Stephane reported that we don't set properly PERIOD sample type for
events with period term defined.
Before:
$ perf record -e cpu/cpu-cycles,period=1000/u ls
$ perf evlist -v
cpu/cpu-cycles,period=1000/u: ... sample_type: IP|TID|TIME|PERIOD, ...
After:
$ perf record -e cpu/cpu-cycles,period=1000/u ls
$ perf evlist -v
cpu/cpu-cycles,period=1000/u: ... sample_type: IP|TID|TIME, ...
Setting PERIOD sample type based on period term setup.
Committer note:
When we use -c or a period=N term in the event definition, then we don't
need to ask the kernel, for this event, via perf_event_attr.sample_type
|= PERF_SAMPLE_PERIOD, to put the event period in each sample for this
event, as we know it already, it is in perf_event_attr.sample_period.
