Porting FreeBSD to Loongson 3A (RS780e)

Well given none of the Loongson chips are server chips and none of the
current builds (AFAIK) support ECC RAM, and since Lemote is selling a laptop
with the 3A (not a server) I don't think the 3A is a server chip. And I
really don't care, because the Loongson works fine for a home server, even
the lowly 2F.

Ok, but OpenBSD and Debian already Loongson 2F so how hard can it be, given
the code already exists and in the case of OpenBSD comes with a good
license... and Loongson 2F is MIPS III compatible and runs 64 or 32 bit mode
executables. What does the "mips64r2" give you beyond MIPS III?

Support is already available in OpenBSD for 2E and 2F. Personally I am happy
with OpenBSD but I would also be happy to see as many OS as possible
supporting Loongson because I think MIPS is a good architecture and there
haven't been many general purpose machines made since SGI got out of the
workstation business. And Lemote is a good company...
