[Pkg-openssl-devel] OpenSSL OCF HW acceleration (AMD LX800)

[Teco Boot]

Hi,

I'm using OpenVPN, but struggling with performance on Alix embedded systems, with AMD LX800 CPU.
The CPU has crypto HW acceleration, and this is supported by recent Linux, with OCF.
I use Voyage Linux, which is Debian with some tools for embedded devices.

The Voyage Linux maintainer patched OpenSSL/SSHD before, but he stopped doing this.

OCF is on my system:
> root at voyage:~# modprobe ocf ; modprobe cryptodev ; modprobe cryptosoft
> root at voyage:~# lsmod | grep "crypto"    
> cryptosoft             10371  0 
> cryptodev               8782  0 
> ocf                    16698  2 cryptosoft,cryptodev


The patch from ocf-linux doesn't work for 1.0.1c. I tried patch for 0.9.8r.
> root at voyage:~/openssl-src/openssl-1.0.1c# patch -p1 < openssl-0.9.8r.patch 

This didn't work.

Q:
Is there any effort on OpenSSL for HW acceleration (so I don't need OCF-linux provided patches)?
If OCF is the way to go, why not adopt it?

I guess the questions are for OpenSSL development. I try you as Debian maintainers first. Feel free to forward.

Thanks,
Teco
