[Qemu-devel] Simulating a composite machine

[Martin Schroeder]

Is it possible to instantiate multiple CPUs of different architectures
and simuate them with different images at the same time? Some examples
include ARM socs with m3/m4 coprocessor core but also boards with
multiple processors where it is desirable to connect the chips over
for example virtual SPI or UART and then simulate the composite system
as a single machine where each of the cores runs a separate firmware.

Is something like this easy to implement given current processor
objects or does this require substantial changes to how qemu works?
One area I do not fully understand is native code generator and
whether it would be able to cope with two cores of *different*
architectures at the same time.
