The logic on page flips was inconsistent in the sense, that it should never
release a GBM buffer before it's not used (i.e. viewable on the display)
anymore. This happened unintended until now (on page flip we never really
did something useful in the else statement, because if we're here it's not
a GBM buffer anyway).
With this patch we:
* delete on page flips always only the old buffer, which is not used anymore
* release the buffer earlier on interrupts like display disconnect in order
to be able to destroy the EGL context
Test Plan:
Tested in non atomic mode (atomic mode is obsolete right now until my other
WIP patch D4539 is ready to be merged): Login, logout, suspend, normal use.

Summary:
The functionality regarding triggering modifier only shortcuts is moved
out of Xkb - where it doesn't belong to - and is turned into an input
event spy listening for the changes it is interested in. Previously
the state got queried by asking e.g. for the pressed buttons, now it's
tracked directly.
The X11 side needs a larger change due to that as now pushing the events
into Xkb does not trigger modifier only shortcuts any more. Instead the
"normal" way through the platform API needs to be used which triggers the
processing of filters and spies.
The problem here is that our redirections only process events if they are
inited and that only happens on Wayland. We cannot call init on them as
that would create all the Wayland filters and spies and processing would
probably break. As an intermediate solution the spies are now processed
and there we know that it won't matter. A future solution would be to
remove the init checks completely and just send through both filters and
spies and ensure that on X11 only the supported ones are loaded.

Summary:
Instead of having the egl extensions in the global kwinglutils lib it
becomes private to the AbstractEglBackend. Just like on glx the
glxextensions are moved into the platform.
The extensions are queried from initEglAPI, that is as early as possible
after initializing the EGLDisplay. This ensures that any implementing
subclass can access the extensions early enough.
As a note: the EglOnXBackend had a potentially wrong sequence for
initializing the buffer age extension. It is now moved to the correct
place where the result is needed for the first time.
From the global API eglExtensions are removed from hasGLExtension and
the eglExtensions function is dropped. As by that initEGL did not do
anything it is also dropped.

Summary:
A new virtual method is added to Platform:
startInteractiveWindowSelection
The interactive window selection enters a mode where the user can select
a window through the pointer or keyboard device. The cursor is turned
into a crosshair cursor, unless another cursor name is provided (e.g.
pirate for kill window).
Once a window is selected the provided callback method is invoked with
the selected Toplevel as argument. In case the user cancelled the
selection a nullptr argument is passed in.
Currently it's only implemented by the X11 standalone platform using the
logic from KillWindow. Just instead of killing the window the callback
is invoked.
KillWindow loses the X11 implementation and interacts with the new
functionality in Platform by providing a lambda function for the
killing.

Summary:
KWin still resolves some OpenGL function pointers. For that it needs to
use either eglGetProcAddress or glxGetProcAddress. With other words the
method to resolve needs to know whether it is egl or glx and needs both
a dependency to egl and glx. Especially the dependency to glx is ugly as
that pulls in XLib into our library.
The way so far was to pass an enum value to the initGL method to know
whether it's EGL or GLX. With this change the enum value is removed and
replaced by a function pointer to resolve the methods.
This simplifies the resolve code and allows to completely remove the glx
variant we still had in the library. Thus kwinglutils library is now glx
and XLib free.

This change introduces a new method in the Platform to hide and show the

takes care of only showing again if all hide got matched by a show.
The actual hiding and showing is performed in the platform plugins. So

On build.kde.org the autotests started to crash on tear down due to a
newer Wayland library. The reason is that the KWayland::Client::Outputs
are destroyed after the internal Wayland connection is destroyed.
This change parents the created Outputs to the Registry like the other
objects. To ensure that the KWin::QPA::Screen doesn't have a problem
with that, it is changed to a QPointer - nullptr checks are already in
place.
Hopefully that will fix the crashes on build.kde.org, but there is a
chance that more errors are hidden.
Summary:
With nouveau driver it can happen that KWin gets frozen when first trying
to render with OpenGL. This results in a freeze of the complete desktop
as the compositor is non functional.
Our OpenGL breakage detection is only able to detect crashes, but not
freezes. This change improves it by also added a freeze protection.
In the PreInit stage a thread is started with a QTimer of 15 sec. If the
timer fires, qFatal is triggered to terminate KWin. This can only happen
if the creation of the OpenGL compositor takes longer than said 15 sec.
In the PostInit stage the timer gets deleted and the thread stopeed
again.
Thus if a freeze is detected the OpenGL unsafe protection is written into
the config. KWin aborts and gets restarted by DrKonqui. The new KWin
instance will no longer try to activate the freezing OpenGL as the
protection is set.
If KWin doesn't freeze the protection is removed from the config as
we are used to.
Check for freezes for the first n frames, not just the first
This patch changes the freeze detection code to detect freezes in the
first 30 frames (by default, users can change that with the
KWIN_MAX_FRAMES_TESTED environment variable). This detects
successfully the freezes associated to nouveau drivers

