This option enables support 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 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.
