Adding a new rule to the event grammar to be able to specify values of additional attributes of symbolic event. The new syntax for event symbolic definition is: event_legacy_symbol: PE_NAME_SYM '/' event_config '/' | PE_NAME_SYM sep_slash_dc event_config: event_config ',' event_term | event_term event_term: PE_NAME '=' PE_NAME | PE_NAME '=' PE_VALUE PE_NAME sep_slash_dc: '/' | ':' | At the moment the config options are hardcoded to be used for legacy symbol events to define several perf_event_attr fields. It is: 'config' to define perf_event_attr::config 'config1' to define perf_event_attr::config1 'config2' to define perf_event_attr::config2 'period' to define perf_event_attr::sample_period Legacy events could be now specified as: cycles/period=100000/ If term is specified without the value assignment, then 1 is assigned by default.
