Throughput test method

Set the CPU to work at the highest frequency

• Set to userspace mode : echo userspace > /sys/devices/system/cpu/cpufreq/policy0/scaling_governor
• Check mode set succeed : cat /sys/devices/system/cpu/cpufreq/policy0/scaling_governor
• List all available frequencies : cat /sys/devices/system/cpu/cpufreq/policy0/scaling_available_frequencies
• Set highest frequency : echo 408000 > /sys/devices/system/cpu/cpufreq/policy0/scaling_setspeed
• Check frequency : cat /sys/devices/system/cpu/cpufreq/policy0/cpuinfo_cur_freq

Set the CPU to work at the highest frequency(Some platforms cannot be set).

• Set to userspace mode : echo userspace > /sys/class/devfreq/dmc/governor
• Check mode set succeed : cat /sys/class/devfreq/dmc/governor
• List all available frequencies : cat /sys/class/devfreq/dmc/available_frequencies
• Set highest frequency : echo 528000000 > /sys/class/devfreq/dmc/userspace/set_freq
• Check frequency : cat /sys/class/devfreq/dmc/cur_freq

Run librkcrypto_test -t to perform the throughput test.

Test principle: Perform encryption or decryption operations on 1M Byte data continuously and calculate the amount of data processed in 1 second.
