Re: [Xen-devel] Xen with dom0 pvops on ultra-recent "git tip" kernel on

Hello,

The native Xen kernel has an arch/x86/kernel/ioport-xen.c which calls:

        HYPERVISOR_physdev_op(PHYSDEVOP_set_iobitmap, &set_iobitmap);

Is this a feature mabye still missing from the paravirtualized Xen?

If yes, what would it take?  A new paravirt call?

Thanks,
        Christophe
