This is a bad assumption IMHO. It pushes policy on to the system designer of a RapidIO network. It is very possible to use multiple controllers as entry points in a single RapidIO network fabric space. The reason one would do this is to provide optimized paths to some endpoints in the system. If possible, there should never be a policy assumption like this in kernel space. It's much better to assume that one may or may not have a unique id space. -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/
