| help |
| This option enables support for event stream generation based on |
| the ARM architected timer. It is used for waking up CPUs executing |
| the wfe instruction at a frequency represented as a power-of-2 |
| divisor of the clock rate. |
| The main use of the event stream is wfe-based timeouts of userspace |
| locking implementations. It might also be useful for imposing timeout |
| on wfe to safeguard against any programming errors in case an expected |
| event is not generated. |
| This must be disabled for hardware validation purposes to detect any |
| hardware anomalies of missing events. |
