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: Various techniques for enabling the control and monitoring of a USB device mode controller to a USB-C connector, for the performance of a USB device mode data connection, are disclosed herein. In an example, a computing system that includes multiple USB-C connectors but a single USB device mode controller may manage the availability of the controller to a particular connector. The computing system may determine availability of a USB device mode controller to control the first USB-C connector, wherein the attempted data connection occurs with the first USB-C connector configured as an upstream facing port. The computing system may further perform, in response, a data role swap of the first USB-C connector to configure the first USB-C connector as a downstream facing port. The computing system may, further continue the attempted data connection with the remote computing system via the first USB-C connector configured as a downstream facing port.

Abstract: Various techniques for enabling the control and monitoring of a USB device mode controller to a USB-C connector, for the performance of a USB device mode data connection, are disclosed herein. In an example, a computing system that includes multiple USB-C connectors but a single USB device mode controller may manage the mapping of the controller to a particular connector, through operations that identify the mapping and the characteristics of the connector, process a request to change the mapping of the device mode controller, and perform the change to the mapping of the device mode controller. Such a change may include a disconnection or reassignment of a particular USB-C connector to the controller. Further examples to determine the availability of a USB device mode controller, and respond to a scenario where the USB device mode controller is not available, are also disclosed.
