Taehee Yoo	37d8d3ae7a	crypto: x86/aria - implement aria-avx2 ... aria-avx2 implementation uses AVX2, AES-NI, and GFNI. It supports 32way parallel processing. So, byteslicing code is changed to support 32way parallel. And it exports some aria-avx functions such as encrypt() and decrypt(). There are two main logics, s-box layer and diffusion layer. These codes are the same as aria-avx implementation. But some instruction are exchanged because they don't support 256bit registers. Also, AES-NI doesn't support 256bit register. So, aesenclast and aesdeclast are used twice like below: vextracti128 $1, ymm0, xmm6; vaesenclast xmm7, xmm0, xmm0; vaesenclast xmm7, xmm6, xmm6; vinserti128 $1, xmm6, ymm0, ymm0; Benchmark with modprobe tcrypt mode=610 num_mb=8192, i3-12100: ARIA-AVX2 with GFNI(128bit and 256bit) testing speed of multibuffer ecb(aria) (ecb-aria-avx2) encryption tcrypt: 1 operation in 2003 cycles (1024 bytes) tcrypt: 1 operation in 5867 cycles (4096 bytes) tcrypt: 1 operation in 2358 cycles (1024 bytes) tcrypt: 1 operation in 7295 cycles (4096 bytes) testing speed of multibuffer ecb(aria) (ecb-aria-avx2) decryption tcrypt: 1 operation in 2004 cycles (1024 bytes) tcrypt: 1 operation in 5956 cycles (4096 bytes) tcrypt: 1 operation in 2409 cycles (1024 bytes) tcrypt: 1 operation in 7564 cycles (4096 bytes) ARIA-AVX with GFNI(128bit and 256bit) testing speed of multibuffer ecb(aria) (ecb-aria-avx) encryption tcrypt: 1 operation in 2761 cycles (1024 bytes) tcrypt: 1 operation in 9390 cycles (4096 bytes) tcrypt: 1 operation in 3401 cycles (1024 bytes) tcrypt: 1 operation in 11876 cycles (4096 bytes) testing speed of multibuffer ecb(aria) (ecb-aria-avx) decryption tcrypt: 1 operation in 2735 cycles (1024 bytes) tcrypt: 1 operation in 9424 cycles (4096 bytes) tcrypt: 1 operation in 3369 cycles (1024 bytes) tcrypt: 1 operation in 11954 cycles (4096 bytes) Signed-off-by: Taehee Yoo <ap420073@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>	2023-01-06 17:15:47 +08:00
