The WHEA_XPF_TLB_CHECK union describes translation lookaside buffer (TLB) error information for an x86 or x64 processor.
DUMMYSTRUCTNAMEDUMMYSTRUCTNAME.TransactionTypeValidA single bit that indicates that the TransactionType member contains valid data.
DUMMYSTRUCTNAME.OperationValidA single bit that indicates that the Operation member contains valid data.
DUMMYSTRUCTNAME.LevelValidA single bit that indicates that the Level member contains valid data.
DUMMYSTRUCTNAME.ProcessorContextCorruptValidA single bit that indicates that the ProcessorContextCorrupt member contains valid data.
DUMMYSTRUCTNAME.UncorrectedValidA single bit that indicates that the Uncorrected member contains valid data.
DUMMYSTRUCTNAME.PreciseIPValidA single bit that indicates that the PreciseIP member contains valid data.
DUMMYSTRUCTNAME.RestartableIPValidA single bit that indicates that the RestartableIP member contains valid data.
DUMMYSTRUCTNAME.OverflowValidA single bit that indicates that the Overflow member contains valid data.
DUMMYSTRUCTNAME.ReservedValidReserved for system use.
DUMMYSTRUCTNAME.TransactionTypeThe type of transaction that was in progress when the error occurred. Possible values are:
This member contains valid data only if the TransactionTypeValid bit is set.
DUMMYSTRUCTNAME.OperationThe type of translation lookaside buffer (TLB) access operation that caused the error. Possible values are:
This member contains valid data only if the OperationValid bit is set.
DUMMYSTRUCTNAME.LevelThe level of the TLB where the error occurred.
This member contains valid data only if the LevelValid bit is set.
DUMMYSTRUCTNAME.ProcessorContextCorruptA single bit that indicates that the processor context might have been corrupted.
This member contains valid data only if the ProcessorContextCorruptValid bit is set.
DUMMYSTRUCTNAME.UncorrectedA single bit that indicates that the error has not been corrected.
This member contains valid data only if the UncorrectedValid bit is set.
DUMMYSTRUCTNAME.PreciseIPA single bit that indicates that the instruction pointer that is specified in the InstructionPointer member of the WHEA_XPF_PROCINFO structure that contains this WHEA_XPF_TLB_CHECK union is directly associated with the error.
This member contains valid data only if the PreciseIPValid bit is set.
DUMMYSTRUCTNAME.RestartableIPA single bit that indicates that program execution can be restarted reliably at the instruction pointer that is specified in the InstructionPointer member of the WHEA_XPF_PROCINFO union that contains this WHEA_XPF_TLB_CHECK structure.
This member contains valid data only if the RestartableIPValid bit is set.
DUMMYSTRUCTNAME.OverflowA single bit that indicates that an error overflow occurred.
This member contains valid data only if the OverflowValid bit is set.
DUMMYSTRUCTNAME.ReservedReserved for system use.
XpfTLBCheckA ULONGLONG representation of the contents of the WHEA_XPF_TLB_CHECK union.
A data read operation.
A data write operation.
The type of operation cannot be determined.
A generic read operation.
A generic write operation.
An instruction fetch operation.
An instruction prefetch operation.
A data access transaction.
A generic transaction.
A processor instruction transaction.
If the CheckInfoId member of a WHEA_XPF_PROCINFO structure contains WHEA_TLBCHECK_GUID, the CheckInfo member of the WHEA_XPF_PROCINFO structure contains a WHEA_XPF_TLB_CHECK union.
