is equivalent to:
perf script -f trace:<fields> -f sw:<fields> -f hw:<fields>
-
+
i.e., the specified fields apply to all event types if the type string
is not given.
-
+
The arguments are processed in the order received. A later usage can
reset a prior request. e.g.:
-
+
-f trace: -f comm,tid,time,ip,sym
-
+
The first -f suppresses trace events (field list is ""), but then the
second invocation sets the fields to comm,tid,time,ip,sym. In this case a
warning is given to the user:
-
+
"Overriding previous field request for all events."
-
+
Alternatively, consider the order:
-
+
-f comm,tid,time,ip,sym -f trace:
-
+
The first -f sets the fields for all events and the second -f
suppresses trace events. The user is given a warning message about
the override, and the result of the above is that only S/W and H/W
events are displayed with the given fields.
-
+
For the 'wildcard' option if a user selected field is invalid for an
event type, a message is displayed to the user that the option is
ignored for that type. For example:
-
+
$ perf script -f comm,tid,trace
'trace' not valid for hardware events. Ignoring.
'trace' not valid for software events. Ignoring.
-
+
Alternatively, if the type is given an invalid field is specified it
is an error. For example:
-
+
perf script -v -f sw:comm,tid,trace
'trace' not valid for software events.
-
+
At this point usage is displayed, and perf-script exits.
-
+
Finally, a user may not set fields to none for all event types.
i.e., -f "" is not allowed.
