The behaviour can also be overridden on the command line using the - clocksource.arm_arch_timer.evtstream parameter. + clocksource.arm_arch_timer.evtstrm 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
