Thread-topic: [PATCH][RESEND] Bind different tasks' evtchns to different vcpus of Dom0
Currently, all event channels notify Dom0's vcpu0 -- this is not nice
considering scalability.
The patch tries to bind different tasks' evtchns to different vcpus of
Dom0 when the bindings are initialized, and it can also dynamically
change the binding if a task actually gets run on another vcpu for some
reason.
Tests (Inb and OLTP) show the patch can improve scalability to some
notable degree.
