WHEA_PCIXDEVICE_ERROR_SECTION structure

The WHEA_PCIXDEVICE_ERROR_SECTION structure describes PCI or PCI-X device error data.

Syntax


typedef struct _WHEA_PCIXDEVICE_ERROR_SECTION {
  WHEA_PCIXDEVICE_ERROR_SECTION_VALIDBITS ValidBits;
  WHEA_ERROR_STATUS                       ErrorStatus;
  WHEA_PCIXDEVICE_ID                      IdInfo;
  ULONG                                   MemoryNumber;
  ULONG                                   IoNumber;
  WHEA_PCIXDEVICE_REGISTER_PAIR           RegisterDataPairs[ANYSIZE_ARRAY];
} WHEA_PCIXDEVICE_ERROR_SECTION, *PWHEA_PCIXDEVICE_ERROR_SECTION;

Members

ValidBits

A WHEA_PCIXDEVICE_ERROR_SECTION_VALIDBITS union that specifies which members of this structure contain valid data.

ErrorStatus

A WHEA_ERROR_STATUS structure that contains PCI or PCI-X device error status data.

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

IdInfo

A WHEA_PCIXDEVICE_ID structure that contains data that identifies the PCI or PCI-X device. The WHEA_PCIXDEVICE_ID structure is defined as follows:


typedef struct _WHEA_PCIXDEVICE_ID {
  USHORT  VendorId;
  USHORT  DeviceId;
  ULONG  ClassCode:24;
  ULONG  FunctionNumber:8;
  ULONG  DeviceNumber:8;
  ULONG  BusNumber:8;
  ULONG  SegmentNumber:8;
  ULONG  Reserved1:8;
  ULONG  Reserved2;
} WHEA_PCIXDEVICE_ID, *PWHEA_PCIXDEVICE_ID;

VendorId

The vendor ID of the device.

DeviceId

The device ID of the device.

ClassCode

The class code of the device.

FunctionNumber

The function number of the device on the bus.

DeviceNumber

The device number of the device on the bus.

BusNumber

The number of the bus that contains the device.

SegmentNumber

The number of the bus segment that contains the device.

Reserved1

Reserved for system use.

Reserved2

Reserved for system use.

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

MemoryNumber

The number of memory mapped register address/data pair values from the PCI device that are included in the RegisterDataPairs member.

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

IoNumber

The number of I/O mapped register address/data pair values from the PCI device that are included in the RegisterDataPairs member.

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

RegisterDataPairs

An array of WHEA_PCIXDEVICE_REGISTER_PAIR structures that contains the register address/data pair values for the PCI device. The WHEA_PCIXDEVICE_REGISTER_PAIR structure is defined as follows:


typedef struct WHEA_PCIXDEVICE_REGISTER_PAIR {
  ULONGLONG  Register;
  ULONGLONG  Data;
} WHEA_PCIXDEVICE_REGISTER_PAIR, *PWHEA_PCIXDEVICE_REGISTER_PAIR;

Register

The address of the register.

Data

The data contained in the register.

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

Remarks

The WHEA_PCIXDEVICE_ERROR_SECTION structure describes the error data that is contained in a PCI/PCI-X device error section of an error record. An error record contains a PCI/PCI-X device error section only if the SectionType member of one of the WHEA_ERROR_RECORD_SECTION_DESCRIPTOR structures that describe the error record sections for that error record contains PCIXBUS_ERROR_SECTION_GUID.

Requirements

Version

Supported in Windows Server 2008, Windows Vista SP1, and later versions of Windows.
