      Notify the driver about the parts of the screen that will be repainted.
      In some cases this can be benefitial. This is especially useful on lima
      and panfrost devices (e.g. pinephone, pinebook, pinebook pro).
      Test Plan:
      Tested on a pinebook pro with a late mesa version.
      Basically I implemented it, then it didn't work and I fixed it.
      Maybe next step we want to look into our damage algorithm.

      The main advantage of SPDX license identifiers over the traditional

      [wayland] Add support for cropped and scaled surfaces · de2c4cb4
      Vlad Zahorodnii authored
      The wp_viewporter compositor extension allows clients to crop and scale
      their surfaces. It can be especially useful for applications wishing to
      reduce their power consumption, e.g. video players, etc.
      Given that there is no any direct relationship between the surface size
      and the buffer size anymore, we have to use specialized helper methods
      for converting coordinates from the surface-local space to buffer pixel
      space and vice versa.

      Dmabuf recovery on EGL reset · 7459aabc
      Roman Gilg authored
      The EGL platform might go away at any time through reconfiguration or because
      of a graphic error. KWin then resets the graphics. The dmabuf implementation
      must respect that and recover from a graphics reset by recreating all EGL
      images for existing buffer.
      This assumes that we won't change our graphics API mid-session and that
      supported plane and modifier configuration stays constant.
      In practise we remember all current dmabufs in a single map and only remove
      them if the client did destroy the resource.

      Port QPA away from Wayland · bebe8120
      Vlad Zahorodnii authored
      So far wayland was used by internal clients to submit raster buffers
      and position themselves on the screen. While we didn't have issues with
      submitting raster buffers, there were some problems with positioning
      task switchers. Mostly, because we had effectively two paths that may
      alter geometry.
      A better approach to deal with internal clients is to let our QPA use
      kwin core api directly. This way we can eliminate unnecessary roundtrips
      as well make geometry handling much easier and comprehensible.
      The last missing piece is shadows. Both Plasma::Dialog and Breeze widget
      style use platform-specific APIs to set and unset shadows. We need to
      add shadows API to KWindowSystem. Even though some internal clients lack
      drop-shadows at the moment, I don't consider it to be a blocker. We can
      add shadows back later on.

      Move SceneOpenGL into a dedicated plugin · 8ae37c42
      Martin Flöser authored
      Unfortunately a rather large change which required more refactoring than
      initially expected. The main problem was that some parts needed to go
      into platformsupport so that the platform plugins can link them. Due to
      the rather monolithic nature of scene_opengl.h a few changes were
      * SceneOpenGL::Texture -> SceneOpenGLTexture
      * SceneOpenGL::TexturePrivate -> SceneOpenGLTexturePrivate
      * texture based code into dedicated files
      * SwapProfiler code into dedicated files
      * SwapProfiler only used in x11 variants
      * Safety checks for OpenGL scene moved into the new plugin
      * signal declared in SceneOpenGL moved to Scene, so that we don't need
      to include SceneOpenGL in composite

      Make AbstractEglBackend a QObject · 01ddbe7d
      Martin Flöser authored
      Several of the subclasses are already derived from QObject.
      The main reason is that the class should be moved out of KWin core in
      order to move the OpenGL scene into a plugin. As Compositor calls into
      the AbstractEglBackend to unbind the wayland display this creates a
      problem which is easily solved by turning the AbstractEglBackend into a
      QObject and connect to the signal emitted by the Compositor.

      Pass EGL information from AbstractEglBackend to Platform instead of query · 9381411b
      Martin Flöser authored
      So far the Platform performed a deep query into the AbstractEglBackend
      to get information such as EGLContext, EGLConfig, EGLSurface. This
      change adjusts this so that the AbstractEGLPlatform forwards it directly
      whenever it gets informed about one following the approach already used
      for EGLDisplay. This simplifies the code a lot and allows to remove the
      dependency on the actual scene backend from the Platform (in order to
      split out the SceneOpenGL into a plugin).
      Test Plan:
      Run nested kwin_wayland, triggered Outline which requires all
      those methods.

      Refactor the specification of OpenGL context attributes · 3f4995fb
      Martin Flöser authored
      The current way to specify the OpenGL context attributes does no longer
      scale as can be seen in D6344. There are too many different context
      attribute sets and with every addition we grow lots of copied code. The
      chances to introduce errors in that code which is difficult to debug are
      very high. As can be seen in the glx backend which defines major 1,
      minor 2, but it should be major 2, minor 1.
      This change reworks this code by creating a builder class which contains
      only an abstract definition of what needs to be in the attributes.
      E.g. the version, whether it's robust and so on.
      Now we can just have a list of possible attributes in a well described
          auto builder;
          builder.setVersion(3, 1);
      All possible builders are added to a list and operated on in a for loop
      which tries to creat a context. Once it succeeded it breaks the list.
      In addition a debug statement is added which prints out the set of
      options which went into the context.
      So far this is only done for EGL, GLX can follow once D6344 is merged.

