* sys/kbio.h: make pre-unicode keymap support optionalStefan Eßer2023-02-141-5/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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 tablesStefan Eßer2023-02-061-4/+48
| | | | | | | | | | | | | | | | | | | 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.

* kbd: replace vestigial spl calls with Giant assertionsEd Maste2022-03-241-55/+12
| | | | | | | | | | | | | | | | | | | | | The keyboard driver was initially protected via spl* interrupt priority calls but (as part of a comprehensive effort) migrated to use the Giant lock (mutex). The spl calls left behind became NOPs but they can be confusing as they have no bearing on the actual mutual exclusion that is now present. Remove them from kbd and add assertions that Giant is held. markj notes that there is conflation between the "bus topo" lock (which is Giant under the hood) and Giant. The assertions could either be addressed as a small item along with bus topology locking work or they'll be removed if kbd is decoupled from Giant.

| | | | | | | | | | | | | | | | During boot we warn that the kbd and openfirm drivers are Giant-locked and may be deleted. Generally, the warning helps signal that certain old drivers are not being maintained and are subject to removal, but this doesn't really apply to certain drivers which are harder to detangle from Giant. Add a flag, D_GIANTOK, that devices can specify to suppress the misleading warning. Use it in the kbd and openfirm drivers.

* kbd: merge linker set drivers into standard kbd driver listKyle Evans2019-12-261-44/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This leads to the revert of r355806; this reduces duplication in keyboard registration and driver switch lookup and leaves us with one authoritative source for currently registered drivers. The reduced duplication later is nice as we have more procedure involved in keyboard setup. keyboard_driver->flags is used to more quickly detect bogus adds/removes. From KPI consumers' perspective, nothing changes- kbd_add_driver of an already-registered driver will succeed, and a single kbd_delete_driver will later remove it as expected. In contrast to historical behavior, kbd_delete_driver on a driver registered via linker set will now actually de-register the driver so that it may not be used -- e.g. if kbdmux's MOD_LOAD handler fails somewhere. Detection for already-registered drivers in kbd_add_driver has improved, as the previous SLIST_NEXT(driver) != NULL check would not have caught a driver that's at the tail end. kbdinit is now called from cninit() rather than via SYSINIT so that keyboard drivers are available as early as console drivers. This is particularly important as cnprobe will, in both syscons and vt, attempt to do any early configuration of keyboard drivers built-in (see: kbd_configure).

| | | | | | | | | | This is needed after r355796. Some double-registration of kbd drivers needs to be sorted out, then this sysinit will simply add these drivers into the normal list and kill off any other bits in the driver that are aware of the linker set, for simplicity.

* kbd: remove kbdsw, store pointer to driver in each keyboard_tKyle Evans2019-12-161-18/+3
| | | | | | | | | | | | | | | | | | The previous implementation relied on a kbdsw array that mirrored the global keyboards array. This is fine, but also requires extra locking consideration when accessing to ensure that it's not being resized as new keyboards are added. The extra pointer costs little in a struct that there are relatively few of on any given system, and simplifies locking requirements ever-so-slightly as we only need to consider the locking requirements of whichever method is being invoked. __FreeBSD_version is bumped as any kbd modules will need rebuilt following this change.

This dependency happens as evdev_ev_kbd_event() helper references kbdsw global variable defined in kbd.c through use of kbdd_ioctl() macro.

| | | | | | | | | | | | | | | | | | Uses of mallocarray(9). The use of mallocarray(9) has rocketed the required swap to build FreeBSD. This is likely caused by the allocation size attributes which put extra pressure on the compiler. Given that most of these checks are superfluous we have to choose better where to use mallocarray(9). We still have more uses of mallocarray(9) but hopefully this is enough to bring swap usage to a reasonable level. Reported by: wosch PR: 225197 Notes: svn path=/head/; revision=328218

| | | | | | | | | | | | | | Focus on code where we are doing multiplications within malloc(9). None of these is likely to overflow, however the change is still useful as some static checkers can benefit from the allocation attributes we use for mallocarray. This initial sweep only covers malloc(9) calls with M_NOWAIT. No good reason but I started doing the changes before r327796 and at that time it was convenient to make sure the sorrounding code could handle NULL values. Notes: svn path=/head/; revision=327949

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.

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.
