The default SD card image included in Processor SDK already has GPU support enabled. In order to test the GPU, the following tests could be launched:
Kmscube
# /etc/init.d/weston stop
# kmscube --device=/dev/dri/card0
Glmark2
The test could be launched with and without weston.
# /etc/init.d/weston restart
# glmark2-es2-wayland --fullscreen
# /etc/init.d/weston stop
# glmark2-es2-drm
Qt
The Qt framework is enabled in the default SD card image. Qt applications could be launched with Weston or EGLFS. The below commands could be used to launch Qt tests:
# cd /usr/share/qt5/examples/gui/analogclock
# /etc/init.d/weston restart
# ./analogclock
# /etc/init.d/weston stop
# ./analogclock --platform eglfs
