6c9026628c Fix DrmOutput sometimes being freed with a pending pageflip, often when waking from sleep.
It is possible for updateOutputs to be called when a pageflip is pending.
Freeing a DrmOutput with a pending pageflip is not allowed (see ~DrmOutput assert - the page flip handler will be called on the freed memory, possibly leading to use-after-free).
This works around the problem by delaying the destruction with teardown().

0ef5ddfd47 [drm] Do not blank crtc in atomic mode
In atomic setting mode, when external display tears down, it will blank
crtc with dump buffer by legacy api, then re-plug the external display,
the blank can not be removed. We think the blank is not needed in atomic
mode setting.

cb7a9456c0 [wayland] Rework Xcursor theme loading code
Currently in order to load an Xcursor theme, kwin uses libwayland api,
which looks really awkward because of the way how the compositor talks
to itself via the internal connection.

The main motivation behind this change is to limit the usage of kwayland
client api in kwin.

a13ecf8d0e [wayland] Add new XdgOutput properties
Summary:
AbstractOutput::name() behaviour is changed so that it matches the X11
behaviour, showing an identifier like "HDMI-0".

XdgOutput.name is set to this name.

XdgOutput.description is currently set to the manufacturer name and
model, but it's not exposed to Qt so we probably don't care too much.

This should fix plasmashell changing applets when switching between X11
and wayland.

Test Plan:

Summary:
As is KWin only had 1 Cursor which was a singleton. This made it impossible for
us to properly implement the tablet (as in drawing tablets) support and show where

This patch makes it possible to have different Cursors in KWin, it makes all the
current code still follow the mouse but the tablet can still render a cursor.

be759b7d33 Use AbstractClient instead of XdgShellClient wherever possible
Summary:
Currently, we have only one shell client type - XdgShellClient. We use
it when we are dealing with Wayland clients. But it isn't really a good
idea because we may need to support shell surfaces other than xdg-shell
ones, for example input panel surfaces.

In order to make kwin more extensible, this change replaces all usages
of the XdgShellClient class with the AbstractClient class.

Test Plan: Existing tests pass.

For that rendering the current view into a separate framebuffer bound to a

This allows us to leave the Effects system and internal model-view-projection
matrix untouched. The rotation in the post-processing step is isolated.

9b3d9e58a4 ScreenEdge: Do not use localtime for measuring duration
Summary:
QDateTime::fromMSecSinceEpoch uses Qt::LocalTime by default. This involves an
expensive localtime conversion. So instead force things to use UTC, as there
is no need for timezone information when tracking durations.

This is especially noticeable on Bedrock Linux, which uses a Fuse mounted
/etc, which is slower than a plain /etc and causes quite some slowdown there.
See https://github.com/bedrocklinux/bedrocklinux-userland/issues/140 for
details.

Test Plan: The screenedge unit test still passes.

1e3128b0db Flexible composite swap and timer events
Summary:
The GLX backend might need a combination of swap and composite timer events for
continous painting.

The reason for that is that if the buffer age extension is not available we
fall back to copies in case not the whole screen is repainted.

The timer logic is adapted to make this possible in a lean way what cleans up
the Compositor class in several ways.

Test Plan: Tested on X11 (with/without swap events, buffer age enabled)  and Wayland.

Once found we create the Property object and there should be not another one
with the same name afterwards. In any case we would leak memory. Therefore just
directly return once the property was found.

This gives us the added benefit that we can put out a warning in case the

84d75cb567 [x11] Add support for _GTK_FRAME_EXTENTS
Summary:
KDE is known for having a strong view on the client-side decorations vs
server-side decorations issue. The main argument raised against CSD is
that desktop will look less consistent when clients start drawing window
decorations by themselves, which is somewhat true. It all ties to how
well each toolkit is integrated with the desktop environment.

KDE doesn't control the desktop market on Linux. Another big "player"
is GNOME. Both KDE and GNOME have very polarized views on in which
direction desktop should move forward. The KDE community is pushing more
toward server-side decorations while the GNOME community is pushing
more toward client-side decorations. Both communities have developed
great applications and it's not rare to see a GNOME application being
used in KDE Plasma. The only problem is that these different views are
not left behind the curtain and our users pay the price. Resizing GTK
clients in Plasma became practically impossible due to resize borders
having small hit area.

