    perf tools: Improve support for sessions with multiple events · e248de33
    Arnaldo Carvalho de Melo authored
    By creating an perf_evlist out of the attributes in the perf.data file
    header, so that we can use evlists and evsels when reading recorded
    sessions in addition to when we record sessions.
    More work is needed to allow tools to allow the user to select which
    events are wanted when browsing sessions, be it just one or a subset of
    them, aggregated or showed at the same time but with different
    indications on the UI to allow seeing workloads thru different views at
    the same time.
    But the overall goal/trend is to more uniformly use evsels and evlists.
