verify caam used?

gbiradar — Fri, 19 Feb 2016 09:31:11 GMT

Hi Guys,

i have implemented libsrtp which uses cryptodev engine with openssl. Some how i'm able to stream video for 10 seconds,

in this forum i read that if any application uses caam then count will be raised for caam in cat /proc/interrupts. But coming to verify whether our application is using caam hardware encryption we pass the command

"cat /proc/interrupts | grep caam" -> blank output.

when i have passed lsmod it show cryptodev being used count is increased from "0" to "1".

My question is how do i verify caam is being used or not.

regards,

Ganesh Biradar

As I konwn, litb has unit test (imx-test pacakge ) which can test caam module.

Hi joanxie

i'm using yocto 1.7 poky, kernel version is 3.14. I used bitbake imx-test -c compile/build -f.

it generated imx-test application but in that i didn't find any binaries to test caam.

one doubt: Are you talking about tcrypt.ko file.

you also can use SDK which provides executable images, running on the target board like imx6q board
