312 overridden on the command line using the
313 clocksource.arm_arch_timer.evtstream parameter.
Will Deacon037f6372013-08-23 15:32:29 +0100[diff] [blame]314 The main use of the event stream is wfe-based timeouts of userspace
315 locking implementations. It might also be useful for imposing timeout
316 on wfe to safeguard against any programming errors in case an expected
317 event is not generated.
318 This must be disabled for hardware validation purposes to detect any
319 hardware anomalies of missing events.
