config RPC_SEND_STACK_ALLOCA_LIMIT
    int "Size limit to use stack (alloca) on send"
    default 256
    help
        RPC send can be called in multiple threads. When one thread
        is wating response from peer, it is permitted to let another
        thread to send call packet to peer when one thread. In normal
        case, there are no differences due to there is only one
        thread in peer, and all requests are handled one by one.
        However, when peer is busy, it is possible there may exist
        differences, and async message can be faster. So, we can't
        use global memory for input and output parameters.

        When input and output parameter memory size is small, alloca
        will be used, and malloc/free can be saved. When memory size
        is large, malloc/free shall be used to avoid stack overflow.
        Anyway, malloc/free can be non-trivial operation.

config RPC_PACKET_SIZE_MAX
    int "RPC packet max size"
    default 1024
    help
        The maximum of RPC packet size, including RPC call packet, RPC
        response packet and RPC async message packet.

config RPC_EVENT_RANGE_COUNT
    int "RPC event range count"
    default 4
    help
        When RPC daemon received an event from peer, RPC daemon itself
        donesn't know how to do with the event. Application shoule
        register router for specified events, usually send the event
        to desired thread.

        It is tedious to use dynamic memory for the registration. So,
        static memory is used, and this configures the maximum count.

config RPC_DEBUG_NOT_SEND
    bool "not send to peer for all RPC"
    default n
    help
        This is for debug only. When enabled, all RPC packet won't be sent
        to peer. This may be used in platform early debug if peer is not
        ready.
