[CRYPTO] twofish: i586 assembly version
The patch passed the trycpt tests and automated filesystem tests. This rewrite resulted in some nice perfomance increase over my last patch. Short summary of the tcrypt benchmarks: Twofish Assembler vs. Twofish C (256bit 8kb block CBC) encrypt: -33% Cycles decrypt: -45% Cycles Twofish Assembler vs. AES Assembler (128bit 8kb block CBC) encrypt: +3% Cycles decrypt: -22% Cycles Twofish Assembler vs. AES Assembler (256bit 8kb block CBC) encrypt: -20% Cycles decrypt: -36% Cycles Full Output: http://homepages.tu-darmstadt.de/~fritschi/twofish/tcrypt-speed-twofish-asm-i586.txt http://homepages.tu-darmstadt.de/~fritschi/twofish/tcrypt-speed-twofish-c-i586.txt http://homepages.tu-darmstadt.de/~fritschi/twofish/tcrypt-speed-aes-asm-i586.txt Here is another bonnie++ benchmark with encrypted filesystems. All runs with the twofish assembler modules max out the drivespeed. It should give some idea what the module can do for encrypted filesystem performance even though you can't see the full numbers. http://homepages.tu-darmstadt.de/~fritschi/twofish/output_20060611_205432_x86.html Signed-off-by: Joachim Fritschi <jfritschi@freenet.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
