* eglfs/kms: Add framebuffer scaling ability with KMS atomicLionel CHAZALLON2018-04-041-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | This commit will add the possibility to have a different sizes between framebuffer and videomode using DRM atomic, which is not possible with DRM legacy. The main goal of this change is to allow to get decent performance on embedded devices which can support high resolution display (ie UHD), and which don't have a GPU able to achieve decent framerate in such resolutions. This patch adds a "size" member to the output configuration in KMS configuration file. The GBM framebuffer will be created with that size and the GBM screen will report that size so that EGLFS can do everything normally. Scaling planes with different size than the video mode size is not something supported consistently with DRM legacy, so that feature will be only available when using the DRM atomic API. This was tested on Rock64 device, both with drm legacy and atomic.

* eglfs_kms: Add headless mode for DRM render nodesLaszlo Agocs2017-09-051-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Add support for formats other than XRGB8888Laszlo Agocs2017-09-051-3/+21
| | | | | | | | | | | | | | | | | | Switch to drmModeAddFB2 and add mappings for RGB565 and ARGB8888, and some BGR variants. The default is XRGB8888, like before. Others can be requested in the config file with "format": "rgb565" or "argb8888" etc. on a per-output basis. If the primary plane does not support the format, modesetting and flipping will fail.

* Change EDID parsing qCWarnings to qCDebugsLaszlo Agocs2017-08-031-2/+2
| | | | | | | | | | | Avoid polluting the output by default. Unfortunately there are various systems (modern Fedora with XWayland, VMWare) where parsing will fail for some not yet known reason. Showing warnings on each and every Qt application startup is not desirable, especially since not having the EDID data available is far from being critical.

| | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | Not clear why separateScreen was overridden to true. The GBM-based backend goes with the default of false, leading to setting up the screens as virtual siblings and reporting the correct virtual desktop geometry. The difference currently lies in the OpenGL mouse cursor, which, unlike the GBM hardware cursor, does not yet support virtual desktops. Its behavior is not affected of the flag however.
