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 the reporting of link training errors is masked.
DUMMYSTRUCTNAME.Reserved1
Reserved.
DUMMYSTRUCTNAME.DataLinkProtocolError
A single bit that indicates that the reporting of data link protocol errors is masked.
DUMMYSTRUCTNAME.SurpriseDownError
A single bit that indicates that the reporting of surprise down errors is masked.
DUMMYSTRUCTNAME.Reserved2
Reserved.
DUMMYSTRUCTNAME.PoisonedTLP
A single bit that indicates that the reporting of poisoned transaction layer packets (TLPs) is masked.
DUMMYSTRUCTNAME.FlowControlProtocolError
A single bit that indicates that the reporting of flow control protocol errors is masked.
DUMMYSTRUCTNAME.CompletionTimeout
A single bit that indicates that the reporting of completion timeouts is masked.
DUMMYSTRUCTNAME.CompleterAbort
A single bit that indicates that the reporting of completer aborts is masked.
DUMMYSTRUCTNAME.UnexpectedCompletion
A single bit that indicates that the reporting of unexpected completions is masked.
DUMMYSTRUCTNAME.ReceiverOverflow
A single bit that indicates that the reporting of receiver overflows is masked.
DUMMYSTRUCTNAME.MalformedTLP
A single bit that indicates that the reporting of malformed transaction layer packets (TLPs) is masked.
DUMMYSTRUCTNAME.ECRCError
A single bit that indicates that the reporting of end-to-end cyclic redundancy check (ECRC) errors is masked.
DUMMYSTRUCTNAME.UnsupportedRequestError
A single bit that indicates that the reporting of unsupported request errors is masked.
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_MASK structure.
Remarks
The PCI_EXPRESS_UNCORRECTABLE_ERROR_MASK structure is available in Windows Server 2008 and later versions of Windows.
A PCI_EXPRESS_UNCORRECTABLE_ERROR_MASK structure is contained in the PCI_EXPRESS_AER_CAPABILITY, PCI_EXPRESS_BRIDGE_AER_CAPABILITY, and PCI_EXPRESS_ROOTPORT_AER_CAPABILITY structures.
