If anyone on FreeBSD wants to try this I just added a port under archivers/lzfse

Docker does run of FreeBSD but it heavily relies on ZFS and the 64bit Linux compatibility layer.

While I am sure that Sony has code that they keep proprietary, its worth noting that thy have contributed quite a bit back to FreeBSD (AVX support comes to mind) as well as LLVM.

There has been quite a bit of work done to make cross compiling packages for ARM with poudriere. A fairly good tutorial on how to set that up can be found at https://forums.freebsd.org/threads/building-arm-packages-wit...

FreeBSD has full support for GPIO and i2c on both the RPi 1 and 2. Simple wrappers around FreeBSD's GPIO ioctl can be found at https://github.com/gonzoua/freebsd-gpio

I'm more curious if WiringPi is usable or ported over?

Come join the FreeBSD documentation team and help improve what is already considered world class documentation

Its far too good to need help. Clearly they want to show a before after comparison...

Don't forget OpenCVS

If you are interested in creating a FreeBSD image for the Raspberry Pi, take a look at crochet [1] which is a script that pretty much automates the steps outlined in the wiki. In addition, it can also be used to create images for Beaglebone and other ARM (and MIPS I believe) platforms

They have set a goal of raising $150,000 for 2014 so if you haven't already, please consider donating

They actually have several developers on staff and most of the work they are doing ends up getting committed back to head
