glmark2

代码说明：

说明：  glmark2 测试对象是NVIDIA drive板子。 发现这个跑分软件对于强大的NVIDIA板子而言，没有占用太多资源。(Glmark2 is a popular open source GPU benchmarking tool with OpenGL2 2.0 and OpenGLES 2.0 support, available for Linux and Android platform. It is developed with a goal of easy and effective GPU benchmarking for ARM hardware in embedded systems by the Linaro team. Glmark2 binary packages are available in official Ubuntu repository, but not available in Debian repository, so we have to compile and install latest glmark2 form its git repository.)
