308 based on the ARM architected timer. It is used for waking up CPUs
309 executing the wfe instruction at a frequency represented as a
310 power-of-2 divisor of the clock rate. The behaviour can also be
311 overridden on the command line using the
312 clocksource.arm_arch_timer.evtstream parameter.
Will Deacon037f6372013-08-23 15:32:29 +0100313 The main use of the event stream is wfe-based timeouts of userspace
314 locking implementations. It might also be useful for imposing timeout
315 on wfe to safeguard against any programming errors in case an expected
316 event is not generated.
317 This must be disabled for hardware validation purposes to detect any
318 hardware anomalies of missing events.
