| help |
| The devfreq-event device provide the raw data and events which |
| indicate the current state of devfreq-event device. The provided |
| data from devfreq-event device is used to monitor the state of |
| device and determine the suitable size of resource to reduce the |
| wasted resource. |
| |
| The devfreq-event device can support the various type of events |
| (e.g., raw data, utilization, latency, bandwidth). The events |
| may be used by devfreq governor and other subsystem. |
