## 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.
