Function Documentation

AmlUpdateRdInterruptEx()

EFI_STATUS EFIAPI AmlUpdateRdInterruptEx	(	IN AML_DATA_NODE_HANDLE	InterruptRdNode,
		IN BOOLEAN	ResourceConsumer,
		IN BOOLEAN	EdgeTriggered,
		IN BOOLEAN	ActiveLow,
		IN BOOLEAN	Shared,
		IN UINT32 *	IrqList,
		IN UINT8	IrqCount
	)

Update the interrupt list of an interrupt resource data node.

The InterruptRdNode corresponds to the Resource Data created by the "Interrupt ()" ASL function. It 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.

Parameters

[in]	InterruptRdNode	Pointer to the an extended interrupt resource data node.
[in]	ResourceConsumer	The device consumes the specified interrupt or produces it for use by a child device.
[in]	EdgeTriggered	The interrupt is edge triggered or level triggered.
[in]	ActiveLow	The interrupt is active-high or active-low.
[in]	Shared	The interrupt can be shared with other devices or not (Exclusive).
[in]	IrqList	Interrupt list. Must be non-NULL.
[in]	IrqCount	Interrupt count. Must be non-zero.

Return values

EFI_SUCCESS	The function completed successfully.
EFI_INVALID_PARAMETER	Invalid parameter.
EFI_OUT_OF_RESOURCES	Out of resources.
