124
125 is equivalent to:
126
127 perf script -f trace:<fields> -f sw:<fields> -f hw:<fields>
128
129 i.e., the specified fields apply to all event types if the type string
130 is not given.
131
132 The arguments are processed in the order received. A later usage can
133 reset a prior request. e.g.:
134
135 -f trace: -f comm,tid,time,sym
136
137 The first -f suppresses trace events (field list is ""), but then the
138 second invocation sets the fields to comm,tid,time,sym. In this case a
139 warning is given to the user:
140
141 "Overriding previous field request for all events."
142
143 Alternativey, consider the order:
144
145 -f comm,tid,time,sym -f trace:
146
147 The first -f sets the fields for all events and the second -f
148 suppresses trace events. The user is given a warning message about
149 the override, and the result of the above is that only S/W and H/W
150 events are displayed with the given fields.
151
152 For the 'wildcard' option if a user selected field is invalid for an
153 event type, a message is displayed to the user that the option is
154 ignored for that type. For example:
155
156 $ perf script -f comm,tid,trace
157 'trace' not valid for hardware events. Ignoring.
158 'trace' not valid for software events. Ignoring.
159
160 Alternatively, if the type is given an invalid field is specified it
161 is an error. For example:
162
163 perf script -v -f sw:comm,tid,trace
164 'trace' not valid for software events.
165
166 At this point usage is displayed, and perf-script exits.
167
168 Finally, a user may not set fields to none for all event types.
169 i.e., -f "" is not allowed.
