Resources subsets of a given domain that exhibit better +performance relative to each other than relative to other resources subsets +are represented as being members of a sub-grouping domain. This performance +characteristic is presented in terms of NUMA node distance within the Linux kernel. +From the platform view, these groups are also referred to as domains. + +PAPR interface currently supports different ways of communicating these resource +grouping details to the OS. These are referred to as Form 0, Form 1 and Form2 +associativity grouping. Form 0 is the oldest format and is now considered deprecated. + +Hypervisor indicates the type/form of associativity used via "ibm,architecture-vec-5 property". +Bit 0 of byte 5 in the "ibm,architecture-vec-5" property indicates usage of Form 0 or Form 1. +A value of 1 indicates the usage of Form 1 associativity. For Form 2 associativity +bit 2 of byte 5 in the "ibm,architecture-vec-5" property is used. + +Form 0 +----- +Form 0 associativity supports only two NUMA distances (LOCAL and REMOTE). + +Form 1 +----- +With Form 1 a combination of ibm,associativity-reference-points, and ibm,associativity +device tree properties are used to determine the NUMA distance between resource groups/domains. + +The “ibm,associativity” property contains a list of one or more numbers (domainID) +representing the resource’s platform grouping domains. + +The “ibm,associativity-reference-points” property contains a list of one or more numbers +(domainID index) that represents the 1 based ordinal in the associativity lists. +The list of domainID indexes represents an increasing hierarchy of resource grouping. + +ex: +{ primary domainID index, secondary domainID index, tertiary domainID index.. } + +Linux kernel uses the domainID at the primary domainID index as the NUMA node id. +Linux kernel computes NUMA distance between two domains by recursively comparing +if they belong to the same higher-level domains. For mismatch at every higher +level of the resource group, the kernel doubles the NUMA distance between the +comparing domains. + +Form 2 +------- +Form 2 associativity format adds separate device tree properties representing NUMA node distance +thereby making the node distance computation flexible. Form 2 also allows flexible primary +domain numbering. With numa distance computation now detached from the index value in +"ibm,associativity-reference-points" property, Form 2 allows a large number of primary domain +ids at the same domainID index representing resource groups of different performance/latency +characteristics. + +Hypervisor indicates the usage of FORM2 associativity using bit 2 of byte 5 in the +"ibm,architecture-vec-5" property. + +"ibm,numa-lookup-index-table" property contains a list of one or more numbers representing +the domainIDs present in the system.
