Hello.

Do I understand it right that there's no dedicated mechanism
other than icount that would switch current CPU in emulated
SMP system and that in the absence of icount such scheduling
is a side effect of interrupt delivery to the current CPU?


In case I start two CPUs and execute a while (1) loop in both of them with interrupts disabled. Will Qemu ever switch from one CPU to the other?
