10.101 SEV

Set Event.

Syntax

SEV{cond}
where:
cond
is an optional condition code.

Operation

This is a hint instruction. It is optional whether it is implemented or not. If it is not implemented, it executes as a NOP. The assembler produces a diagnostic message if the instruction executes as a NOP on the target.
SEV executes as a NOP instruction in ARMv6T2.
SEV causes an event to be signaled to all cores within a multiprocessor system. If SEV is implemented, WFE must also be implemented.

Architectures

This ARM instruction is available in ARMv6K and above.
This 32-bit Thumb instruction is available in ARMv6T2 and above.
This 16-bit Thumb instruction is available in ARMv6T2 and above.
