12886cf442 Be consistent about touch point id type: use qint32
Summary:
There is no point in using quint32 and casting back and forth in numerous places.
Fix a bunch of compiler warnings that we implicitly cast between signed and unsigned.
This makes things consistent with what we get from libinput.

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.

1892bd33f2 [platforms/drm] Refactor out Edid class
Summary:
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.

The main reason to extract EDID parsing code into a class is to clean up
drm_output.cpp a bit.

Test Plan: Compiles, the DRM platform still works.

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.

Summary:
Currently there is no any good reason for keeping ScopedDrmPointer;
providing our own deleter for QScopedPointer would make more sense.

Given that we already have type that acts as a scoped pointer for drm
objects we can improve it a bit and make simpler, e.g.

    DrmScopedPointer<drmModeConnector> connector;

is much simpler than

    ScopedDrmPointer<_drmModeConnector, &drmModeFreeConnector> connector;

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.

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.

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

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

b2d8bbec81 [platforms/drm] Rotate screen if requested from KScreen
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
rotation on my notebook, which should (in theory) support it.

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.

8ae37c420b Move SceneOpenGL into a dedicated plugin
Summary:
Unfortunately a rather large change which required more refactoring than
initially expected. The main problem was that some parts needed to go
into platformsupport so that the platform plugins can link them. Due to
the rather monolithic nature of scene_opengl.h a few changes were
required:
* 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

Test Plan: Nested OpenGL compositor works

After changing the output configuration, the client expects that it is informed

Since we don't track if a setting failed yet, send the applied() signal regardless.

01ddbe7d75 Make AbstractEglBackend a QObject
Summary:
Several of the subclasses are already derived from QObject.

The main reason is that the class should be moved out of KWin core in
order to move the OpenGL scene into a plugin. As Compositor calls into
the AbstractEglBackend to unbind the wayland display this creates a
problem which is easily solved by turning the AbstractEglBackend into a
QObject and connect to the signal emitted by the Compositor.

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.

Test Plan: SceneQPainter test still passes, nested compositor still works

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.

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

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.

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.

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:

Screens::init sets up a Qt::QueuedConnection connect from countChanged

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

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.

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.

Please note that right now the drm platform's rendering does not

b5b2adc5a2 [platforms/drm] Only show cursor if a pointer device is available
Summary:
When the pointer device gets plugged off the cursor is hidden, when
a pointer device gets plugged in the cursor is shown again.

This allows to easily turn a tablet into a proper system by showing
the cursor only when it makes sense.

Test Plan: Tested on exopc with external mouse

2bff90976e Move backends/ to plugins/platforms/
Summary:
Source code reorganization:
The base class AbstractBackend got renamed to Platform, thus the
"backends" are "platforms" now. As they are plugins they should go
together with other KWin plugins which are nowadays in the folder
plugins.

So new location is plugins/platforms/
