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