CBE crypt interface

[Stefan Thöni]

Hello Genodians

We are implementing hardware accelerated encryption for the CBE and have
a question pertaining to this:

How should the Cbe_crypto::Interface be implemented when the underlying
hardware is asynchronous, e.g. driven by interrupts?

I think I understand the semantics of submit_encryption_request and
encryption_request_complete but this mechanism doesn't seem to help with
asynchronous completion. As far as I can tell, no signals are used with
the Cbe_crypto::Interface.

What am I missing?

Best regards
Stefan
