|
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. |
