Abstract
Techniques are disclosed relating to performing remote cache invalidations. In some embodiments, primary processor circuitry is configured to, based on execution of a remote invalidate instruction (e.g., an ISA-defined instruction), send a cache invalidate command to coprocessor circuitry. The coprocessor circuitry includes coprocessor cache circuitry and cache invalidation control circuitry configured to, in response to the cache invalidate command sent by the primary processor, invalidate one or more cache lines in the coprocessor cache circuitry without executing any instructions on the coprocessor circuitry.
