Hi,
We are trying to run guest SMP code with qemu icount mode, but based on my current understanding I don’t think we can do that, because with icount enabled, the multi cpus will be simulated in round-robin way(tcg kick vcpu timer, or current
cpu exit in order to handle interrupt or the ending of the current execution translationblock) with the single vCPU thread, so qemu is not running guest code in parallel as real hardware does, if guest code has the assumption cores run in parallel it will
cause unexpected behavior.
I’m fresh man to QEMU and not sure whether the understanding is correct or not, so appreciate any comment, thanks a lot!
BR.
