NOTE

How to test the drivers

To test the drivers, under the

"Cryptographic API -> Cryptographic algorithm manager"

kernel configuration sub-menu,

ensure that run-time self tests are not disabled, i.e. the "Disable run-time self tests" entry is not set
(

CONFIG_CRYPTO_MANAGER_DISABLE_TESTS=n

). This will run standard test vectors against the drivers after they register

supported algorithms with the kernel crypto API, usually at boot time. Then run test on the target system. Below is a snippet
extracted from the boot log of ARMv8-based LS1046A platform, with JRI and QI enabled:
