# test cases.
# 1) Run tbench benchmark on specific governors, ondemand or schedutil.
# 2) Run tbench benchmark comparative test on acpi-cpufreq kernel driver.
# 3) Get desire performance, frequency, load by perf.
# 4) Get power consumption and throughput by amd_pstate_trace.py.
# 5) Analyse test results and save it in file selftest.tbench.csv.
# 6) Plot png images about performance, energy and performance per watt for each test.
