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