H A Dassociativity.rst10 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
51 domain numbering. With numa distance computation now detached from the index value in
61 used as an index while computing numa distance information via "ibm,numa-distance-table".
68 computing the distance of domain 8 from other domains present in the system. For the rest of
69 this document, this offset will be referred to as domain distance offset.
