atkbd: correct bogus character in #ifdef

Fixes: f20058955c9d ("sys/kbio.h: make pre-unicode keymap...")
Sponsored by: The FreeBSD Foundation

sys/kbio.h: make pre-unicode keymap support optional

FreeBSD-9 had introduced support for the full set of Unicode
characters to the parsing and processing of keymap character tables.

This support has been extended to cover the table for accented
characters that are reached via dead key combinations in FreeBSD-13.2.

New ioctls have been introduced to support both the pre-Unicode and
the Unicode formats and keyboard drivers have been extended to support
those ioctls.

This commit makes the ABI compatibility functions in the kernel
optional and dependent on COMPAT_FREEBSD13 in -CURRENT.

The kbdcontrol command in -CURRENT and 13-STABLE (before 13.2) has
been made ABI compatible with old kernels to allow a new world to be
run on an old kernel (that does not have full Unicode support for
keymaps).

This commit is not to merged back to 12-STABLE or 13-STABLE. It is
part of review D38465, which has been split into 3 separate commits
due to different MFC and life-time requirements of either commit.

Support Unicode characters in keymap dead key tables

Support for Unicode characters had been added to the keyboard code,
but there are keymaps that have accented characters accessed via dead
key combinations, and those were still restricted to 8 bit codes.

This update to kbd.c adds support for Unicode characters and
compatibility code that allows a kbdcontrol command built from kbio.h
without these patches to work on a new kernel.

Compatibility code that allows a new kbdcontrol binary running on an
old kernel to load and display the dead key map will be committed in a
separate commit.

Add comments about the validation.

Validate INT 15h and 16h vectors more strictly. Traditionally these entry
points are fixed addresses and (U)EFI CSM specification also mandated that.
Unfortunately, (U)EFI CSM specification does not specifically mention this
is to call service routine via interrupt vector table or to jump directly
to the entry point. As a result, some CSM seems to install two routines
and acts differently, depending on how it was executed, unfortunately.
When INT 15h is used, it calls a function pointer (which is probably a UEFI
service function). When it jumps directly to the entry point, it executes
a simple and traditional INT 15h service routine. Therefore, actually there
are two possible fixes, i. e., this fix or jumping directly to the fixed
entry point. However, we chose this fix because a) keyboard typematic
support via BIOS is becoming extremely rarer and b) we cannot support random
service routine installed by a firmware or a boot loader. This should fix

by /etc/rc.d/jail.

framebuffer driver, etc. work on FreeBSD/amd64.

A significant amount of improvements were done by jkim@ during the recent

work is based on OpenBSD's x86emu implementation and contributed by
paradox <ddkprog yahoo com> and swell.k at gmail com.

Hopefully I have stolen all their work to 8-STABLE :)

All bugs in this commit are mine, as usual.

Rewrite x86bios and update its dependent drivers.

- Do not map entire real mode memory (1MB). Instead, we map IVT/BDA and
ROM area separately. Most notably, ROM area is mapped as device memory
(uncacheable) as it should be. User memory is dynamically allocated and
free'ed with contigmalloc(9) and contigfree(9). Remove now redundant and
potentially dangerous x86bios_alloc.c. If this emulator ever grows to
support non-PC hardware, we may implement it with rman(9) later.
- Move all host-specific initializations from x86emu_util.c to x86bios.c and
remove now unnecessary x86emu_util.c. Currently, non-PC hardware is not
supported. We may use bus_space(9) later when the KPI is fixed.
- Replace all bzero() calls for emulated registers with more obviously named
x86bios_init_regs(). This function also initializes DS and SS properly.
- Add x86bios_get_intr(). This function checks if the interrupt vector is
available for the platform. It is not necessary for PC-compatible hardware
but it may be needed later. ;-)
- Do not try turning off monitor if DPMS does not support the state.
- Allocate stable memory for VESA OEM strings instead of just holding
pointers to them. They may or may not be accessible always. Fix a memory
leak of video mode table while I am here.
- Add (experimental) BIOS POST call for vesa(4). This function calls VGA
BIOS POST code from the current VGA option ROM. Some video controllers
cannot save and restore the state properly even if it is claimed to be
supported. Usually the symptom is blank display after resuming from suspend
state. If the video mode does not match the previous mode after restoring,
we try BIOS POST and force the known good initial state. Some magic was
taken from NetBSD (and it was taken from vbetool, I believe.)
- Add a loader tunable for vgapci(4) to give a hint to dpms(4) and vesa(4)
to identify who owns the VESA BIOS. This is very useful for multi-display
adapter setup. By default, the POST video controller is automatically
probed and the tunable "hw.pci.default_vgapci_unit" is set to corresponding
vgapci unit number. You may override it from loader but it is very unlikely
to be necessary. Unfortunately only AGP/PCI/PCI-E controllers can be
matched because ISA controller does not have necessary device IDs.
- Fix a long standing bug in state save/restore function. The state buffer
pointer should be ES:BX, not ES:DI according to VBE 3.0. If it ever worked,
that's because BX was always zero. :-)
- Clean up register initializations more clearer per VBE 3.0.
- Fix a lot of style issues with vesa(4).

