74b1fb0ab5 backends/drm: round refresh rate values from KScreen configs
The implicit cast effectively rounds the value down, which make the

A better fix would be to use integers instead of floating point numbers
but that needs to happen in KScreen.

ca6fcbb2a1 backends/drm: make finding connector<->crtc combinations more efficient
Encoders are not really relevant for the test result, except that one of
the encoders for the connector must be compatible with the crtc.
The kernel usually exposes only a single encoder per connector for this
reason, but if a driver exposes multiple then that means KWin will do a
lot more tests than is necessary.
In order to prevent that from happening, do fewer syscalls and simplify
code, only check supported encoders once per connector.

Fix force xrgb 8888
19c471405e7eb4b6026db24d776d205125dbc013 introduced a regression if
there are two gbm backend and the backend fail to choose drm format.

This fix does two things:
1. Current buffer format should not be reset after create new buffer,
   otherwise current.format may just be empty after resetOutput.
2. force xrgb 8888 need to be set on the primary backend.

352e92e32f Support global defaults for input devices
This adds support for reading values from a "Libinput/Defaults" group in
the input config file. This allows specifying global defaults for
devices, that are preferred over the libinput defaults. Because of the
cascading mechanisms of KConfig, this then allows distributions and
hardware vendors to supply system-wide defaults for devices.

0319a66ead Refactor libinput::Device::ConfigData
Rather than an awkward combination of template functions, function
pointers and multiple calls to almost-the-same-but-not-entirely
functions, make ConfigData itself a template and use type erasure to
store them in the config map. This makes the data object aware of its
type and allows us to specialise the reading of config values through
template specialisation. It also removes the need for multiple
constructors and setters in the ConfigData object.

The fixed size of 1080p makes windows change their size and place. To

84690a0de6 scenes/opengl: Move copying front buffer to back buffer to X11 specific code
On X11, if buffer age is unsupported, kwin can do some quirks like
copying parts of the front buffer to back buffer to avoid repainting the
whole screen.

Currently, the copying is performed in the opengl scene, which is not
perfect because it makes the scene responsible not only for painting the
scene but also some low level platform specific shenanigans.

This change moves the copying step to the glx and egl backends. It
simplifies the opengl scene, makes it less overloaded and more open to
changes, but it also duplicates code, which is not ideal. However, given
the de-facto deprecated state of the X11 platform, it's sort of acceptable
as the main focus is now on wayland session and the things that are
needed to make it fly as expected.

9f93358bc1 backends/drm: Notify about failed frames if there are actually pending frames
In case a modeset needs to be performed, the drm backend will test all
pipelines to ensure that new mode won't cause any bandwidth issues on
other outputs, etc.

To do that, it may delay presenting frames. If the new configuration
doesn't work, it needs to notify about failed frames.

However, the relevant code that notifies the RenderLoop about failed
atomic commits doesn't check if there's actually a pending modeset
present.

When switching between VTs, systemd can revoke master permissions from
kwin. To make things even more trickier, kwin can try to present a frame
in that short time span.

b6b0af727d backends/drm: don't take crtcs from dpms disabled outputs
Fixes a crash I have with dpms + suspend, which was caused by the udev
event for updating outputs being called before the output got enabled
again. When DrmGpu::updateOutputs got called it removed the crtc from
the inactive output and then disabled the output afterwards. Instead,
only remove crtcs if an output is really disabled.
This also allows to generalize the logic for lease outputs, and could
in the future allow for faster dpms on/off switching.

7228e9aefd Unify beginFrame() and endFrame() hooks for OpenGL and QPainter backends
This unifies frame hooks for OpenGL and QPainter render backends. There
are a couple of reasons why it's a good idea - it provides one mental
framework to start painting a frame, the Compositor will be able to
start and submit frames. The last one is very cool because it gives the
Compositor more power over compositing.

Besides unifying frame hooks, this cleans up a bit the arg naming mess
in endFrame(). As is, "damage" and "damagedRegion" are very confusing
names. "damage" arg has been renamed to "renderedRegion," because that's
what it is. The renderedRegion arg specifies the region that has been
repainted by the Scene. It's different from the damagedRegion as that
one specifies the surface damage, i.e. the difference between the
current and the next frame, while the renderedRegion may include a
region that had to be repainted to repair the back buffer. The main
reason why we need renderedRegion is the X11 platform. On Wayland, it's
unused.

In the future, we will need to extend this api with output layers.

c68f7f13f3 backends/drm,wayland: require gbm
The ifdefs for have_gbm obfuscate the code unnecessarily - the drm backend
is not a great experience with qpainter, so in practice noone should ship
it without gbm anyways.

6d0cca5c7f Move all dirty region scene repaint scheduling to Scene
The Compositor contains nothing that can potentially get dirty and need
repainting.

As is, the advantages of this move aren't really noticeable, but it
makes sense with multiple scenes.

Backend parts are far from ideal, they can be improved later on as we
progress with the scene redesign.

bad5752110 platforms/drm: kill the EglStreams backend
The proprietary NVidia driver now supports gbm, which vastly improves the
user experience. For older devices that will not get gbm support dropping
EglStreams will likely not have a big impact as it has several session breaking
issues anyways.

By removing the backend a lot of logic can be simplified, most notably multi-gpu.

02bb276ebf platforms/drm: Move ownership of mode blob to connector mode
The main motivation behind this change is to move management of drm
blobs out of property wrappers in specialized wrappers to simplify state
management with blobs.

Connector mode blobs are created on demand.

7283c98f27 platforms/drm: disable unused resources on modesets
When we switch CRTCs it can happen that a CRTC would stay enabled yet has
no connectors anymore. In this case the kernel may reject our atomic commit,
which would cause the modeset to fail. To counteract that, properly disable
unused drm objects

a07aae8282 platforms/drm: delay presentation for modesets
Currently KWin is combining modesets with presentation, which causes problems
when multiple monitors are used and crtcs need to be switched around, because
taking away a CRTC from another output causes the driver to disable the
other output. In order to avoid such problems, delay presentation until
all pipelines are ready to present and then do a modeset with a single atomic
commit. To process the resulting page flip events properly this commit also
ports KWin to page_flip_handler2 and changes how the pageFlipped and
notifyFrameFailed signals are processed.

e2a0863843 platforms/drm: more dynamic crtc assignment
Hardware constraints limit the number of crtcs and which connector + crtc
combinations can work together. The current code is searching for working
combinations when a hotplug happens but that's not enough, it also needs
to happen when the user enables or disables outputs and when modesets are
done, and the configuration change needs to be applied with a single atomic
commit.

This commit removes the hard dependency of DrmPipeline on crtcs by moving
the pending state of outputs from the drm objects to DrmPipeline itself,
which ensures that it's independent from the set of drm objects currently
used. It also changes requests from KScreen to be applied truly atomically.

d89501a079 Move platform backends to backends directory
This improves file organization in kwin by putting backends in a single
directory.

It also makes easier to discover kwin's low level components for new
contributors because the plugins directory may come as the last place to
look for. When one hears "plugin", the first thing that comes to mind is
regular plugins, not low level backends.
