
system console if no dev_t is available.
- When calling make_dev() in sc_attach_unit() catch special
case of system's initial console and set up dev_t structure
to include pointer to console's scr_stat struct.
