[v2,0/6] Introduce x86 assembly accelerated implementation for SM3 algorithm

Message

tianjia.zhang Dec. 22, 2021, 4:50 a.m. UTC

This series of patches creates an stand-alone library for SM3 hash
algorithm in the lib/crypto directory, and makes the implementations
that originally depended on sm3-generic depend on the stand-alone SM3
library, which also includes sm3-generic itself.

On this basis, the AVX assembly acceleration implementation of SM3
algorithm is introduced, the main algorithm implementation based on
SM3 AES/BMI2 accelerated work by libgcrypt at:
https://gnupg.org/software/libgcrypt/index.html

From the performance benchmark data, the performance improvement of
SM3 algorithm after AVX optimization can reach up to 38%.

v2 changes:
 - x86/sm3: Change K macros to signed decimal and use LEA and 32-bit offset

Tianjia Zhang (6):
  crypto: sm3 - create SM3 stand-alone library
  crypto: arm64/sm3-ce - make dependent on sm3 library
  crypto: sm2 - make dependent on sm3 library
  crypto: sm3 - make dependent on sm3 library
  crypto: x86/sm3 - add AVX assembly implementation
  crypto: tcrypt - add asynchronous speed test for SM3
