Buildroot stress-ng Linux系统压力测试

/**********************************************************************
 *            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：
    . Stress-ng
        http://kernel.ubuntu.com/~cking/stress-ng/
    . stress-ng.pdf
        http://kernel.ubuntu.com/~cking/stress-ng/stress-ng.pdf
    . stress-ng
        https://wiki.ubuntu.com/Kernel/Reference/stress-ng

二、使用示例：
    [buildroot@root ~]#  stress-ng --cpu  --tz -t
    stress-ng: info:  [] dispatching hogs:  cpu
    stress-ng: info:  [] cache allocate: using built-in defaults as unable to determine cache details
    stress-ng: info:  [] cache allocate: default cache size: 2048K
    stress-ng: info:  [] successful run completed in .05s ( min, 0.05 secs)
    stress-ng: info:  [] cpu:
    stress-ng: info:  []     imx_thermal_zone   57.57 °C
    [buildroot@root ~]#  stress-ng --matrix  -t 1m
    stress-ng: info:  [] dispatching hogs:  matrix
    stress-ng: info:  [] cache allocate: using built-in defaults as unable to determine cache details
    stress-ng: info:  [] cache allocate: default cache size: 2048K
    stress-ng: info:  [] successful run completed in .00s ( min, 0.00 secs)
