This means if we trigger + * TB sync from a thread from one subcore, it would affect TB values of + * sibling subcores of the same core. + * + * All threads need to co-ordinate before making opal hmi handler. + * All threads will use sibling_subcore_state->in_guest[] (shared by all + * threads in the core) in paca which holds information about whether + * sibling subcores are in Guest mode or host mode. The in_guest[] array + * is of size MAX_SUBCORE_PER_CORE=4, indexed using subcore id to set/unset + * subcore status. Only primary threads from each subcore is responsible + * to set/unset its designated array element while entering/exiting the + * guset. + * + * After invoking opal hmi handler call, one of the thread (of entire core) + * will need to resync the TB.
