- 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.
