ArmGicCInfoParser()

EFI_STATUS EFIAPI ArmGicCInfoParser	(	IN CONST FDT_HW_INFO_PARSER_HANDLE	FdtParserHandle,
		IN INT32	FdtBranch
	)

CM_ARM_GICC_INFO parser function.

This parser expects FdtBranch to be the "\cpus" node node. At most one CmObj is created. The following structure is populated: typedef struct CmArmGicCInfo { UINT32 CPUInterfaceNumber; // {Populated} UINT32 AcpiProcessorUid; // {Populated} UINT32 Flags; // {Populated} UINT32 ParkingProtocolVersion; // {default = 0} UINT32 PerformanceInterruptGsiv; // {Populated} UINT64 ParkedAddress; // {default = 0} UINT64 PhysicalBaseAddress; // {Populated} UINT64 GICV; // {Populated} UINT64 GICH; // {Populated} UINT32 VGICMaintenanceInterrupt; // {Populated} UINT64 GICRBaseAddress; // {default = 0} UINT64 MPIDR; // {Populated} UINT8 ProcessorPowerEfficiencyClass; // {default = 0} UINT16 SpeOverflowInterrupt; // {default = 0} UINT32 ProximityDomain; // {default = 0} UINT32 ClockDomain; // {default = 0} UINT32 AffinityFlags; // {default = 0} } CM_ARM_GICC_INFO;

A parser parses a Device Tree to populate a specific CmObj type. None, one or many CmObj can be created by the parser. The created CmObj are then handed to the parser's caller through the HW_INFO_ADD_OBJECT interface. This can also be a dispatcher. I.e. a function that not parsing a Device Tree but calling other parsers.

Parameters

[in]	FdtParserHandle	A handle to the parser instance.
[in]	FdtBranch	When searching for DT node name, restrict the search to this Device Tree branch.

Return values

EFI_SUCCESS	The function completed successfully.
EFI_ABORTED	An error occurred.
EFI_INVALID_PARAMETER	Invalid parameter.
EFI_NOT_FOUND	Not found.
EFI_UNSUPPORTED	Unsupported.
