117 | help |
118 | This option enables support for event stream generation based on | |
119 | the ARM architected timer. It is used for waking up CPUs executing | |
120 | the wfe instruction at a frequency represented as a power-of-2 | |
121 | divisor of the clock rate. | |
122 | The main use of the event stream is wfe-based timeouts of userspace | |
123 | locking implementations. It might also be useful for imposing timeout | |
124 | on wfe to safeguard against any programming errors in case an expected | |
125 | event is not generated. | |
126 | This must be disabled for hardware validation purposes to detect any | |
127 | hardware anomalies of missing events. | |
