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.) | ||
