ok first try ;) description + grammar attached
- event has a general format:
pmu/event_def[:modifier] [ ',' pmu/event_def[:modifier] ] ...
where event_def depends on the chosen pmu:
'cpu' 'tracepoint' 'breakpoint'
- to keep some of the old interface, symbolic and cache events stays,
since they are recognizable by keywords (event_symbol, event_cache)
- raw events are defined with the help of event keywords like:
cpu/raw,config=1,config1=0,config2=0
cpu/hw,config=1,config1=0
* first symbol after '/' defines the type: raw/hw/cache
which match PERF_TYPE_RAW/PERF_TYPE_HARDWARE/PERF_TYPE_HW_CACHE
* the rest consists assignments for 'config/config1/config1' keywords
that match with the perf_event_attr:config/config1/config values
(possibly extended once we have sysfs events representation)
- tracepoint events are defined like:
tracepoint/system:tracepoint
where tracepoint could contain '*?'
- breakpoint events are defined like:
breakpoint/addr:type
- each event could be followed by modifier definition
- I think pmu names should match registered pmu names,
but we could make some shortcuts so we dont need to type 'tracepoint/',
but just 'tp/' or smth..
- as for tracepoints it looks like the old format does not clash with the new one
and we could add shortcut (omit the 'tracepoint/') like:
event: event_tracepoint
- not sure I should include 'software' pmu, as it seems to covered by
event_symbol events
thanks for comments,
jirka
