Jussi Kivilinna c456a9cd1a crypto: aesni_intel - add more optimized XTS mode for x86-64 ... Add more optimized XTS code for aesni_intel in 64-bit mode, for smaller stack usage and boost for speed. tcrypt results, with Intel i5-2450M: 256-bit key enc dec 16B 0.98x 0.99x 64B 0.64x 0.63x 256B 1.29x 1.32x 1024B 1.54x 1.58x 8192B 1.57x 1.60x 512-bit key enc dec 16B 0.98x 0.99x 64B 0.60x 0.59x 256B 1.24x 1.25x 1024B 1.39x 1.42x 8192B 1.38x 1.42x I chose not to optimize smaller than block size of 256 bytes, since XTS is practically always used with data blocks of size 512 bytes. This is why performance is reduced in tcrypt for 64 byte long blocks.
