99b6f6150d [platforms/drm] Determine the supported transformation on a plane
Summary:
The idea behind getting the supported transformations is to tell KScreen
which transformations are actually supported and thus not even allow the
user select a setting which is not supported.

59f7ed9c78 [platforms/drm] Forward the mode changes to the OutputInterface
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.

Test Plan: Run kinfocenter to verify the current mode is properly set.

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.

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.

fc887ab907 Render GL Window decorations at the correct scale
Summary:
Under wayland we support high DPI putting by putting a separation
between the logical co-ordinate system and the resolution of rendered
assets.

When a window is on a high DPI screen, we should render at the higher
resolution.

Like the window scaling this handles any combination of a 2x scaled
decoration being rendered on a 1x screen or vice versa.

---
This patch is a bit different from the other scaling stuff. We have to
generate the quads *before* we have an updated texture with the new
scale. This means the scale isn't attached to the buffer like elsewhere.

That's why I added a property in TopLevel so there's still one canonical
source and things can't get out of sync.

BUG: 384765

Test Plan:
Crystal clear breeze and oxygen decos on my @2x display
Drag windows to attached @1x display, things still look OK when across 2
screens
Changing the scale of a screen updated the decos instantly

54b36325f7 Support software QtQuickRendering in Aurorae
Summary:
For software QtQuick rendering we want to create a pixmap buffer and
render our contents in there.

m_rendercontrol->grab does this, but also covers the GL side in pretty
much the same way that we were currently doing.

In doing so I found a bug in Qt, that's submitted upstream, and also worked round.

Test Plan:
Tested with forced software mode, could see an Aurorae decorations
Tested without (so normal code), could see an Aurorae decorations
Tested wayland on nvidia with software rendering, didn't freeze

Whether we then end up using GL, painter or xrender rendering is irrelevant
(but I tested two of them anyway)

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.

7e6721ece0 Scaled decorations in QPainter mode
Summary:
Under wayland we support high DPI putting by putting a separation
between the logical co-ordinate system and the resolution of rendered
assets.

I didn't include window decorations in the previous wayland scaling
patchset. They were drawn them at a standard resolution, which is
implicitly scaled up.

This uses the Qt scaling, meaning oxygen and breeze (and others) get
perfect high DPI support with zero client changes.

Like the window scaling this handles any combination of a 2x scaled
decoration being rendered on a 1x screen or vice versa.

5d7e22e5dc Fix viewport on vertically stacked monitors
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.

BUG: 386099
BUG: 385655

Test Plan:
Had two monitors
Side by side was - fine
Stacked vertically - still fine

Modded X code to extend in y instead of x.
3 monitors worked fine.

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.

gdb breakpoint that the sync still works

abedb464d5 [QPA] Implement Screen on top of internal Screens API
Summary:
The test DontCrashUseractionsMenu (Waylandonly) found an issue in our
screen handling implementation in the QPA. The code exposed a short time
frame between the dummy screen getting destroyed and the first screen
being added. This could result in a crash of KWin.

There is actually no need to implement Screen on top of Wayland screen.
KWin has all the knowledge, so we can also base this on top of the
Screens API.

Advantages:
 * no delays due to Wayland roundtrips
 * handle screen getting removed (was a TODO)
 * handle resolution changes (was a TODO)

The new implementation has a disadvantage that it destroys and readds
all screens whenever something around the screen changes. This shouldn't
be an issue in practice as it's only for the internal QPA and thus only
affects KWin internal windows which is placed in global coordinates
anyway. If it turns out to be a problem we need to track better the
screen changes - so far those were not tracked at all.

Test Plan: Run a few unit tests which change screens

09489a4c2b Add a pure virtual method to Platform to describe the supported compositors
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.

This is just a garbage value and it crashes in Mesa when we do our first

I've replaced that with an explicit method then we can use shared_ptr's

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.
