WHEA_ERROR_PACKET_FLAGS union (ntddk.h)

The WHEA_ERROR_PACKET_FLAGS union defines the error condition reported through a WHEA_ERROR_PACKET structure.

Syntax

typedef union _WHEA_ERROR_PACKET_FLAGS {
  struct {
    ULONG PreviousError : 1;
    ULONG CriticalEvent : 1;
    ULONG HypervisorError : 1;
    ULONG Simulated : 1;
    ULONG PlatformPfaControl : 1;
    ULONG PlatformDirectedOffline : 1;
    ULONG AddressTranslationRequired : 1;
    ULONG AddressTranslationCompleted : 1;
    ULONG RecoveryOptional : 1;
    ULONG Reserved2 : 23;
  } DUMMYSTRUCTNAME;
  ULONG  AsULONG;
} WHEA_ERROR_PACKET_FLAGS, *PWHEA_ERROR_PACKET_FLAGS;

Members

DUMMYSTRUCTNAME

DUMMYSTRUCTNAME.PreviousError

A single bit that indicates whether the hardware error packet contains information about a fatal hardware error. This error caused the operating system to generate a bug check and restart.

DUMMYSTRUCTNAME.CriticalEvent

DUMMYSTRUCTNAME.HypervisorError

A single bit that indicates that a hypervisor error has occurred.

DUMMYSTRUCTNAME.Simulated

A single bit that indicates that the error condition was simulated.

DUMMYSTRUCTNAME.PlatformPfaControl

A single bit that indicates whether WHEA or a PSHED plug-in is in control of predictive failure analysis (PFA). If this bit is set, the PSHED plug-in is in control of PFA and must set the PlatformDirectedOffline to bring an ECC memory page into an offline state.

For more information about PFA support for WHEA, see Predictive Failure Analysis (PFA).

Note  This member is supported in Windows 7 and later versions of Windows.
 

DUMMYSTRUCTNAME.PlatformDirectedOffline

A single bit that indicates whether the PSHED plug-in that performs PFA on a system component has determined if the component should be brought into an offline state. This bit is only valid if the PlatformPfaControl member is set.

Note  This member is supported in Windows 7 and later versions of Windows.
 

DUMMYSTRUCTNAME.AddressTranslationRequired

DUMMYSTRUCTNAME.AddressTranslationCompleted

DUMMYSTRUCTNAME.RecoveryOptional

DUMMYSTRUCTNAME.Reserved2

Reserved for system use.

AsULONG

A ULONG representation of the contents of the WHEA_ERROR_PACKET_FLAGS union.

Remarks

The WHEA_ERROR_PACKET_FLAGS union describes the error condition reported by using a WHEA_ERROR_PACKET structure.

Requirements

   
Minimum supported client Supported in Windows Server 2008, Windows Vista SP1, and later versions of Windows.
