A commit baa914cd81f5 ("firewire: add kernel API to access CYCLE_TIME register") allow unit drivers to read CYCLE_TIME of 1394 OHCI controller. The value expresses monotonic time with 42.195 Mhz resolution and wrapping around every 128 seconds. The controller uses the time to govern isochronous cycle.
This commit extends tracepoints event including the value so that event parser can compute gap between current isochronous cycle and the latest isochronous cycle in which packet is processed (in IR context) or scheduled (in IT context). It loses backward compatibility to former format of the tracepoints event.
