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