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