That depends on what you are trying to achieve, and on what you have
implemented and how you have implemented it.

Actually, this is not the first time we tell you this: without you
being specific, we can't possibly help.

In this case, "being specific" would have meant specifying:
 - what is your final end goal

​I think Dario meant why you want to add a hypercall? What is your "final" goal​ to add the hypercall? Probably it is just unnecessary to add a hypercall to achieve your final goal.

​I'm just curious if you could give a self introduction. ;-)​
