If no argument is provided then all metrics with the given name/group are opened Signed-off-by: Ian Rogers Acked-by: Gautam Menghani Signed-off-by: Namhyung Kim --- diff --git a/tools/perf/util/python.c b/tools/perf/util/python.c index 779fe1280a567..fa5e4270d1825 100644 --- a/tools/perf/util/python.c +++ b/tools/perf/util/python.c @@ -2051,7 +2051,7 @@ static PyObject *pyrf__parse_events(PyObject *self, PyObject *args) static PyObject *pyrf__parse_metrics(PyObject *self, PyObject *args) { - const char *input; + const char *input, *pmu = NULL; struct evlist evlist = {}; PyObject *result; PyObject *pcpus = NULL, *pthreads = NULL; @@ -2059,14 +2059,14 @@ static PyObject *pyrf__parse_metrics(PyObject *self, PyObject *args) struct perf_thread_map *threads; int ret; - if (!PyArg_ParseTuple(args, "s|OO", &input, &pcpus, &pthreads)) + if (!PyArg_ParseTuple(args, "s|sOO", &input, &pmu, &pcpus, &pthreads)) return NULL; threads = pthreads ?
