[QUESTION] blkcipher_walk_phys and memory

2009-10-20 Thread Сергей Миронов
Dear all, I have a couple of questions about crypto internals, please help me to understand some concepts. My drivers implements CRYPTO_ALG_TYPE_BLKCIPHER algorithm and has to perform encryption via DMA transfers. I decided to use blkcipher_walk_phys() and blkcipher_walk_done() functions. These fun