When a client draws its window decoration, it's more likely that it also
draws the drop-shadow around the decoration. The compositor must know
the extents of the shadow so things like snapping and so on work as
expected. And here lies the problem... While the xdg-shell protocol has
a way to specify such things, the NetWM spec doesn't have anything like
that. There's _GTK_FRAME_EXTENTS in the wild, however the problem with
it is that it's a proprietary atom, which is specific only to GTK apps.

Due to that, _GTK_FRAME_EXTENTS wasn't implemented because implementing
anything like that would require major changes in how we think about
geometry.

Recent xdg-shell window geometry patches adjusted geometry abstractions
in kwin to such a degree that it's very easy to add support for client
side decorated clients on X11. We just have to make sure that the
X11Client class provides correct buffer geometry and frame geometry when
the gtk frame extents are set.

Even though the X11 code is feature frozen, I still think it's worth
to have _GTK_FRAME_EXTENTS support in kwin because it will fix the resize
issues. Also, because KWin/Wayland is unfortunately far from becoming
default, it will help us with testing some implementation bits of the
window geometry from xdg-shell.

BUG: 390550
FIXED-IN: 5.18.0

Test Plan:
Things like quick tiling, maximizing, tiling scripts and so on work as
expected with GTK clients.

8d13729031 [platforms/x11] Never block on retrace, always present after paint
Summary:
Compositing in X11 was done time shifted, meaning that we paint first, then
wait one vblank interval length and present on prepareRenderingFrame the
previous paint result. This is supposed to make sure we don't miss the vblank
and in case of block till retrace be able to continue issuing commands and
only shortly before next vblank present.

This is counter-intuitiv, not how we do it on Wayland or even on MESA with X.
The reason seems to be that the GLX backend was in the beginning written
against Nvidia proprietary driver which needed this but nowadays even this
driver defaults to non-blocking behavior on buffer swap.

Therefore remove this legacy anomaly fully and directly present after paint.
We then wait one refresh cycle and in the future can optimize this by delaying
the paint and present till shortly before vsync.

Test Plan: kwin_x11 tested on i915 and Nvidia proprietary driver.

Selecting not to vsync does not make sense for an X11 compositor. In the end
we want clients to be able to present async if they want to but the compositor
is supposed to send swaps with vsync to the XServer in order to not generate

There was also a detection logic which did some questionable things in case
vsync was not available. I don't think this is necessary at all since we can
just always run a timer to present with or without vsync.

ad892ce3a6 [platforms/x11] Remove triple buffering detection
Summary:
It is not clear what the advantage of triple buffering is for KWin. An X11
compositor is meant to swap buffers once every monitor cycle. For that triple
buffering is not necessary.

The functionality is not maintained, does not reliably work as displayed by
the existence of an environment variable to force some behavior, pollutes
our code and every compositing-related problem that might be mitigated with
triple buffering should find a simpler and more fitting solution with other
means.

There is one caveat which is if we shall block for retrace. We set it
currently according to the result of the swap profiler and in the most common
case with double buffering it is set to true. But on Nvidia systems this might
be actual the wrong behavior. Instead of trying to work around this ignore
the issue for now and move the overall architecture to something less complex
by presenting after paint how we do it in the Wayland DRM backend and with
double buffering on GLX (although this is at the moment also borken because
we actually present then twice).

Test Plan: kwin_x11 tested on i915.

40b0296d5c [libkwineffects] Introduce API to easily show a QtQuick scene in an effect
Summary:
EffectQuickView/Scene is a convenient class to render a QtQuick
scenegraph into an effect.

Current methods (such as present windows) involve creating an underlying
platform window which is expensive, causes a headache to filter out
again in the rest of the code, and only works as an overlay.

The new class exposes things more natively to an effect where we don't
mess with real windows, we can perform the painting anywhere in the view
and we don't have issues with hiding/closing.

