} WHEA_AER_BRIDGE_DESCRIPTOR, *PWHEA_AER_BRIDGE_DESCRIPTOR;
Members
Type
The type of error source descriptor. This member is always set to WHEA_ERROR_SOURCE_DESCRIPTOR_TYPE_AERBRIDGE.
Enabled
A Boolean value that indicates if the error source is enabled.
Reserved
Reserved for system use.
BusNumber
The bridge's primary bus number.
Slot
A WHEA_PCI_SLOT_NUMBER structure that describes the logical PCI slot where the bridge is located in the system.
DeviceControl
The contents of the bridge's Device Control register.
Flags
An AER_BRIDGE_DESCRIPTOR_FLAGS union that indicates which of the members of the WHEA_AER_BRIDGE_DESCRIPTOR structure can be written to by the operating system. The AER_BRIDGE_DESCRIPTOR_FLAGS union is defined as follows:
typedef union _AER_BRIDGE_DESCRIPTOR_FLAGS {
struct {
USHORT UncorrectableErrorMaskRW:1;
USHORT UncorrectableErrorSeverityRW:1;
USHORT CorrectableErrorMaskRW:1;
USHORT AdvancedCapsAndControlRW:1;
USHORT SecondaryUncorrectableErrorMaskRW:1;
USHORT SecondaryUncorrectableErrorSevRW:1;
USHORT SecondaryCapsAndControlRW:1;
USHORT Reserved:9;
};
USHORT AsUSHORT;
} AER_BRIDGE_DESCRIPTOR_FLAGS, *PAER_BRIDGE_DESCRIPTOR_FLAGS
UncorrectableErrorMaskRW
A single bit that indicates that the operating system can write to the UncorrectableErrorMask member of the WHEA_AER_BRIDGE_DESCRIPTOR structure.
UncorrectableErrorSeverityRW
A single bit that indicates that the operating system can write to the UncorrectableErrorSeverity member of the WHEA_AER_BRIDGE_DESCRIPTOR structure.
CorrectableErrorMaskRW
A single bit that indicates that the operating system can write to the CorrectableErrorMask member of the WHEA_AER_BRIDGE_DESCRIPTOR structure.
AdvancedCapsAndControlRW
A single bit that indicates that the operating system can write to the AdvancedCapsAndControl member of the WHEA_AER_BRIDGE_DESCRIPTOR structure.
SecondaryUncorrectableErrorMaskRW
A single bit that indicates that the operating system can write to the SecondaryUncorrectableErrorMask member of the WHEA_AER_BRIDGE_DESCRIPTOR structure.
SecondaryUncorrectableErrorSevRW
A single bit that indicates that the operating system can write to the SecondaryUncorrectableErrorSev member of the WHEA_AER_BRIDGE_DESCRIPTOR structure.
SecondaryCapsAndControlRW
A single bit that indicates that the operating system can write to the SecondaryCapsAndControl member of the WHEA_AER_BRIDGE_DESCRIPTOR structure.
Reserved
Reserved for system use.
AsUSHORT
A USHORT representation of the contents of the AER_ROOTPORT_DESCRIPTOR_FLAGS union.
UncorrectableErrorMask
The contents of the bridge's Uncorrectable Error Mask register.
UncorrectableErrorSeverity
The contents of the bridge's Uncorrectable Error Severity register.
CorrectableErrorMask
The contents of the bridge's Correctable Error Mask register.
AdvancedCapsAndControl
The contents of the bridge's Advanced Error Capabilities and Control register.
SecondaryUncorrectableErrorMask
The contents of the bridge's Secondary Uncorrectable Error Mask register.
SecondaryUncorrectableErrorSev
The contents of the bridge's Secondary Uncorrectable Error Severity register.
SecondaryCapsAndControl
The contents of the bridge's Secondary Error Capabilities and Control register.
Remarks
A WHEA_AER_BRIDGE_DESCRIPTOR structure is contained within the WHEA_ERROR_SOURCE_DESCRIPTOR structure.
