5 Associativity represents the groupings of the various platform resources into
6 domains of substantially similar mean performance relative to resources outside
7 of that domain. Resources subsets of a given domain that exhibit better
9 are represented as being members of a sub-grouping domain. This performance
10 characteristic is presented in terms of NUMA node distance within the Linux kernel.
13 PAPR interface currently supports different ways of communicating these resource
17 Hypervisor indicates the type/form of associativity used via "ibm,architecture-vec-5 property".
18 Bit 0 of byte 5 in the "ibm,architecture-vec-5" property indicates usage of Form 0 or Form 1.
19 A value of 1 indicates the usage of Form 1 associativity. For Form 2 associativity
20 bit 2 of byte 5 in the "ibm,architecture-vec-5" property is used.
28 With Form 1 a combination of ibm,associativity-reference-points, and ibm,associativity
31 The “ibm,associativity” property contains a list of one or more numbers (domainID)
34 The “ibm,associativity-reference-points” property contains a list of one or more numbers
36 The list of domainID indexes represents an increasing hierarchy of resource grouping.
44 level of the resource group, the kernel doubles the NUMA distance between the
52 "ibm,associativity-reference-points" property, Form 2 allows a large number of primary domain
53 ids at the same domainID index representing resource groups of different performance/latency
56 Hypervisor indicates the usage of FORM2 associativity using bit 2 of byte 5 in the
59 "ibm,numa-lookup-index-table" property contains a list of one or more numbers representing
60 the domainIDs present in the system. The offset of the domainID in this property is
63 prop-encoded-array: The number N of the domainIDs encoded as with encode-int, followed by
67 "ibm,numa-lookup-index-table" = {4, 0, 8, 250, 252}. The offset of domainID 8 (2) is used when
68 computing the distance of domain 8 from other domains present in the system. For the rest of
71 "ibm,numa-distance-table" property contains a list of one or more numbers representing the NUMA
74 prop-encoded-array: The number N of the distance values encoded as with encode-int, followed by
76 The number N must be equal to the square of m where m is the number of domainIDs in the
102 "ibm,lookup-index-table" helps in having a compact representation of distance matrix.
103 Since domainID can be sparse, the matrix of distances can also be effectively sparse.
104 With "ibm,lookup-index-table" we can achieve a compact representation of
