Abstract: Embodiments of exitless guest to host (G2H) notification are described. In some embodiments, G2H is provided via an instruction. An exemplary processor includes decoder circuitry to decode a single instruction, the single instruction to include a field for an opcode; and execution processing resources to execute the decoded single instruction according to the at least the opcode to cause an exitless guest to host notification from a virtual processor to a physical or virtual processor.
