342 based on the ARM architected timer. It is used for waking up CPUs
343 executing the wfe instruction at a frequency represented as a
344 power-of-2 divisor of the clock rate. The behaviour can also be
345 overridden on the command line using the
346 clocksource.arm_arch_timer.evtstream parameter.
Will Deacon037f6372013-08-23 15:32:29 +0100[diff] [blame]347 The main use of the event stream is wfe-based timeouts of userspace
348 locking implementations. It might also be useful for imposing timeout
349 on wfe to safeguard against any programming errors in case an expected
350 event is not generated.
351 This must be disabled for hardware validation purposes to detect any
352 hardware anomalies of missing events.
