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