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. _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
