From ecc8bc81f2fb3976737ef312f824ba6053aa3590 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Wed, 3 Jul 2019 10:55:11 +0200 Subject: crypto: aegis128 - provide a SIMD implementation based on NEON intrinsics Provide an accelerated implementation of aegis128 by wiring up the SIMD hooks in the generic driver to an implementation based on NEON intrinsics, which can be compiled to both ARM and arm64 code. This results in a performance of 2.2 cycles per byte on Cortex-A53, which is a performance increase of ~11x compared to the generic code.
