@table @option
@item [enable=]@var{pattern}
Immediately enable events matching @var{pattern}.
The file must contain one event name (as listed in the @file{trace-events-all}
file) per line; globbing patterns are accepted too. This option is only
available if QEMU has been compiled with the @var{simple}, @var{stderr}
or @var{ftrace} tracing backend. To specify multiple events or patterns,
specify the @option{-trace} option multiple times.
Use @code{-trace help} to print a list of names of trace points.

@item file=@var{file}
