Using this plugin, applications may use +QGLWidget & QGLPixelBuffer with OpenGL ES. The integration with PowerVR drivers +is built as two libraries: The actual QScreen plugin used by Qt (in the +pvreglscreen directory) and a WSEGL plugin for the PowerVR drivers (in the +QWSWSEGL directory). + +The PowerVR drivers provide the WSEGL plugin API to allow window systems such as +QWS to integrate correctly. In order to use the integration, the WSEGL plugin +(libpvrQWSWSEGL.so, usually installed into the Qt library directory) must be in +the LD library path. The PowerVR driver also needs to be told which WSEGL library +to use. This is done by creating/modifying /etc/powervr.ini: + +[default] +WindowSystem=libpvrQWSWSEGL.so + +Note: It is important that the /etc/powervr.ini file not contain ^M (Ctrl-M) DOS +end of line markers at the end of its lines. If ^M markers are present, then the +libpvrQWSWSEGL.so driver will not be loaded and the default null Linux driver +will be loaded silently instead. Make sure that the end of line markers are +strictly Unix-style markers. + + +*************************************************************************** +* IMPORTANT: To build the QScreen plugin and the WSEGL library it depends * +* on, the pvr2d.h, wsegl.h headers for your platform are required. These * +* can be obtained either through your platform provider or directly from * +* Imagination Technologies. * +*************************************************************************** + + +When you start a Qt/Embedded application, you should modify the QWS_DISPLAY +environment variable to use the "powervr" driver instead of "LinuxFb". For +example, if your original QWS_DISPLAY variable was: + + LinuxFb:mmWidth40:mmHeight54:0 + +then it should be changed to: + + powervr:mmWidth40:mmHeight54:0 + +To test the OpenGL ES integration, you can use the hellogl_es example and run it +on the device with: + + hellogl_es -qws + + +Know Issues: + * A QGLWidget may not have window decorations if it is a top-level window. + * On some platforms, starting a QWS application after the system has been up + for a long time may cause the driver to fail. This is due to fragmentation + of main memory prevening older PowerVR drivers from allocating a contiguous + region of phyical RAM for the GL surface. diff --git a/src/plugins/gfxdrivers/powervr/powervr.pro b/src/plugins/gfxdrivers/powervr/powervr.pro new file mode 100644 index 0000000000..f31ad042d8 --- /dev/null +++ b/src/plugins/gfxdrivers/powervr/powervr.pro @@ -0,0 +1,3 @@ +TEMPLATE = subdirs +SUBDIRS = QWSWSEGL pvreglscreen +CONFIG += ordered diff --git a/src/plugins/gfxdrivers/powervr/pvreglscreen/pvreglscreen.cpp b/src/plugins/gfxdrivers/powervr/pvreglscreen/pvreglscreen.cpp new file mode 100644 index 0000000000..3a94851bb4 --- /dev/null +++ b/src/plugins/gfxdrivers/powervr/pvreglscreen/pvreglscreen.cpp @@ -0,0 +1,390 @@ +/**************************************************************************** +** +** Copyright (C) 2009 Nokia Corporation and/or its subsidiary(-ies). +** Contact: Qt Software Information (qt-info@nokia.com) +** +** This file is part of the plugins of the Qt Toolkit. +** +** $QT_BEGIN_LICENSE:LGPL$ +** No Commercial Usage +** This file contains pre-release code and may not be distributed. +** You may use this file in accordance with the terms and conditions +** contained in the either Technology Preview License Agreement or the +** Beta Release License Agreement. +** +** GNU Lesser General Public License Usage +** Alternatively, this file may be used under the terms of the GNU Lesser +** General Public License version 2.1 as published by the Free Software +** Foundation and appearing in the file LICENSE.LGPL included in the +** packaging of this file.
