For CMN neither of these may be present, as an event is typically "type=xx,eventid=xxx". If EventCode and ConfigCode is not added in the alias JSON file, the event description will add "event=0" by default. So, even if the event field is added "eventid=xxx" and "type=xxx", the CMN events final parsing result will be "event=0, eventid=xxx, type=xxx". Therefore, when EventCode and ConfigCode are missing in JSON, "event=0" is no longer added by default. And add EventIdCode and Type to the event field. I compared pmu_event.c before and after compiling with JEVENT_ARCH=all, they are consistent.
