[Qemu-devel] Round robin of multi-vcpu in qemu

Hi there: I'm studying the execution details of multi-vcpu in TCG mode. The vcpus in TCG mode are executed one by one in a sequencial way. I read the function [tcg_exec_all] in Qemu 1.3.0 as bellow, but the implementation is not as I expected. [tcg_exec_all] will finally call [cpu_exec] to
