ParseAcpiApmt()

VOID EFIAPI ParseAcpiApmt	(	IN BOOLEAN	Trace,
		IN UINT8 *	Ptr,
		IN UINT32	AcpiTableLength,
		IN UINT8	AcpiTableRevision
	)

This function parses the ACPI APMT table. When trace is enabled this function parses the APMT table and traces the ACPI table fields.

This function also performs validation of the ACPI table fields.

Parameters

[in]	Trace	If TRUE, trace the ACPI fields.
[in]	Ptr	Pointer to the start of the buffer.
[in]	AcpiTableLength	Length of the ACPI table.
[in]	AcpiTableRevision	Revision of the ACPI table.