unconditionally to get the cursor which obviously does not work on
Wayland.
This change adds a new class PlatformCursorImage to kwinglobals which
wraps what a cursor is (image and hotspot) and adds a new virtual method
to Platform to provide such a PlatformCursorImage. By default it's the
cursor image the Platform tracks. On X11/standalone platform this new
virtual method is overriden and provides a PlatformCursorImage from X11
using the code previously used in screenshot effect.
Screenshot effect and zoom are adjusted to use the new API instead of
X11.

Summary:
The modifier-only-shortcuts break as soon as KWin grabs the keyboard
(e.g. alt+tab, present windows, etc.). The investigation shows that in
that case KWin does not get any raw key events any more and thus gets
confused about the state of the hold modifiers. E.g. alt+tab has the
alt key pressed, but we miss the release as the keyboard is grabbed.
This change addresses the problem by installing an additional event
filter for key press and release event which only filters for key events
on the root window. That way we can be sure that it only operates when
KWin grabbed the keyboard on the root window.
Note: the problem only exists when grabbing on the root window. If the
grab is on another window (e.g. moving a window) we still do get all
events.
The problem also seems to not happen if another application grabbed
keys on the root window. E.g. for key combinations grabbed by
kglobalaccel the correct sequence of key press/release as raw events
are reported. Also while the screen is locked the evemts are reported
and kscreenlocker grabs the keyboard on the root window.

Used Alt+Tab and Present Windows and tried to activate launcher
afterwards.

This is Milestone 1 of full support of Atomic Mode Setting (AMS) and
Universal Planes in the KWin DRM backend.
With Milestone 1 we can use the primary plane of a DRM output and do an
AMS commit (this means mode setting aswell as page flipping), if the
driver supports it. Until now the functionality is only tested on Intel
graphics. You need the drm-next kernel for most recent DRM kernel
developments. As boot option set "i915.nuclear_pageflip". Additionally
at the moment AMS is still hidden behind the environment variable
KWIN_DRM_AMS. Set it, if you want to try out AMS.

Summary:
SharingPlatformContext::swapBuffers needs to make the context current.
For this is calls makeCurrent. Later on this tries to bind a fbo, which
checks calls into the current QOpenGLContext. As we called makeCurrent on
our own platform context Qt doesn't know that the context is current and
returns in the worst case a nullptr and crashes.
This change calls makeCurrent on the QOpenGLContext so that Qt also knows
that this context is current now. The QOpenGLContext calls makeCurrent on
the platform context, so what our code tried to do is still being done.
In addition the method context() in AbstractPlatformContext is renamed to
eglContext to no longer shadow the method in QPlatformContext.

Summary:
The raw pointer button events intercepted in the XInput2 input filter
get sent through the Platform to the PointerInputRedirection. This
makes the PointerInputRedirection track the pointer button state and
emit the signals for button changed and axis changed.
These signals are used by the modifier-only shortcut detection to
determine whether the shortcut should trigger.
On X11 the "normal" input handling doesn't use the InputRedirection
and the emitted signals are not consumed by anything else. As
PointerInputRedirection is not inited the events are not forwarded
to the input filter, thus won't be processed by other parts and
won't interfere with the normal event processing on X11.
Given that it also doesn't matter that the input filter does not
apply the left-handed setting. The internal tracking will have a
wrong mouse button, but nothing is going to do decisions based on
the value of the pressed mouse button. For the moment all we are
interested in is that a button is pressed.

