Will Deacon46fd5c62016-06-27 17:30:13 +0100321 This option enables support by default for event stream generation
322 based on the ARM architected timer. It is used for waking up CPUs
323 executing the wfe instruction at a frequency represented as a
324 power-of-2 divisor of the clock rate. The behaviour can also be
325 overridden on the command line using the
326 clocksource.arm_arch_timer.evtstream parameter.
Will Deacon037f6372013-08-23 15:32:29 +0100327 The main use of the event stream is wfe-based timeouts of userspace
328 locking implementations. It might also be useful for imposing timeout
329 on wfe to safeguard against any programming errors in case an expected
330 event is not generated.
331 This must be disabled for hardware validation purposes to detect any
332 hardware anomalies of missing events.
