      perf metrics: Don't add all tool events for sharing · 8586d274
      Ian Rogers authored
      Tool events are added to the set of events for parsing so that having a
      tool event in a metric doesn't inhibit event sharing of events between
      metrics.
      
      All tool events were added but this meant unused tool events would be
      counted. Reduce this set of tool events to just those present in the
      overall metric list.

      perf metrics: Support all tool events · 9aa09230
      Ian Rogers authored
      Previously duration_time was hard coded, which was ok until commit
      b03b89b3 ("perf stat: Add user_time and system_time events")
      added additional tool events. Do for all tool events what was previously
      done just for duration_time.

      Revert "perf stat: Support metrics with hybrid events" · 17b3867d
      Ian Rogers authored
      This reverts commit 60344f1a.
      
      Hybrid metrics place a PMU at the end of the parse string. This is also
      where tool events are placed. The behavior of the parse string isn't
      clear and so revert the change for now.

      perf evlist: Clear all_cpus before propagating · 33cd6928
      Ian Rogers authored
      all_cpus is merged into during propagation. Initially all_cpus is set
      from PMU sysfs. perf_evlist__set_maps() will recompute it and change
      evsel->cpus to user_requested_cpus if they are given.
      
      If all_cpus isn't cleared then the union of the user_requested_cpus and
      PMU sysfs values is set to all_cpus, whereas just user_requested_cpus is
      necessary.
      
      To avoid this make all_cpus empty prior to propagation.

      perf cpumap: Switch to using perf_cpu_map API · 0255571a
      Ian Rogers authored
      Switch some raw accesses to the cpu map to using the library API. This
      can help with reference count checking. Some BPF cases switch from index
      to CPU for consistency, this shouldn't matter as the CPU map is full.
