2 | * builtin-trace.c | |
3 | * | |
4 | * Builtin 'trace' command: | |
5 | * | |
6 | * Display a continuously updated trace of any workload, CPU, specific PID, | |
7 | * system wide, etc. Default format is loosely strace like, but any other | |
8 | * event may be specified using --event. | |

12 | * Initially based on the 'trace' prototype by Thomas Gleixner: | |
