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.
|
2013-08-23 21:32:29 +07:00
|
|
|
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.
