This patchsets exported some of the common functions implemented by
the SM4 AESNI/AVX algorithm, and reused these functions to achieve
the acceleration of AESNI/AVX2 implementation.
The main algorithm implementation comes from SM4 AES-NI work by
libgcrypt and Markku-Juhani O. Saarinen at:
https://github.com/mjosaarinen/sm4ni
Benchmark on Intel i5-6200U 2.30GHz, performance data of three
implementation methods, pure software sm4-generic, aesni/avx
acceleration, and aesni/avx2 acceleration, the data comes from
the 218 mode and 518 mode of tcrypt. The abscissas are blocks of
different lengths. The data is tabulated and the unit is Mb/s:

From the benchmark data, it can be seen that when the block size is
1024, compared to AVX acceleration, the performance achieved by AVX2
has increased by about 70%, it is also 7.7 times of the pure software
implementation of sm4-generic.
