1. A method, comprising:
computing, by a platform management framework driver, a platform electrical power limit as a function of properties of elements presently connected to an electronic device, the platform electrical power limit being a limit on a total electrical power allowed to be consumed by a group of elements in the electronic device at a given time, and the group of elements including the elements presently connected to the electronic device;
providing, by the platform management framework driver, the platform electrical power limit to a platform boost and throttle (PBT) controller;
determining, by the PBT controller, a present platform electrical power consumption; and
adjusting, by the PBT controller, one or more operating parameters for specified elements from among the group of elements to control electrical power consumption by the specified elements based on a relationship between the present platform electrical power consumption and the platform electrical power limit.
