3 | help | |
4 | The devfreq-event device provide the raw data and events which | |
5 | indicate the current state of devfreq-event device. The provided | |
6 | data from devfreq-event device is used to monitor the state of | |
7 | device and determine the suitable size of resource to reduce the | |
8 | wasted resource. | |
9 | ||
10 | The devfreq-event device can support the various type of events | |
11 | (e.g., raw data, utilization, latency, bandwidth). The events | |
12 | may be used by devfreq governor and other subsystem. | |
