Right, the RapidIO subsystem itself has had the concept of multiple master ports from the beginning.

I'm not surprised there's new silicon with multiple controllers now. -Matt -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
