Specify tracing options.
|
|
|
|
``[enable=]PATTERN``
|
|
|
|
Immediately enable events matching *PATTERN*
|
|
(either event name or a globbing pattern). This option is only
|
|
available if QEMU has been compiled with the ``simple``, ``log``
|
|
or ``ftrace`` tracing backend. To specify multiple events or patterns,
|
|
specify the :option:`-trace` option multiple times.
|
|
|
|
Use :option:`-trace help` to print a list of names of trace points.
|
|
|
|
``events=FILE``
|
|
|
|
Immediately enable events listed in *FILE*.
|
|
The file must contain one event name (as listed in the ``trace-events-all``
|
|
file) per line; globbing patterns are accepted too. This option is only
|
|
available if QEMU has been compiled with the ``simple``, ``log`` or
|
|
``ftrace`` tracing backend.
|
|
|
|
``file=FILE``
|
|
|
|
Log output traces to *FILE*.
|
|
This option is only available if QEMU has been compiled with
|
|
the ``simple`` tracing backend.
