684b4b635e Use more traditional doxygen style
Summary:
So far we were following a bit unique and rare doxygen comment style:

    /**
     * Contents of the comment.
     **/

Doxygen comments with this style look balanced and neat, but many people
that contribute to KWin don't follow this style. Instead, they prefer
more traditional doxygen comment style, i.e.

    /**
     * Contents of the comment.
     */

Reviewing such changes has been a bit frustrating for me (so selfish!)
and for other contributors.

This change switches doxygen comment style in KWin to a more traditional
style. The main reason for doing this is to make code review process easier
for new contributors as well us.

8af2fa73dc 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.

The new class is responsible for parsing EDID blobs. It has pretty
straightforward API: you hand blob data to the constructor and after
that you're ready to query parsed data, e.g. physical size, etc.

c898f96df3 [platforms/drm] EGLStream DRM Backend Initial Implementation
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.

22a441e071 [platforms/x11] Force glXSwapBuffers to block with NVIDIA driver
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
in 2015 (see bug 346275, commit
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.

7b13393b64 [platforms/wayland] Multi output support
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.

d9c79e3627 [platforms/drm] Fix software cursors with drm backend
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.

cbbe94d769 Restrict available supported compositors based on first initialized one
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.

3dc22d7d88 [platforms/hwcomposer] Add scaling support
Summary:
Despite plasma frameworks doing it's own scaling with fonts, it's been
requested to use kwin/wayland scaling.

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

Config format is
[HWComposerOutputs][0]
Scale=N

The 0 is to map similarly to DRM and support multi-screen, but with a
screen index
rather than a UUID based on EDID.

Because we don't support multi screen this is always 0 for now.

Test Plan: Ran with the config value unset and with the config value at
Scale=3.

062dfefafe [platforms/hwcomposer] Port to AbstractOutput
Summary:
This gives us XdgOutput support a requirement now that wayland server
reports that we support it and Qt5.12 then expects it to be sent.

It also provides an easy starting point for supporting wayland scaling
and a slight step towards multi-output.

Test Plan:
Ran on phone. Got output. Turning screen on and off works.
The double tap doesn't work great, but that was true before
(via bshah's hack to build on the current state)

To make the code more consistent, this change updates the style of all
doxygen comments to the last one.

5d63b9c05b Fix flickering with Qt 5.12
Summary:
Mesa requires XESetWireToEvent xlib callbacks to be called
when DRI2 is used. This is done by the GLX integration in
the Qt's xcb plugin, but Qt 5.12 initializes the GLX integration
only when required, e.g. when a window with OpenGL support is
created or when availability of OpenGL is checked.

So force initialization of the GLX integration by calling
QOpenGLContext::supportsThreadedOpenGL().

Test Plan:
Autotests succesful with two exceptions: The decoration input test fails on
testDoubleTap, row topLeft. This is to be expected because now the
ScreenEdgeInputFilter captures the event at position (0,0) before the
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

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.

304528e80b [platforms/fbdev] Attempt to set the framebuffer color layout on the framebuffer device
Summary:
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.

5b4eb80c8f Set specific edge cursor shape when resizing
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)

Test Plan:
Resized some windows (on X and on Wayland)
Correct icon appeared on Adwaita
Existing icon appeared on Breeze

69afe4d266 Update seat's timestamp after waking up screen through double tap
Summary:
The drm platform has a special handling for touch events while the
screen is in dpms. All touch events are filtered out, but a double
tap wakes up the screen.

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
have "fake" events (e.g. smart phone in pocket) wake up the device.

Summary: TTYs are only available for seat0, so when starting a framebuffer kwin on seat1, it never draws, because drawing is always suspended, because it is being treated as not active

Test Plan: The framebuffer backend draws on seat1, and /dev/fb1 and when I switch back to my Weston greeter, (when it's also using the frame buffer,) it doesn't try to draw on top of it.

c44788889c [platforms/virtual] Make VirtualOutput non-copyable
Summary:
Qt objects are treated as identities so remove the copy constructor and
an assignment operator. See, http://doc.qt.io/qt-5/object.html#identity-vs-value

IIRC some Qt objects(like QImage) have copy constructor for implicit data sharing,
but VirtualOutput doesn't have anything to share.

