1## Throughput test method 2 3### Set the CPU to work at the highest frequency 4 5- Set to userspace mode : `echo userspace > /sys/devices/system/cpu/cpufreq/policy0/scaling_governor` 6- Check mode set succeed : `cat /sys/devices/system/cpu/cpufreq/policy0/scaling_governor` 7- List all available frequencies : `cat /sys/devices/system/cpu/cpufreq/policy0/scaling_available_frequencies` 8- Set highest frequency : `echo 408000 > /sys/devices/system/cpu/cpufreq/policy0/scaling_setspeed` 9- Check frequency : `cat /sys/devices/system/cpu/cpufreq/policy0/cpuinfo_cur_freq` 10 11### Set the CPU to work at the highest frequency(Some platforms cannot be set). 12 13- Set to userspace mode : `echo userspace > /sys/class/devfreq/dmc/governor` 14- Check mode set succeed : `cat /sys/class/devfreq/dmc/governor` 15- List all available frequencies : `cat /sys/class/devfreq/dmc/available_frequencies` 16- Set highest frequency : `echo 528000000 > /sys/class/devfreq/dmc/userspace/set_freq` 17- Check frequency : `cat /sys/class/devfreq/dmc/cur_freq` 18 19### Run `librkcrypto_test -t` to perform the throughput test. 20 21### Test principle: Perform encryption or decryption operations on 1M Byte data continuously and calculate the amount of data processed in 1 second.
