326 overridden on the command line using the
327 clocksource.arm_arch_timer.evtstream parameter.
Will Deacon037f6372013-08-23 15:32:29 +0100[diff] [blame]328 The main use of the event stream is wfe-based timeouts of userspace
329 locking implementations. It might also be useful for imposing timeout
330 on wfe to safeguard against any programming errors in case an expected
331 event is not generated.
332 This must be disabled for hardware validation purposes to detect any
333 hardware anomalies of missing events.
