crypto: blowfish - add x86_64 assembly implementation
Patch adds x86_64 assembly implementation of blowfish. Two set of assembler functions are provided. First set is regular 'one-block at time' encrypt/decrypt functions. Second is 'four-block at time' functions that gain performance increase on out-of-order CPUs. Performance of 4-way functions should be equal to 1-way functions with in-order CPUs. Summary of the tcrypt benchmarks: Blowfish assembler vs blowfish C (256bit 8kb block ECB) encrypt: 2.2x speed decrypt: 2.3x speed Blowfish assembler vs blowfish C (256bit 8kb block CBC) encrypt: 1.12x speed decrypt: 2.5x speed Blowfish assembler vs blowfish C (256bit 8kb block CTR) encrypt: 2.5x speed Full output: http://koti.mbnet.fi/axh/kernel/crypto/tcrypt-speed-blowfish-asm-x86_64.txt http://koti.mbnet.fi/axh/kernel/crypto/tcrypt-speed-blowfish-c-x86_64.txt Tests were run on: vendor_id : AuthenticAMD cpu family : 16 model : 10 model name : AMD Phenom(tm) II X6 1055T Processor stepping : 0 Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
