bool "Enable ARM architected timer event stream generation by default"
default y if ARM_ARCH_TIMER

help
This option enables support by default for event stream generation
based on the ARM architected timer. It is used for waking up CPUs
executing the wfe instruction at a frequency represented as a
power-of-2 divisor of the clock rate. The behaviour can also be
overridden on the command line using the
clocksource.arm_arch_timer.evtstream parameter.
The main use of the event stream is wfe-based timeouts of userspace
locking implementations. It might also be useful for imposing timeout
on wfe to safeguard against any programming errors in case an expected
event is not generated.
This must be disabled for hardware validation purposes to detect any
hardware anomalies of missing events.
