* eglfs_kms: Add headless mode for DRM render nodesLaszlo Agocs2017-09-051-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Attempting to switch /dev/dri/cardX to /dev/dri/renderDY is futile on its own now since many output-related drm operations fail and we eventually crash. Add a new headless mode that skips the real screen stuff and registers a fairly dummy, headless screen, does not bother with the mouse cursor, and disallows rendering to the screen via a QWindow (while keeping the actual rendering still fully functional). Such applications will not need any special privileges and will run even if there is a DRM master (X11, Wayland compositor) active. For example the configuration can look like this: { "device": "/dev/dri/renderD128", "headless": "1024x768" } After this applications have two choices to perform offscreen rendering: 1. Use an ordinary window (and its default framebuffer, meaning the gbm_surface), e.g. a QOpenGLWindow subclass MyOpenGLWindow w; w.show(); // will not actually show on screen w.grabFramebuffer().save("output.png"); Note that there is no vsync-based throttling. Also note that windows are still sized to match the screen size, hence the need for specifying a size in the headless property. 2. Or the typical offscreen approach with an extra FBO QOffscreenSurface s; s.setFormat(ctx.format()); s.create(); ctx.makeCurrent(&s0; QOpenGLFramebufferObject fbo(1024, 768); fbo.bind(); ctx.functions()->glClearColor(1, 0, 0, 1); ctx.functions()->glClear(GL_COLOR_BUFFER_BIT); fbo.toImage().save("output.png"); ctx.doneCurrent(); Task-number: QTBUG-62262 Change-Id: Ic1dbfa2b27b223bd5ef8ba36b665f0f61abf4f06 Reviewed-by: Qt CI Bot <qt_ci_bot@qt-project.org> Reviewed-by: Andy Nichols <andy.nichols@qt.io>
* eglfs_kms: Output cloning supportLaszlo Agocs2017-09-051-0/+11
| | | | | | | | | | | | | | | | | | | | | { "device": "/dev/dri/card0", "outputs": [ { "name": "HDMI1", "mode": "1920x1080" }, { "name": "DP1", "mode": "1920x1080", "clones": "HDMI1" } ] } Here, assuming the QScreen for DP1 is unused and the resolution is the same, DP1 will simply mirror whatever is on HDMI1. The plane-based mouse cursor is not currently supported. Same goes for any form of scaling since this simply scans out the same framebuffer on all target CRTCs.

* Use correct DRM event context versionJonathan Liu2017-07-261-1/+1
| | | | | | | | | | | | | | Explicitly declare which DRM event context version we want to use, rather than just the latest one libdrm supports. New versions may change semantics, or extend the structure, in ways we're unaware of. Stick with version 2, which is the version that introduced page_flip_handler.

* eglfs: Move remaining sources to under apiLaszlo Agocs2016-09-221-1/+1
| | | | | | | | | | | | | | Move platform integration, context and offscreensurface to under 'api'. This allows accessing these from out-of-tree eglfs backends as well. For instance, the upcoming eglfs_emu backend for the Qt Simulator may need access to QEglFSIntegration. Clean up the project files and remove out-of-date comments (the private module QtEglFSDeviceIntegration is not really header-less since 5.7).

* eglfs: Configurable screen order in the virtual desktopLaszlo Agocs2016-08-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Say one wants a virtual desktop with the display on HDMI above the display on DisplayPort: { "device": "drm-nvdc", "virtualDesktopOrientation": "vertical", "outputs": [ { "name": "HDMI1", "virtualIndex": 0 }, { "name": "DP1" } ] } Undefined virtualIndex values map to INT_MAX and will go after the explicitly specified ones. However, the sorting is stable so the original order from the DRM connector list is preserved between such outputs.

* Multi-screen handling for the eglfs_kms_egldevice backendDominik Holland2016-04-151-0/+158
Separates the generic kms classes into a own kms static lib called QtEglFsKmsSupport. The eglfs_kms plugin was changed to use these base classes and got renamed accordingly to QEglFSKmsGbm*. The eglfs_kms_egldevice plugin got extended to also derive from the kms base classed and by this provides multi-screen support Change-Id: I6de6a754e94cb8d52cf8e658b03c6bd6637674a1 Reviewed-by: Laszlo Agocs <laszlo.agocs@theqtcompany.com>
