How to know whether an OpenGL demo is accelerated by hardware or not ?

My board is based on imx6q and the bsp is built from yocto (kernel version 3.10.17).

When I run OpenGL demos from fsl-gpu-sdk/GLES20_X11, some of them (e.g. 07_EnvironmentMapping) will output the following message: [     1] libGAL: Performing a software resolve! 

In fact, when 07_EvnironmentMapping is running, the cpu usage is about 2%, and that of Xorg is lower than 3%.

Does this message mean that the demo is rendered by software ? Could anyone tell me how to judge whether an OpenGL application is accelerated by GPU ?


Thanks very much in advance.
