* Support adopting an existing EGLContext in eglfs and xcbLaszlo Agocs2014-05-091-4/+3
| | | | | | | | | | | Add also a manual test application. For GLX there is an autotest since that is likely to be run on one of the CIs. For EGL and especially eglfs this is likely not the case so a manual test is better.

* eglfs: Avoid double surfaceFormatFor() callsLaszlo Agocs2014-03-251-2/+2
| | | | | | | | | The hooks' surfaceFormatFor() function is called twice on the format when creating platform contexts, once from the integration and once from the constructor. This is potentially dangerous. Do it only once. Change-Id: I58eadce01b8f2183abe116f88b1ee9f2b47c003d Reviewed-by: Jørgen Lind <jorgen.lind@digia.com>

* 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.

* Add swapInterval to QSurfaceFormatLaszlo Agocs2013-11-131-18/+2
| | | | | | | | | | | | | | | Implement swap interval support for EGL, GLX and WGL. The environment variable QT_QPA_EGLFS_SWAPINTERVAL is renamed to QT_QPA_EGL_SWAPINTERVAL and can be used to override the applications' setting of the swap interval.

* 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.

| | | | | | | | | | | | Inherits QSurface and allows to use OpenGL from an arbitrary thread. Platform plugins can implement QPlatformOffscreenSurface, otherwise an invisible QWindow is used by QOffscreenSurface.

* | eglfs: Introduce way of filtering out unwanted EGL configs.Samuel Rødal2013-01-181-1/+2
|/ | | | | | | | | | | | Some times a platform might want to exclude certain configs, for example based on EGL_NATIVE_VISUAL_ID. This patch introduces a new QEglConfigChooser class which has a virtual filterConfig() function which can be re-implemented in a sub-class to give finer control of how configs are chosen.

* eglfs: Make QEglFSWindow respect the window formatGirish Ramakrishnan2012-06-141-4/+1
| | | | | | | | | | | | | | Prior to this change, eglfs code used to override the window format with it's own format. With this change, eglfs will respect the window format. This is useful when the application requires a surface with alpha (for example, so that the video layer below is visible) QEglFSHooks::surfaceFormatFor() allows the hook author to override the context and window surface format.
