Function Documentation

DeregisterParser()

EFI_STATUS EFIAPI DeregisterParser

(

IN UINT32

Signature

)

Deregister the ACPI table Parser

This function deregisters the ACPI table parser.

Parameters

[in]

Signature

The ACPI table signature.

Return values

EFI_SUCCESS	The parser was deregistered.
EFI_INVALID_PARAMETER	A parameter is invalid.
EFI_NOT_FOUND	A registered parser was not found.

Definition at line 100 of file AcpiTableParser.c.

GetParser()

EFI_STATUS EFIAPI GetParser	(	IN UINT32	Signature,
		OUT PARSE_ACPI_TABLE_PROC *	ParserProc
	)

Get the ACPI table Parser

This function returns the ACPI table parser proc from the list of registered parsers.

Parameters

[in]	Signature	The ACPI table signature.
[out]	ParserProc	Pointer to a ACPI table parser proc.

Return values

EFI_SUCCESS	The parser was returned successfully.
EFI_INVALID_PARAMETER	A parameter is invalid.
EFI_NOT_FOUND	A registered parser was not found.

Definition at line 140 of file AcpiTableParser.c.

ProcessAcpiTable()

VOID EFIAPI ProcessAcpiTable

(

IN UINT8 *

Ptr

)

This function processes the ACPI tables. This function calls ProcessTableReportOptions() to list the ACPI tables, perform binary dump of the tables and determine if the ACPI fields should be traced.

This function also invokes the parser for the ACPI tables.

This function also performs a RAW dump of the ACPI table including the unknown/unparsed ACPI tables and validates the checksum.

Parameters

[in]

Ptr

Pointer to the start of the ACPI table data buffer.

RegisterParser()

EFI_STATUS EFIAPI RegisterParser	(	IN UINT32	Signature,
		IN PARSE_ACPI_TABLE_PROC	ParserProc
	)

Register the ACPI table Parser

This function registers the ACPI table parser.

Parameters

[in]	Signature	The ACPI table signature.
[in]	ParserProc	The ACPI table parser.

Return values

EFI_SUCCESS	The parser is registered.
EFI_INVALID_PARAMETER	A parameter is invalid.
EFI_ALREADY_STARTED	The parser for the Table was already registered.
EFI_OUT_OF_RESOURCES	No space to register the parser.
