c8cd474acd [platforms/drm] Explicitly request event context version 2
Summary:
Libdrm 2.4.78 introduces a version 2 and if KWin gets built against it
our code would break. Given that this change is for Plasma/5.8 branch.

Closes T5839

0dac5d6bfe Add scaling to DRM backend
Test Plan:
For the first time, actually plugged in my high DPI laptop.
Tested both 1x and 2x windows on 2 real displays one high DPI, one normal

9a582f6dbe Remove unused method
Summary:
This isn't used and if it was would give the wrong value.
Actual correct size can be determined via Screens object.

Test Plan:
Grepped it's not overriding anything
Compiles

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:

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
issues.

cd9a0afafa [platforms/drm] Properly handle case that mapping the blank buffer fails
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.

BUG: 365242
FIXED-IN: 5.7.2

Test Plan: No hardware to reproduce the condition

7ea84cd346 [platforms/drm] If mapping a DrmBuffer for a cursor fails, fallback to software cursor
Summary:
So far the drm platform did not verify whether creating and mapping a
DrmBuffer for a cursor works. This could result in a crash in the worst
case.

This change verfies whether mapping the two cursor buffers works, if
not software cursor is enabled. The code is adjusted to ensure that
none of the cursor buffers is accessed in case software cursor are
enabled.

Please note that right now the drm platform's rendering does not
support software cursors. Thus currently this change results in no
cursor at all. This will be addressed by following patches.

BUG: 364740
FIXED-IN: 5.7

Test Plan:
Verfied that it properly falls back to software cursor,
but could not verify that the crash is actually fixed.

f5b83d18b8 [platforms/drm] Apply new global position on DrmOutput for a changeset
Summary:
When we get a configuration request, we also need to update the global
position on the DrmOutput, otherwise Wayland will know about the new
position, but KWin internally does not.

In addition we also need to trigger the changed signal on KWin::Screens,
so that internally code can react on the change.

With this change configuring layout of connected screens in KScreen
does work also in KWin.

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/
