I mean how it is implemented now in crypto API, and I was almost sure that aes-ni acceleration code uses cryptd (iow real asynchronous processing) and also that not all CPU cores can run these instruction in parallel. So I am mistaken here? Milan -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
