crypto: hisilicon - update SEC driver module parameter (57b1aac1) · Commits · 戴 / test

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. Signed-off-by:
