295 | This option enables support by default for event stream generation |

| 297 | executing the wfe instruction at a frequency represented as a | |

| 299 | overridden on the command line using the | |
| 300 | clocksource.arm_arch_timer.evtstream parameter. | |

301 | The main use of the event stream is wfe-based timeouts of userspace |

| 304 | event is not generated. | |
