I'm dying to get one of these for over a year now... nooooo place I can find them! :roll:

http://www.loongson.cn/product_info.php?id=36

or at worst one of the single socket quad's (blue board).

Dual quad-core 1ghz Loongson-3F. Okay.. I'm at work.. no MIPS porn.

This is interesting. If you learn anything, keep us updated.

Absolutely! There's also a site by a fellow called mat888 afair. I managed to stumble upon him on IRC, but alas he has heard nothing either. :(

Same for the laptop if anyone spots them in the wild, or even better wants to do a bulk buy. I notice on alibaba there a lemote store there flogging older model MIPS jobs, but nothing dual core or close to this model. My netbook is holding out, desperately want to replace it with a MIPS based system.

Well, if it's unobtainable, then I'm assuming technical documentation isn't either, and therefore use to substitute to an irix system is as well.

Well that's the most interesting rendering of my username I've seen yet.

Anyway, the link he's talking about is http://mattst88.com/blog/2010/11/12/The_Loongson_3A_(Godson_3A)_looks_nice!/

Wow. IRIX is never going to happen. Stop thinking about it.

Irix may not, but I seem to remember that binary emulation might make it possible for linux/*bsd to run irix binaries on mips-"like" cpus. With this in mind, this precludes GL applications, and most likely any possible graphical applications, although remains a subset of applications that could be a good candidate for such hardware. With this in mind, I am interested by this project.

You don't need unreleased hardware to do that. Go ahead and do it.

Well, let's wait until they're released so we can look at some pricing there. Needless to say I have a few binary apps I'd be willing to run on this. Matt, would you happen to know which ballpark they will be available at and/or a release date? My Chinese isn't terribly great; and you seem to know the right people.

Thanks!

Sorry, I don't know. I'm just an interested Gentoo/MIPS developer.

Seriously though, if you're capable of writing support for IRIX applications, not having a Loongson 3 wouldn't prevent you from doing it. And if you're not capable, a Loongson 3 won't help.

hi matt, sorry for out of topic, just have a quick question on gentoo, i was able to use gentoo on my octane and o2 using the live CD.
but both using a vga monitor. if use my o2 with 1600sw, i cant see any display maybe need to set the resolution? my question is is it possible and were you able to boot gentoo live CD on an O2 + 1600SW? if yes can you please let me know how to do it? thanks in advance :)

Interesting. I've never had a 1600SW, so I've never tried. You might want to ask Kumba in the #gentoo-mips IRC channel on Freenode.

The MIPS CPU is going to be the smallest part of the emulation issues, so instead of worrying about how new CPU "x" does things differently from a R10k you might as well write an R10k emulator for x86-64. Then you get to move on to the fun stuff - all of the proprietary SGI chips with unreleased (and probably lost) documentation. The net result of all that work would be a much more useful setup than something that kind of works kludged around a MIPS system that might be absent or substantially changed in a year.

For graphics, I think I'd start out trying to emulate an ODYSSEY, since the input is pretty straight OpenGL, leaving you with HEART and XBOW to wrestle with.

The other tack would be to emulate Indy, since Indy XL documentation was released by SGI. Perhaps not as useful, but an easier start.

I'm not sure you get it, it's not emulation, it's binary translation, netbsd had it for a decade, and it works great.

I'm not interested in graphics, what so ever. I've considered running it under quicktransit on itanium, but I doubt that's worth a try.
