I can't get 3D acceleration working in the Qt examples using the latest graphics SDK (4.06.00.01) for QWS (i.e. not X.org). I have been _trying_ to follow the massively out of date instructions at http://processors.wiki.ti.com/index.php/Building_Qt_with_OpenGL_ES_accelerated_by_SGX to the best of my skill.
Here is what I do and what happens:
./configure -prefix <my installation target directory> -embedded arm -platform qws/linux-x86_64-g++
-xplatform qws/linux-TIarmv7-sgx-g++ -depths 16,24,32 -qt-freetype -no-mmx -no-3dnow -no-sse
-no-sse2 -no-sse3 -no-sse4.1 -no-sse4.2 -no-ssse3 -no-avx -no-cups -qt-mouse-pc -no-mouse-tslib
-qt-mouse-linuxinput -plugin-mouse-pc -little-endian -commercial -opengl es2 -openvg -qt-gfx-transformed
-qt-gfx-linuxfb -qt-gfx-multiscreen -plugin-gfx-powervr -D QT_NO_QWS_CURSOR -D QT_QWS_CLIENTBLIT
10. make -j 4
11. make install
12. On the target I run
/usr/local/share/ti/ti-media-controller-utils/load-hd-firmware.sh start
/etc/init.d/pvr-init
/etc/init.d/rc.pvr start
export LD_LIBRARY_PATH=/lib:/usr/lib:/usr/local/lib
export QT_QWS_FONTDIR=/lib/fonts
export QT_PLUGIN_PATH=/plugins
In case you wondered, here is what pvr-init does (it is a clone of 38xx-demo without the installation part):
RM_SGX_RSTCTRL=0x48180F04
CM_SGX_CLKSTCTRL=0x48180900
CM_SGX_SGX_CLKCTRL=0x48180920
devmem2 $RM_SGX_RSTCTRL w 0x0 # Bring SGX out of reset
devmem2 $CM_SGX_CLKSTCTRL w 0x2 # Enable the SGX clocks
devmem2 $CM_SGX_SGX_CLKCTRL w 0x2 # Bring SGX out of idle
# while((RD_MEM_32(CM_SGX_SGX_CLKCTRL)) != 0x00040002); //Wait for SGX to come out of idle
#sleep 2
devmem2 0x56000014 > /etc/init.d/sgxrevision.txt
13. Finally I run the application: with "/examples/opengl/hellogl_es2/hellogl_es2 -qws -display powervr". I had to relocate my libusc.so because of the changes I made to the qmake.conf.
# /examples/opengl/hellogl_es2/hellogl_es2 -qws -display powervr

I do _not_ want to use TI's pre-packaged "out of the box" binaries. I want to be able to build Qt myself and build the graphics drivers myself. This is necessary for the company strategy. I can run qt demos without acceleration as well as 3d-only demos with acceleration.
Please can someone help.
Thanks very much,
Ralph
