1. An apparatus comprising:
a motherboard comprising:
a functional processing core configured to perform a functionality having a Functional Safety (FuSa) level;
a FuSa transceiver configured to communicate with an external safety-island processor, which is external to the motherboard; and
a FuSa controller configured to establish a FuSa connection with the external safety-island processor according to the FuSa level, to send FuSa information corresponding to the functionality of the functional processing core to the external safety-island processor via the FuSa transceiver, and to control one or more FuSa operations of the functional processing core based on one or more control messages received from the external safety-island processor via the FuSa transceiver, wherein the FuSa controller is configured to process FuSa capability information in a message from a discovered external safety-island processor, the FuSa capability information to indicate a FuSa capability of the discovered external safety-island processor, wherein the FuSa controller is configured to select whether to establish the FuSa connection with the discovered external safety-island processor based on the FuSa capability information.
