The key element of the improvement is differentiated processing of
events of the following device types.
Mouse: relative motion
Pointer: absolute motion (Qemu usb-tablet and IP-KVM devices)
Touchpad: relative motion via absolute touchpad coordinates
Touchtool: absolute motion (e.g., stylus)
Touchscreen: absolute motion and finger (multi-) touch
Processing is done in two stages for one "input packet". First, all
events of the packet are recorded into the current evdev state with
device-type specific operations. Then, appropriate Genode input events
are generated from the accumulated evdev state in the submission stage
(again by device-type specific functions).
A simple version of tap-to-click was added to the touchpad support.
Fixes#5105
The former implementation relied on input drvdata always pointing to
struct hid_device, which is not true for Wacom touch devices (at least).
Now, we implement the input handler for devices providing LEDs
(evbit[EV_LED] set) only and use input_inject_event() to set the LED
states.
* Switch from the legacy usb_host driver to the new PC version
in recipes and automated tests
* Update documentation snippets
* Remove outdated, unused usb_rndis run-script
Fixgenodelabs/genode#4416
* The device XML information dataspace is only provided,
when the client's policy states `info="yes"`
* The device XM information gets changed to include the
physical resource names (I/O memory and IRQ addresses)
instead of virtual ids and page offset
Fix#4077
* Remove SPEC declarations from mk/spec
* Remove all board-specific REQUIRE declaratiions left
* Replace [have_spec <board>] run-script declarations with have_board where necessary
* Remove addition of BOARD variable to SPECS in toplevel Makefile
* Move board-specific directories in base-hw out of specs
