 *            Buildroot stress-ng Linux系统压力测试
 * 说明：
 *     之前有使用lmbench对整板进行一些测试，如果相对某一部分专门进行测试，
 * 就可以参考使用stree-ng来进行处理。

一、参考文档：
    1. Stress-ng
        http://kernel.ubuntu.com/~cking/stress-ng/
    2. stress-ng.pdf
        http://kernel.ubuntu.com/~cking/stress-ng/stress-ng.pdf
    3. stress-ng
        https://wiki.ubuntu.com/Kernel/Reference/stress-ng

二、使用示例：
    [buildroot@root ~]#  stress-ng --cpu 0 --tz -t 60
    stress-ng: info:  [9331] dispatching hogs: 2 cpu
    stress-ng: info:  [9331] cache allocate: using built-in defaults as unable to determine cache details
    stress-ng: info:  [9331] cache allocate: default cache size: 2048K
    stress-ng: info:  [9331] successful run completed in 60.05s (1 min, 0.05 secs)
    stress-ng: info:  [9331] cpu:
    stress-ng: info:  [9331]     imx_thermal_zone   57.57 °C
    [buildroot@root ~]#  stress-ng --matrix 1 -t 1m
    stress-ng: info:  [9490] dispatching hogs: 1 matrix
    stress-ng: info:  [9490] cache allocate: using built-in defaults as unable to determine cache details
    stress-ng: info:  [9490] cache allocate: default cache size: 2048K
    stress-ng: info:  [9490] successful run completed in 60.00s (1 min, 0.00 secs)
