OPTIONS
-------
-None
+
+Without options all known events will be listed.
+
+To limit the list use:
+
+. 'hw' or 'hardware' to list hardware events such as cache-misses, etc.
+
+. 'sw' or 'software' to list software events such as context switches, etc.
+
+. 'cache' or 'hwcache' to list hardware cache events such as L1-dcache-loads, etc.
+
+. 'tracepoint' to list all tracepoint events, alternatively use
+ 'subsys_glob:event_glob' to filter by tracepoint subsystems such as sched,
+ block, etc.
+
+. If none of the above is matched, it will apply the supplied glob to all
+ events, printing the ones that match.
+
+One or more types can be used at the same time, listing the events for the
+types specified.
