PCI_EXPRESS_AER_CAPABILITIES union (wdm.h)

  • Article

The PCI_EXPRESS_AER_CAPABILITIES structure describes a PCI Express (PCIe) advanced error capabilities and control register of a PCIe advanced error reporting capability structure.

Syntax

typedef union _PCI_EXPRESS_AER_CAPABILITIES {
  struct {
    ULONG FirstErrorPointer  :5;
    ULONG ECRCGenerationCapable  :1;
    ULONG ECRCGenerationEnable  :1;
    ULONG ECRCCheckCapable  :1;
    ULONG ECRCCheckEnable  :1;
    ULONG Reserved  :23;
  };
  ULONG  AsULONG;
} PCI_EXPRESS_AER_CAPABILITIES, *PPCI_EXPRESS_AER_CAPABILITIES;

Members

DUMMYSTRUCTNAME

DUMMYSTRUCTNAME.FirstErrorPointer

The bit position of the first error that was reported in the PCIe uncorrectable error status register.

DUMMYSTRUCTNAME.ECRCGenerationCapable

A single bit that indicates that the device is capable of generating end-to-end cyclic redundancy checks (ECRC).

DUMMYSTRUCTNAME.ECRCGenerationEnable

A single bit that indicates that ECRC generation is enabled.

DUMMYSTRUCTNAME.ECRCCheckCapable

A single bit that indicates that the device is capable of checking ECRC.

DUMMYSTRUCTNAME.ECRCCheckEnable

A single bit that indicates that ECRC checking is enabled.

DUMMYSTRUCTNAME.MultipleHeaderRecordingCapable

DUMMYSTRUCTNAME.MultipleHeaderRecordingEnable

DUMMYSTRUCTNAME.TlpPrefixLogPresent

DUMMYSTRUCTNAME.Reserved

Reserved.

AsULONG

A ULONG representation of the contents of the PCI_EXPRESS_AER_CAPABILITIES structure.

Remarks

The PCI_EXPRESS_AER_CAPABILITIES structure is available in Windows Server 2008 and later versions of Windows.

A PCI_EXPRESS_AER_CAPABILITIES structure is contained in the PCI_EXPRESS_AER_CAPABILITY, PCI_EXPRESS_BRIDGE_AER_CAPABILITY, and PCI_EXPRESS_ROOTPORT_AER_CAPABILITY structures.
