Jussi Kivilinna 937c30d7f5 crypto: serpent - add 8-way parallel x86_64/SSE2 assembler implementation ... Patch adds x86_64/SSE2 assembler implementation of serpent cipher. Assembler functions crypt data in eigth block chunks (two 4 block chunk SSE2 operations in parallel to improve performance on out-of-order CPUs). Glue code is based on one from AES-NI implementation, so requests from irq context are redirected to cryptd. v2: - add missing include of linux/module.h (appearently crypto.h used to include module.h, which changed for 3.2 by commit 7c926402a7) Patch has been tested with tcrypt and automated filesystem tests. Tcrypt benchmarks results (serpent-sse2/serpent_generic speed ratios): AMD Phenom II 1055T (fam:16, model:10): size ecb-enc ecb-dec cbc-enc cbc-dec ctr-enc ctr-dec 16B 1.03x 1.01x 1.03x 1.05x 1.00x 0.99x 64B 1.00x 1.01x 1.02x 1.04x 1.02x 1.01x 256B 2.34x 2.41x 0.99x 2.43x 2.39x 2.40x 1024B 2.51x 2.57x 1.00x 2.59x 2.56x 2.56x 8192B 2.50x 2.54x 1.00x 2.55x 2.57x 2.57x Intel Celeron T1600 (fam:6, model:15, step:13): size ecb-enc ecb-dec cbc-enc cbc-dec ctr-enc ctr-dec 16B 0.97x 0.97x 1.01x 1.01x 1.01x 1.02x 64B 1.00x 1.00x 1.00x 1.02x 1.01x 1.01x 256B 3.41x 3.35x 1.00x 3.39x 3.42x 3.44x 1024B 3.75x 3.72x 0.99x 3.74x 3.75x 3.75x 8192B 3.70x 3.68x 0.99x 3.68x 3.69x 3.69x Full output: http://koti.mbnet.fi/axh/kernel/crypto/phenom-ii-1055t/serpent-generic.txt http://koti.mbnet.fi/axh/kernel/crypto/phenom-ii-1055t/serpent-sse2.txt http://koti.mbnet.fi/axh/kernel/crypto/celeron-t1600/serpent-generic.txt http://koti.mbnet.fi/axh/kernel/crypto/celeron-t1600/serpent-sse2.txt Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>		2011-11-21 16:13:23 +08:00
