GETSECWAKEUP

The GETSEC[WAKEUP] instruction wakes up the processor from a low-power state or triggers a specific security-related wake event, depending on the processor implementation.

The following table covers what the source and destinations can be.

DO NOT support LOCK

This instruction is only available when the processor is operating in 64-bit mode. Execution in compatibility mode or 32-bit mode SHALL result in an invalid opcode exception.

The instruction is designed for use in specific security contexts; executing this instruction without the appropriate hardware support or in an incorrect power state MAY result in an ignored operation or a general protection fault (#GP) depending on the CPU stepping. Ensure that the processor supports the GETSEC feature flag in CPUID before execution to avoid undefined behavior.
