WHEA_XPF_BUS_CHECK union (ntddk.h)

  • Article

The WHEA_XPF_BUS_CHECK union describes bus error information for an x86 or x64 processor.

DUMMYSTRUCTNAME.LevelValid

A single bit that indicates that the Level member contains valid data.

DUMMYSTRUCTNAME.ProcessorContextCorruptValid

A single bit that indicates that the ProcessorContextCorrupt member contains valid data.

DUMMYSTRUCTNAME.UncorrectedValid

A single bit that indicates that the Uncorrected member contains valid data.

DUMMYSTRUCTNAME.PreciseIPValid

A single bit that indicates that the PreciseIP member contains valid data.

DUMMYSTRUCTNAME.RestartableIPValid

A single bit that indicates that the RestartableIP member contains valid data.

DUMMYSTRUCTNAME.OverflowValid

A single bit that indicates that the Overflow member contains valid data.

DUMMYSTRUCTNAME.ParticipationValid

A single bit that indicates that the Participation member contains valid data.

DUMMYSTRUCTNAME.TimeoutValid

A single bit that indicates that the Timeout member contains valid data.

DUMMYSTRUCTNAME.AddressSpaceValid

A single bit that indicates that the AddressSpace member contains valid data.

DUMMYSTRUCTNAME.ReservedValid

Reserved for system use.

DUMMYSTRUCTNAME.TransactionType

The 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.Operation

The type of bus operation that caused the error. Possible values are:

This member contains valid data only if the OperationValid bit is set.

DUMMYSTRUCTNAME.Level

The level of the bus hierarchy where the error occurred.

This member contains valid data only if the LevelValid bit is set.

DUMMYSTRUCTNAME.ProcessorContextCorrupt

A 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.Uncorrected

A single bit that indicates that the error has not been corrected.

This member contains valid data only if the UncorrectedValid bit is set.

DUMMYSTRUCTNAME.PreciseIP

A 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_BUS_CHECK union is directly associated with the error.

This member contains valid data only if the PreciseIPValid bit is set.

DUMMYSTRUCTNAME.RestartableIP

A 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_BUS_CHECK structure.

This member contains valid data only if the RestartableIPValid bit is set.

DUMMYSTRUCTNAME.Overflow

A single bit that indicates that an error overflow occurred.

This member contains valid data only if the OverflowValid bit is set.

DUMMYSTRUCTNAME.Participation

The type of participation by the local processor. Possible values are:

This member contains valid data only if the ParticipationValid bit is set.

DUMMYSTRUCTNAME.Timeout

A single bit that indicates that a timeout occurred.

This member contains valid data only if the TimeoutValid bit is set.

DUMMYSTRUCTNAME.AddressSpace

The type of address space that was associated with the transaction that caused the error. Possible values are:

This member contains valid data only if the AddressSpaceValid bit is set.

DUMMYSTRUCTNAME.Reserved

Reserved for system use.

XpfBusCheck

A ULONGLONG representation of the contents of the WHEA_XPF_BUS_CHECK union.

Remarks

If the CheckInfoId member of a WHEA_XPF_PROCINFO structure contains WHEA_BUSCHECK_GUID, the CheckInfo member of the WHEA_XPF_PROCINFO structure contains a WHEA_XPF_BUS_CHECK union.
