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