crypto: arm64/sm4 - add ARMv8 Crypto Extensions implementation
This adds ARMv8 implementations of SM4 in ECB, CBC, CFB and CTR modes using Crypto Extensions, also includes key expansion operations because the Crypto Extensions instruction is much faster than software implementations. The Crypto Extensions for SM4 can only run on ARMv8 implementations that have support for these optional extensions. Benchmark on T-Head Yitian-710 2.75 GHz, the data comes from the 218 mode of tcrypt. The abscissas are blocks of different lengths. The data is tabulated and the unit is Mb/s: sm4-generic | 16 64 128 256 1024 1420 4096 ECB enc | 80.05 91.42 93.66 94.77 95.69 95.77 95.86 ECB dec | 79.98 91.41 93.64 94.76 95.66 95.77 95.85 CBC enc | 78.55 86.50 88.02 88.77 89.36 89.42 89.48 CBC dec | 76.82 89.06 91.52 92.77 93.75 93.83 93.96 CFB enc | 77.64 86.13 87.62 88.42 89.08 88.83 89.18 CFB dec | 77.57 88.34 90.36 91.45 92.34 92.00 92.44 CTR enc | 77.80 88.28 90.23 91.22 92.11 91.81 92.25 CTR dec | 77.83 88.22 90.22 91.22 92.04 91.82 92.28 sm4-neon ECB enc | 28.31 112.77 203.03 209.89 215.49 202.11 210.59 ECB dec | 28.36 113.45 203.23 210.00 215.52 202.13 210.65 CBC enc | 79.32 87.02 88.51 89.28 89.85 89.89 89.97 CBC dec | 28.29 112.20 203.30 209.82 214.99 201.51 209.95 CFB enc | 79.59 87.16 88.54 89.30 89.83 89.62 89.92 CFB dec | 28.12 111.05 202.47 209.02 214.21 210.90 209.12 CTR enc | 28.04 108.81 200.62 206.65 211.78 208.78 206.74 CTR dec | 28.02 108.82 200.45 206.62 211.78 208.74 206.70 sm4-ce-cipher ECB enc | 336.79 587.13 682.70 747.37 803.75 811.52 818.06 ECB dec | 339.18 584.52 679.72 743.68 798.82 803.83 811.54 CBC enc | 316.63 521.47 597.00 647.14 690.82 695.21 700.55 CBC dec | 291.80 503.79 585.66 640.82 689.86 695.16 701.72 CFB enc | 294.79 482.31 552.13 594.71 631.60 628.91 638.92 CFB dec | 293.09 466.44 526.56 563.17 594.41 592.26 601.97 CTR enc | 309.61 506.13 576.86 620.47 656.38 654.51 665.10 CTR dec | 306.69 505.57 576.84 620.18 657.09 654.52 665.32 sm4-ce ECB enc | 366.96 1329.81 2024.29 2755.50 3790.07 3861.91 4051.40 ECB dec | 367.30 1323.93 2018.72 2747.43 3787.39 3862.55 4052.62 CBC enc | 358.09 682.68 807.24 885.35 958.29 963.60 973.73 CBC dec | 366.51 1303.63 1978.64 2667.93 3624.53 3683.41 3856.08 CFB enc | 351.51 681.26 807.81 893.10 968.54 969.17 985.83 CFB dec | 354.98 1266.61 1929.63 2634.81 3614.23 3611.59 3841.68 CTR enc | 324.23 1121.25 1689.44 2256.70 2981.90 3007.79 3060.74 CTR dec | 324.18 1120.44 1694.31 2258.32 2982.01 3010.09 3060.99 Signed-off-by: Tianjia Zhang <tianjia.zhang@linux.alibaba.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
