To successfully build kwin needs 13e6459a3baeebe6a7b594efd995b88f6dd7524e
in kdecoration. Otherwise it fails with: "previewclient.h:93:11: error:
'QSize KDecoration2::Preview::PreviewClient::size() const' marked
'override', but does not override QSize size() const override;"
So this is not a new requirement but just an update to the build system
to reflect the actual requirements.
Test Plan: Builds fine with the newly required version

Summary:
The ClockSkewNotifier provides a convenient way for monitoring system
clock changes. One of the key ideas was to hide platform details from
users of the class. This allows us to add a QTimer fallback path for
operating systems that don't provide anything to detect system clock
changes.
In long term, I would like to move the new class to Frameworks.

Summary:
Currently kwin opens a second ICE connection to ksmserver in order to
tell the state of kwin's whether we're logging out and saving clients or
not.
This requires that kwin launches after ksmserver to have the connection
which is a dependency I want to break.
Practically this code is already ksmserver specific as it relies on some
custom code that sends the first saveState request to kwin first.
Instead we can replace it with a bespoke IPC over DBus and siplify the
code both end. This will allow several other future enhancements that we
want with regards to handling the session state, as well as make an
effort platform agnostic session management, as well as cleaning up some
complex code.
Ksmserver calls into kwin, rather than having kwin watch ksmserver state
to allow us make sure it's race free.

Summary:
The EGL platform might go away at any time through reconfiguration or because
of a graphic error. KWin then resets the graphics. The dmabuf implementation
must respect that and recover from a graphics reset by recreating all EGL
images for existing buffer.
This assumes that we won't change our graphics API mid-session and that
supported plane and modifier configuration stays constant.
In practise we remember all current dmabufs in a single map and only remove
them if the client did destroy the resource.

Summary:
Currently each managed X11 client is represented with an instance of
Client class, however the name of that class is very generic and the
only reason why it's called that way is because historically kwin
was created as an x11 window manager, so "Client" was a sensible choice.
With introduction of wayland support, things had changed and therefore
Client needs to be renamed to X11Client in order to better reflect what
that class stands for.
Renaming of Client to X11Client was agreed upon during the last KWin
sprint.
Test Plan: Compiles, the test suite is still green.

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.

Summary:
The screenlock fails on X11 if it can't grab the keyboard.
We can't nicely solve the generic case. We can solve the common case of
a kwin effect being active.
It's not critical, arguably not even desirable to have these effects
persist after the screen is locked through an external trigger. We can
just close the effect early.
Key grabs have to be relased early before the close animation completes
so that the locker doesn't have a race based on animation times.
It's not ideal, but no worse than the current state for not much work.

move all Wayland specific parts of AbstractOutput into a new subclass
AbstractWaylandOutput and let the outputs of our Wayland backends inherit

This should allow us to get rid of the Screens class later on.

Summary:
This is the initial implementation of a DRM backend based on the EGLDevice,
EGLOutput, and EGLStream extensions, supporting NVIDIA graphics hardware using
their proprietary driver. The new backend will be used if the environment
variable KWIN_DRM_USE_EGL_STREAMS is set. On initialization, it will attempt to
create an EGLDevice based on the DRM device currently in use and create
EGLOutputs and EGLStreams for any attached displays. These are used to control
presentation of the final composited frame. Additionally, it will register the
wl_eglstream_controller Wayland interface so that native EGL windows created by
clients can be attached to an EGLStream allowing buffer contents to be shared
with the compositor as a GL texture.
At this time there are two known bugs in the NVIDIA driver's EGL implementation
affecting desktop functionality. The first can result in tooltip windows drawn
by plasmashell to contain incorrect contents. The second prevents KWayland from
being able to query the format of EGLStream-backed buffers which interferes
with the blur effect. Fixes for both of these are currently in development and
should appear in an upcoming NVIDIA driver release.
Additionally, hardware cursors are currently not supported with this backend.
Enabling them causes the desktop to intermittently hang for several seconds.
This is also likely a bug in the NVIDIA DRM-KMS implementation but the root
cause is still under investigation.
Test Plan:
On a system with an NVIDIA graphics card running a recent release of their
proprietary driver
* Ensure the nvidia_drm kernel module is loaded with the option "modeset=1"
("# cat /sys/module/nvidia_drm/parameters/modeset" should print "Y")
* Ensure EGL external platform support is installed
https://github.com/NVIDIA/eglexternalplatform
* Ensure KWin was build with the CMake option
KWIN_BUILD_EGL_STREAM_BACKEND=ON (this is the default)
* Start a plasma wayland session with the environment variable
KWIN_DRM_USE_EGL_STREAMS set
* Ensure output from KWin OpenGL initialization indicates the NVIDIA EGL
driver is in use (as opposed to Mesa / llvmpipe).
* Desktop should be fully functional and perform smoothly.
