Description

The PCI_EXPRESS_ROOTPORT_AER_CAPABILITY structure describes a PCI Express (PCIe) advanced error reporting capability structure for a root port or a root complex event collector.

Members

Header

A PCI_EXPRESS_ENHANCED_CAPABILITY_HEADER structure that describes the header for this structure.

UncorrectableErrorStatus

A PCI_EXPRESS_UNCORRECTABLE_ERROR_STATUS structure that describes the PCIe uncorrectable error status register of the PCIe AER capability structure.

UncorrectableErrorMask

A PCI_EXPRESS_UNCORRECTABLE_ERROR_MASK structure that describes the PCIe uncorrectable error mask register of the PCIe AER capability structure.

UncorrectableErrorSeverity

A PCI_EXPRESS_UNCORRECTABLE_ERROR_SEVERITY structure that describes the PCIe uncorrectable error severity register of the PCIe AER capability structure.

CorrectableErrorStatus

A PCI_EXPRESS_UNCORRECTABLE_ERROR_STATUS structure that describes the PCIe uncorrectable error status register of the PCIe AER capability structure.

CorrectableErrorMask

A PCI_EXPRESS_UNCORRECTABLE_ERROR_MASK structure that describes the PCIe uncorrectable error mask register of the PCIe AER capability structure.

CapabilitiesAndControl

A PCI_EXPRESS_AER_CAPABILITIES structure that describes the PCIe advanced error capabilities and control register of the PCIe AER capability structure.

HeaderLog

An array of four 32-bit values that together contain the header for the transaction layer packet (TLP) that corresponds to a detected error.

Within each 32-bit value in the array, the bytes of the TLP are in big-endian byte order.

RootErrorCommand

A PCI_EXPRESS_ROOT_ERROR_COMMAND structure that describes the PCIe root error command register of the PCIe AER capability structure.

RootErrorStatus

A PCI_EXPRESS_ROOT_ERROR_STATUS structure that describes the PCIe root error status register of the PCIe AER capability structure.

ErrorSourceId

A PCI_EXPRESS_ERROR_SOURCE_ID structure that describes the PCIe error source identification register of the PCIe AER capability structure.

} PCI_EXPRESS_ROOTPORT_AER_CAPABILITY, *PPCI_EXPRESS_ROOTPORT_AER_CAPABILITY;

Remarks

The PCI_EXPRESS_ROOTPORT_AER_CAPABILITY structure is available in Windows Server 2008 and later versions of Windows.

PCIe bridge devices use the PCI_EXPRESS_BRIDGE_AER_CAPABILITY structure instead of the PCI_EXPRESS_ROOTPORT_AER_CAPABILITY structure to describe the PCIe advanced error reporting capability structure.

All other PCIe devices and ports that are not root ports or root complex event collectors use the PCI_EXPRESS_AER_CAPABILITY structure instead of the PCI_EXPRESS_ROOTPORT_AER_CAPABILITY structure to describe the PCIe advanced error reporting capability structure.

For additional information about the PCIe advanced error reporting capability structure, see the PCI Express Specification.
