| D | numa.txt | 36 3 - distance-map
39 The optional device tree node distance-map describes the relative
40 distance (memory latency) between all numa nodes.
42 - compatible : Should at least contain "numa-distance-map-v1".
44 - distance-matrix
47 It is represented as a list of node pairs and their relative distance.
50 1. Each entry represents distance from first node to second node.
52 2. The distance from a node to self (local distance) is represented
53 with value 10 and all internode distance should be represented with
55 3. distance-matrix should have entries in lexicographical ascending

29 device tree properties are used to determine the NUMA distance between resource groups/domains.
