Spent some time yesterday imporing improved arm64 string functions into the FreeBSD kernel. Saw a 14% improvement in system & 9% real time for buildkernel on some HW. (Thanks @freebsdfndation & @AmpereComputing)

160 cores should be enough? (Thanks to @AmpereComputing for getting an Altra to @freebsdfndation for us to test #FreeBSD)

I’d roll my eyes in Australian but I’ve lived in London I know how bad it was in the low 30s so 40 is going to be awful.

16k pages on #FreeBSD #arm64 is showing a nice performance improvement for buildkernel.

👇 This could change how we secure data. Our new SoC and demonstrator board, based on CHERI with @Cambridge_CL, contains the first example of the Morello prototype architecture, enabling enhanced security from the hardware level. It's in testing now: bit.ly/3GFKUZH

Thanks to Intel ME I always get nervous when someone mentions chip-level security... However, the #Morello project sounds interesting: it combines @Arm chips and @FreeBSD: freebsdfoundation.org/news-a… so, two interesting technologies!

FreeBSD Essential to Bringing CHERI and ARM’s Morello Processor to Life | FreeBSD Foundation

Exciting news coming out of ARM, the University of Cambridge, and SRI today. Cambridge and SRI released their CHERI software stack, based on FreeBSD, for ARM’s forthcoming experimental Morello board....

ARM's announced the ship of the Morello boards! I'm very excited to share a new blogpost from Microsoft Research and MSRC, sharing some insights and thoughts regarding our future work on this front! msrc-blog.microsoft.com/2022…

We still need to get debugging working before we build userspace with it enabled, but that's mostly ready.
