Abstract | Systems, methods, and apparatuses for implementing input/output extensions for trust domains are described. In one example, a hardware processor includes a hardware processor core comprising a trust domain manager to manage one or more hardware isolated virtual machines as a respective trust domain with a region of protected memory, and input/output memory management unit (IOMMU) circuitry coupled between the hardware processor core and an input/output device, wherein the IOMMU circuitry is to, for a request from the input/output device for a direct memory access of a protected memory of a trust domain, allow the direct memory access in response to a field in the request being set to indicate the input/output device is in a trusted computing base of the trust domain. |
