* Add a tech preview eglfs device integration for VSP2 compositionJohan Klokkhammer Helsing2018-01-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This creates a new device integration for eglfs, eglfs_kms_vsp2, that's very similar to eglfs_kms_gbm, but includes an extra step for doing VSP2 hardware compositing. The main Qt content is drawn to double buffered off-screen GBM buffers which are converted using drmPrimeHandleToFD so we get DMA buffer file descriptors that can be used by the VSP2 blending hardware. The blending hardware writes to double buffered DRM dumb buffers, which are flipped with drmModePageFlip. Communicating with the VSP2 is done using the Video4Linux2 (V4L2) streaming API. There are two steps in creating abstractions for this. First, there is the QLinuxMedia class that consists of a Qt style wrapper for V4L2 without anything VSP2 specific. Second, there is QVsp2BlendingDevice which hides some of the streaming details of the VSP2 and has some level of error recovery. Both classes include a fair bit of logging and error reporting. The patch is written with Wayland compositors in mind, but should work for other use cases as well. This is just the basic support to make compositing work, additional features may be added in subsequent patches, i.e: - Auto-detect VSP2 (-feature-vsp2 currently needs to be explicitly enabled). - Support for setting the alpha value of a layer. - Support clipping layers. - Support for scaling layers. - Support for other output formats than RGBA32. - Hardware cursor support. - Support foreign layers below the main Qt layer. - Support for memory mapped and user pointer buffer types (currently only DMA buffers are supported).

* Separate KMS and GBM testsLaszlo Agocs2015-10-141-1/+1
| | | | | | | | | | | | | | | | KMS is no longer a platform plugin so the relevant leftover bits are now removed. As the introduction of the EGLDevice-based backend for eglfs shows, using DRM/KMS is not tied to GBM, separate buffer management approaches, like EGLStreams, work fine as well. Therefore separate KMS from GBM and remove the EGL and GLES dependency in the tests - this way there is nothing preventing us from using GBM without GL for example.

* eglfs: Pluginize RPi, iMX6 and Mali backendsLaszlo Agocs2015-03-051-0/+3
| | | | | | | | | | | | | | eglfs does not depend on the device makespecs anymore when it comes to these device integration backends (hooks). Instead, backends are autodetected by configure. The name of the preferred plugin is still set in the device makespecs. This is optional. When not set and there is more than one plugin present in the system, the environment variable QT_QPA_EGLFS_INTEGRATION will have to be set at runtime. In the absence of that, the order is undefined.

* Pluginize the eglfs hooksLaszlo Agocs2014-12-081-0/+4
Following the principle of device integrations in QtWayland and soon xcb, a plugin interface is being introduced to gradually replace the statically compiled-in hooks. The interface is same as before for the time being, for compatibility with the existing device-specific hooks. QEglFSHooks is now just a dummy subclass for QEGLDeviceIntegration to support the legacy, compiled-in, device-specific hooks. When -device is not used with configure and so there is no hook active, the new plugin-based approach kicks in. The environment variable QT_QPA_EGLFS_INTEGRATION can be set to indicate the preferred integration name (e.g. eglfs_x11, eglfs_kms). It can also be set to "none", indicating that no plugins should be considered and the default, non-specialized integration is to be used. (this is for devices, like Beagleboard|bone, that do not need any special code to set up EGL) Device makespecs can set EGLFS_DEVICE_INTEGRATION. The value is then used as the default, preferred plugin name when QT_QPA_EGLFS_INTEGRATION is not set. In the future device makespecs are expected to set a plugin name instead of relying on the traditional EGLFS_PLATFORM_HOOKS_*. When neither the QT_QPA_EGLFS_INTEGRATION nor EGLFS_DEVICE_INTEGRATION are set, all plugins will be tried in an unspecified order. The first one that succeeds to load is used. If all fails or there are no plugins, the built-in, non-specialized integration is used. To debug what integration is being used, enable the logging category qt.qpa.egldeviceintegration. There is some built-in logic for desktop/Mesa based systems: Under X, eglfs_x11 is preferred, otherwise eglfs_kms is prioritized. This, assuming sufficient permissions to video and input devices, allows simply launching apps with -platform eglfs. No more editing of eglfs.pri.
