Create a plugin for each of the wayland backends Each of the backends becomes a plugin. This allows kwin_wayland to load the requested plugin and kwin itself doesn't need to link all the libraries needed. E.g. libdrm is no longer linked if running kwin_x11. Also this allows to create backends for the non-standard EGL platforms (examples could be raspberrypi or Android devices).

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: https://lwn.net/Articles/653071 And on Martin's blog: https://blog.martin-graesslin.com/blog/2015/08/layered-compositing/ I used as model previous work by Daniel Stone for Weston: https://git.collabora.com/cgit/user/daniels/weston.git Reviewed-by: mgraesslin Tags: #kwin Differential Revision: https://phabricator.kde.org/D2370

Split drm_backend.{h,cpp} into separate files Summary: This changes splits up the monster file containing different types used in the DRM backend into separate files per class: - drm_backend.{h,cpp} - drm_buffer.{h,cpp} - drm_inputeventfilter.{h,cpp} - drm_output.{h,cpp} - drm_pointer.h No actual code changes other than build fixes. Clean up headers in the split files.

[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 when the page flip happens the DrmSurfaceBuffer will try to destroy the gbm_bo and crash as the gbm_surface is no longer valid.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.

Move SceneOpenGL into a dedicated plugin Summary: 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 required: * 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 Test Plan: Nested OpenGL compositor works Reviewers: #kwin, #plasma Subscribers: plasma-devel, kwin Tags: #kwin Differential Revision: https://phabricator.kde.org/D7740
