It looks like the 32 bit one should work fine. I haven't played with 64 bit yet but there's some support for it in the tree, give it a try? http://en.wikipedia.org/wiki/Loongson Heh. The background on the "4 patented instructions" mentioned above is mips' lawsuit against Lexra many years ago: http://landley.net/notes-2009.html#14-12-2009 If you were wondering why mips had a lost decade where most of its customers switched over to arm, convincing the world you're a patent troll will do that. But it's been well over a decade and most people seem to have forgotten now. And china never cared about US intellectual property infighting anyway... > But I wonder if anyone have used qemu/kvm virtualization with China loongson > processor (MIPS architecture) without modification of qemu/kvm code. > All the infomation I have searched in the Internet can't answer my question. I have a mips r4k system emulation working fine at: http://landley.net/aboriginal/bin/system-image-mips.tar.gz (That's based off of linux 3.18 I think, I have 3.19 building locally, 4.0 is on the todo list.) I haven't tried 64 bit yet but: $ qemu-system-mips64 -cpu ? | grep Loongson MIPS 'Loongson-2E' MIPS 'Loongson-2F' It's apparently there... Rob
