[Xen-devel] Can Xen sleep or wake up a thread?

[Xinxin Jin <xinxinjin89@xxxxxxxxx>]

Hi everyone,

I found in Xen, when synchronization between multiple threads is needed, Xen always uses busy wait or simple spin lock. In linux, the kernel can block a waiting thread and schedule other threads for execution. Why does Xen do not have this mechanism? I guess it is because the performance issue? A lot of appreciation for your answer !!

Xinxin
