EfiPciIoAttributeOperationGet
Retrieve the PCI controller’s current attributes, and return them in Result. If Result
is NULL, then EFI_INVALID_PARAMER is returned. For this operation,
Attributes is ignored.
EfiPciIoAttributeOperationSet
Set the PCI controller’s current attributes to Attributes. If a bit is set in
Attributes that is not supported by this PCI controller or one of its parent bridges,
then EFI_UNSUPPORTED is returned. For this operation, Result is an optional
parameter that may be NULL.
EfiPciIoAttributeOperationEnable
Enable the attributes specified by the bits that are set in Attributes for this PCI
controller. Bits in Attributes that are clear are ignored. If a bit is set in
Attributes that is not supported by this PCI controller or one of its parent bridges,
then EFI_UNSUPPORTED is returned. For this operation, Result is an optional
parameter that may be NULL.
EfiPciIoAttributeOperationDisable
Disable the attributes specified by the bits that are set in Attributes for this PCI
controller. Bits in Attributes that are clear are ignored. If a bit is set in
Attributes that is not supported by this PCI controller or one of its parent bridges,
then EFI_UNSUPPORTED is returned. For this operation, Result is an optional
parameter that may be NULL.
EfiPciIoAttributeOperationSupported
Retrieve the PCI controller's supported attributes, and return them in Result. If
Result is NULL, then EFI_INVALID_PARAMER is returned. For this operation,
Attributes is ignored.