QtQuick has both software and hardware accelerated modes, and kwin also
has 3 render backends. Every combination is supported.

* When used in OpenGL mode for both, we render into an FBO export the
texture ID then it's up to the effect to render that into a scene.

* When using software QtQuick rendering we blit into an image, upload
that into a KWinGLTexture which serves as an abstraction layer and
render that into the scene.

* When using GL for QtQuick and XRender/QPainter in kwin everything is
rendered into the internal FBO, blit and exported as an image.

* When using software rendering for both an image gets passed directly.

Mouse and keyboard events can be forwarded, only if the effect
intercepts them.

The class is meant to be generic enough that we can remove all the
QtQuick code from Aurorae.

The intention is also to replace EffectFrameImpl using this backend and
we can kill all of the EffectFrame code throughout the scenes.

The close button in present windows will also be ported to this,
simplifiying that code base.

Classes that handle the rendering and handling QML are intentionally
split so that in the future we can have a declarative effects API create
overlays from within the same context. Similar to how one can
instantiate windows from a typical QML scene.

Notes:
I don't like how I pass the kwin GL context from the backends into the
effect, but I need something that works with the library separation. It
also currently has wayland problem if I create a QOpenGLContext before
the QPA is set up with a scene - but I don't have anything better?

I know for the EffectFrame we need an API to push things through the
effects stack to handle blur/invert etc. Will deal with that when we
port the EffectFrame.

Test Plan: Used in an effect

ffcbe24e2b Rename Client to X11Client
Summary:
Currently each managed X11 client is represented with an instance of
Client class, however the name of that class is very generic and the
only reason why it's called that way is because historically kwin
was created as an x11 window manager, so "Client" was a sensible choice.

With introduction of wayland support, things had changed and therefore
Client needs to be renamed to X11Client in order to better reflect what
that class stands for.

Renaming of Client to X11Client was agreed upon during the last KWin
sprint.

62a7db7028 Use nullptr everywhere
Summary:
Because KWin is a very old project, we use three kinds of null pointer
literals: 0, NULL, and nullptr. Since C++11, it's recommended to use
nullptr keyword.

This change converts all usages of 0 and NULL literal to nullptr. Even
though it breaks git history, we need to do it in order to have consistent
code as well to ease code reviews (it's very tempting for some people to
add unrelated changes to their patches, e.g. converting NULL to nullptr).

Test Plan: Compiles.

6b610927f4 [platforms/drm] introduce env var to select GPU
Summary:
In some environemnts it is possible that udev detection of primary GPU
fails and it picks the first available card (normally card0). But it is
not desired, and it would be required to use different card (card1).

Introduce environment variable, which when used, will make it possible
to use different card node then one selected by udev.

You can use it like KWIN_DRM_DEVICE_NODE=/dev/dri/card1 kwin_wayland

Test Plan: Tested on the device where card0 was not usable for kms, but card1

df3c1de848 [platforms/drm] Rework enablement and dpms switching
Summary:
This patch further refines output management.

We go now through AbstractWaylandOutput virtual functions to enable and
disable outputs.

Dpms changes and enablement switches use separate code paths at start in the
Drm backend code since they are similar but not the directly same. Common code
is shared though, functions are renamed accordingly.

Asserts have been put in place to better understand and check the control
flow. A seemingly unnecessary call to DrmOutput::pageFlipped on reactivation
after Vt switch has been removed to allow for that.

In future patches we need to look additionally at the legacy mode switching
code path which was and is still not working and better handling of the
current monitor Dpms state. For example a monitor being switched off is not
properly acted on and the workspace still expanded.

Test Plan:
With one and two monitors:
* Dpms off/on
* Vt switches
* Screen disable/enable

Summary:
This lifts the enablement code for outputs from the DRM backend to Platform
allowing other Wayland backends in the future to use this interface as well.

To do that we also create some helper functions on Platform level and have to
spill some KWayland classes into AbstractOutput what motivates a further split
of Platform into a Wayland child class like for AbstractOutput.

Test Plan: Disabled and enabled an output in DRM session.

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.
