In my understanding , from drivers/acpi/numa.c, a node is created by a pxm found in SRAT table at boot time. the node-number for the pxm which was not found in SRAT at boot time is "-1". please check how acpi_map_pxm_to_node() is used. If pci's node-id is based on pxm, checking return vaule of pxm_to_node() will be good. -Kame - 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/ | ||||||||||||
