Hi,
I am trying to add support for MIPS 64 as Host machine as my academic
project.
I am new to QEMU.
Problem is I dont have a MIPS 64 machine to test on.
Please suggest whether or not I can use a nested QEMU emulator to test the
same.
i.e. running my version on top of a simulated MIPS64 machine.
Is it possible to do so?

Note that some work has already been done for MIPS host
support.

I was able to run on an x86_64 host, an ARM-hosted QEMU simulating
x86. That was for Linux user mode. I can't say if that would work for
other targets or for system simulation.

Can you tell me what is the status of adding MIPS64 support?
as at the wiki page it showed Red earlier.

Unfortunately, you won't get further for now. There's a cache problem
leading to bad relocation (in case of relocations, jump to label are
"transformed" into jump to next instruction). See linux-mips mailing
list, there was on thread about it.

A company called lemote[1] sells laptop and mini-PC based MIPS
CPU ,loongson[2],a 800M 64-bit four-issues out-of-order execution
Superscalar architecture. Quad-Core Loongson-3 Processor has been taped
out by ST Microelectronics. Currently,I run qemu on my loongson
computer,but qemu crashs during booting.
