Abstract

Techniques and mechanisms for a processor core to execute an instruction for a hardware (HW) thread to have access to a trusted execution environment (TEE). In an embodiment, execution of the instruction includes determining whether any sibling HW thread, which is currently active, is also currently approved to access the TEE. TEE access by the HW thread is conditioned upon a requirement that any sibling HW thread is either currently inactive, is currently in the same TEE, or is currently approved to enter the TEE. In another embodiment, execution of another instruction, for the HW thread to exit the TEE, includes or otherwise results in system software being conditionally notified of an opportunity to wake up one or more sibling HW threads.
