315 | This option enables support by default for event stream generation |
316 | based on the ARM architected timer. It is used for waking up CPUs | |
317 | executing the wfe instruction at a frequency represented as a | |
318 | power-of-2 divisor of the clock rate. The behaviour can also be | |
319 | overridden on the command line using the | |

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