I think it depends on what you'd like to do. Here at the house I have the following status: - on hard drive: 10.2-PRERELEASE FreeBSD 10.2-PRERELEASE #0 r284970: Wed Jul 1 03:30:12 UTC 2015, up 72 days, 13:58. This is building packages. - netboot: sparc64-10 20151230 working. - netboot: sparc64-11 20151222 fails: "panic: pcib0: fatal DMC/PEC error" > I'd like to do some work on the bootloader and installer (zfs from > installer would be nice) I know there is some work being done on the bootloader for x86. I do not know if this carries over to non-x86. Hopefully someone on arch@ will comment. If not, please ping me offline. > and of course sun4v. A build of sun4v from 8-STABLE (last version it existed) on 20151120 just hangs. I believe the netboot setup is the same as for the above, with 90% confidence. IMHO it's going to take a great deal of work. I will probably only tinker with it from time to time. > It seems what needs the most attention is the build toolchain, am I > correct? Correct. There was some discussion earlier in the thread about "external toolchain support". This would allow us to use various gcc/clangs without having them in the base system. This would also help us out on various of the other tier-2 archs (in particular, those for arm/mips). I do not know the latest state. Perhaps a check of the freebsd-toolchain@ archives might help. If not, email me offline and I'll put you in touch with the right people. This is going to be a very involved task, however, so FYI. > I think clang is not really considerable at the moment We took a look at it several weeks ago and it needed help. I can put you in touch with the person who was interested. > This would be my first real contribution to FreeBSD, so any pointers > or docs are graciously accepted. First, thanks for the offers :-) Second, please be patient when waiting for answers. sparc64 support is on a "as time is available" status and not many developers prioritize it. I split my time between it and powerpc64 and ports work. I'll email you some of the basic documentation pointers offline from this discussion. mcl
