WHEA_XPF_PROCESSOR_ERROR_SECTION structure

  • Article

The WHEA_XPF_PROCESSOR_ERROR_SECTION structure describes processor error data that is specific to the x86/x64 processor architecture.

Syntax

typedef struct _WHEA_XPF_PROCESSOR_ERROR_SECTION {
  WHEA_XPF_PROCESSOR_ERROR_SECTION_VALIDBITS ValidBits;
  ULONGLONG                                  LocalAPICId;
  UCHAR                                      CpuId[48];
  UCHAR                                      VariableInfo[ANYSIZE_ARRAY];
} WHEA_XPF_PROCESSOR_ERROR_SECTION, *PWHEA_XPF_PROCESSOR_ERROR_SECTION;

Members

  • ValidBits
    A WHEA_XPF_PROCESSOR_ERROR_SECTION_VALIDBITS union that specifies which members of this structure contain valid data and the number of structures that are contained in the VariableInfo member.

  • LocalAPICId
    The value programmed into the local APIC ID register.

    This member contains valid data only if the ValidBits.LocalAPICId bit is set.

  • CpuId
    A 48-byte buffer that contains the results of executing the CPUID instruction. For more information about the CPUID instruction, see the Intel 64 and IA-32 Architectures Software Developer's Manual.

    This member contains valid data only if the ValidBits.CpuId bit is set.

  • VariableInfo
    A variable length buffer that contains zero or more WHEA_XPF_PROCINFO structures followed by zero or more WHEA_XPF_CONTEXT_INFO structures. The number of WHEA_XPF_PROCINFO structures is specified in ValidBits.ProcInfoCount. The number of WHEA_XPF_CONTEXT_INFO structures is specified in ValidBits.ContextInfoCount. For a diagram that shows how these data structures are stored in the buffer, see the Remarks section.

Remarks

The WHEA_XPF_PROCESSOR_ERROR_SECTION structure describes the error data that is contained in an x86/x64 processor error section of an error record. An error record contains an x86/x64 processor error section only if the SectionType member of one of the WHEA_ERROR_RECORD_SECTION_DESCRIPTOR structures that describes the error record sections for that error record contains XPF_PROCESSOR_ERROR_SECTION_GUID.

The following diagram shows how the data structures that contain the processor error data are stored in the VariableInfo member.
