Fair enough. The method should be a simple wrapper to libtraceevent APIs

The pevent thing is per perf.data file, so I made it stop being static
and become a perf_session member, so tools processing perf.data files
use perf_session and _there_ we read the event into session->pevent and
then have to change everywhere to stop using that single global pevent
variable and use the per session one.
Dmitry, can you test the attached patch to check if it solves the
problems you reported?
This looks good and works for my x86 <-> ARM tests.
Note that it _doesn't_ fall backs to trace__event_id, as we're not
interested at all in what is present in the
/sys/kernel/debug/tracing/events in the workstation doing the analysis,
just in what is in the perf.data file.
Agree.
Dmitry
