Hi Ingo, Peter et al,
Trying to simplify using the API for tools and more specifically for
'perf test' regression tests, please take a look, perhaps starting from the last
changeset, that implements a regression test using the resulting library API.
It also reduces the 'perf' tool footprint by not using hard coded array
sizes, more need to be done, but should be a good start, one changeset shows a
good reduction in BSS use.
Suggestions for naming most welcome, I thought about using "event__",
but that is taken, "perf_event__", but thought it would clash with "event_t",
so used the jargon used for the '-e' parameters: "Event Selector", but don't
like it that much, what do you think?
Writing the first regression test I think there are more ways to simplify,
on top of these, like not requiring a thread_map, i.e. passing NULL for that
parameter would mean: self-monitor, etc.
If you are pleased as-is, please pull from:
