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