969 Allow the use of tracepoints as software performance counters.
970
971 When this is enabled, you can create perf counters based on
972 tracepoints using PERF_TYPE_TRACEPOINT and the tracepoint ID
973 found in debugfs://tracing/events/*/*/id. (The -e/--events
974 option to the perf tool can parse and interpret symbolic
975 tracepoints, in the subsystem:tracepoint_name format.)
