6472ac3d8a Mark all SYSCTL_NODEs static that have no corresponding SYSCTL_DECLs.
The SYSCTL_NODE macro defines a list that stores all child-elements of
that node. If there's no SYSCTL_DECL macro anywhere else, there's no
reason why it shouldn't be static.

78d4d8eeb2 Restore binary compatibility for GIO_KEYMAP and PIO_KEYMAP.
Back in 2009 I changed the ABI of the GIO_KEYMAP and PIO_KEYMAP ioctls
to support wide characters. I created a patch to add ABI compatibility
for the old calls, but I didn't get any feedback to that.

It seems now people are upgrading from 8 to 9 they experience this
issue, so add it anyway.

052002e6f2 Use an unsigned integer for storing the key code.
It seems Clang breaks when checking for SPCLKEY, which is now
0x80000000. Using an unsigned integer fixes this. This is also
consistent with other pieces of kbd/syscons code, because these also use
u_int.

b05f9c86d1 Make the keyboard layer Unicode aware.
Just take keyent_t to use an u_int to store the Unicode codepoints.
Unfortunately the keymap is now too big to be loaded using an ioctl
argument, so change the ioctl to pick a pointer.

This change breaks kbdcontrol ABI. It doesn't break X11, because X11
doesn't do anything with syscons keymaps. It just switches the device
out of K_XLATE.

5f46eda1fd Move buffer management into kbd and kbdmux drivers.
These two drivers seem to be the last consumers of clists. clists are
quite overengineered for simple circular buffers, so I'm adding similar
buffer management routines to the kbd and kbdmux drivers. The input
buffer is now part of the softc structures, instead of having
dynamically allocated cblocks.

6bfa9a2d66 Replace all calls to minor() with dev2unit().
After I removed all the unit2minor()/minor2unit() calls from the kernel
yesterday, I realised calling minor() everywhere is quite confusing.
Character devices now only have the ability to store a unit number, not
a minor number. Remove the confusion by using dev2unit() everywhere.

This commit could also be considered as a bug fix. A lot of drivers call
minor(), while they should actually be calling dev2unit(). In -CURRENT
this isn't a problem, but it turns out we never had any problem reports
related to that issue in the past. I suspect not many people connect
more than 256 pieces of the same hardware.

75ec42320d Don't include <sys/tty.h> in non-TTY drivers.
The kbd, kbdmux, ugen and uhid drivers included <sys/tty.h>, because
they needed clists, which have been moved to <sys/clist.h> some time
ago. In the MPSAFE TTY branch, <sys/tty.h> does not include
<sys/clist.h>, which means we have to teach these drivers to include
this header file directly.

implemented with macros. This patch improves code readability. Reasoning
behind kbdd_* is a "keyboard discipline".

List of macros is supposed to be complete--all methods of keyboard_switch

Functionally, this code should be no-op. My intention is to leave current
behaviour of code as is.

d168d95487 Integrate kbdmux(4) into syscons(4) and kbd code.
By default syscons(4) will look for the kbdmux(4) keyboard first, and then,
if not found, look for any keyboard.

Current kbd code is modified so if kbdmux(4) is the current keyboard, all
new keyboards are automatically added to the kbdmux(4).

Switch to kbdmux(4) can be done at boot time, by loading kbdmux module at
the loader prompt, or at runtime, by kldload'ing the kbdmux module and
releasing current active keyboard.

If, for whatever reason, kbdmux(4) is not required/desired then just do
not load it and everything should work as before. It is also possible to
kldunload kbdmux at runtime and syscons(4) will automatically switch to
the first available keyboard.

04551c6ce5 kbdmux(4) keyboard multiplexer integration
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.

520b635320 - Hook up the new locations of the atkbdc(4), atkbd(4) and psm(4) source
files after they were repo-copied to sys/dev/atkbdc. The sources of
  atkbdc(4) and its children were moved to the new location in preparation
  for adding an EBus front-end to atkbdc(4) for use on sparc64; i.e. in
  order to not further scatter them over the whole tree which would have
  been the result of adding atkbdc_ebus.c in e.g. sys/sparc64/ebus. Another
  reason for the repo-copies was that some of the sources were misfiled,
  e.g. sys/isa/atkbd_isa.c wasn't ISA-specific at all but for hanging
  atkbd(4) off of atkbdc(4) and was renamed to atkbd_atkbdc.c accordingly.
  Most of sys/isa/psm.c, i.e. expect for its PSMC PNP part, also isn't
  ISA-specific.
- Separate the parts of atkbdc_isa.c which aren't actually ISA-specific
  but are shareable between different atkbdc(4) bus front-ends into
  atkbdc_subr.c (repo-copied from atkbdc_isa.c). While here use
  bus_generic_rl_alloc_resource() and bus_generic_rl_release_resource()
  respectively in atkbdc_isa.c instead of rolling own versions.
- Add sparc64 MD bits to atkbdc(4) and atkbd(4) and an EBus front-end for
  atkbdc(4). PS/2 controllers and input devices are used on a couple of
  Sun OEM boards and occur on either the EBus or the ISA bus. Depending on
  the board it's either the only on-board mean to connect a keyboard and
  mouse or an alternative to either RS232 or USB devices.
- Wrap the PSMC PNP part of psm.c in #ifdef DEV_ISA so it can be compiled
  without isa(4) (e.g. for EBus-only machines). This ISA-specific part
  isn't separated into its own source file, yet, as it requires more work
  than was feasible for 6.0 in order to do it in a clean way. Actually
  philip@ is working on a rewrite of psm(4) so a more comprehensive
  clean-up and separation of hardware dependent and independent parts is
  expected to happen after 6.0.

are affected by this problem.

Due to popularity of those models this patch is good MFC5.4 candidate.

823261a3e1 While USB keyboards attach as ukbd[0-9]+, the device node created by
kbd_attach() is called kbd[0-9]+, with a different unit number.  This
makes it impossible to write a devd rule which will automatically
switch to a USB keyboard when one is attached, because there is no way
to guess the correct device node to pass to kbdcontrol.

Therefore, change kbd_attach() to create a device node using the
keyboard device's real name (atkbd0, ukbd0...), and create the
kbd[0-9]+ node as an alias for backward compatibility.

- Change the apm driver to match the acpi driver's behavior by checking to

Note that a few places (ips(4), Alpha SMP) used "disable" instead of

fca9a10bc1 Add a a sysctl, hw.kbd.keymap_restrict_change, which acts a bit
like secure level but which restricts changes to the keymap. Its
values impose the following restrictions:

0: No restriction - this is the default.
1: Only root can change restricted keys (like boot, panic, ...)
2: Only root can change restricted keys and regular keys.
   Other users still can change accents and function keys.
3: Only root can change restricted keys, regular keys and accents.
4: Only root can change any of the keymap (restricted keys, regular
      keys, accents and function keys).

Unfortunately, the keyboard's accent map is cleared when a new keymap
is loaded, which makes the distinction between level 3 and level 4
less useful.

The MAC guys might like to make this a policy?
