335 based on the ARM architected timer. It is used for waking up CPUs
336 executing the wfe instruction at a frequency represented as a
337 power-of-2 divisor of the clock rate. The behaviour can also be
338 overridden on the command line using the
339 clocksource.arm_arch_timer.evtstream parameter.
Will Deacon037f6372013-08-23 15:32:29 +0100[diff] [blame]340 The main use of the event stream is wfe-based timeouts of userspace
341 locking implementations. It might also be useful for imposing timeout
342 on wfe to safeguard against any programming errors in case an expected
343 event is not generated.
344 This must be disabled for hardware validation purposes to detect any
345 hardware anomalies of missing events.
