WD		 189 help
190 This option enables support for event stream generation based on
191 the ARM architected timer. It is used for waking up CPUs executing
192 the wfe instruction at a frequency represented as a power-of-2
193 divisor of the clock rate.
194 The main use of the event stream is wfe-based timeouts of userspace
195 locking implementations. It might also be useful for imposing timeout
196 on wfe to safeguard against any programming errors in case an expected
197 event is not generated.
198 This must be disabled for hardware validation purposes to detect any
199 hardware anomalies of missing events.
