Hi David, attached is the IA64 architecture specific code for the ACPI-NUMA infrastructure which is meanwhile present in the 2.5 baseline kernels. It provides the interpreters for the ACPI SLIT (System Locality Information Table) and the SRAT (System Ressource Affinity Table). These build three data structures with the NUMA characteristics of the machine: - node_memblk : memory blocks and the nodes to which they belong, - node_cpuid : hardware CPUID and corresponding node ID, - numa_slit AKA node_distance : distance matrix between nodes. We need these things for both discontigmem and NUMA scheduler setup, it would be great to have it in the baseline kernels. Thanks, Erich
