Initial support for libinput Libinput is an optional dependency for getting low level input events. As opening the input devices requires root privs this is rather pointless in the current state. But there is a small added test app which can be executed with root privs to demonstrate the functionality. To properly get input events we need a wrapper like it's used in weston. So far the following is setup: * opening devices found by udev * forwarding keyboard events to InputRedirection * forwarding pointer button events to InputRedirection * forwarding pointer axis events to InputRedirection * signals emitted for pointer motion events Pointer motion events need some further work as they are provided as delta events. We need to track that and map them properly. Also missing are touch events due to me not having a touch screen. It should be fairly simple to setup the touch events, though. Also hotplugging of devices is not yet implemented.

Support LEDs in Xkb and libinput Summary: The Xkb implementation starts to track the state of the LEDs in the keymap and emits a signal whenever the LEDs change. This signal is connected to a method in LibInput::Connection which updates the led state on all devices and uses it to init the state of the led when a new device gets connected. BUG: 369214 FIXED-IN: 5.8.2 Test Plan: Connected a keyboard with LEDs and enabled NumLock and ScrollLock.

Ensure libinput connection thread uses real time scheduling Summary: The SCHED_RESET_ON_FORK results in threads (not only processes) to have the scheduling policy reset to default. This means that the libinput thread is not real time, but this was actually intended. To solve this problem KWin does start without the RESET_ON_FORK flag during startup. Once createInput has been called the scheduling is adjusted again and RESET_ON_FORK is added again. This results in the libinput thread and all threads Qt starts in between (e.g. dbus) to gain real time policy. But it is still not leaked to other processes or to threads in KWin which don't need it. Other options considered: just don't use RESET_ON_FORK and instead manually reset on fork. This would mean all threads in KWin gain real time, but we don't need this. It's only interesting for the main (rendering, Wayland thread) and the input thread. Also the danger to leak into another process is too high. Keeping the capability till the libinput thread is created and adjust the thread itself. This option was discarded as I don't want KWin to have any capabilities when the QApplication is started.

Make it possible to autodetect the tablet mode Summary: At the moment it's broken for many of the laptops I've seen, this opens the possibility to start toying with them. The right fix would be to get the kernel to emit the right signals but I'm afraid for some hardware it will be close to impossible. This includes a kconfig variable variable that will detect it as follows: if there's a touchscreen, when the touchpad gets removed we are on tablet mode (i.e. the pointing will be done using the finger), when it's connected back tablet mode will be restored.

Run clang-tidy with modernize-use-override check Summary: Currently code base of kwin can be viewed as two pieces. One is very ancient, and the other one is more modern, which uses new C++ features. The main problem with the ancient code is that it was written before C++11 era. So, no override or final keywords, lambdas, etc. Quite recently, KDE compiler settings were changed to show a warning if a virtual method has missing override keyword. As you might have already guessed, this fired back at us because of that ancient code. We had about 500 new compiler warnings. A "solution" was proposed to that problem - disable -Wno-suggest-override and the other similar warning for clang. It's hard to call a solution because those warnings are disabled not only for the old code, but also for new. This is not what we want! The main argument for not actually fixing the problem was that git history will be screwed as well because of human factor. While good git history is a very important thing, we should not go crazy about it and block every change that somehow alters git history. git blame allows to specify starting revision for a reason. The other argument (human factor) can be easily solved by using tools such as clang-tidy. clang-tidy is a clang-based linter for C++. It can be used for various things, e.g. fixing coding style(e.g. add missing braces to if statements, readability-braces-around-statements check), or in our case add missing override keywords. Test Plan: Compiles.

[libinput] Find screen for touch screen devices and calibrate accordingly Summary: This change finds the screen for a touch screen device based on: * number available screens * output name defined on the touch screen device * internal screen * and physical size The id of the screen is stored in the Device allowing to adjust the touch points accordingly. This means instead of transferring to the combined display size the touch points are transferred into the output space and the position of the output is added. Thus in a multi screen system the touch points are properly mapped to the output. Furthermore the screen orientation is passed to the Device and a calibration matrix is set accordingly. Thus a transformed screen has the touch screen transformed accordingly. Please note that this only affects libinput on Wayland and not on X11! The x11 standalone platform needs to gain similar code.

[libinput] Bind libinput support to VirtualTerminal This change is motivated by the fact that we need to suspend libinput before switching the virtual terminal. Also we don't want to take over libinput if we do not have a VirtualTerminal created - in windowed mode we don't want libinput to be started. So binding it to the backends which create the VirtualTerminal makes sense. The KWin::Application gains a new signal virtualTerminalCreated which is emitted from VirtualTerminal once it's properly setup. This is used by Input to create Libinput integration instead of binding it to logind. Furthermore Libinput gets suspended when the VirtualTerminal reports that it is no longer active. For re-activation we still just use logind's session active property.

This results in the libinput thread and all threads Qt starts in between (e.g. dbus) to gain real time policy. But it is still not leaked to other processes or to threads in KWin which don't need it. Other options considered: just don't use RESET_ON_FORK and instead manually reset on fork. This would mean all threads in KWin gain real time, but we don't need this. It's only interesting for the main (rendering, Wayland thread) and the input thread. Also the danger to leak into another process is too high. Keeping the capability till the libinput thread is created and adjust the thread itself. This option was discarded as I don't want KWin to have any capabilities when the QApplication is started.

