Policy Engine(PE) recommendation as sensor.
|
||
|
|
|
||
|
|
The QTI Policy Engine sensor device will register the policy engine
|
||
|
|
recommendation with thermal framework as a sensor. This will enable
|
||
|
|
to provide configuration to mitigate cooling devices when a recommendation
|
||
|
|
is sent from Policy Engine hardware. The recommendations are mitigation
|
||
|
|
levels based on CX operating level.
|
||
|
|
|
||
|
|
There can be multiple Policy Engine hardwares for different rails.
