01c1870e9d Support dynamic output enabling/disabling from KScreen
Summary:
We need to keep the DrmOutput object to still have the
WaylandOutputDevice.

Screens currently start off enabled as before.

In order to keep KWin to have a correct index based list of screens we
need to store a second vector of currently enabled outputs for the
screens interface.

Test Plan:
Had dual screens.
Disabled/Enabled each one through the kscreen KCM

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.

Summary:
While KWin gained support for changing modes it did not yet forward it
to the Wayland OutputInterface. This change implements this missing todo
by finding the matching mode and marking it as current.

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

c06c234778 [platforms/drm] Properly adjust cursor position on a rotated output
Summary:
This change refactors the way how the cursor position on a screen is
calculated. It is changed to a matrix multiplication with the
adjustments for the rotated screen just being additional steps added to
the matrix.

With this calculation I got correct positions for all variants of
scaled, rotated and differently positioned outputs.

26cdfd317f [platforms/drm] Restore previous mode if an atomic test fails
Summary:
When KWin successfully presents a new mode, it stores the current state
as the last working mode. If a new modeset is requested and the atomic
test fails, all is undone and reverted to this last knowing mode.

Currently included are:
 * the mode
 * global position
 * transformation

This is only done on a modeset not when going to DPMS.

Test Plan:
Selected the not working vertical rotation and nothing bad
happened.

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.

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.

Split off GBM based buffers to a separate file, which gets only included,

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.

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:

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.

With this change configuring layout of connected screens in KScreen
