AMD PMF Driver (a.k.a Platform Management Framework) provides a
centralized framework based on sensor inputs, OS hints, platform state
and APU metrics to dynamically manage perf, power and system thermals.
The goal of the driver is to enhance end user experience by making AMD
PCs smarter, quieter, power efficient by adapting to user behavior and
environment.
The larger goals include:
- Enable easy customization of smart PC solutions by OEMs.
- Provide a framework for OEMs to add in custom algorithms and solutions
- Improve standby and dynamic platform power through active power
management of platform devices.
In this series, support for following features has been added.
- "Static Power Slider" meant to manage the power budget based on the
power modes or the slider position.
- "Auto Mode" tracks the moving power average of the APU and takes
intelligent decisions to switch between different modes.
- "Cool n Quiet Framework (CnQF)" is an extension to the static slider,
where the system power can be boosted or throttled independent
of the selected slider position.
