Patch adds 3-way parallel x86_64 assembly implementation of twofish as new module. New assembler functions crypt data in three blocks chunks, improving cipher performance on out-of-order CPUs. Patch has been tested with tcrypt and automated filesystem tests. Summary of the tcrypt benchmarks: Twofish 3-way-asm vs twofish asm (128bit 8kb block ECB) encrypt: 1.3x speed decrypt: 1.3x speed Twofish 3-way-asm vs twofish asm (128bit 8kb block CBC) encrypt: 1.07x speed decrypt: 1.4x speed Twofish 3-way-asm vs twofish asm (128bit 8kb block CTR) encrypt: 1.4x speed Twofish 3-way-asm vs AES asm (128bit 8kb block ECB) encrypt: 1.0x speed decrypt: 1.0x speed Twofish 3-way-asm vs AES asm (128bit 8kb block CBC) encrypt: 0.84x speed decrypt: 1.09x speed Twofish 3-way-asm vs AES asm (128bit 8kb block CTR) encrypt: 1.15x speed Full output: http://koti.mbnet.fi/axh/kernel/crypto/tcrypt-speed-twofish-3way-asm-x86_64.txt http://koti.mbnet.fi/axh/kernel/crypto/tcrypt-speed-twofish-asm-x86_64.txt http://koti.mbnet.fi/axh/kernel/crypto/tcrypt-speed-aes-asm-x86_64.txt Tests were run on: vendor_id : AuthenticAMD cpu family : 16 model : 10 model name : AMD Phenom(tm) II X6 1055T Processor Also userspace test were run on: vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Xeon(R) CPU E7330 @ 2.40GHz stepping : 11 Userspace test results: Encryption/decryption of twofish 3-way vs x86_64-asm on AMD Phenom II: encrypt: 1.27x decrypt: 1.25x Encryption/decryption of twofish 3-way vs x86_64-asm on Intel Xeon E7330: encrypt: 1.36x decrypt: 1.36x Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> |
