flags

public byte flags

If the WinNT.SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EX.relationship member of the WinNT.SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EX structure is WinNT.LOGICAL_PROCESSOR_RELATIONSHIP.RelationProcessorCore, this member is WinNT.LTP_PC_SMT if the core has more than one logical processor, or 0 if the core has one logical processor.

If the WinNT.SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EX.relationship member of the WinNT.SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EX structure is WinNT.LOGICAL_PROCESSOR_RELATIONSHIP.RelationProcessorPackage, this member is always 0.

efficiencyClass

public byte efficiencyClass

If the WinNT.SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EX.relationship member of the WinNT.SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EX structure is WinNT.LOGICAL_PROCESSOR_RELATIONSHIP.RelationProcessorCore, EfficiencyClass specifies the intrinsic tradeoff between performance and power for the applicable core. A core with a higher value for the efficiency class has intrinsically greater performance and less efficiency than a core with a lower value for the efficiency class. EfficiencyClass is only nonzero on systems with a heterogeneous set of cores.

If the WinNT.SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EX.relationship member of the WinNT.SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EX structure is WinNT.LOGICAL_PROCESSOR_RELATIONSHIP.RelationProcessorPackage, EfficiencyClass is always 0.

The minimum operating system version that supports this member is Windows 10.

reserved

public byte[] reserved

This member is reserved.

groupCount

public short groupCount

This member specifies the number of entries in the GroupMask array.

If the PROCESSOR_RELATIONSHIP structure represents a processor core, the GroupCount member is always 1.

If the WinNT.PROCESSOR_RELATIONSHIP structure represents a processor package, the groupCount member is 1 only if all processors are in the same processor group. If the package contains more than one NUMA node, the system might assign different NUMA nodes to different processor groups. In this case, the groupCount member is the number of groups to which NUMA nodes in the package are assigned.

groupMask

public WinNT.GROUP_AFFINITY[] groupMask

An array of WinNT.GROUP_AFFINITY structures. The groupCount member specifies the number of structures in the array. Each structure in the array specifies a group number and processor affinity within the group.
