123 This option enables support for event stream generation based on
124 the ARM architected timer. It is used for waking up CPUs executing
125 the wfe instruction at a frequency represented as a power-of-2
126 divisor of the clock rate.
127 The main use of the event stream is wfe-based timeouts of userspace
128 locking implementations. It might also be useful for imposing timeout
129 on wfe to safeguard against any programming errors in case an expected
130 event is not generated.
131 This must be disabled for hardware validation purposes to detect any
132 hardware anomalies of missing events.
