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). - -Qt/Embedded needs to be configured with the QT_QWS_CLIENTBLIT and -QT_NO_QWS_CURSOR defines. - -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. You * -* can find a copy of these headers in src/3rdparty/powervr for SGX based * -* platforms like the TI OMAP3xxx. They probably will not work on MBX * -* because of differences in the layout of certain PVR2D structures. * -* You can tell Qt where to find the actual headers for your system by * -* setting QMAKE_INCDIR_POWERVR in the mkspec. * -*************************************************************************** - -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 - -The driver also supports screen rotation if Qt is configured with the --qt-gfx-transformed option and the QWS_DISPLAY variable is wrapped in a -"Transformed" declaration: - - Transformed:powervr:mmWidth40:mmHeight54:Rot90:0 - -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.pri b/src/plugins/gfxdrivers/powervr/powervr.pri deleted file mode 100644 index 9df8c0ed5b..0000000000 --- a/src/plugins/gfxdrivers/powervr/powervr.pri +++ /dev/null @@ -1,2 +0,0 @@ - -INCLUDEPATH += $$QMAKE_INCDIR_POWERVR diff --git a/src/plugins/gfxdrivers/powervr/powervr.pro b/src/plugins/gfxdrivers/powervr/powervr.pro deleted file mode 100644 index f31ad042d8..0000000000 --- a/src/plugins/gfxdrivers/powervr/powervr.pro +++ /dev/null @@ -1,3 +0,0 @@ -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 deleted file mode 100644 index c981e0d300..0000000000 --- a/src/plugins/gfxdrivers/powervr/pvreglscreen/pvreglscreen.cpp +++ /dev/null @@ -1,351 +0,0 @@ -/**************************************************************************** -** -** Copyright (C) 2011 Nokia Corporation and/or its subsidiary(-ies). -** All rights reserved. -** Contact: Nokia Corporation (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 Technology Preview License Agreement accompanying -** this package. -** -** 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.
