- 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.
