How to use cryp1 and cryp2 hardware in STM32MP157C

Hi,

 

Currently I am working on how to use use cryp1 and cyp2 hardware efficiently. How to know it is using crypto hardware when working with openssl. how to check the efficiency?

Currently these configurations are enabled in my kernel.

CONFIG_CRYPTO_DEV_STM32_CRC=y
CONFIG_CRYPTO_DEV_STM32_HASH=y
CONFIG_CRYPTO_DEV_STM32_CRYP=y

 

but still I am not able see /dev/crypto dev is listed.

Currently my cat /proc/crypto output is something like this

Hi @VarunKumar 

 

Same question has already been treated in this Forum. Did you try to search ? 

 

Let me know

Hi @olivier

 

Thank you for the reply. I did went through the forum but did not get some info on how to confirm its using crypto hardware.

Can you please get me some forum links that you know so that I can refer that and check?

Hi 

Thank you. I got few references.
