131 | help |
132 | This option enables support for event stream generation based on | |
133 | the ARM architected timer. It is used for waking up CPUs executing | |
134 | the wfe instruction at a frequency represented as a power-of-2 | |
135 | divisor of the clock rate. | |
136 | The main use of the event stream is wfe-based timeouts of userspace | |
137 | locking implementations. It might also be useful for imposing timeout | |
138 | on wfe to safeguard against any programming errors in case an expected | |
139 | event is not generated. | |
140 | This must be disabled for hardware validation purposes to detect any | |
141 | hardware anomalies of missing events. | |
