   2 Specify tracing options.
   3
   4 .. option:: [enable=]PATTERN
   5
   6   Immediately enable events matching *PATTERN*
   7   (either event name or a globbing pattern).  This option is only
   8   available if QEMU has been compiled with the ``simple``, ``log``
   9   or ``ftrace`` tracing backend.  To specify multiple events or patterns,
  10   specify the :option:`-trace` option multiple times.
  11
  12   Use :option:`-trace help` to print a list of names of trace points.
  13
  14 .. option:: events=FILE
  15
  16   Immediately enable events listed in *FILE*.
  17   The file must contain one event name (as listed in the ``trace-events-all``
  18   file) per line; globbing patterns are accepted too.  This option is only
  19   available if QEMU has been compiled with the ``simple``, ``log`` or
  20   ``ftrace`` tracing backend.
  21
  22 .. option:: file=FILE
  23
  24   Log output traces to *FILE*.
  25   This option is only available if QEMU has been compiled with
  26   the ``simple`` tracing backend.
