|
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.
