  72. This option enables support for event stream generation based on
  73. the ARM architected timer. It is used for waking up CPUs executing
  74. the wfe instruction at a frequency represented as a power-of-2
  75. divisor of the clock rate.
  76. The main use of the event stream is wfe-based timeouts of userspace
  77. locking implementations. It might also be useful for imposing timeout
  78. on wfe to safeguard against any programming errors in case an expected
  79. event is not generated.
  80. This must be disabled for hardware validation purposes to detect any
  81. hardware anomalies of missing events.
