glmark2

glmark2 是基于 OpenGL 2.0 以及 ES 2.0 的一个性能测试.

此处我们只使用 glmark2-es2 ，软件包已经预装在RevyOS中，用于 x11-glesv2 的测试.

th1520 只支持 glmark-es2.

准备步骤

开始之前我们需要调整芯片进入高性能模式，在终端中执行下述命令即可，需要使用 sudo 或者root账户.

echo performance >  /sys/devices/system/cpu/cpufreq/policy0/scaling_governor 

cat /sys/devices/system/cpu/cpufreq/policy0/cpuinfo_cur_freq

如果在执行之后看到 "1848000" 数字，则表明已经调整至性能模式，可以继续向下操作.

开始运行

使用任意账户登陆系统，打开终端输入 glmark2-es2，需要将HDMI连接到显示器，请勿通过SSH连接执行.

输入命令后，桌面上会出现一个有图形活动的新窗口。

测试完成后，额外窗口会消失，分数会以 glmark2 Score: xxx 的形式输出在终端中。

测试示例:
