Hi, I am researching possibility to use xor_blocks() in crypto_xor() and crypto_xor_cpy(). What I've found already is that different architecture dependent xor functions work on different blocks between 16 and 512 (Intel AVX) bytes long. There is a hint in the comment for async_xor_offs() that src_cnt (as passed to do_sync_xor_offs()) counts pages. Thus, it is assumed, that the smallest chunk xor_blocks() gets is a single page. Am I right? Do you think adding block_len field to struct xor_block_template (and maybe some information about required alignment) and using it to call do_2 from crypto_xor() may work? I am thinking especially about disk encryption where sectors of 512~4096 are handled. Kind regards, -- Łukasz Stelmach Samsung R&D Institute Poland Samsung Electronics
