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. |
