Over there I only see this function for kcbind?

+/* specify kernel consumer */
+static __inline int time_pps_kcbind(pps_handle_t handle,
+				    const int kernel_consumer,
+				    const int edge, const int tsformat)
+{
+	int error;
+	struct pps_bind_args arg;
+
+	arg.tsformat = tsformat;
+	arg.edge = edge;
+	arg.consumer = kernel_consumer;
+	error = ioctl(handle, PPS_IOC_KC_BIND, &arg);
+	return(error);
+}


And of course the function in serial.c dat mentions KC_BIND.
Is that right?

Could we cook up a patch to LinuxPPS just for fun?
