Individual bit fields

◆ LogicalProcessors

UINT32 CPUID_EXTENDED_TOPOLOGY_EBX::LogicalProcessors

[Bits 15:0] Number of logical processors at this level type. The number reflects configuration as shipped by Intel.

Note
Software must not use EBX[15:0] to enumerate processor topology of the system. This value in this field (EBX[15:0]) is only intended for display/diagnostic purposes. The actual number of logical processors available to BIOS/OS/Applications may be different from the value of EBX[15:0], depending on software and platform hardware configurations.
