[Xen-devel] running a task (thread) directly on hardware

[tutu sky <ooohooo_u@xxxxxxxxxxx>]

    Hi,
In linux kernel we can use affinity settings to ask scheduler for directly 
running the special thread on special cpu or taskset for special command, I 
have a question that: is it possible in Xen for having such a mechanism? I mean 
is there any hypercall or something similar (I don't have any idea what can it 
be) for which we can ask it to run a program's thread on the cpu? (maybe by 
activating some interrupts which asks  xen scheduler to stop it's work and 
start running the thread which is called by a hypercall).

if i want ask my question in more general way, is there any way for user space 
programs to directly access xen?
i found a discussion here: 
http://xen-devel.narkive.com/tZaT5OaG/using-xen-s-hypercall-interface which i 
think is near what i search for, but is there any more detail about playing 
with xen hypercall layer?

Thanks in advance.
Cheers.
