# Testing and monitor the cpu desire performance, frequency, load,
# power consumption and throughput etc. when this script trigger
# gitsource test.
# 1) Download and tar gitsource codes.
# 2) Run gitsource benchmark on specific governors, ondemand or schedutil.
# 3) Run tbench benchmark comparative test on acpi-cpufreq kernel driver.
# 4) Get desire performance, frequency, load by perf.
# 5) Get power consumption and throughput by amd_pstate_trace.py.
# 6) Get run time by /usr/bin/time.
# 7) Analyse test results and save it in file selftest.gitsource.csv.
#8) Plot png images about time, energy and performance per watt for each test.
