perf tools: Add config options support for event parsing
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.
