Email exchange with Yekai and I am told hisi_sec2 only support 2 threads in default. We can enable more threads when modprobe. I will try to find out the best way to enable more threads as default.

Disabling hisi_sec2 makes kernel to run crypto functions without accelerator. [Fix] Disable CONFIG_CRYPTO_DEV_HISI_SEC2 temporarily until we have proper driver. [Test] $ sudo stress-ng --aggressive --verify --timeout 330 --metrics-brief --tz --times --af-alg 0 $ echo $? [Regression Potential] This driver is only loaded on Hisilicon Hi1620 machines.