BUG: 367730
Just like 4e7392b907:
the ownership of the gbm_device must be passed to the Platform as
the ownership of the EGLDisplay is also passed to the Platform and
we may not destroy the gbm_device for an EGLDisplay we are still using.
With this change I could restart the OpenGL compositor successfully
and switch from OpenGL 3.1 to OpenGL 2 without a crash or rendering
issues.
The Egl backend opens the drm device and creates a gbm_device from it.
From that it creates the EGL device. The EGL device outlives the EGL
backend (e.g. for compositor restart). So far the EGL backend destroyed
the gbm_device when going down which mesa did not like at all when a
new context got created on that EGL device.
Thus the ownership of gbm_device is also passed to the Platform so that
the compositor can be restarted.
This makes the TestSceneOpenGL no longer crash during the restart
compositor test.
At the same time the xinput2 integration is split out of X11Cursor
and made a standalone part of the platform plugin. XInput integration
is nowadays not only used by the cursor position polling, but also
for modifier only shortcuts.
By splitting it out the modifier shortcuts start to work also when
one doesn't have anything requesting a mouse position polling.
This also simplifies the conditional builds: xinput integration is
only included if we have support for it at compile time without having
to have many ifdefs in the cursor implementation. For the inclusion of
cursor in the kcmkwin this also removes all the ifdefs.
The key events are only requested if we have xinput 2.1. Otherwise we
would not get all raw events if the input device gets grabbed.

Summary:
Rational: unredirect fullscreen windows is a weird beast. It's intended
to make fullscreen windows "faster" by not compositing that screen. But
that doesn't really work as KWin jumps out of that condition pretty
quickly. E.g. whenever a tooltip window is shown. KWin itself has a
better functionality by supporting to block compositing completely.
The complete code was full of hacks around it to try to ensure that
things don't break.
Overall unredirect fullscreen has always been the odd one. We had it
because a compositor needs to have it, but it never got truly integrated.
E.g. effects don't interact with it properly so that some things randomly
work, others don't. Will it trigger the screenedge, probably yes, but
will it show the highlight: properly no.
By removing the functionality we finally acknowledge that this mode is
not maintained and has not been maintained for years and that we do not
intend to support it better in future. Over the years we tried to make
it more and more hidden: it's disabled for Intel GPUs, because it used
to crash KWin. It's marked as an "expert" option, etc.
It's clearly something we tried to hide from the user that it exists.
For Wayland the whole unredirect infrastructure doesn't make sense
either. There is no such thing as "unredirecting". We might make use
of passing buffers directly to the underlying stack, but that will be
done automatically when we know it can be done, not by some magic is
this a window of specific size.

If the event processing is started before everything is fully started
it can happen that we have "evil" events which may crash either Xwayland

that it can happen that the wl_output gets destroyed while Xwayland tries
to bind to it and will crash. Thus let's delay all events till we are
ready to process them.
Summary:
The egl implementation for the virtual platform tries to use a render
node if available. If there is no render node it looks for a virtual
(kernel driver vgem) device, which unfortunately does not create a
render node in mainline kernel (there are patches in ChromiumOS).
For this the Udev wrapper is extended to search for renderNode devices
and for virtual dri devices.
If either render node or vgem dri device is found, it is tried to be
opened (without logind escalation) and on success a gbm device is
created on it. If any step of this fails the so far default behavior
of default device is tried for creating the EGLDisplay.
All of this is compile optional, so that the virtual platform does not
hard depend on udev and/or gbm.
Test Plan:
Auto tests which need OpenGL executed and verified that they
use the render node or vgem device.

of EGLDisplay for one native platform.
This change tries to also use the SharingPlatformContext if there is
an OpenGL context in general. It reuses the native EGLSurface created
for the compositing scene and makes its own OpenGL context current on
that surface, too. As KWin creates an FBO, it never renders to it, so
it shouldn't matter at all.

current also the EGLConfig from the scene is used to create the context.

Summary:
KWin needs to support restarting the OpenGL compositor in case of a
graphics reset event.
On Wayland the tricky part is that the applications should not notice
this. Most importantly KWin cannot just destroy the EGLDisplay and create
a new one. But this is how a restart works: the complete compositor gets
torn down and recreated - including the EGLDisplay.
This change moves ownership of the EGLDisplay to the Platform.
The AbstractEglBackend subclasses query the Platform whether there is
already an EGLDisplay. Only if there is no EGLDisplay the EGLDisplay is
created and only if no EGLDisplay is registered with Wayland the bind
is performed.
Another change is regarding the destruction: the AbstractEglDisplay does
no longer unbind the Wayland display and does no longer destroy the
EGLDisplay. The EGLDisplay is destroyed by the Platform - so very late
on application exit. The Wayland display is unbound when the Compositor
terminates.
Test Plan:
Limited testing with the added auto-test. This one needs to
be extended to fully verify that OpenGL applications continue to work.
But this requires build.kde.org to support OpenGL on Wayland.

