/** Code generation for the "Interrupt ()" ASL function.
|
||
|
|
|
||
|
|
This function creates a Resource Data element corresponding to the
|
||
|
|
"Interrupt ()" ASL function and stores it in an AML Data Node.
|
||
|
|
|
||
|
|
The Resource Data effectively created is an Extended Interrupt Resource
|
||
|
|
Data. See ACPI 6.3 specification, s6.4.3.6 "Extended Interrupt Descriptor"
|
||
|
|
for more information about Extended Interrupt Resource Data.
|
||
|
|
|
||
|
|
This function allocates memory to create a data node. It is the caller's
|
||
|
|
responsibility to either:
|
||
|
|
- attach this node to an AML tree;
|
||
|
|
- delete this node.
|
||
|
|
|
||
|
|
@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] ParentNode If not NULL, add the generated node
|
||
|
|
to the end of the variable list of
|
||
|
|
argument of the ParentNode, but
|
||
|
|
before the "End Tag" Resource Data.
|
||
|
|
Must be a BufferOpNode.
|
||
|
|
@param [out] NewRdNode If success, contains the generated node.
|
||
|
|
|
||
|
|
@retval EFI_SUCCESS The function completed successfully.
|
||
|
|
@retval EFI_INVALID_PARAMETER Invalid parameter.
|
||
|
|
@retval EFI_OUT_OF_RESOURCES Could not allocate memory.
