And I really don't care, because the Loongson works fine for a home server, even the lowly 2F. > No.2, loongson 3a is mips64r2 compatible just like XLP832 and Octeon 6330 > which are already supported in FreeBSD/MIPS, and the chipset rs780e > for 3a is a common 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? > hardware, we can easily porting freebsd to 3a. > No.3, loongson 3a is the first cpu in Loongson 3, 3b is pin-to-pin > compatible to 3a, if we got 3a brought up > 3b is easy, 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... -- _ ASCII ribbon campaign ( ) Powered by Lemote Fuloong against HTML e-mail X Loongson MIPS and OpenBSD and proprietary / \ Mutt.org attachments Code Blue or Go Home!
