Abstract: One embodiment provides an apparatus. The apparatus includes an input output memory management unit (I/O MMU), a non-secure operating system (OS) driver, a secure OS driver and a virtual machine monitor (VMM). The I/OMMU is to couple an I/O Controller to a memory. The I/O Controller is coupled to a secure device and a non-secure device and has one I/O Controller identifier. The non-secure OS driver is associated with the non-secure device. The secure OS driver is associated with the secure device. The VMM is to allocate a secure address space to a secure OS and a non-secure address space to a non-secure OS. The secure address space is non-overlapping with the non-secure address space.

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.

Abstract: Particular embodiments described herein provide for an electronic device that can receive data from an operating system in an electronic device, where the data is related to hardware that is in communication with the electronic device through a multimodal interface and communicate the data and/or related data to a local policy manager, where the local policy manager is in communication with the multimodal interface. The multimodal interface can be configured to support power transfers, directionality, and multiple input/output (I/O) protocols on the same interface.
