(Well, I've not looked at a numa box, but that's not at issue here.) FWIW, we dump the HWRPB memory table early in the boot process, e.g. memcluster 0, usage 1, start 0, end 192 memcluster 1, usage 0, start 192, end 16267 memcluster 2, usage 1, start 16267, end 16384 where "usage 1" is reserved by the console. r~ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
