Hi All !!
I'm trying to encapsulate some operations into
"hypercall" and pass the hypercall into hypervisor.
But I cannot find out how the hypervisor to deal with
hypercalls from guest OSes.
I find a function "do_dom0_op" in
xeno-1.2.bk/xen/common/dom0_ops.c.
It looks like the function which would deal with
hypercalls .
and I try to modify the code in do_dom0_op to handle my
new hypercall, but I failed.
can someone tell me how does hypervisor handle the
hypercalls from guest OSes?
Cheers
