Subject: [PATCH 05/13] SM4 optimization for ARM by HW instruction
This patch implements the SM4 optimization for ARM processor,
using SM4 HW instruction, which is an optional feature of
crypto extension for aarch64 V8.
Tested on some modern ARM micro-architectures with SM4 support, the
performance uplift can be observed around 8X~40X over existing
C implementation in openssl. Algorithms that can be parallelized
(like CTR, ECB, CBC decryption) are on higher end, with algorithm
like CBC encryption on lower end (due to inter-block dependency)
Perf data on Yitian-710 2.75GHz hardware, before and after optimization:
Before:
type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes 16384 bytes
SM4-CTR 105787.80k 107837.87k 108380.84k 108462.08k 108549.46k 108554.92k
SM4-ECB 111924.58k 118173.76k 119776.00k 120093.70k 120264.02k 120274.94k
SM4-CBC 106428.09k 109190.98k 109674.33k 109774.51k 109827.41k 109827.41k
After (7.4x - 36.6x faster):
type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes 16384 bytes
SM4-CTR 781979.02k 2432994.28k 3437753.86k 3834177.88k 3963715.58k 3974556.33k

SM4-CBC 890639.88k 1027746.58k 1050621.78k 1056696.66k 1058613.93k 1058701.31k
