169 This option enables support for event stream generation based on
170 the ARM architected timer. It is used for waking up CPUs executing
171 the wfe instruction at a frequency represented as a power-of-2
172 divisor of the clock rate.
173 The main use of the event stream is wfe-based timeouts of userspace
174 locking implementations. It might also be useful for imposing timeout
175 on wfe to safeguard against any programming errors in case an expected
176 event is not generated.
177 This must be disabled for hardware validation purposes to detect any
178 hardware anomalies of missing events.
