How to execute EGL2.0 samples by GPU not CPU on imx6dl?

Hi,

I got this nxp gpu sdk from here.

https://www.nxp.com/webapp/sps/download/license.jsp?colCode=FSL_GPU_SDK_2.3&appType=file1&location=null&DOWNLOAD_ID=null&lang_cd=en

I downloaded it and build 01_SimpleTriangle by Makefile.x11.

Then I executed it on our imx6dl board, I found that it use up to 80% CPU resource.

However, I found it can executed by GPU because CPU usage decrease to 4~10% after I test some method on board

But I cannot confirm how to do it and I cannot repeat this situation when I create new terminal on board.

How to executed this sample by GPU?

Thanks!
