1. A processor comprising:
attestation circuitry to determine whether a compute resource of an offload device connected to the processor by an interconnect is trusted; and
secure arbitration mode (SEAM) arbitration circuitry to:
receive an instruction to form a trusted domain for a virtual machine that includes the compute resource of the offload device; and
provision the trusted domain for the virtual machine that includes the processor and the compute resource.
