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.
