[Qemu-devel] QEMU emulate Shared-ISA multi-core architecture.

[Shiao-Hui Chiu]

hello, all

I am trying to configure a Shared-ISA multi-core architecture, and I
just configure the cpu_model with two different types,
one is core2duo, the other one is pentium3. ( some instruction set is
not supporting in pentium3 )
then I verify this architecture with a simple program that I expect
some instruction will have exception at pentium3 cpu, but
execute correct at core2duo cpu.

In my experiment, sometimes i got wrong results,
for example, program had exception at pentium3, but next time i ran
the same program at core2duo, it still got a exception.

i have no idea about that,
and i guess maybe it has something in cache?
