Foreword The HP CPU Profile P00106 was prepared by the HP WBEM TC. Version 1.0.
Introduction The information in this specification should be sufficient for a provider or consumer of this data to identify unambiguously the classes, properties, methods, and values that shall be instantiated and manipulated to represent logical CPUs in HP systems (support for physical CPU information is optional). The target audience for this specification is implementers who are writing CIM based providers or consumers of management interfaces representing the component described in this document.
1 Scope The HP CPU profile extends the management capability of referencing profiles by adding the capability to represent the logical CPUs in HP specific ways. 2 Normative References The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. 2.1 Approved References DMTF DSP0200, CIM Operations over HTTP 1.2.
3.4 mandatory used to indicate requirements strictly to be followed in order to conform to the document and from which no deviation is permitted 3.5 may used to indicate a course of action permissible within the limits of the document 3.6 need not used to indicate a course of action permissible within the limits of the document 3.7 optional used to indicate a course of action permissible within the limits of the document 3.

A relationship between a logical processor (HP_Processor) or a logical processor core (HP_ProcessorCore) and a cache memory (HP_CacheMemory) that is used by the processor is represented by the HP_AssociatedProcessorCacheMemory class. The physical processor is represented by the HP_ProcessorChip class. The HP_PhysicalCacheMemory class is used when the cache is external to the processor.
8 Methods None. 8.1 Profile Conventions for Operations Support for operations for each profile class (including associations) is specified in the following subclauses. Each sub-clause includes either a statement “All operations are supported as described by DSP200 v1.2” or a table listing all the operations that are Unspecified by this profile or where the profile requires behavior other that described by DSP200.
Table 4 – Operations: HP_ProcessorCore Operation Requirement GetInstance Mandatory Messages None Associators Unspecified None AssociatorNames Unspecified None References Unspecified None ReferenceNames Unspecified None EnumerateInstances Unspecified None EnumerateInstanceNames Unspecified None 8.4 HP_HardwareThread The table below lists operations that either have special requirements beyond those from DSP0200 or shall not be supported.
9 Use Cases 9.1 Object Diagrams The following represents a possible instantiation of the HP CPU Profile. In this case, system1 has one processor with 2 cores. Each of the cores has one hardware thread. For simplicity most of the properties have been removed from the classes.
