H A DREADME-BENCH1 This is cpufreq-bench, a microbenchmark for the cpufreq framework.
9 - Identify average reaction time of a governor to CPU load changes
10 - (Stress) Testing whether a cpufreq low level driver or governor works
14 processes with a higher prio than the governor's kernel thread
27 cpufreq-bench helps to test the condition of a given cpufreq governor.
28 For that purpose, it compares the performance governor to a configured
