Subject: [PATCH 05/19] perf metric: Add macros for iterating map events
Date: Sun, 19 Jul 2020 20:13:06 +0200 [thread overview]
Message-ID: <20200719181320.785305-6-jolsa@kernel.org> (raw)
In-Reply-To: <20200719181320.785305-1-jolsa@kernel.org>
Adding following macros to iterate events and metric:
map_for_each_event(__pe, __idx, __map)
- iterates over all pmu_events_map events
map_for_each_metric(__pe, __idx, __map, __metric)
- iterates over all metrics that match __metric argument
and use it in metricgroup__add_metric function. Macros
will be be used from other places in following changes.
