Abstract: Techniques are disclosed relating to performing remote invalidation of memory access permission information. In some embodiments, primary processor circuitry is configured to, based on execution of a remote permission table invalidate instruction (e.g., an ISA-defined instruction), send a remote invalidate command to secondary processor circuitry. The secondary processor circuitry includes secondary processor permission circuitry and is configured to, in response to the remote invalidate command sent by the primary processor, invalidate one or more entries in the secondary processor permission circuitry. In some embodiments, the secondary processor performs the invalidate without executing any instructions on the secondary processor circuitry.
