132 This option enables support for event stream generation based on
133 the ARM architected timer. It is used for waking up CPUs executing
134 the wfe instruction at a frequency represented as a power-of-2
135 divisor of the clock rate.
136 The main use of the event stream is wfe-based timeouts of userspace
137 locking implementations. It might also be useful for imposing timeout
138 on wfe to safeguard against any programming errors in case an expected
139 event is not generated.
140 This must be disabled for hardware validation purposes to detect any
141 hardware anomalies of missing events.
