      perf data: Add tracepoint events fields CTF conversion support · 69364727
      Sebastian Andrzej Siewior authored
      Adding support to convert tracepoint event fields into CTF
      event fields.
      
      We parse each tracepoint event for CTF conversion and add
      tracepoint fields as regular CTF event fields, so they
      appear in babeltrace output like:
      
        $ babeltrace ./ctf-data/
        ...
        [09:02:00.950703057] (+?.?????????) sched:sched_stat_runtime: { }, { perf_ip = ... SNIP ... common_type = 298, common_flags = 1, \
        common_preempt_count = 0, common_pid = 31813, comm = "perf", pid = 31813, runtime = 458800, vruntime = 52059858071 }

      Current perf kmem fails when -v option is used.  As it's very useful for
      debugging, let's allow it.

      perf kmem: Fix segfault when invalid sort key is given · 405f8755

      When it tries to free 'str', it was already updated by strsep() - so it
      needs to save the original pointer.

      perf stat: Always correctly indent ratio column · 79103528
      Andi Kleen authored
      When cycles or instructions do not print anything, as in being,
      --per-socket or --per-core modi, the ratio column was not correctly
      indented for them. This lead to some ratios not lining up with the
      others. Always indent correctly when nothing is printed.

      perf stat didn't compute the IPC and other formulas for individual CPUs
      with -A. Fix this for the easy -A case. As before, --per-core and
      --per-socket do not handle it, they simply print nothing.
