* Pluginize the eglfs hooksLaszlo Agocs2014-12-081-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* eglfs: Move reusable functionality to eglconvenienceLaszlo Agocs2014-01-171-10/+5
| | | | | | | | | | | | | | | | | | | | | | | | The cursor implementation is generic GL(ES) code that should be shared by all the present and future egl-based embedded platform plugins. Follow the pattern of QEGLPlatformContext and move this class into eglconvenience as QEGLPlatformCursor. Similarly, the common bits from the context implementation context are moved back to EGLPlatformContext. eglconvenience has now base classes for integration, screen, window, etc. too. By using these, eglfs becomes much smaller and cleaner. This also paves the way for creating new, separate EGL-based platform plugins for Android, embedded Linux, etc. Also added some documentation to each of the base classes. devicediscovery is now fixed to be usable on any platform. The implementation in this case is naturally a dummy one. This finally allows using it from anywhere without myriads of ugly ifdefs.

* EGLFS: Replace the global static 'hooks' variable with a functionThiago Macieira2013-02-261-1/+1
| | | | | | | | | | | | | | Having a global static variable in a header is a poor choice to start with. All .cpp including that header must use that variable or the compiler will warn of an unused static. Second, for the case of platform hooks, it's possible that it is reading the value of a variable that isn't initialised yet.

* Add support for forced VSYNC using the EGLFS platform plugin.Milian Wolff2013-02-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | Before a buffer swap the new QEglFSHooks::waitForVSync method is called which looks at QT_QPA_EGLFS_FORCEVSYNC and - if that is set and non-null - calls ioctl with the FBIO_WAITFORVSYNC request on the framebuffer device. This is required on some embedded platforms where the driver does not support VSYNC yet the Kernel provides a generic implementation. I tested this using QML_RENDER_TIMING=1 which proofs that the frame rate for an example of mine drops from >125fps to a straight ~60fps with a few frames that take ~33ms (i.e. 30fps) as expected for VSYNC. To prevent excessive open/close calls on the frame buffer device per frame, the file descriptor is now cached. To keep the QEglFSHooks interface as clean as possible this is done via a global static in qeglfshooks_stub.cpp and initialized and freed in platformInit and platformDestroy.