Also, it [this patch] fixes a compiler warning:

```

68698b4201 [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.

82d2860469 [colorcorrection] Night Color - blue light filter at nighttime
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

Test Plan:
Manually with the workspace parts and added integration tests in KWin using
the virtual backend.

d4ba05a22f [autotests] Add tests for DRM platform plugin
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.

9df1744830 Support automatic screen rotation based on orientation sensor
Summary:
This change introduces an OrientationSensor class which wraps a
QOrientationSensor. The OrientationSensor is hold by Screens and gets
enabled if Screens knows about an internal (e.g. LVDS) display which
supports rotation. In addition the OrientationSensor holds an KSni to
enable/disable the automatic rotation support.

The drm platform plugin is adjusted to make use of the OrientationSensor.
The API is defined in a way that this can also be implemented on other
platforms supporting rotation. Most important are hwcomposer and X11
standalone. The latter should be straight forward as rotation is provided
through XRandR. The former needs addition for rotation support first.

4bfeeb3084 [platforms/drm] Fix cursor hotspot for inverted landscape rotation
Summary:
This change fixes the hotspot calculation by introducing a dedicated
matrix to map the hotspot.

To better test the hotspot a small test application is added. The app
renders a red point at the cursor position and uses a cross for cursor
with the hotspot position being transparent. So if KWin renders the
cursor at the correct position a red point is visible in the center of
the cross. The test app supports several cursor hotspot positions:
 * center (default)
 * top left
 * top right
 * bottom right
 * bottom left

To switch between the variants press the space key.

Test Plan:
Rotated screen, used test app to verify the hotspot is
correct. Also scaled display, still correct

c9c26019a1 [platforms/drm] Move cursor dumb buffers to Output
Summary:
So far all outputs shared the same dumb buffer for the cursor image.
This doesn't work any more when screen rotation is enabled. For rotated
screens the cursor image per output is different. On some it might be
rotated, on some not.

To solve this problem the dumb buffers are moved from the DrmBackend to
the DrmOutput. The DrmOutput now creates the cursor images itself and
can rotate them if needed. Thus we get nicely transformed cursors.

Test Plan: Rotated screens, moved cursor around, image properly rotated

a7117e4304 Don't use the global KConfig object on the OpenGL freeze detection thread
Summary:
This is meant to address Bug 372114. The problem here is that the KConfig
object (and its derivatives), that the freeze detection thread needs to
record the freeze, are not thread safe. When it happens that the main
thread is in fact not frozen, it is possible that the two stomp on each
other's KConfig object.

The solution applied here is to use the KSharedConfig::openConfig
function, which is thread safe, on the freeze detection thread. As was
mentioned by Martin Flöser in the discussion, the thread needs to obey
the name of the main config file of KWin, which can change in the future.

As a secondary issue, this patch also turns off KCrash reporting for
aborts due to a freeze being detected. IMO it is not very user friendly
to still show a crash report to the user, even after this bug is fixed,
for the deliberate SIGABRT. Maybe a less intrusive notification could be
used to tell the user why effects are suddenly disabled?

I've been using kwin with this change for several weeks now and it makes
the restarts of kwin due to freezes unobtrusive. However, most (I would
say almost all) of these freezes are actually instances where the system
 is being slow after eg. screen resolution is changed.

Summary:
This change hooks up the drm plane rotate with the rotation requests
from KScreen. Our requests support more than what KScreen exposes in the
UI, that is all the flipped variants. I do not really understand what
the flip means, so this is not implemented yet.

Furthermore this only implements the visual rotation and not the input
rotation. This means mouse movement and touch input is currently broken
on a rotated screen.

Please note that the hardware I used seems to not support the vertical
rotation. I'm not sure whether my code works. On my system it just
results in atomic commit errors and we need to go back to a previous
working state. This is not yet implemented. I need to test the vertical

Summary:
A preparation step to support rotation of outputs. The idea is to rotate
using DRM directly and not add it to the compositors. With this change

of type HWC_FRAMEBUFFER, instead of 2nd layer being
HWC_FRAMEBUFFER_TARGET. Thanks to @NotKit on telegram for pointing this
out.

- Use sourceCropf instead of sourceCrop, as sourceCrop is legacy option.

33a4cf4050 [drm] Implement changing of modes
Summary:
This change hooks up the bits for changing the mode when a request to
change mode from kscreen is received. This includes:
 * setting new mode in DrmOutput
 * creating new buffers in SceneQPainter backend
 * creating new GbmSurface in SceneOpenGL backend

