+         When this is enabled, you can create perf counters based on
+         tracepoints using PERF_TYPE_TRACEPOINT and the tracepoint ID
+         found in debugfs://tracing/events/*/*/id. (The -e/--events
+         option to the perf tool can parse and interpret symbolic
+         tracepoints, in the subsystem:tracepoint_name format.)
