Rework all the functions to to have a generic prototype: - First take take the resource data specific arguments. E.g.: for a Register(): the AddressSpace, BitWidth, ... - The penultimate parameter is a NameOpNode. The resource data created is appended to the ResourceTemplate() contained in the NameOpNode. - The last parameter is a pointer holding the created resource data. A least one of the two last parameter must be provided. One of them can be omitted. This generic interface allows to either: - Add the resource data to a NameOpNode. This is a common case for the Ssdt tables generator. - Get the created resource data and let the caller place it in an AML tree.

/** Code generation for the "Interrupt ()" ASL function.
|
|
|
|
The Resource Data effectively created is an Extended Interrupt Resource
|
|
Data. Cf ACPI 6.4:
|
|
- s6.4.3.6 "Extended Interrupt Descriptor"
|
|
- s19.6.64 "Interrupt (Interrupt Resource Descriptor Macro)"
|
|
|
|
The created resource data node can be:
|
|
- appended to the list of resource data elements of the NameOpNode.
|
|
In such case NameOpNode must be defined by a the "Name ()" ASL statement
|
|
and initially contain a "ResourceTemplate ()".
|
|
- returned through the NewRdNode parameter.
|
|
|
|
@param [in] ResourceConsumer The device consumes the specified interrupt
|
|
or produces it for use by a child device.
|
|
@param [in] EdgeTriggered The interrupt is edge triggered or
|
|
level triggered.
|
|
@param [in] ActiveLow The interrupt is active-high or active-low.
|
|
@param [in] Shared The interrupt can be shared with other
|
|
devices or not (Exclusive).
|
|
@param [in] IrqList Interrupt list. Must be non-NULL.
|
|
@param [in] IrqCount Interrupt count. Must be non-zero.
|
|
@param [in] NameOpNode NameOp object node defining a named object.
|
|
If provided, append the new resource data node
|
|
to the list of resource data elements of this
|
|
node.
|
|
@param [out] NewRdNode If provided and success,
|
|
contain the created node.
|
|
|
|
@retval EFI_SUCCESS The function completed successfully.
|
|
@retval EFI_INVALID_PARAMETER Invalid parameter.
|
|
@retval EFI_OUT_OF_RESOURCES Could not allocate memory.
