Asynchronous Test

After installing the KAELz4 library, perform operations described in this section to test its asynchronous functions and performance using test scripts in /KAE/KAELz4/test/kzip.

1. Install KAELz4. For details, see Installation Using Source Code.
2. Test the functions of asynchronous interfaces of the KAELz4 library.

   1 2	cd KAE/KAELz4/test/kzip sh runFunc.sh

3. Enable the fast mode of the driver and set a specific valid compression window length to achieve the maximum performance.

   rmmod hisi_zip modprobe hisi_zip perf_mode=1 uacce_mode=2 pf_q_num=256 export KAE_LZ4_WINTYPE=8 export KAE_LZ4_COMP_TYPE=8

4. Test the performance of asynchronous interfaces of the KAELz4 library.
