I started porting fixes from SoCBSD to FreeBSD https://github.com/SoCBSD/socbsd-src
RPI2/RPI3 got 3d acceleration, which dropped memory usage from 500mb to about 180mb..
It also fixed few locks on the way.
If you are someone that want to learn programming, a SoC with 2 SDcard is excellent learning target. RPI2/3/4/5 can be found cheaply in facebook marketplace.
Grab them before people start installing LittleFedi on them or full servers in FreeBSD.
