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.) | ||