Initial support for libinput Libinput is an optional dependency for getting low level input events. As opening the input devices requires root privs this is rather pointless in the current state. But there is a small added test app which can be executed with root privs to demonstrate the functionality. To properly get input events we need a wrapper like it's used in weston. So far the following is setup: * opening devices found by udev * forwarding keyboard events to InputRedirection * forwarding pointer button events to InputRedirection * forwarding pointer axis events to InputRedirection * signals emitted for pointer motion events Pointer motion events need some further work as they are provided as delta events. We need to track that and map them properly. Also missing are touch events due to me not having a touch screen. It should be fairly simple to setup the touch events, though. Also hotplugging of devices is not yet implemented.

Q_SIGNALS:
Pass LibInput::Device* through the event handlers Summary: The signals emitted by LibInput::Connection carry the Device for which the input event was received. This Device is passed to the input handlers. Custom event classes are added which extend QMouseEvent, QKeyEvent and QWheelEvent respectively and expose the Device. The Device is only passed around as a forward declared pointer, so even if compiled without libinput support, it should still compile. Event handlers which need to get access to the Device can now just cast the event pointer to the custom class and access it. This can be used in future to handle device specific key codes, etc. As we don't have a proper event classes for touch events the event handlers do not yet have access to the Device. Here the internal API needs to be adjusted in future. Reviewers: #plasma Subscribers: plasma-devel Tags: #plasma Differential Revision: https://phabricator.kde.org/D1667

Support for relative pointer motion events Summary: If KWin interacts with Libinput the RelativePointerManager interface gets created on the Wayland server. The ForwardInputEventFilter does forward the relative motion events in addition to the normal motion events. In order to properly support the relative motion events as they are expected by the Wayland protocol the handling of pointer motion events got slightly adjusted: * Libinput Pointer event extended by the additional data points * Libinput Pointer event carries the delta as a QSizeF instead of QPointF * PointerInputRedirection adjusted to take a pointer motion event with more arguments * Custom QMouseEvent subclass adjusted to carry the additional members The DebugConsole is adjusted to show the relative motion events in addition to the global position. Test Plan: Verified the manager object is created and verified the events in DebugConsole. Unfortunately not aware of any test application.

In future the following should be implemented: * activating e.g. zoom and present windows on pinch/swipe gesture * forwarding non global gestures to KWayland Note that forwarding to KWayland is not yet useful as QtWayland does not yet have support for the unstable protocol.

[libinput] Add support for switch devices and events Summary: This change adds support for the switch devices introduces with libinput 1.7 (lid) and 1.9 (tablet mode). So far it's not yet used internally in KWin, but only exposed through the Device and Events. As KWin currently only requires libinput 1.5 and we are rather late in the release cycle the new functionality is ifdef'ed. The requirement will be raised once master is 5.13. It is already available on build.kde.org, but e.g. Neon only has 1.6. The switch events are interesting as they report whether the lid is closed (might be interesting for e.g. powerdevil) and whether a convertible is in tablet mode (supported for e.g. Lenovo Yogas with recent kernel). This can be used by KWin internally to enable/disable the virtual keyboard. And can be exposed globally to switch to Plasma Mobile shell in future. Test Plan: Only through test case as my Lenovo Yoga uses Neon which has a too old libinput Reviewers: #kwin, #plasma Subscribers: plasma-devel, kwin Tags: #plasma Differential Revision: https://phabricator.kde.org/D9516

[libinput] Find screen for touch screen devices and calibrate accordingly Summary: This change finds the screen for a touch screen device based on: * number available screens * output name defined on the touch screen device * internal screen * and physical size The id of the screen is stored in the Device allowing to adjust the touch points accordingly. This means instead of transferring to the combined display size the touch points are transferred into the output space and the position of the output is added. Thus in a multi screen system the touch points are properly mapped to the output. Furthermore the screen orientation is passed to the Device and a calibration matrix is set accordingly. Thus a transformed screen has the touch screen transformed accordingly. Please note that this only affects libinput on Wayland and not on X11! The x11 standalone platform needs to gain similar code.

KWIN_SINGLETON(Connection)
Ensure libinput connection thread uses real time scheduling Summary: The SCHED_RESET_ON_FORK results in threads (not only processes) to have the scheduling policy reset to default. This means that the libinput thread is not real time, but this was actually intended. To solve this problem KWin does start without the RESET_ON_FORK flag during startup. Once createInput has been called the scheduling is adjusted again and RESET_ON_FORK is added again. This results in the libinput thread and all threads Qt starts in between (e.g. dbus) to gain real time policy. But it is still not leaked to other processes or to threads in KWin which don't need it. Other options considered: just don't use RESET_ON_FORK and instead manually reset on fork. This would mean all threads in KWin gain real time, but we don't need this. It's only interesting for the main (rendering, Wayland thread) and the input thread. Also the danger to leak into another process is too high. Keeping the capability till the libinput thread is created and adjust the thread itself. This option was discarded as I don't want KWin to have any capabilities when the QApplication is started.
