安装准备：
安装前请务必先更新Debian10到最新版本，参考：
http://t.rock-chips.com/forum.php?mod=viewthread&tid=1319&extra=page%3D1
安装步骤：
1. 安装Toybrick GBM mali组件
- sudo apt install toybrick-gbm-dev libgbm-dev
2. 安装OpenGL测试工具glmark2
3. 安装OpenCL和clinfo
- sudo apt install ocl-icd-opencl-dev ocl-icd-dev clinfo
4. 链接mali库
- sudo toybrick-mali.sh link
5. 如果有任何GL/CL库的操作，记得操作之前先unlink mali库
- sudo toybrick-mali.sh unlink
测试验证：
1. OpenGL性能测试
可以看到画面出现OpenGL 3D图像测试程序正在运行。完整运行指标如下：
