Hi,

Actually, defined by Credit scheduler, each PCPU (physical CPU, if you run Xen on a multi-core machine, you get multiple PCPUs) has its own runqueue, and its own current vcpu as well.

The PCPUs of the system makes their own scheduling decisions independently.

Best,

主题： [Xen-devel] Question about the current vcpu.

Hi all,

There is a macro current which may mean to get the current vcpu information.

But the physical machine may be multi-core ,thus there may be two or more vcpus running in parallel on different cores.Then which vcpu is the current? How should I understand the current vcpu please?

Thanks.

Cheer,
