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