random(4) overheads question

I'm working on a demon that collects timer randomness, distills it some, and pushes the results into /dev/random. My code produces the random material in 32-bit chunks. The current version sends it to /dev/random 32 bits at a time, doing a write() and an entropy-update ioctl() for each chunk.

[PATCH 2/3] crypto: twofish-x86-asm: make assembler functions use twofish_ctx instead of crypto_tfm

This needed by 3-way twofish patch to be able to easily use one block assembler functions. As glue code is shared between i586/x86_64 apply change to i586 assembler too. Also export assembler functions for 3-way parallel twofish module. CC: Joachim Fritschi jfrits...@freenet.de Signed-off-by:

[PATCH 3/3] crypto: twofish: add 3-way parallel x86_64 assembler implemention

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:

[PATCH v4 00/17] crypto user configuration api
