Abstract
Systems, methods, and apparatuses for implementing device security manager architecture for trusted execution environment input/output (TEE-IO) capable system-on-a-chip integrated devices are described. In one example, a system includes a hardware processor core configurable to implement a trust domain manager to manage one or more virtual machines as a respective trust domain isolated from a virtual machine monitor, and an input/output device coupled to the hardware processor core and comprising a device security manager circuit, wherein the device security manager circuit is to, in response to an trusted request from the trust domain manager to a control interface of the device security manager circuit, access a state of a trusted device interface of the input/output device for a trust domain of the trust domain manager, and provide a corresponding response to the trust domain manager.
