2013-04-25crypto: x86 - add more optimized XTS-mode for serpent-avxJussi Kivilinna
This patch adds AVX optimized XTS-mode helper functions/macros and converts serpent-avx to use the new facilities. Benefits are slightly improved speed and reduced stack usage as use of temporary IV-array is avoided. tcrypt results, with Intel i5-2450M: enc dec 16B 1.00x 1.00x 64B 1.00x 1.00x 256B 1.04x 1.06x 1024B 1.09x 1.09x 8192B 1.10x 1.09x Signed-off-by: Jussi Kivilinna <jussi.kivilinna@iki.fi> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2012-10-24crypto: x86/glue_helper - use le128 instead of u128 for CTR modeJussi Kivilinna
'u128' currently used for CTR mode is on little-endian 'long long' swapped and would require extra swap operations by SSE/AVX code. Use of le128 instead of u128 allows IV calculations to be done with vector registers easier.

2012-10-04crypto: x86/glue_helper - fix storing of new IV in CBC encryptionJussi Kivilinna
Glue_helper incorrectly XORs new IV over old IV at end of CBC encryption function when it should store. This causes CBC encryption to give incorrect output on multi-page encryption requests.

2012-06-27crypto: serpent-sse2 - split generic glue code to new helper moduleJussi Kivilinna
Now that serpent-sse2 glue code has been made generic, it can be split to separate module. Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
