Security Engine of LS1021A

[tecuelee]

I am currently being developed based on LS1021A-IoT.
I have a difficulty with respect to Security engine.
I try to change the api using security engine instead using S/W openssl.
It applied as follows, but there is little change in speed.

root@OpenWrt:/# modprobe cryptodev
[             ] cryptodev: driver 1.8 loaded
root@OpenWrt:/# openssl engine
(cryptodev) BSD cryptodev engine
(dynamic) Dynamic engine loading support

What went wrong? Or seek advice.

Enabling cryptodev driver alone does not offload crypto jobs to the

hardware. You should also enable the hardware (CAAM in your case)

driver. Suggestions:

1. Use NXP QorIQ SDK:

2. Follow the SDK documentation:

Have a great day,

Dear bpe

I thank you for your quick reply

My situation is the same

root@OpenWrt:/# modprobe cryptodev

cryptodev: driver 18 loaded

root@OpenWrt:/# openssl version

OpenSSL 101g 7 Apr 2014

root@OpenWrt:/# openssl engine

(cryptodev) BSD cryptodev engine

(dynamic) Dynamic engine loading support

root@OpenWrt:/# modprobe tcrypt

modprobe: FATAL: Module tcrypt not found

root@OpenWrt:/# grep tls /proc/crypto

name         :

tls10(hmac(sha1),cbc(aes))

driver       : tls10-hmac-sha1-cbc-aes-caam

root@OpenWrt:/# cat /proc/interrupts | grep -i qman

root@OpenWrt:/#

root@OpenWrt:/# cat /proc/interrupts | grep jr

How can I check the CAAM features on LS1021A-IoT platforms?

How can I use the Security engine acceleration with OpenSSL, cryptodev,

CAAM?

My company is a company that specializes in the development api

Perhaps, is there any sample application that can use CAAM features?
