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:
So far wayland was used by internal clients to submit raster buffers
and position themselves on the screen. While we didn't have issues with
submitting raster buffers, there were some problems with positioning
task switchers. Mostly, because we had effectively two paths that may
alter geometry.
A better approach to deal with internal clients is to let our QPA use
kwin core api directly. This way we can eliminate unnecessary roundtrips
as well make geometry handling much easier and comprehensible.
The last missing piece is shadows. Both Plasma::Dialog and Breeze widget
style use platform-specific APIs to set and unset shadows. We need to
add shadows API to KWindowSystem. Even though some internal clients lack
drop-shadows at the moment, I don't consider it to be a blocker. We can
add shadows back later on.

This change converts all usages of 0 and NULL literal to nullptr. Even

This patch further refines output management.
We go now through AbstractWaylandOutput virtual functions to enable and
disable outputs.
Dpms changes and enablement switches use separate code paths at start in the
Drm backend code since they are similar but not the directly same. Common code
is shared though, functions are renamed accordingly.
Asserts have been put in place to better understand and check the control
flow. A seemingly unnecessary call to DrmOutput::pageFlipped on reactivation
after Vt switch has been removed to allow for that.
In future patches we need to look additionally at the legacy mode switching
code path which was and is still not working and better handling of the
current monitor Dpms state. For example a monitor being switched off is not
properly acted on and the workspace still expanded.

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.

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.

Since QPA only performs off-screen rendering, it does not require an EGLConfig
that supports any particular surface type. Currently it requests a config
supporting window surfaces, however the EGLDeviceEXT platform, which is the
basis of the EGLStream back-end used with the proprietary NVIDIA driver, does
not support such surfaces resulting in eglChooseConfig not returning any valid
configs when that back-end is in use. Since QPA doesn't actually create any
window surfaces, it should be fine to remove this restriction to allow it to
initialize properly with the EGLStream back-end.

Summary:
The NVIDIA implementation of glXSwapBuffers will, by default, queue up
to two frames for presentation before blocking. KWin's compositor,
however, assumes that calls to glXSwapBuffers will always block until
the next vblank when rendering double buffered. This assumption isn't
valid, as glXSwapBuffers is specified as being an implicit glFlush,
not an implicit glFinish, and so it isn't required to block. When this
assumption is violated, KWin's frame timing logic will
break. Specifically, there will be extraneous calls to
setCompositeTimer with a waitTime of 0 after the non-blocking buffer
swaps, dramatically reducing desktop responsiveness. To remedy this,
a call to glXWaitGL was added by Thomas Luebking after glXSwapBuffers

8bea96d701). That glXWaitGL call is
equivalent to a glFinish call in direct rendering, so it was a good
way to make glXSwapBuffers behave as though it implied a glFinish
call.
However, the NVIDIA driver will by default do a busy wait in glFinish,
for reduced latency. Therefore that change dramatically increased CPU
usage. GL_YIELD can be set to USLEEP (case insensitive) to change
the behavior and use usleep instead. When using the NVIDIA driver,
KWin will disable vsync entirely if GL_YIELD isn't set to USLEEP
(case sensitive, a bug in KWin).
However, the NVIDIA driver supports another environment variable,
__GL_MaxFramesAllowed, which can be used to control how many frames
may be queued by glXSwapBuffers. If this is set to 1 the function
will always block until retrace, in line with KWin's expectations.
This allows the now-unnecessary call to glXWaitGL to be removed along
with the logic to conditionally disable vsync, providing a better
experience on NVIDIA hardware.

Summary:
This patch rewrites large parts of the Wayland platform plugin, in order to
facilitate the testing of multi output behavior in nested KWin sessions.
For that a new class WaylandOutput is introduced, which is based on
AbstractOutput and by that shares functionality with our virtual and DRM
platform plugins.
The EGL/GBM and QPainter backends have been remodelled after the DRM one,
sharing similiarities there as well now.
Pointer grabbing has been rewritten to support multiple outputs, now using
pointer locking instead of confining and drawing in this case onto a sub-
surface, which get dynamically recreated in between the different output
surfaces while the cursor is being moved.
Window resizing is possible if host supports xdg-shell, but currently the
mode size does not yet fill the new window size.
The number of outputs can be set by command line argument `--output-count`,
scaling is also supported by setting the argument `--scale`.
Further steps could be:
* Enabling automatic fill of resized windows via Wayland mode change
* Multiple diverging initial sizes and scale factors for mulitple outputs
**Watch it in action:** https://youtu.be/FYItn1jvkbI
Test Plan: Tested it in live session.

Summary:
If hardware cursor support is not available when using the drm backend for
Wayland compositing, the software cursor texture will not be updated when the
cursor image changes, and it will still be drawn when no cursor image is set
(such as when running a full-screen game). Furthermore, the drmModeSetCursor
and drmModeMoveCursor functions will still be unnecessarily called when the
cursor is moved or hidden.
To correct this, SceneOpenGL should connect Platform::cursorChanged as opposed
to Cursor::cursorChanged to its texture update function, as only the former
will be emitted when the cursor is updated and the compositor should check if
the cursor is hidden and the software cursor image is not null before rendering
it. DrmBackend::moveCursor and DrmBackend::hideCursor should also return
immediately if using a software cursor.

