perf evlist: Introduce perf_evlist__new_dummy constructor

2016-01-07T16:14:56+00:00

For case where all we need is an evlist with just an "dummy" evsel,
like in some 'perf test' entries.

perf evlist: Add perf_evlist__remove()

2015-09-28T20:15:31+00:00

Add a counterpart to perf_evlist__add() that does the opposite and
deletes the evsel.

This will be used by perf inject to remove unwanted evsels.

perf evlist: Add perf_evlist__id2evsel_strict()

2015-09-28T20:11:00+00:00

perf_evlist__id2evsel_strict() is the same as perf_evlist__id2evsel()
except that it ensures that the id must match.

This will be used by perf inject to find a specific evsel that is to be
deleted, hence the need to match exactly.

perf evlist: Fix splice_list_tail() not setting evlist

2015-09-15T13:23:17+00:00

Commit d49e46950772 ("perf evsel: Add a backpointer to the evlist a
evsel is in") updated perf_evlist__add() but not
perf_evlist__splice_list_tail().

This illustrates that it is better if perf_evlist__splice_list_tail()
calls perf_evlist__add() instead of duplicating the logic, so do that.
This will also simplify a subsequent fix for propagating maps.

perf evlist: Add has_user_cpus member

2015-09-15T13:20:50+00:00

Subsequent patches will need to call perf_evlist__propagate_maps without
reference to a "target".  Add evlist->has_user_cpus to record whether
the user has specified which cpus to target (and therefore whether that
list of cpus should override the default settings for a selected event
i.e. the cpu maps should be propagated)

perf evlist: Remove redundant validation from propagate_maps()

2015-09-15T13:16:48+00:00

The validation checks that the values that were just assigned, got
assigned i.e. the error can't ever happen.  Subsequent patches will call
this code in places where errors are not being returned.  Changing those
code paths to return this non-existent error is counter-productive, so
just remove it.

That in turn results in perf_evlist__set_maps not needing to return an
error, but callers aren't checking it either, so remove that too.

perf evlist: Add backpointer for perf_env to evlist

2015-08-28T17:54:14+00:00

Add backpointer to perf_env in evlist, so we can easily access env when
processing something where we have a evsel or evlist.
