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