| H A D | associativity.rst | 10 characteristic is presented in terms of NUMA node distance within the Linux kernel.
29 device tree properties are used to determine the NUMA distance between resource groups/domains.
42 Linux kernel computes NUMA distance between two domains by recursively comparing
44 level of the resource group, the kernel doubles the NUMA distance between the
49 Form 2 associativity format adds separate device tree properties representing NUMA node distance
50 thereby making the node distance computation flexible. Form 2 also allows flexible primary
