Because > of 'from specification'. That document is short on details, such as the opcodes and machine implementation details (flags, etc). The XMM registers are used. That may be a problem for kernel code. When last I looked openssl did not use /dev/crypt - it's not clear how big the benefit would be from doing this if nothing that uses openssl wins. It might be more beneficial to FreeBSD to patch openssl to use /dev/crypt. If it turns out to not be a significant win then that might hint that the AES opcodes won't be significant win in general either.Received on Mon Mar 08 2010 - 23:10:58 UTC