Fix couple of style nits missed in the previous commit.

- Use x86bios_offset() instead of BIOS_PADDRTOVADDR() macro.[1]
- Clear all registers before calling real mode interrupt handlers as we did
for dpms and vesa and re-enable the function as it should be fixed by this.
- Tidy up register access. For example, when we call INT 0x15, AH=0xc0,
we used to initialize AX=0xc000 to clear AL at the same time but it is
very confusing. We don't have to do this any more because we are explicitly
clearing all registers now.
- Check size of system configuration table although it is almost always 8.
This is to make sure we are not reading some random low physical memory.
Hopefully it is just zero in that case. :-)
- Fix some style nits and add more comments.

Fix LEDs not working when atkbd is an active keyboard and the physical
keyboard is attached only after the system has already booted.

If USB keyboard is also present, and there's no kbdmux(4), the problem
has been hiding itself because as soon as we get to multi-user, the
USB keyboard becomes an active keyboard (see devd.conf), thus marking
atkbd inactive and letting the old code initialize the keyboard.

With kbdmux(4), or if there's no USB keyboard, the atkbd keyboard is
always active, whether it's physically attached or not, thus it never
initialized itself properly on a physical attach.

To fix this, move block that initialized the keyboard on attach upper
so it doesn't depend on the (KBD_IS_ACTIVE(kbd) && KBD_IS_BUSY(kbd))
condition. Also move KBD_FOUND_DEVICE() a few lines upper so that
KDSETLED and KDSETREPEAT that follow it propagate to the controller.

Send the pcvt(4) driver off to retirement.

Remove various bits of conditional Alpha code and fixup a few comments.

Use the same method for detecting actual presence of AT-style keyboard
controller as we use in boot blocks (querying status register until
bit 1 goes off). If that doesn't happed during reasonable period assume
that the hardware doesn't have AT-style keyboard controller. This makes
FreeBSD working almost OOB on MacBook Pro (still there are issues with
putting second CPU core on-line, but since installation CD comes with
UP kernel with this change one should be able to install FreeBSD without
playing tricks with hints). Other legacy-free hardware (e.g. IBM NetVista
S40) should benefit from this as well, but since I don't have any I can't
verify.

It should make no difference on the ordinary i386 hardware (since in
that case that hardware already would be having an issues with A20
routines in boot blocks). I don't know much about AT-style keyboard
controller on other platforms (and don't have dedicated access to one),
therefore, the code is restricted to i386 for now. I suspect that amd64
may need this as well, but I would rather leave this decision to someone
who knows better about the platform(s) in question.

I have tested this change on as many "ordinary i386 boxes" as I can get
my hands on, and it doesn't create any false negatives on hardware with

- 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

The bulk of the work was done over the last few years by Doug Rabson and
Garrett Wollman.

Keyboard driver update in preparation for the USB keyboard driver.

- Refined internal interface in keyboard drivers so that:
1. the side effect of device probe is kept minimal,
2. polling mode function is added,
3. and new ioctl and configuration options are added (see below).

- Added new ioctl: KDSETREPEAT
Set keyboard typematic rate. There has existed an ioctl command,
KDSETRAD, for the same purpose. However, KDSETRAD is dependent on
the AT keyboard. KDSETREPEAT provides more generic interface.
KDSETRAD will still be supported in the atkbd driver.

- Added new configuration options:
ATKBD_DFLT_KEYMAP
Specify a keymap to be used as the default, built-in keymap.
(There has been undocumented options, DKKEYMAP, UKKEYMAP, GRKEYMAP,
SWKEYMAP, RUKEYMAP, ESKEYMAP, and ISKEYMAP to set the default keymap.
These options are now gone for good. The new option is more general.)

KBD_DISABLE_KEYMAP_LOADING
Don't allow the user to change the keymap.

- Fixed the bug which always ignored Ctrl-Pause/Break on the AT 101
keyboard.
- Translate some keycode for the 84 keyboard so that the 84 keyboard
and the 101 keyboard become more compatible in terms of keycodes.
- Updated the built-in keymaps so that it is in line with the recent
changes in share/syscons/keymaps.
- Added some comment on the Pause/Break key on the 101 keyboard.

syscons
- Bring down the splash screen when a vty is opened for the first
time.
- Make sure the splash screen/screen saver is stopped before
switching vtys.
- Read and save initial values in the BIOS data area early.
VESA BIOS may change BIOS data values when switching modes.
- Fix missing '&' operator.
- Move ISA specific part of driver initialization to syscons_isa.c.

atkbd
- kbdtables.h is now in /sys/dev/kbd.

all
- Adjust for forthcoming alpha port. Submitted by: dfr

Use the correct macro to test flags; we need KBD_IS_INITIALIZED here,
not KBD_IS_PROBED.

Add the new keyboard driver and video card driver. They will be
used by console drivers.

(They are not yet activated yet. Wait for announcement later.)