Room for improvement:
 * detect whether the new mode works and go back to old one if it fails

Test Plan:
Started both a QPainter/OpenGL session. Used kcmshell5 kscreen
to modify the resolution. Saw that it got applied, maximized a window to
verify it's correct. Changed back to original resolution. Verified it looked
good by maximizing a window.

Summary:
We want to translate by the monitor position, so that needs to be
the negative of the position.

But Kwin/KScreen treats 0 as the top of all monitors. GL treats 0 as
bottom, so that all needs inverting.

Hence this should be a positive y value for the viewport.

2e868c50df Create a dedicated X11Filter for Client sync events and move it to X11 platform
Summary:
On Wayland we have the sync disabled as it doesn't work properly. This
allows us to also move the sync event handling into the X11 standalone
platform.

The code is slightly refactored: instead of passing the event to each
Client, we search for the matching Client. For that the SyncAlaram struct
is added to public section of Client. The method to handle the sync
doesn't need the event any more and is moved from events.cpp to
client.cpp.

Run Xephyr+kwin_x11, resized a window and verified through
gdb breakpoint that the sync still works

Summary:
So far KWin does not know which Compositors the platform actually
supports. This results in KWin happily trying to use the OpenGL
compositor on fbdev or the QPainter compositor on hwcomposer although
that is obviously going to fail as the platform doesn't support this.

By adding a pure virtual method all Platforms can define what they
support. In a later step the Compositor can use this to create an
appropriate scene and also perform proper fallback handling in case the
scene creation fails.

47343fb8f7 [platforms/drm] Use a shared pointer for gbm_surface
Summary:
The gbm_surface is owned by the EglGbmBackend, but it's not the only one
using it. The DrmSurfaceBuffer is also using it and needs it to destroy
the gbm_bo. Now this can become a problem in the following situation:

* a page flip is still pending
* the EglGbmBackend destroys the gbm_surface

-> when the page flip happens the DrmSurfaceBuffer will try to destroy
the gbm_bo and crash as the gbm_surface is no longer valid. This
situation can happen when switching screens or when switching compositing
backend (OpenGL 2 -> OpenGL 3).

To address this problem a class GbmSurface is added which wrapps the
gbm_surface pointer. The EglGbmBackend creates and holds a shared pointer
to the GbmSurface and passes that one to the DrmSurfaceBuffer. So when
cleaning up the gbm_surface only the shared pointer is reset and in case
the DrmSurfaceBuffer still needs it, it can access it without problems.

* SceneOpenGL::Texture -> SceneOpenGLTexture
* SceneOpenGL::TexturePrivate -> SceneOpenGLTexturePrivate
* texture based code into dedicated files
* SwapProfiler code into dedicated files
* SwapProfiler only used in x11 variants
* Safety checks for OpenGL scene moved into the new plugin
* signal declared in SceneOpenGL moved to Scene, so that we don't need
to include SceneOpenGL in composite

535b107969 Move QPainter compositor into plugin
This change is similar to D7232 and moves the scene_qpainter into a
dedicated plugin. Compared to the XRender case it's more complicated as
the platform plugins need to implement a platform specific backend.

The base implementation for this part used to be in scene_qpainter. As
the idea is to completly move it away from KWin core it would be point
less to still have the backend definition in KWin core, but it cannot
be in the scene plugin as otherwise all platforms need to link the
plugin.

To solve this a new platformsupport subdirectory is added which contains
the scene platform backend as a static library. For the OpenGL scene such
a static library will also be required.

Summary:
KWin::updateXTime only delegates into the platform API where the method
is a no-op. The actual implementation is moved into the X11 standalone
platform as it uses QX11Info which is non functional except on the X11
standalone platform.

This change exposes a problem with timestamp handling: on Wayland the
X11 timestamp does not get updated at all, causing e.g. window sync not
work correctly (c.f. bug 374881). We cannot implement the updating in the
same way as QX11Info/Qt xcb platform does it as that would introduce a
blocking roundtrip to XWayland which is dangerous.

As a side-effect this change removes linking to Qt5::X11Extras in kwin
core as it's no longer needed.

The overlay window is only needed for the X11 based compositors. Given
that it is better suited in the X11 platform. Unfortunately it is not
possible to completely move it into the platform plugin as it is still
referenced in KWin core (e.g. SceneXRender). Due to that the
OverlayWindow in KWin core is turned into a pure virtual class with the
implementation being moved into the plugin.

The platform API gains a new virtual factory method which is only
implemented in the X11 platform.

ea5d611de1 Require C++14
Summary:
KWin already used C++14 constructs in a conditional way. This doesn't
make much sense today, it's better to just require C++14.

For KWin only gcc and clang are currently compilers of relevance. Gcc
