Hi all..

How can I run amd64 application in mips64r2 OS. I'm trying multiarch, but doesnt support amd64 in mips64r2 (Octeon CPU/Standart Glibc).

Is It possible ??


Thanks in
advance.

I don't think you can, at least without processor emulation.

Perhaps Qemu? Information on the 'nets is sparse about Qemu running on
MIPS64 hosts, but MIPS32 seems to have been done.

Performance won't be stellar, though...

Having just recently installed Qemu myself and so having at least
wandered around a TINY bit, I honestly wondered if Qemu would help
here after first reading the question. Since it's now officially a
suggestion, I just entered "qemu-" and tab-tabbed in my terminal. Got
this back:

qemu-mips
qemu-mips64
qemu-mips64el
qemu-mipsel
qemu-mipsn32
qemu-mipsn32el

qemu-system-mips
qemu-system-mips64
qemu-system-mips64el
qemu-system-mipsel

Since I'm not versed in "mips" so as to know the difference, I
included all the ones that popped up here on my end in case they
provide any kind of insight into availability of Qemu services. Yeah,
I know, I don't see the "r2" specifically, either. :)

The more I think on that, here's the complete (*extended*) list. I've
only ventured into Qemu long enough to stumble on the necessity of
knowing these are out there but not if there exists more of something
else that complements and/or builds beyond the function of these. My
thought process in sharing is that perhaps there's something there
that MIGHT serve as a viable fallback if you must absolutely
declare/see that "r2":

qemu-aarch64              qemu-ppc                  qemu-system-mips64

Cindy,

if I've understood the original poster, (s)he wants to run X86_64 binaries
on a MIPS64 hardware: that'd be "the other way around" to what we are
used to. Mehmet: did I understand you correctly?

What you've found is very useful in the "normal" case, i.e. you have
an X86_64 hardware and want to run MIPS (32 or 64) binaries.

Regards

But there seems to be something for MIPS32:

  <http://wiki.qemu.org/Features#Host_CPU_support>

(trying to emulate a 64 bit system on that might be a bit slow, though)

Possible, yes.
Viable, no.

The CPU will not understand AMD64 instructions, so they need to be
translated to the host's native CPU instruction set.  This results in a
reduction of performance.  Two options exist for doing this: QEMU and Bochs.

e.g. it's possible to run Linux on an 8-bit AVR (ATMega1284P) computer:
http://hackaday.com/2012/03/28/building-the-worst-linux-pc-ever/

In that case, code to emulate an ARM machine was programmed into the AVR
chip.

Given that MIPS machines are generally both more expensive and slower
than modern AMD64 systems, one has to question the logic in such an
endeavour except maybe to prove it can be done.

I haven't lost my mind...
