From my POV this is not asynchronous at all (see my comments inline), but maybe Herbert can confirm that.Well we don't actually require drivers to be asynchronous. It is obviously the preferred method but some hardware may not be capable of that.
Yep, but then they shouldn't be declared with CRYPTO_ALG_ASYNC and as an ablkcipher algorithm (*Asynchronous* Block Cipher), right ? Regarding the capabilities of this crypto engine, from what I've seen, it is definitely capable of doing asynchronous requests ;-).
