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

2023-02-14T13:03:28+00:00

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

2023-02-06T22:48:47+00:00

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.

sysbeep: Adjust interface to take a duration as a sbt

2021-11-03T22:03:51+00:00

Change the 'period' argument to 'duration' and change its type to
sbintime_t so we can more easily express different durations.

Mark more nodes as CTLFLAG_MPSAFE or CTLFLAG_NEEDGIANT (17 of many)

2020-02-26T14:26:36+00:00

r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are
still not MPSAFE (or already are but aren’t properly marked).
Use it in preparation for a general review of all nodes.

This is non-functional change that adds annotations to SYSCTL_NODE and
SYSCTL_PROC nodes using one of the soon-to-be-required flags.

Mark all obvious cases as MPSAFE.  All entries that haven't been marked
as MPSAFE before are by default marked as NEEDGIANT

syscons: drop keyboard index from softc

2019-12-23T21:32:07+00:00

Analysis seems to reveal that sc->keyboard >= 0 implies sc->kbd != NULL and
there's no such scenario where sc->kbd is set (and theoretically used to
rebuild sc->keyboard) with the keyboard unavailable.

Drop the index softc. The index is only explicitly needed in few places, in
which case we can just as easily grab it from sc->kbd. There's no need for
keeping sc->kbd and sc->keyboard in sync when it can be readily accomplished
with just the former.