supports C++14 since version 5 and defaults to C++14 since 6.1 [1].
Clang supports C++14 since version 3.4 [2].

An overview of compiler support in various distributions:
* Debian stable (stretch): gcc 6.3, clang 3.8
* Debian oldstable (jessie): 4.9, clang 3.5
* Ubuntu 17.04: gcc 6.1, clang 3.8
* Ubuntu 16.04: gcc 5.3, clang 3.8
* openSUSE Tumbleweed: gcc 7.1, clang 4.0
* openSUSE Leap 42.3: gcc ?, clang ? [3]
* FreeBSD: clang >= 34 in ports
* Slackware 14.2: gcc 5.3

This overview shows that every distro out there has at least one
supported compiler which can still compile KWin with this change.

[1] https://gcc.gnu.org/projects/cxx-status.html#cxx14
[2] https://clang.llvm.org/cxx_status
[3] Sorry I fail to understand openSUSE's package repository.
    It seems that there is gcc 7 available, but gcc package is 4.8

06a558e3de [platforms/x11] Quit the OpenGL Freeze protection thread on shutdown
Summary:
Weird NVIDIA behavior fixup part 2. Now that we do no longer freeze when
NVIDIA decides to create an OpenGL error on startup
(aefb5f4dd9), we experience a new issue.
KWin is terminating (no idea why, [1]) and at the same time the OpenGL freeze
protection thread is still running. So far we did not terminate the
thread on shutdown and thus we hit an abort in Qt.

This change ensures that we properly terminate the thread on shutdown.

[1] My current theory is that games terminate KWin, common pattern of
bug reports is "steam".

BUG: 382283

4e9456a857 [platforms/x11] Fix incorrect screen edge approaching with switch desktop on window move
Summary:
There is a regression in WindowBasedEdge::soStopApproaching. Due to
only operate when the edge activates for pointer it is possible that
the cursor polling stays active. Explaining the situation:

1. Activate switch desktop when moving window
2. Start moving a window
3. Move mouse into the approach geometry
-> doStartApproaching activates as we are moving a window
4. stop moving window
-> doStopApproaching early exits as the position does not activate for
   pointer any more - we are not moving a window
-> cursor polling is still connected and whenever mouse enters edge
   approaching is started

The analysis shows that the check whether activates for pointer is wrong
in the case of stop approaching. If the edge started to approach, we also
need to stop approaching.

This change addresses the problem by turning the check into whether the
connection for cursor position update is set.

This is the third bug fix to the X11 screen edge handling after
introducing touch screen edges. This needs more manual testing by
everybody in the Plasma team who is still using X11.

a0571ccf84 [DRM plugin] Remember static kernel objects, amplify use of DrmCrtc
To get an image from KWin to the screen in the DRM pipeline we combine a CRTC,
an encoder and a connector. These objects are static in the sense, that they
represent real hardware on the graphics card, which doesn't change in a
session. See here for more details:
https://01.org/linuxgraphics/gfx-docs/drm/gpu/drm-kms.html

Until now we used DrmOutput as the main representation for such an active
rendering pipeline. I.e. it gets created and destroyed on hot plug events of
displays. On the other side we had no fixed representation of the static kernel
objects throughout the lifetime of KWin. This has several disadvantages:
* We always need to query all available static objects on an hot plug event.
* We can't manipulate the frame buffer of a CRTC after an output has been
  disconnected
* Adding functionality for driving multiple displays on a single CRTC (i.e.
  cloning) would be difficult
* We can't destroy the last frame buffer on display disconnect because the CRTC
  still accesses it and have therefore a memory leak on every display disconnect

This patch  solves these issues by storing representations of all available CRTC
and Connector objects in DrmBackend on init via DrmCrtc and DrmConnector
instances. On an hotplug event these vectors are looped for a fitting CRTC and
Connector combinations. Buffer handling is moved to the respective CRTC
instance. All changes in overview:
* Query all available CRTCs and Connectors and save for subsequent hotplug
  events
* Fix logic errors in `queryResources()`
* Move framebuffers, buffer flip and blank logic in DrmCrtc
* Remove `restoreSaved()`. It isn't necessary and is dangerous if the old
  framebuffer was deleted in the meantime. Also could reveal sensitive user
  info from old session.

Test Plan:
Login, logout, VT switching, connect and disconnect external monitor, energy
saving mode.

014afe1c05 [platformx/x11] Fix touch events for internal Qt windows
Summary:
To have touch events working we need to do memory layout changes on the
xcb events. This is fine for identifying the touch events which should
trigger the screen edge. But when passed on to Qt to have QtQuick windows
(e.g. Alt+Tab) handle the touch events, this results in a problem:
Qt itself does also the memory movement and then the movement is double
and touch events break.

To prevent this problem an RAII class is added which moves the memory in
the ctor and moves it back in the dtor. So during KWin's processing it
has the right memory layout and later on in Qt's processing it has the