      Move querying the egl extensions into the AbstractEglBackend · d1de6899
      Martin Flöser authored
      Instead of having the egl extensions in the global kwinglutils lib it
      becomes private to the AbstractEglBackend. Just like on glx the
      glxextensions are moved into the platform.
      The extensions are queried from initEglAPI, that is as early as possible
      after initializing the EGLDisplay. This ensures that any implementing
      subclass can access the extensions early enough.
      As a note: the EglOnXBackend had a potentially wrong sequence for
      initializing the buffer age extension. It is now moved to the correct
      place where the result is needed for the first time.
      From the global API eglExtensions are removed from hasGLExtension and
      the eglExtensions function is dropped. As by that initEGL did not do
      anything it is also dropped.

      Pass function ptr to resolve glFunctions to initGL · d7fa8276
      Martin Flöser authored
      KWin still resolves some OpenGL function pointers. For that it needs to
      use either eglGetProcAddress or glxGetProcAddress. With other words the
      method to resolve needs to know whether it is egl or glx and needs both
      a dependency to egl and glx. Especially the dependency to glx is ugly as
      that pulls in XLib into our library.
      The way so far was to pass an enum value to the initGL method to know
      whether it's EGL or GLX. With this change the enum value is removed and
      replaced by a function pointer to resolve the methods.
      This simplifies the resolve code and allows to completely remove the glx
      variant we still had in the library. Thus kwinglutils library is now glx
      and XLib free.
      Test Plan: nested KWin with OpenGL/EGL still works

      Remove the unredirect fullscreen windows functionality · 996ee34e
      Martin Flöser authored
      Rational: unredirect fullscreen windows is a weird beast. It's intended
      to make fullscreen windows "faster" by not compositing that screen. But
      that doesn't really work as KWin jumps out of that condition pretty
      quickly. E.g. whenever a tooltip window is shown. KWin itself has a
      better functionality by supporting to block compositing completely.
      The complete code was full of hacks around it to try to ensure that
      things don't break.
      Overall unredirect fullscreen has always been the odd one. We had it
      because a compositor needs to have it, but it never got truly integrated.
      E.g. effects don't interact with it properly so that some things randomly
      work, others don't. Will it trigger the screenedge, probably yes, but
      will it show the highlight: properly no.
      By removing the functionality we finally acknowledge that this mode is
      not maintained and has not been maintained for years and that we do not
      intend to support it better in future. Over the...

      Support restarting the OpenGL compositor on Wayland · 9d7ef58b
      Martin Flöser authored
      KWin needs to support restarting the OpenGL compositor in case of a
      graphics reset event.
      On Wayland the tricky part is that the applications should not notice
      this. Most importantly KWin cannot just destroy the EGLDisplay and create
      a new one. But this is how a restart works: the complete compositor gets
      torn down and recreated - including the EGLDisplay.
      This change moves ownership of the EGLDisplay to the Platform.
      The AbstractEglBackend subclasses query the Platform whether there is
      already an EGLDisplay. Only if there is no EGLDisplay the EGLDisplay is
      created and only if no EGLDisplay is registered with Wayland the bind
      is performed.
      Another change is regarding the destruction: the AbstractEglDisplay does
      no longer unbind the Wayland display and does no longer destroy the
      EGLDisplay. The EGLDisplay is destroyed by the Platform - so very late
      on application exit. The Wayland display is unbound when the Compositor
      Test Plan:
      Limited testing with the added auto-test. This one needs to
      be extended to fully verify that OpenGL applications continue to work.
      But this requires build.kde.org to support OpenGL on Wayland.

      Move the loadTexture for X11 pixmap functionality to the EglOnXBackend · 2b196bfa
      Martin Flöser authored
      To use eglCreateImageKhr for an X11 pixmap we need an EGLDisplay created
      for the same XDisplay as the X11 pixmap. This means if we created an
      EGLDisplay for a GBM device, we are not allowed to load a texture from
      the X11 pixmap and can result in a crash in the driver.
      Similar in the nested X11 setup the EGLDisplay is created for the
      rendering window, but the X11 pixmaps are from the Xwayland server KWin
      started. They don't belong to the same windowing system.
      This change addresses this problem by moving the loading of X11 pixmaps
      from AbstractEglTexture to EglTexture of the EglOnX11Backend. Thus for
      any usage on a non X11 platform we cannot hit the code path any more.
      In addition the nested X11 platform can indicate that it doesn't support
      it and thus also doesn't go through the code path.
      Test Plan: Tested standalone and nested X11 platform
