The usual event descriptions are "event=xxx" or "config=xxx", while the event descriptions of CMN are "type=xxx, eventid=xxx" or more complex. $cat /sys/bus/event_source/devices/arm_cmn_0/events/hnf_cache_fill type=0x5,eventid=0x3 When adding aliases for events described as "event=xxx" or "config=xxx", EventCode or ConfigCode can be used in the JSON files to describe the events. But "eventid=xxx, type=xxx" cannot be supported at present. 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 to supplement "eventid=xxx" and "type=xxx", the 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. EventIdCode and Type are added to the event field, and ConfigCode is moved into the event_field array which can also guarantee its original function.
