xen/events: support threaded irqs for interdomain event channels
Export bind_interdomain_evtchn_to_irq() so drivers can use threaded interrupt handlers with: irq = bind_interdomain_evtchn_to_irq(remote_dom, remote_port); if (irq < 0) /* error */ ret = request_threaded_irq(...); Signed-off-by: Juergen Gross <jgross@suse.com> Acked-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> Signed-off-by: David Vrabel <david.vrabel@citrix.com>
