* Pluginize the eglfs hooksLaszlo Agocs2014-12-081-233/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Allow using a different framebuffer deviceLaszlo Agocs2014-01-161-4/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now /dev/fb0 is hardcoded. This is not ideal. Therefore QT_QPA_EGLFS_FB is introduced. This environment variable can be set to a different framebuffer device. Once it is set, eglfs will use the specific device. This is similar to linuxfb's fb=... plugin parameter. The actual behavior depends on the board-specific implementations. For now only iMX6 has real support. It extracts the index from the device name as bind the EGL display to the corresponding framebuffer using the vendor-specific fbGetDisplayByIndex(). Other hooks can follow suit later on. With this patch eglfs is at least on par with linuxfb, meaning that, if the board supports it, different apps can run on different screens.

* | eglfs: Move reusable functionality to eglconvenienceLaszlo Agocs2014-01-171-122/+7
|/ | | | | | | | | | | | | | | | | | | | | | | | 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.

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

There are two problems with the current design: 1. if (hooks) hooks->foo() doesn't work in debug mode when no platform hook is defined. The problem doesn't arise in release mode because the compiler optimizes away the if (hooks) into a no-op since hooks is NULL when no platform hook is defined. 2. Adding a new hook requires changing every platform's hook implementation. New approach: 1. Define QEglFSHooks as a class with virtual functions. A stub file provides the default implementation. 2. Platform hooks derive from above class and reimplement whatever is needed. The filenames and variables have been changed to be more in line with the Qt style.