Summary:
On Wayland we cannot switch from OpenGL to QPainter compositor as this
would break any running OpenGL application. KWin registers it's
EGLDisplay to Wayland and without OpenGL this doesn't make sense any
more. We are not able to render OpenGL buffers in the QPainter
compositor.
While it's theoretically possible to switch from QPainter to OpenGL it
doesn't make any sense for the same reason. Any running OpenGL
application would be using llvmpipe and could not be switched to proper
OpenGL.
This change stores the selected compositing type in Platform and the
implementations can use it to restrict the supported compositors. On X11
we don't need this, all other Platforms implement the restriction. Thus
it's no longer possible to switch the backends at runtime.
Test Plan:
Adjusted tests run, no runtime test as gui doesn't support
switching to QPainter anyway.

Summary:
Using the Wayland protocol for OpenGL is no longer used or useful. KWin
internal windows only use OpenGL through QtQuick. We either have the
sharing context (KWin uses OpenGL for compositing) or we have the
QPainter compositor which also turns QtQuick to use software renderer.
Thus a situation where the Wayland platform context is useful doesn't
exist any more. Removing it helps getting the QPA plugin Wayland free.

with QPainter compositor.

Like DRM, when kscreen is not used, scale value is loaded from a config

The 0 is to map similarly to DRM and support multi-screen, but with a

Summary:
KWindowSystem provides a plugin interface to have platform specific
implementations. So far KWin relied on the implementation in
KWayland-integration repository.
This is something I find unsuited, for the following reasons:
* any test in KWin for functionality set through the plugin would fail
* it's not clear what's going on where
* in worst case some code could deadlock
* KWin shouldn't use KWindowSystem and only a small subset is allowed
to be used
The last point needs some further explanation. KWin internally does not
and cannot use KWindowSystem. KWindowSystem (especially KWindowInfo) is
exposing information which KWin sets. It's more than weird if KWin asks
KWindowSystem for the state of a window it set itself. On X11 it's just
slow, on Wayland it can result in roundtrips to KWin itself which is
dangerous.
But due to using Plasma components we have a few areas where we use
KWindowSystem. E.g. a Plasma::Dialog sets a window type, the slide in
direction, blur and background contrast. This we want to support and
need to support. Other API elements we do not want, like for examples
the available windows. KWin internal windows either have direct access
to KWin or a scripting interface exposed providing (limited) access -
there is just no need to have this in KWindowSystem.
To make it more clear what KWin supports as API of KWindowSystem for
internal windows this change implements a stripped down version of the
kwayland-integration plugin. The main difference is that it does not use
KWayland at all, but a QWindow internal side channel.
To support this EffectWindow provides an accessor for internalWindow and
the three already mentioned effects are adjusted to read from the
internal QWindow and it's dynamic properties.
This change is a first step for a further refactoring. I plan to split
the internal window out of ShellClient into a dedicated class. I think
there are nowadays too many special cases. If it moves out there is the
question whether we really want to use Wayland for the internal windows
or whether this is just historic ballast (after all we used to use
qwayland for that in the beginning).
As the change could introduce regressions I'm targetting 5.16.
Test Plan:
new test case for window type, manual testing using Alt+Tab
for the effects integration. Sliding popups, blur and contrast worked fine.

So force initialization of the GLX integration by calling

Summary:
Current implementation of buildQuads assumes that corner shadow tiles
are always present:
const QRectF leftRect(
topLeftRect.bottomLeft(),
bottomLeftRect.topRight());
but that assumption is wrong. For example, if the default panel is on
the bottom screen edge, then the calendar popup won't have the
bottom-left shadow tile(at least on Wayland). Which means that the left
shadow tile won't be visible because
topLeftRect.left() == bottomLeftRect.right().
Corner rectangles only have to influence height of the left/right tile
and width of the top/bottom tile. Width of the left/right tile and
height of the top/bottom tile should not be controlled by corner tiles.
Overall, this is how shadow quads are computed:
* Compute the outer rectangle;
* Compute target rectangle for each corner tile. If some corner tile is
missing, move the target rectangle to the corresponding corner of the
inner shadow rect and set its width and height to 0. We need to do
that to prevent top/right/bottom/left tiles from spanning over
corners:
{F6190219, layout=center, size=full}
We would rather prefer something like this if the top-left tile is
missing:
{F6190233, layout=center, size=full}
* Fix overlaps between corner tiles;
* Compute target rectangles for top, right, bottom, and left tiles;
* Fix overlaps between left/right and top/bottom shadow tiles.

