Setting up the cryptographic device driver

Configure the cryptographic device driver through the ap.domain= and the ap.poll_thread= kernel parameters. You might also have to set up libraries.

The cryptographic device driver consists of multiple, separate modules:
zcrypt
Cryptographic Coprocessor interface, Cryptographic Coprocessor message type 6, Cryptographic Coprocessor message type 50. Support for message type 6 includes secure key and RNG requests. Support for message type 50 includes RSA requests for both modulus-exponent and Chinese-Remainder Theorem variants.
zcrypt_cex4
device driver for CEX6, CEX5, and CEX4 adapters.
zcrypt_cex2a
device driver for CEX3A adapters.
zcrypt_pcixcc
device driver for CEX3C adapters.
