This is on top of Mukesh PVH Dom0 v8 series (as stated on the description), which has the following in hvm_physdev_op: static long hvm_physdev_op(int cmd, XEN_GUEST_HANDLE_PARAM(void) arg) { switch ( cmd ) { default: if ( !is_pvh_vcpu(current) || !is_hardware_domain(current->domain) ) return -ENOSYS; /* fall through */ case PHYSDEVOP_map_pirq: case PHYSDEVOP_unmap_pirq: case PHYSDEVOP_eoi: case PHYSDEVOP_irq_status_query: case PHYSDEVOP_get_free_pirq: return do_physdev_op(cmd, arg); } } Thus allowing PVH Dom0 to use any PHYSDEVOP_* Roger. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
