Hi, This is great news for me with my home HPE ML110 G10/Xeon 4108 server. However, I will not be able to test this patch unless it can get backported to 12.1 or 12.2 once it's out, and I don't expect backporting to happen. I have one question about this: will I be able to use this to accelerate OpenSSL? Is additional code needed? I use the mentioned HPE server for Tor and Tor is very crypto-heavy (yet singlethreaded). I believe the official Intel drivers allow OpenSSL acceleration, but I'd prefer to avoid out-of-band drivers whether possible (ports/src is fine). -Neel === https://www.neelc.org/ On 2020-10-26 13:00, Mark Johnston wrote: > Hi, > > I did a port of NetBSD's qat(4) to FreeBSD for pfSense, and made some > enhancements.
