158 This option enables support for event stream generation based on
159 the ARM architected timer. It is used for waking up CPUs executing
160 the wfe instruction at a frequency represented as a power-of-2
161 divisor of the clock rate.
162 The main use of the event stream is wfe-based timeouts of userspace
163 locking implementations. It might also be useful for imposing timeout
164 on wfe to safeguard against any programming errors in case an expected
165 event is not generated.
166 This must be disabled for hardware validation purposes to detect any
167 hardware anomalies of missing events.
