      perf evsel: Refactor tool events · 6828d692
      Ian Rogers authored
      Tool events unnecessarily open a dummy perf event which is useless
      even with `perf record` which will still open a dummy event. Change
      the behavior of tool events so:
      
       - duration_time - call `rdclock` on open and then report the count as
         a delta since the start in evsel__read_counter. This moves code out
         of builtin-stat making it more general purpose.
      
       - user_time/system_time - open the fd as either `/proc/pid/stat` or
         `/proc/stat` for cases like system wide. evsel__read_counter will
         read the appropriate field out of the procfs file. These values
         were previously supplied by wait4, if the procfs read fails then
         the wait4 values are used, assuming the process/thread terminated.
         By reading user_time and system_time this way, interval mode, per
         PID and per CPU can be supported although there are restrictions
         given what the files provide (e.g. per PID can't be combined with
         per CPU).
      
      Opening any of the tool events for `perf record` is changed to return
      invalid.

      perf: parse-events: Fix compilation error while defining DEBUG_PARSER · 9aa61d8e
