Please have a look at

https://wiki.xenproject.org/wiki/Submitting_Xen_Project_Patches

And follow the instructions to submit patches.

Hi,

was that right this time?

It didn't seem to make sense to add this to the patch, so I'm appending the program I used for testing the hypercall patch here just for completeness:

#include <stdio.h>

#include <errno.h>

#include <xenctrl.h>

int main(void) {

xc_interface *xch = xc_interface_open(NULL, NULL, 0);

int ver = xc_version(xch, XENVER_version, NULL);

printf("Xen Version %d.%d\n", ver >> 16, ver & 0xffff);

    int domid = xc_domid(xch);

printf("Xen domain: %d\n", domid);        

    if(domid == -1) {

        printf("errno=%d (%s)\n", errno, xc_strerror(xch, errno));

    }

xc_interface_close(xch);

return 0;

}

Felix
