296 based on the ARM architected timer. It is used for waking up CPUs
297 executing the wfe instruction at a frequency represented as a
298 power-of-2 divisor of the clock rate. The behaviour can also be
299 overridden on the command line using the
300 clocksource.arm_arch_timer.evtstream parameter.
Will Deacon037f6372013-08-23 15:32:29 +0100[diff] [blame]301 The main use of the event stream is wfe-based timeouts of userspace
302 locking implementations. It might also be useful for imposing timeout
303 on wfe to safeguard against any programming errors in case an expected
304 event is not generated.
305 This must be disabled for hardware validation purposes to detect any
306 hardware anomalies of missing events.
