[Xen-devel] Using Xen's hypercall interface?

[Rig Gel <rigelras@xxxxxxxxx>]

Hi all,

- I'm sorry if this is a repost, I was informed that this is the correct mailing list only after sending a msg to xen-users -Â

I would like to compile a simple ELF which would make a simple a hypercall from a guest in order to

learn a bit more about the Xen Hypercall interface.

I tried including the hypervisor.h and -I'ing the ./extras/mini-os/ dir but it seems that I'm missing a few flags or paths in order ot make it fully compile correctlyÂ

Can anyone hint or explain a bit what is the appropriate way to link against Xen's header files ?Â

I only need hypervisor.h in order to call some hypercallsÂ

Attached below a sample of my code -

#include <hypervisor.h>

...

snipÂ

...

void test_xen_version(int vers) {

  HYPERVISOR_xen_version(vers);

}

( using the xe_version hypercall is just a mere example, I would like to just know how to link/compile correctly against the required header files/libs )
