Re: [Ocf-linux-users] Clarification regarding kernel talitos & OCF talitios driver

[Shivdas G. <shi...@gm...>]

Hi David,

thanks for your prompt reply.

So, do you have  any idea how drivers/crypto/talitos.c driver is
accessible via userspace,
much like how OCF taltios driver is accessible to openssl via /dev/crypto.

I am not able to find as of the interface from userspace to the kernel
driver drivers/crypto/talitos.c.

Thanks and Regards,
Shihvdas Gujare
