目的: 計算 CPU utilization 於多核心的 ARM 系統
CPU info location:
1. /proc/cpuinfo
2. /proc/stat
3. /proc/loadavg
4. /proc/<pid>/stat
5. /proc/<pid>/task/<tid>/stat
CPU test factor:
1. CPU load
2. CPU temperature
3. Process CPU utilization
4. Thread CPU utilization
5. CPU frequency / scaling
6. CPU BogoMIPS
7. CPU benchmark
8. CPU stress / long run
9. CPU info
10. Workload on specific CPU
11. Power consumption
12. Process queue
13. Interrupt
14. IO
15. Context switch
