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