Read Me

Tool for performance testing similar to powertop.
cpu-usage shows overview about cpu activities using kernel values from:

/proc/stat
 - time spent in different kernel modes in jiffies units (typically 10ms)

/sys/devices/system/cpu/cpu0/cpufreq/stats
 - time spent in available cpu frequencies in jiffies units

/sys/devices/system/cpu/cpu0/cpuidle
 - time spent in available CPU power idle states in us
   C0 is the most active state

Tested on Intel and ARM cpu.
