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 link training error has occurred.

DUMMYSTRUCTNAME.Reserved1

Reserved.

DUMMYSTRUCTNAME.DataLinkProtocolError

A single bit that indicates that a data link protocol error has occurred.

DUMMYSTRUCTNAME.SurpriseDownError

A single bit that indicates that a surprise down error has occurred.

DUMMYSTRUCTNAME.Reserved2

Reserved.

DUMMYSTRUCTNAME.PoisonedTLP

A single bit that indicates that a poisoned transaction layer packet (TLP) has been detected.

DUMMYSTRUCTNAME.FlowControlProtocolError

A single bit that indicates that a flow control protocol error has occurred.

DUMMYSTRUCTNAME.CompletionTimeout

A single bit that indicates that a completion timeout has occurred.

DUMMYSTRUCTNAME.CompleterAbort

A single bit that indicates that a completer abort has occurred.

DUMMYSTRUCTNAME.UnexpectedCompletion

A single bit that indicates that an unexpected completion has occurred.

DUMMYSTRUCTNAME.ReceiverOverflow

A single bit that indicates that the receiver has overflowed.

DUMMYSTRUCTNAME.MalformedTLP

A single bit that indicates that a malformed transaction layer packet (TLP) has been detected.

DUMMYSTRUCTNAME.ECRCError

A single bit that indicates that an end-to-end cyclic redundancy check (ECRC) error has occurred.

DUMMYSTRUCTNAME.UnsupportedRequestError

A single bit that indicates that an unsupported request error has occurred.

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_STATUS structure.

Remarks

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

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

Requirements
