_WHEA_ERROR_PACKET_V2 structure

Description

The WHEA_ERROR_PACKET_V2 structure describes the hardware error data that is passed to the operating system by a low-level hardware error handler (LLHEH).

Members

`Signature`

The signature of the hardware error packet. This member contains the value WHEA_ERROR_PACKET_V2_SIGNATURE.

`Version`

The version of the WHEA_ERROR_PACKET_V2 structure. This member contains the value WHEA_ERROR_PACKET_V2_VERSION.

`Length`

`Flags`

A WHEA_ERROR_PACKET_FLAGS union that describes the error condition.

`ErrorType`

A WHEA_ERROR_TYPE-typed value that indicates the type of hardware component that reported the hardware error.

`ErrorSeverity`

A WHEA_ERROR_SEVERITY-typed value that indicates the severity of the error condition.

`ErrorSourceId`

The identifier of the error source that reported the hardware error.

`ErrorSourceType`

A WHEA_ERROR_SOURCE_TYPE-typed value that indicates the type of error source that reported the hardware error.

`NotifyType`

`Context`

Reserved for system use.

`DataFormat`

`Reserved1`

Reserved for system use.

`DataOffset`

`DataLength`

`PshedDataOffset`

`PshedDataLength`

Remarks

The WHEA_ERROR_PACKET_V2 structure is used to report a hardware error in Windows 7 and later versions of Windows.

If your platform-specific hardware error driver (PSHED) plug-ins run on any WHEA-compatible Windows version, You can inspect the version of WHEA_ERROR_PACKET by following these steps:

If the Signature member for the WHEA_ERROR_PACKET equals WHEA_ERROR_PACKET_V1_SIGNATURE, the code is running on an early version of Windows, and the error packet is formatted as a WHEA_ERROR_PACKET_V1 structure.
If the Signature member for the WHEA_ERROR_PACKET equals WHEA_ERROR_PACKET_V2_SIGNATURE, the code is running on a later version of Windows, and the error packet is formatted as a WHEA_ERROR_PACKET_V2 structure.

An LLHEH passes a WHEA_ERROR_PACKET_V2 structure to the operating system when it reports a hardware error. This hardware error packet contains the raw hardware error data direct from the error source's error status registers.

The WHEA_ERROR_PACKET_V2 structure describes the error data that is contained in a hardware error packet error section of an error record. An error record contains a hardware error packet error section only if the SectionType member of one of the WHEA_ERROR_RECORD_SECTION_DESCRIPTOR structures that describe the error record sections for that error record contains WHEA_PACKET_SECTION_GUID.
