[Xen-devel] Is it possible to make hypercall from user application directly?

[weiming <zephyr.zhao@xxxxxxxxx>]

Hi,

I implemented my own Hypercall in xen.

Now I wish my application under dom0 could talk to Xen via my hypercall.
Currently, I make a stub in dom0's kernel, which works as a proxy to forward the request. So, my application first makes a system call to dom0, which then makes hypercall to xen. 

Is this design necessary? May I call hypercalls from user application under dom0 directly?

Thanks,
Weiming
