Windows system information processor

SYSTEM_LOGICAL_PROCESSOR_INFORMATION structure (winnt.h)

Describes the relationship between the specified processor set. This structure is used with the GetLogicalProcessorInformation function.

Syntax

Members

The processor mask identifying the processors described by this structure. A processor mask is a bit vector in which each set bit represents an active processor in the relationship. At least one bit will be set.

On a system with more than 64 processors, the processor mask identifies processors in a single processor group.

The relationship between the processors identified by the value of the ProcessorMask member. This member can be one of the following LOGICAL_PROCESSOR_RELATIONSHIP values.

Value Meaning
RelationCache 2 The specified logical processors share a cache. The Cache member contains additional information.

Windows ServerВ 2003:В В This value is not supported until Windows ServerВ 2003 with SP1 and WindowsВ XP Professional x64 Edition.

RelationNumaNode 1 The specified logical processors are part of the same NUMA node. The NumaNode member contains additional information.
RelationProcessorCore 0 The specified logical processors share a single processor core. The ProcessorCore member contains additional information.
RelationProcessorPackage 3 The specified logical processors share a physical package. There is no additional information available.

Windows ServerВ 2003 and WindowsВ XP Professional x64 Edition:В В This value is not supported until Windows ServerВ 2003 with SP1 and WindowsВ XP with SP3.

Future versions of Windows may support additional values for the Relationship member.

This structure contains valid data only if the Relationship member is RelationProcessorCore.

If the value of this member is 1, the logical processors identified by the value of the ProcessorMask member share functional units, as in Hyperthreading or SMT. Otherwise, the identified logical processors do not share functional units.

Windows ServerВ 2003 and WindowsВ XP Professional x64 Edition:В В This member is also 1 for cores that share a physical package. Therefore, to determine whether the processor supports multiple cores or hyperthreading on systems prior to WindowsВ Vista, use the CPUID instruction.

This structure contains valid data only if the Relationship member is RelationNumaNode.

Identifies the NUMA node. The valid values of this parameter are 0 to the highest NUMA node number inclusive. A non-NUMA multiprocessor system will report that all processors belong to one NUMA node.

A CACHE_DESCRIPTOR structure that identifies the characteristics of a particular cache. There is one record returned for each cache reported. Some or all caches may not be reported, depending on the mechanism used by the processor to identify its caches. Therefore, do not assume the absence of any particular caches. Caches are not necessarily shared among logical processors.

This structure contains valid data only if the Relationship member is RelationCache.

Windows ServerВ 2003:В В This member is not supported until Windows ServerВ 2003 with SP1 and WindowsВ XP Professional x64 Edition.

SYSTEM_INFO structure (sysinfoapi.h)

Contains information about the current computer system. This includes the architecture and type of the processor, the number of processors in the system, the page size, and other such information.

Syntax

Members

An obsolete member that is retained for compatibility. Applications should use the wProcessorArchitecture branch of the union.

The processor architecture of the installed operating system. This member can be one of the following values.

Value Meaning
PROCESSOR_ARCHITECTURE_AMD64 9 x64 (AMD or Intel)
PROCESSOR_ARCHITECTURE_ARM 5 ARM
PROCESSOR_ARCHITECTURE_ARM64 12 ARM64
PROCESSOR_ARCHITECTURE_IA64 6 Intel Itanium-based
PROCESSOR_ARCHITECTURE_INTEL 0 x86
PROCESSOR_ARCHITECTURE_UNKNOWN 0xffff Unknown architecture.

This member is reserved for future use.

The page size and the granularity of page protection and commitment. This is the page size used by the VirtualAlloc function.

A pointer to the lowest memory address accessible to applications and dynamic-link libraries (DLLs).

A pointer to the highest memory address accessible to applications and DLLs.

A mask representing the set of processors configured into the system. Bit 0 is processor 0; bit 31 is processor 31.

The number of logical processors in the current group. To retrieve this value, use the GetLogicalProcessorInformation function.

An obsolete member that is retained for compatibility. Use the wProcessorArchitecture, wProcessorLevel, and wProcessorRevision members to determine the type of processor.

PROCESSOR_INTEL_386 (386)

PROCESSOR_INTEL_486 (486)

PROCESSOR_INTEL_PENTIUM (586)

PROCESSOR_INTEL_IA64 (2200)

PROCESSOR_AMD_X8664 (8664)

PROCESSOR_ARM (Reserved)

The granularity for the starting address at which virtual memory can be allocated. For more information, see VirtualAlloc.

The architecture-dependent processor level. It should be used only for display purposes. To determine the feature set of a processor, use the IsProcessorFeaturePresent function.

If wProcessorArchitecture is PROCESSOR_ARCHITECTURE_INTEL, wProcessorLevel is defined by the CPU vendor.

If wProcessorArchitecture is PROCESSOR_ARCHITECTURE_IA64, wProcessorLevel is set to 1.

The architecture-dependent processor revision. The following table shows how the revision value is assembled for each type of processor architecture.

Processor Value
Intel Pentium, Cyrix, or NextGen 586 The high byte is the model and the low byte is the stepping. For example, if the value is xxyy, the model number and stepping can be displayed as follows:

Model xx, Stepping yy

Intel 80386 or 80486 A value of the form xxyz.

If xx is equal to 0xFF, y — 0xA is the model number, and z is the stepping identifier.

If xx is not equal to 0xFF, xx + ‘A’ is the stepping letter and yz is the minor stepping.

Windows Processor Requirements

This specification details the processors that can be used with Customer Systems that include Windows Products (including Custom Images). Updates to this specification may be released in the future as requirements change.

For each listed edition, Company must use only the processors listed, as specified in the tables below. The requirements below apply whenever the edition below is pre-installed or provided on external media, including as downgrade or down edition software.

For clarity, Company must also meet all processor and other requirements specified in Minimum Hardware Requirements for Windows 10, located at https://msdn.microsoft.com/library/windows/hardware/dn915086(v=vs.85).aspx (or updated URL).

If after the inclusion of a processor series in this specification (“Listed Processor”), a processor becomes commercially available that uses the same naming convention or identifier as a Listed Processor but has additional or different features or functionality (“New Processor”), Company must not use New Processor for Customer Systems without Microsoft’s prior written permission. If Company believes a processor has been omitted from this list, please contact Company’s Microsoft OEM or ODM Account Manager.