and any changes were not catched.
This change makes WaylandServer listen to changes to the Screens and
sync them to Wayland.
Unfortunately KWin's internal Screen information is not sufficient to
properly synchronize this to Wayland and also Wayland by not supporting
adding/removing modes does not help.
Thus the solution implemented here is to add new outputs reflecting the
changes and then removing the old ones. This creates situations with more
outputs being present than actually there, but prevents that there are
no outputs at all.

So far if the framebuffer platform run into an error on initialization
it did not continue and caused the system to freeze. With this change
it properly emits the initFailed signal in all error conditions which
causes kwin_wayland to terminate. This is a much better situation than
just staying in a running, but frozen state.

Summary:
If it's not possible to create a buffer to blank the output, KWin won't
be able to render to the output. In that case the output should not be
added to the list of outputs.
To support this DrmOutput::blank and DrmOutput::init return bool to
indicate whether they succeeded. DrmBackend handles this situation and
doesn't add the output to the list of outputs if init failed.
If after init there are no outputs KWin is in a state where it won't
be functional. Thus the platform emits the initFailed signal to
terminate.

Summary:
To use eglCreateImageKhr for an X11 pixmap we need an EGLDisplay created
for the same XDisplay as the X11 pixmap. This means if we created an
EGLDisplay for a GBM device, we are not allowed to load a texture from
the X11 pixmap and can result in a crash in the driver.
Similar in the nested X11 setup the EGLDisplay is created for the
rendering window, but the X11 pixmaps are from the Xwayland server KWin
started. They don't belong to the same windowing system.
This change addresses this problem by moving the loading of X11 pixmaps
from AbstractEglTexture to EglTexture of the EglOnX11Backend. Thus for
any usage on a non X11 platform we cannot hit the code path any more.
In addition the nested X11 platform can indicate that it doesn't support
it and thus also doesn't go through the code path.

Summary:
The idea is to have KWin provide a virtual keyboard. To support this
KWin uses the QT_IM_MODULE qtvirtualkeyboard and makes sure that the
QPA plugin loads it.
KWin has a new class VirtualKeyboard which acts as the focus object and
the "proxy" for input methods. The QPA plugin ensures that this is the
focusObject, so that all input method related events are sent to this
class. From there it will be possible to delegate to other applications
through the Wayland interfaces.

Summary:
A new virtual method createOpenGLSafePoint is added to Platform.
This is invoked through the Compositor with a PreInit and a PostInit
argument pre and post creating the SceneOpenGL.
The Platform plugin can implement this and use it for detecting whether
creating the OpenGL compositor on this platform crashed in the past.
Thus it's the base for the openGLIsBroken platform check.
The x11 standalone plugin is the first to implement this functionality
using the previous code which was designed for X11.
This also means that a crash of the OpenGL compositor during init on
Wayland won't result in OpenGL being disabled.

This is technically no longer correct for quite some time. Just because
GLX is not available doesn't mean that OpenGL doesn't work. We have an
EGL backend. So let's try to use that if glx is not available.
This change removes the check completely from Compositor. Instead the
standalone x11 plugin checks whether glx is available prior to createing
the glx backend. If not available it falls through to the egl backend.

Wayland checks removed.
In addition all calls to CompositingPrefs now go through the platform

Removes a diversion between X11 and Wayland. The base class Platform
creates an instance of class Edge with plugin implementations being
able to create a different type.
The X11StandalonePlugin does that and creates a WindowBasedEdge. For
this the implementation of WindowBasedEdge is moved from screenedges
into the plugin.
Unfortunately an ifdef is needed to make the screenedge test still
work as expected. This should be improved in future, e.g. have a good