proper "wrong" layout which Qt can fix again.

Test Plan: Touch events in Alt+Tab work

eec6afe6f5 Don't map screenedge approach window if edge is only used for touch
Summary:
Another regression from enabling touch support on X11.
The approach window for pointer input gets unmapped as soon as the mouse
enters the window. This ensures that mouse motion events are not stolen
from other applications. But with the touch events we did not even react
on the enter event if it's not activated for pointer. The result was an
area around the screenedge being blocked for pointer input.

This change only creates and maps the approach window if the edge is
activated for pointer input.

aa6c8f8116 Add support for activating screenedges through touch swipe gestures
Summary:
Each Edge creates a SwipeGesture for touch activation. The swipe needs to
be a single finger starting from the edge into the screen for at least
20 %. The SwipeGesture and GestureRecognizer is extended to support the
use cases of the touch screen edge swipe.

New features supported by the gesture system are:
 * minimum and maximum position
 * a minimum delta for the swipe
 * progress signal based on the minimum delta
 * starting a swipe with a start point

The Edge has the progress signal connected to its approach signal, thus
visual feedback is provided through the screen edge effect.

The screen edge system supports touch only for the edges (corners are
too difficult to activate on touch screens). At the moment the following
features are supported:
 * screen edge show/raise of windows (e.g. auto hidden panels)
 * trigger the configured action
 * trigger the configured callback function (e.g. script)

In future it might make sense to add a touch specific configuration
action to support different actions for screen edges activated by mouse
and touch.

BUG: 370323

Test Plan:
configured a screen edge and triggered through touch,
added an auto-hiding panel and triggered through touch

a347d009d1 [DrmBackend] Straighten out EGL surface buffer release logic on page flip
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

65ddd32d1a Split modifier only handling into a dedicated InputEventSpy
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:
InputRedirection has a workaround to add a connect on a QAction which
is used for a global shortcut. This is specific to the X11 platform as
the xtime needs to be updated.

This change adds a new virtual method to the Platform and moves the
implementation into the X11 standalone platform. Thus it does no longer
gets called on Wayland.

f906e21f3d [platforms/hwcomposer] Support for hwcomposer 1.4 and 1.5 version
Summary:
HWcomposer version 1.4 introduced setPowerMode, which replaces the
blank(). This adds support for it. There are various code paths
possible,

- If KWin is built against hwcomposer 1.3 headers, then setPowerMode
code is not compiled in, and it will use blank to turn display off.

- If KWin is built against hwcomposer 1.4 headers, it will have
setPowerMode code path compiled in. It will be used only on devices with
1.4 and 1.5 version of hwcomposer.

This is slightly insane, because Android can report hwcomposer 1.5 even
when headers are of 1.4 version..

Test Plan: Tested this on Nexus 5X which reports 1.5 version of hwcomposer

Summary:
This supports "grabbing" the pointer on right ctrl key just like on X11.
If the Wayland server supports pointer constraints protocol, the nested
Wayland compositor creates a confined pointer if the right ctrl key is
pressed.

On another right ctrl press the (active) constraint gets removed again.

To indicate the current state the window title gets updated. This also
implements window title support for the first time.

This change implement T4604.

d1de6899fd Move querying the egl extensions into the AbstractEglBackend
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.

Test Plan:
Tested nested kwin on Wayland, still works, extensions shown
in debug console

7b464cf284 Support interactive window selection through the Platform
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.

Test Plan: Killing of X11 windows is still possible

Summary:
And finally nothing inside libkwineffects, libkwinglutils,
libkwinxrenderutils and kwineffect and kwin core uses KWin::display.
We are finally XLib free!

This change drops KWin::display and removes the include to QX11Info from
kwinglobals.h. And the libraries no longer need to link X11Extras.  Due
to that removal a few seeming unrelated changes are required to add the
include where needed and linkage to X11Extras.

The biggest change is to x11 platform plugin which still needs the
display and caches it in the Platform and passes it to various places in
a way that the code doesn't need to be adjusted.

d7fa827644 Pass function ptr to resolve glFunctions to initGL
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.

Test Plan: nested KWin with OpenGL/EGL still works

querying can be moved there.

In order to simplify the extensions can be stored in the OpenGLBackend
which also provides the convenience check as before.

The egl platforms should also be adjusted to query in that way and
remove it from the kwinglutils.

There is still a usage of the glxextensions inside kwinglutils to
