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