AMD Bulldozer and aesni driver

[Mario Fleischmann]

I'm wondering if the aesni module in FreeBSD 9.0 does support the
current AMD FX CPUs. The manpage explicitly states support for Intel
CPUs, but since AMD licensed AES-NI from Intel, I think it should also
work with the current Bulldozer lineup.

Does anyone have experience with aesni regarding the current Zambezi cores?

Regards,
Mario Fleischmann

Still no info on this?
I am also about to buy a bulldozer, but I need to know if the aesni driver
supports the bulldozer.
Please anyone already using it?

Hi!

aesni(4) driver detects the module on Bulldozer fine.
I was happy to see it first but then I found out that openssl that goes
as part of FreeBSD distribution lacks AESNI engine module.
There are some patches for bringing aesni into FreeBSD mentioned on
forums but this in not a production-system-running approach for me.
So the answer is YES - it exists, but right then NO - it does not work.

What patches are you talking about? There is an official aesni driver
http://www.freebsd.org/cgi/man.cgi?query=aesni&sektion=4&manpath=FreeBSD+8.2-RELEASE
And it does work for intel.
Sorry I didnt quite understand you fully. Do you mean it does not work
in general?

Hi!

I mean that most of software which utilizes encryption relies on OpenSSL
library. It looks that current version of OpenSSL in FreeBSD cannot use
aesni as hardware accelerator, so all that software cannot benefit from
using aesni.

On the other hand there is stuff like ipsec and geli which relies on
crypto(9) framework. This may use aesni accelerator. Unfortunately the
machine with Bulldozer that I have use neither of them so I cannot tell
how significant improvement is.
