Members

DUMMYSTRUCTNAME

The DUMMYSTRUCTNAME structure.

DUMMYSTRUCTNAME.Undefined

A single bit that contains an undefined value. In versions of the PCIe Specification prior to version 1.1, this bit indicates that a reported link training error is a fatal error.

DUMMYSTRUCTNAME.Reserved1

Reserved.

DUMMYSTRUCTNAME.DataLinkProtocolError

A single bit that indicates that a reported data link protocol error is a fatal error.

DUMMYSTRUCTNAME.SurpriseDownError

A single bit that indicates that a reported surprise down error is a fatal error.

DUMMYSTRUCTNAME.Reserved2

Reserved.

DUMMYSTRUCTNAME.PoisonedTLP

A single bit that indicates that a reported poisoned transaction layer packet (TLP) is a fatal error.

DUMMYSTRUCTNAME.FlowControlProtocolError

A single bit that indicates that a reported flow control protocol error is a fatal error.

DUMMYSTRUCTNAME.CompletionTimeout

A single bit that indicates that a reported completion timeout is a fatal error.

DUMMYSTRUCTNAME.CompleterAbort

A single bit that indicates that a reported completer abort is a fatal error.

DUMMYSTRUCTNAME.UnexpectedCompletion

A single bit that indicates that a reported unexpected completion is a fatal error.

DUMMYSTRUCTNAME.ReceiverOverflow

A single bit that indicates that a reported receiver overflow is a fatal error.

DUMMYSTRUCTNAME.MalformedTLP

A single bit that indicates that a reported malformed transaction layer packet (TLP) is a fatal error.

DUMMYSTRUCTNAME.ECRCError

A single bit that indicates that a reported end-to-end cyclic redundancy check (ECRC) error is a fatal error.

DUMMYSTRUCTNAME.UnsupportedRequestError

A single bit that indicates that a reported unsupported request error is a fatal error.

DUMMYSTRUCTNAME.AcsViolation

Defines the ULONG member AcsViolation.

DUMMYSTRUCTNAME.UncorrectableInternalError

Defines the ULONG member UncorrectableInternalError.

DUMMYSTRUCTNAME.MCBlockedTlp

Defines the ULONG member MCBlockedTlp.

DUMMYSTRUCTNAME.AtomicOpEgressBlocked

Defines the ULONG member AtomicOpEgressBlocked.

DUMMYSTRUCTNAME.TlpPrefixBlocked

Defines the ULONG member TlpPrefixBlocked.

DUMMYSTRUCTNAME.Reserved3

Reserved.

AsULONG

A ULONG representation of the contents of the PCI_EXPRESS_UNCORRECTABLE_ERROR_SEVERITY structure.

Remarks

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

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

Requirements

Requirement	Value
Header	miniport.h (include Ntddk.h, Wdm.h, Miniport.h)
