#define CHECK_PARAM_BUFFER_PRM_HANDLER_GUID {0x2e4f2d13, 0x6240, 0x4ed0, {0xa4, 0x01, 0xc7, 0x23, 0xfb, 0xdc, 0x34, 0xe8}}

PRM_HANDLER_EXPORT ( CheckParamBufferPrmHandler )

A sample Platform Runtime Mechanism (PRM) handler.

This sample handler checks if a parameter buffer is provided with the data signature ('T', 'E', 'S', 'T') at the beginning of the buffer.

The contents are expected to be updated by ACPI code at OS runtime.

Parameters

[in]	ParameterBuffer	A pointer to the PRM handler parameter buffer
[in]	ContextBUffer	A pointer to the PRM handler context buffer

Return values

EFI_STATUS	The PRM handler executed successfully.
Others	An error occurred in the PRM handler.

EFI_STATUS EFIAPI PrmSampleAcpiParameterBufferModuleInit	(	IN EFI_HANDLE	ImageHandle,
		IN EFI_SYSTEM_TABLE *	SystemTable
	)

Module entry point.

Parameters

[in]	ImageHandle	The image handle.
[in]	SystemTable	A pointer to the system table.

Return values

EFI_SUCCESS This function always returns success.
