Will Deacon46fd5c62016-06-27 17:30:13 +0100296 This option enables support by default for event stream generation
297 based on the ARM architected timer. It is used for waking up CPUs
298 executing the wfe instruction at a frequency represented as a
299 power-of-2 divisor of the clock rate. The behaviour can also be
300 overridden on the command line using the
301 clocksource.arm_arch_timer.evtstream parameter.
Will Deacon037f6372013-08-23 15:32:29 +0100302 The main use of the event stream is wfe-based timeouts of userspace
303 locking implementations. It might also be useful for imposing timeout
304 on wfe to safeguard against any programming errors in case an expected
305 event is not generated.
306 This must be disabled for hardware validation purposes to detect any
307 hardware anomalies of missing events.