resolve one function. That should also be moved into the platform.

e90e596864 Add way to hide/show cursor in Platform
Summary:
Some platforms support to hide and show the cursor. This will be needed
by e.g. the zoom effect which currently only provides this functionality
on X11.

This change introduces a new method in the Platform to hide and show the
cursor. The methods need to be called balanced and the implementation
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
far the DRM and X11/Standalone platforms implement the required
functionality, though other platforms probably could implement as well.

19147f5f85 [platformx/x11] Add a freeze protection against OpenGL
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

ea52ef9e57 Add a PlatformCursorImage to Platform and EffectsHandler
Summary:
There are several effects (screenshot, zoom) which need access to the
cursor image and cursor hotspot. So far these effects used X11
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.

Test Plan:
Zoom effect tested on Wayland, now gets the proper cursor icon.
X11 functionality not yet tested.

66d1a0cc7a Add event filter for key press/release events while KWin grabbed keyboard on root window
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.

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

997cf97c9f Atomic Mode Setting / Universal Plane preliminary support
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.

What needs to be done next: Make it possible to transfer EGL buffers
directly to planes and implement logic for deciding about using a plane
or not for a specific buffer.

You can read more about it on LWN:

9c5f972c6a Forward x11 raw pointer buttons to PointerInputRedirection
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.

Test Plan:
Pressed meta, clicked, scrolled, released meta: launcher
did not open. Pressed meta, released meta: launcher opened

a67ccc3529 [platforms/drm] Pass ownership of gbm_device to Platform
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

4e7392b907 [platforms/virtual] Pass ownership of gbm_device and drm fd to Platform
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.

2a8ab547e1 Move X11Cursor into the x11standalone platform plugin
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.

c04e764369 [platforms/hwcomposer] Reset old brightness when turning screen back on
Summary:
Now powerdevil can adjust brightness using leds subsystem, however, kwin
as well sets brightness to 0 for turning off screen and 0xff when
turning screen back on. This resets the brightness set by the powerdevil
to 100%.

As a solution now kwin listens to brightnessChanged dbus signal of
brightnesscontrol and book-keeps the changed brightness, if screen is
turned off it sets brightness to 0 and when turning screen on, it resets
to old brightness.

If powermanagement service doesn't appear on dbus by default it restores
100% brightness.

Test Plan:
Appearantly this still doesn't work as-it-is on phone, because powerdevil
doesn't emit brightnessChanged dbus signal because of bug in the driver of
backlight control, driver doesn't seem to trigger uevents for changes in
backlight. But with hack in powerdevil to emit brightnessChanged when setting
brightness, this works

44e37aacdf Set initial count of screens before calling Screens::init
Screens::init sets up a Qt::QueuedConnection connect from countChanged
to changed. This means that when first setting up the connection a
changed signal will be delivered in the next event cycle. This can mess
with other code. E.g. WaylandServer recreating outputs which can make
Xwayland crash or KWin internally crash.

To solve this problem we just need to make sure to set the output count
to the initial value before performing the init.

996ee34e14 Remove the unredirect fullscreen windows functionality
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.

Test Plan:
Compiles, cannot really test as I am an Intel user who never
had that working.

b1f6d4b8ba [platforms/x11-windows] Delay x11 event processing till Workspace is started
If the event processing is started before everything is fully started
it can happen that we have "evil" events which may crash either Xwayland
or KWin itself. E.g. if the nested window is too large, the window
manager on the host X-Server will request a resize. If the backend does
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.

56ce6689fd [platforms/virtual] Use rendernode or vgem device if available for egl
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.

9d7ef58b2b Support restarting the OpenGL compositor on Wayland
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.

d0c488f4a2 Announce output changes to Wayland for platforms not handling outputs
Summary:
Most platforms like the nested and virtual do not handle the outputs
themselves and WaylandServer announces the Outputs to Wayland.

So far this was static: at startup it got announced once to 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.

Test Plan: Auto test added which verifies this for the virtual platform

If it's not possible to create a buffer to blank the output, KWin won't

To support this DrmOutput::blank and DrmOutput::init return bool to

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