* Ran tests;
* Resized Konsole to its minimimum size(on X11 and Wayland);
* Opened the calendar popup(on X11 and Wayland):

DecorationEventFilter can capture it. The autotest was adapted to take this
special case into account.
Also the lockscreen test fails, because the virtual output is currently missing
the physical size yet.

Summary:
In order to separate high-level properties of individual outputs from
hardware-specific ones and access these, introduce a new generic class Output.
Also make the DrmOutput class directly a child class of this generic class.
The long-term goal is to get rid of the Screens global object on Wayland and
instead directly work with Output objects on compositing level.
This should enable us long-term to do direct scanout to hardware planes, what
I predict needs this generic output representation at one point.
Test Plan: Manually.

Weston does something similar
https://cgit.freedesktop.org/wayland/weston/tree/libweston/compositor-fbdev.c#n315
...and it seems that the non-primary framebuffer devices start completely off. (the screen is off on my Displayport device, and the window for the second vga card in qemu is much smaller than the primary one, and all black for my qemu vm) .
In my testing, sending the ioctl FBIOPUT_VSCREENINFO with a *changed* &varinfo allows it to wake up, and turns on the screen.
doing FBIOGET_VSCREENINFO and then FBIOPUT_VSCREENINFO in my testing does not work.
I think really the values that end up getting changed are varinfo.transp.offset and varinfo.transp.length. at least on the qemu system, but in this patch I am aligning all of them for completeness, because the drivers might do it differently for qemu
Test Plan: This causes the window for /dev/fb1 (remote-viewer, and a qemu vm with two "VGA" (bochsdrm) cards) to resize from the smaller size when specifying it as the --fb-device on seat0, and kwin draws on the device.

Summary:
Instead of seeing the cursor <--> on the left edge you now see an icon
that looks like |<- .
This brings kwin decorations in line with GTK CSD icons.
In theory this is also useful to tell which window will resize in the
case of side-by-side windows (regardless of whether borders are on or
not). In practice with the adwaita icon theme I tested with it's not
very intuitive to realise which is which till you learn the icon.
Change is more involved than it should be as Qt::CursorShape doesn't
have these entries, and I don't want to shadow that enum internally or
have
to change kwin effect code.
Specifics depend on cursor icon theme if they are not present it will
fallback to the <--> icon. (Breeze does not have them currently)

Summary:
This problem appears if shadow corner tiles are too big and
some window has size smaller than 2 * shadowTileSize.
This change tries to address the problem above by exclusing
overlapping tile parts. If there are any two overlapping corners
then tile between them(top/right/bottom/left) is not rendered.
Also, because some corner tile parts can be excluded, corner tiles
are expected to be symmetrical(i.e. if we remove right half from
the top-left tile and left half from the top-right tile and
stick them together, they still look fine, there are no misalignments, etc).
Most shadows(e.g. shadows from Breeze) have such behaviour.
No tiles are overlapping

Due to the filtering out of the events the idle timers were not reset.
So if you only double tapped, the screen turned on, but not off again.
This change updates the timestamp after double tap, so that the idle
timers are restarted. All other events are still filtered out, to not

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.

With Wayland KWin needs to provide certain services, which were provided
before that by the Xserver. One of these is gamma correction, which includes
the - by many people beloved - functionality to reduce the blue light at
nighttime. This patch provides the KWin part of that. It is self contained,
but in the end will work in tandem with a lib in Plasma Workspace and a KCM
in Plasma Desktop, which can be used to configure Night Color.
* Three modi:
** Automatic: The location and sun timings are determined automatically
(location data updates will be provided by the workspace)
** Location: The sun timings are determined by fixed location data
** Timings: The sun timings are set manually by the user
* Color temperature value changes are smoothly applied:
** Configuration changes, which lead to other current values are changed
in a quick way over a few seconds
** Changes on sunrise and sunset are applied slowly over the course of few
minutes till several hours depending on the configuration
* The current color value is set immediately at startup or after suspend
phases and VT switches. There is no flickering.
* All configuration is done via a DBus interface, changed values are tested
on correctness and applied atomically
* Self contained mechanism, speaks directly to the hardware by setting the
gamma ramps on the CRTC
* Currently working on DRM backend, extensible to other platform backends in
the future
* The code is written in a way to make the classes later easily extendable to
also provide normal color correction, as it's currently done by KGamma on X

Summary:
The addition of the test infrastructure is motivated by the regressions
caused by adding mode switching and transformation support.
A contributing factor to these regression is the fact that the DRM
platform does not have any tests. It is difficult to test this code as
it needs to work with hardware, thus we cannot use the real DRM library.
Instead we need to use mocking.
This change sets up some first basic tests with the help of a mockDrm
library. In order to better test the code as units the Drm classes are
slightly refactored. Most importantly the dependency to DrmBackend is
removed wherever possible and replaced by a simple int fd which is mostly
the only element used by the classes.
This first test introduces basic testing of a DrmObject. It is intended
to extend this to at least also test DrmPlane as a central piece of our
Drm platform plugin. This will also extend the tests of DrmObject.
