Can you test this following patch which have sent this lkml to enable
sec2 driver for ubuntu verson?
[PATCH] crypto: hisilicon - update SEC driver module parameter
As stress-ng running SEC engine on the Ubuntu OS,
we found that SEC only supports two threads each with one TFM
based on the default module parameter 'ctx_q_num'.
If running more threads, stress-ng will fail since it cannot
get more TFMs.
In order to fix this, we adjusted the default values
of the module parameters to support more TFMs.
