| 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. | |
