93 This option enables support for event stream generation based on
94 the ARM architected timer. It is used for waking up CPUs executing
95 the wfe instruction at a frequency represented as a power-of-2
96 divisor of the clock rate.
97 The main use of the event stream is wfe-based timeouts of userspace
98 locking implementations. It might also be useful for imposing timeout
99 on wfe to safeguard against any programming errors in case an expected
100 event is not generated.
101 This must be disabled for hardware validation purposes to detect any
102 hardware anomalies of missing events.

132 for all devicetree enabled platforms. This driver will be
