^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9) Systems employing a Non Uniform Memory Access (NUMA) architecture contain
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) collections of hardware resources including processors, memory, and I/O buses,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) that comprise what is commonly known as a NUMA node.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) Processor accesses to memory within the local NUMA node is generally faster
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) than processor accesses to memory outside of the local NUMA node.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) DT defines interfaces that allow the platform to convey NUMA node
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) topology information to OS.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) For the purpose of identification, each NUMA node is associated with a unique
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) token known as a node id. For the purpose of this binding
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) a node id is a 32-bit integer.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) A device node is associated with a NUMA node by the presence of a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) numa-node-id property which contains the node id of the device.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) Example:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) /* numa node 0 */
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) numa-node-id = <0>;
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) /* numa node 1 */
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) numa-node-id = <1>;

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39) The optional device tree node distance-map describes the relative
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40) distance (memory latency) between all numa nodes.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 41)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 42) - compatible : Should at least contain "numa-distance-map-v1".

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 44) - distance-matrix
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 45) This property defines a matrix to describe the relative distances
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 46) between all numa nodes.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 47) It is represented as a list of node pairs and their relative distance.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 48)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 49) Note:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 50) 1. Each entry represents distance from first node to second node.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 51) The distances are equal in either direction.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 52) 2. The distance from a node to self (local distance) is represented
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 53) with value 10 and all internode distance should be represented with
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 54) a value greater than 10.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 55) 3. distance-matrix should have entries in lexicographical ascending
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 56) order of nodes.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 57) 4. There must be only one device node distance-map which must
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 58) reside in the root node.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 59) 5. If the distance-map node is not present, a default
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 60) distance-matrix is used.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 61)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 62) Example:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 63) 4 nodes connected in mesh/ring topology as below,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 64)

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 74) if relative distance for each hop is 20,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 75) then internode distance would be,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 76) 0 -> 1 = 20
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 77) 1 -> 2 = 20
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 78) 2 -> 3 = 20
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 79) 3 -> 0 = 20
