96 | help |
97 | This option enables support for event stream generation based on | |
98 | the ARM architected timer. It is used for waking up CPUs executing | |
99 | the wfe instruction at a frequency represented as a power-of-2 | |
100 | divisor of the clock rate. | |
101 | The main use of the event stream is wfe-based timeouts of userspace | |
102 | locking implementations. It might also be useful for imposing timeout | |
103 | on wfe to safeguard against any programming errors in case an expected | |
104 | event is not generated. | |
105 | This must be disabled for hardware validation purposes to detect any | |
106 | hardware anomalies of missing events. | |
