Abstract: In one embodiment, a system on chip includes: at least one core; a plurality of intellectual property (IP) agents coupled to the at least one core; a shared power rail to provide an operating voltage to the plurality of IP agents; and a power controller, in response to an indication that the plurality of IP agents are in an idle state and the at least one core is in an active state, to power down the shared power rail while the at least one core remains in the active state. Other embodiments are described and claimed.

Abstract: A dynamic firmware module loader loads one of a plurality of a firmware contexts or modules as needed in a containerized environment for secure isolated execution. The modules, called applets, may be loaded and unloaded in a firmware context. The loader may use a hardware inter process communication channel (IPC) to communicate with the secure engine. The modules may be designed to implement specific features desired by basic input/output system vendors, without the use of a system management mode. Designed modules may provide necessary storage and I/O access driver capabilities to be run in trusted execution environment containers.