This makes QCursor::pos and QCursor::setPos function correctly. KWin
actually wouldn't need it as KWin has the KWin::Cursor replacement, but
it allows Qt internal API to have it function correctly and also the
zoom effect does use QCursor::setPos.
We need to also destroy all idle objects when we tear down the
internal client connection. Otherwise the cleanup tries to free
the object after our Wayland connection is already destroyed.
During startup it might happen that the QPA is already loaded, but
the wayland server and it's internal connection not yet fully
created. Thus safety check for it.
This is needed to make KWin build-able on non-Linux, but is actually
only a workaround. The dependency should also be available on non-Linux.
This disables the EGL integration in the Wayland backend (QPainter still
available) and the EGL fallback in the qpa plugin (preferred context
sharing still available, but requires a working OpenGL Scene).
REVIEW: 126202
ASAN righly complained: we need to delete our Wayland objects before
we destroy the internal client connection. Solved by better setting
parent relationships in the QPA plugin and correctly delete objects
in destroy of internal client connection.
We need to destroy the compositor after Xwayland terminated and after
the internal Wayland connection is destroyed. This means when destroying
the Workspace we may no longer destroy the Compositor at the same time.
Also we need to ensure that other tear down functionality doesn't call
into the no longer existing internal client connection.
With this change kwin doesn't crash when exiting with Wayland and/or
X11 windows still open.
Basically a simplified fork from kwayland-integration.
We cannot use the idletime plugin from kwayland-integration as it
a) doesn't react on our own qpa plugin name
b) performs blocking roundtrips in the main thread -> freeze
This simplifies by using our internal registry and we don't even check
whether Seat and Idle are announced: we know they are.

KGlobalAccel plugin gets deleted by a global static. At that point
InputRedirection is already deleted but the plugin holds a static pointer
to it.
This change connects to the deleted signal by InputRedirection and
ensures that the plugin doesn't call into the deleted code any more.
This is the beginning of a new testing era for KWin: finally we are
able to test against a running KWin. This works by making use of the
new virtual framebuffer backend for Wayland. It starts a specific
Application subclass which is mostly a fork of ApplicationWayland.
The individual tests are able to influence the socket name and the
size of the virtual screen. This is supposed to be done in
initTestCase. To know when KWin is fully started one can use the
workspaceCreated signal of KWin::Application. KWin is not started in
another process, but the kwin library is used, so the test has pretty
much full introspection to everything going on inside KWin. It can
access the Workspace, WaylandServer, fake input events through
InputRedirection and so on.
Once the test KWin is running it's possible to connect to it using
KWayland::Client library. This allows to introspect the Workspace
to see whether all worked as expected (e.g. correct stacking order,
active window and so on).
This first autotest is mostly meant to illustrate how to setup a
test and how one can use KWayland::Client to interact with the mock
KWin. For more tests it is suggested to move the connections to the
Wayland server in the init() and cleanup() methods.
The change also affects the qpa plugin: the specific check to only
run in binaries called kwin_wayland doesn't hold any more. This can
now be overwritten by an env variable.
Please note that this first test will probably fail in the CI system
as it might not have XWayland which is needed by KWin.
We no longer need to have the event dispatcher created before starting
the QApplication, thus we can leave it to the QPA plugin to creat it.
Also we don't need to implement our own dispatcher any more but can
use one from Qt5PlatformSupport as we link it anyways. The special
need for dispatching the WaylandServer is no longer needed as we can
explicitly dispatch it from the QPA plugin if needed.
This introduces an own QPA plugin for KWin. QtWayland's plugin is not
a good solution for KWin as QtWayland is meant for Wayland clients and
not for a Wayland server. Given that it makes more sense to have a very
minimal QPA plugin which supports the use cases we actually have.
With our own QPA plugin we should be able to improve the following
areas:
* no need to create Wayland server before QApplication
* Qt::BypassWindowManagerHint can be supported
* no workaround for creating OpenGL context in main thread
* sharing OpenGL context with Qt
* OpenGL context for Qt on libhybris backend
The plugin supports so far the following features:
* creating a QPlatformWindow using KWayland::Client (ShellSurface)
* creating a QPlatformBackingStore using a ShmPool
* creating a QPlatformOpenGLContext with Wayland::EGL
* or creating a QPlatformOpenGLContext which shares with KWin's scene
* creating a QPlatformScreen for each KWayland::Client::Output
* QPlatformNativeInterface compatible to QtWayland
Overwrite the platform name through the environment variable and ensure
that the plugin is not picked in non-kwin Wayland sessions as that puts
kglobalaccel5 into a crash restart loop.
BUG: 349911

As the loading of the plugin must happen after InputRedirection is
fully created a dedicated init method is added to InputRedirection.
