Abstract
Systems, methods, and apparatuses relating to an instruction that allows a trusted execution environment to react to an asynchronous exit are described. In one embodiment, a hardware processor includes a register comprising a field, that when set, is to enable an architecturally protected execution environment for code in an architecturally protected enclave in memory, a decoder circuit to decode a single instruction comprising an opcode into a decoded instruction, the opcode to indicate an execution circuit is to invoke a handler to handle an asynchronous exit from execution of the code in the architecturally protected enclave and then resume execution of the code in the architecturally protected enclave from where the asynchronous exit occurred, and the execution circuit to respond to the decoded instruction as specified by the opcode.
