* chore: replace {0, 0} with {DEV,KOBJ}METHOD_ENDEnji Cooper10 days3-4/+4
| | | | | | | | | | | | | | Both of the aforementioned macros have been present in FreeBSD for well over a decade: 2009 for `KOBJMETHOD_END`; 2011 for `DEVMETHOD_END`. Adapt all hardcoded references of `{0, 0}` with `DEVMETHOD_END` and `KOBJMETHOD_END` as appropriate. This helps ensure that future adaptations to drivers following patterns documented in driver(9) can be made more easily/without issue.

* bus: Document special ranges of IVARsJohn Baldwin2026-02-171-1/+1
| | | | | | | | | | | | | Some IVAR indices are special in that they have global meaning across multiple buses where as other IVARs are always private to the local bus. Try to document this a bit and add constants for the various ranges to avoid future conflicts. This is a no-op, but IVAR indices are now generally defined as enums as that makes it easier to define them in terms of ranges.

* atkbdc: Add additional heurstic for Chromebook keyboardsWarner Losh2023-09-091-0/+11
| | | | | | | | | | | | | | | It turns out that that heurstic used to determine if we have a Google coreboot, and thus have the i8042 emulation bugs, is incorrect. At least one Acer "Peppy" Chromebook has an issue because Acer space'd out the smbios.bios.version string we're using as part of the heuristic. So, if the version starts with a space, then enable the workarounds if the smbios.bios.reldate is 2018 or earlier. While not perfect, it should be a reasonable dividing line and still allow newer core boot-based machines that aren't Chromebooks to not have the workaround.

* atkbc: Better test for old chromebooksWarner Losh2023-06-291-11/+29
| | | | | | | | | | | | | | | | | | | | Older Chromebooks have issues in their embedded controller (EC) firmware which need working around in atkbd and atkbdc. On these systems, rather than use a standard EC, Google used their own arm-based EC. For a while, its firmware incorrectly implemented the i8042, requiring workaroundsd in the driver. Implement a heuristic recommended by MrChromebox <mrchromebox@gmail.com> to detect them: If the bios.version starts with Google_, or the maker is either Google or GOOGLE, assume that it's a chromebook with the affected bios. While this isn't strictly true, the number of updated systems without the bug is very small and this will exclude all the non-Google coreboot user that use a standard EC. There's no simple way to test the hardware to see if it's implemented with the buggy EC.

* sys/kbio.h: make pre-unicode keymap support optionalStefan Eßer2023-02-141-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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 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.

| | | | | | | | | | | | | | | | r123442 introduced solution for clamping of PS/2 mice jitter when using a KVM. Solution is to buffer mouse packets for 0.050ms if mouse activity has not been seen for more than 0.5 seconds. Then flush that data to driver if no validation errors found or drop the entire queue otherwise. While it works well with relative devices it has issues with absolute ones Depending on history buffering may results in delaying of the touch front edge for 0.050ms that affects gesture processing (tap detection). As absolute touchpads usually are built-in devices we can safely disable bufferization and KVM jitter clamping to avoid such a delays. MFC after: 2 weeks
