Status update for FreeBSD on the RPI3: 1) There is now a sysutils/u-boot-rpi3 port. Thanks Diane Bruce! 2) Using clang 3.9.0 + lld in base, one can build and install some ports with a few workarounds. boot1.efi, loader.efi, and the kernel need to come from a non-clang 3.9.0 branch (HEAD). 3) jemalloc has issues on the RPI3, can be worked around by disabling tcache via malloc.conf. Diane Bruce ponders whether this could be related to locking on arm64. 4) linking dynamically-loaded executables (via installing ports entries) has issues 5) SMP support is being actively worked on by Diane Bruce 6) I need to update the documentation to use the u-boot-rpi3 port 7) I need to update the documentation to use crochet now that crochet supports the rpi3 and we have the u-boot-rpi3 port All this has been documented in more detail at the RP3 wiki page: https://wiki.freebsd.org/arm64/rpi3 I'm going to start researching in more detail the jemalloc and dynamic linking issues this weekend. If someone gets to it sooner than me, then yay! Otherwise, I'm happy to take a gander. Again, if anyone has any suggestions for the documentation, please let me know.
