Smart PC Solutions Builder allows for OEM to define a large number of custom system states to dynamically switch to. The system states are referred to as policies, and multiple policies can be loaded onto the system at any given time, however only one policy can be active at a given time. Policy is a combination of PMF input and output capabilities. The inputs are the incoming information from the other kernel subsystems like LID state, Sensor info, GPU info etc and the actions are the updating the power limits of SMU etc. The policy binary is signed and encrypted by a special key from AMD. This policy binary shall have the inputs and outputs which the OEMs can build for the platform customization that can enhance the user experience and system behavior. This series adds the initial support for Smart PC solution to PMF driver. Note that, on platforms where CnQF and Smart PC is advertised, Smart PC shall have higher precedence and same applies for Auto Mode.
