Members
DUMMYSTRUCTNAME
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
DUMMYSTRUCTNAME.UncorrectableInternalError
DUMMYSTRUCTNAME.MCBlockedTlp
DUMMYSTRUCTNAME.AtomicOpEgressBlocked
DUMMYSTRUCTNAME.TlpPrefixBlocked
DUMMYSTRUCTNAME.PoisonedTlpEgressBlocked
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.
