[Xen-devel] How does hypervisor handle the hypercalls from guest OSes?

["K.C. Chiu" <B8844014@xxxxxxxxxxxxxxxxx>]

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
