evdev: Extend EVIOCGRAB ioctl scope to cover kbd interface

2022-11-18T23:54:46+00:00

of various keyboard drivers.
EVIOCGRAB ioctl execution on /dev/input/event# device node gains
exclusive access to this device to caller. It is used mostly for
development purposes and remote control software. See e.g.
https://reviews.freebsd.org/D30020 which is the reason of creation
of this change.
Keyboard grabbing is disabled in KDB and during panics.

evdev: Add implicit mode for touch tracking.

2021-08-24T22:52:37+00:00

In implicit mode assignment of slot number and tracking id is performed
automatically on each synchronization requested by device driver.

This is done with creation of intermediate buffer for multitouch events.
This buffer holds untracked events until synchronization is requested by
device driver. It is needed as touch assigment requires
knowledges of all touch positions pushed in current and previous reports.

evdev: Make MT tracking IDs monotonically increasing sequence.

evdev: force no fuzz for autogenerated single touch compat events.

2021-08-24T22:45:50+00:00

As fuzz has already been applied on multitouch event processing.
This allows to remove existing workaround for double fuzz procesing.

evdev: Multitouch code style changes.

2021-08-24T22:43:41+00:00

1. Move touch count reporting helpers to utils. They are not multitouch.
2. Use evdev_mt prefix for private multitouch support routines.
3. Use int instead of int32_t where fixed size is not required.
4. Export some internal functions.

This change should be no-op.

evdev: Use bit_foreach helper macro

2021-08-16T21:29:47+00:00

for traversing all bits set in the bitstring(9).

While here move bit_change() definition to common header.

evdev: Do not check maximal contact number for MT initialization

2021-08-16T20:12:01+00:00

This allows singletouch devices which use multitouch protocols to work.
