Function Documentation

GetNitoMetadataFromMemory()

SIPLStatus nvsipl::GetNitoMetadataFromMemory	(	uint8_t const *const	nitoMem,
		size_t const	nitoMemLength,
		NvSIPLNitoMetadata *const	metadataArray,
		size_t const	metadataArrayLength,
		size_t *const	metadataCount
	)

Get NITO Metadata (knobset UUID, schema hash, data hash) from a NITO memory buffer.

This function is wrapper function around Tuna::bbf::target::fetchNitoMetadataFromMemory(). It inspects parameter data then calls fetchNitoMetadataFromMemory, performs error code conversion between Tuna and SIPL, then copies metadata into the return value.

The possible return values from this functions are:

• NVSIPL_STATUS_OK
• NVSIPL_STATUS_BAD_ARGUMENT
• NVSIPL_STATUS_INVALID_STATE
• NVSIPL_STATUS_OUT_OF_MEMORY
• NVSIPL_STATUS_ERROR These have been mapped to corresponding Tuna::bbf::BBF_Result codes returned from Tuna::bbf::target::fetchNitoMetadataFromMemory(), which is called within this function. The mapping can be found in sipl/src/core/utils/tunaUtils.hpp. Each mapping also includes logs with information on the error.

Parameters

[in]	nitoMem	Pointer to location of memory to load from.
[in]	nitoMemLength	Size of memory pointed to by nitoMem. This value must be in the range [1, BBF_FILE_MAX_SIZE].
[in,out]	metadataArray	An array of NitoMetadata tuples to store the result.
[in]	metadataArrayLength	The size of array metadataArray
[out]	metadataCount	The number of tuples stored in metadataArray on success.

Returns

SIPLStatus the completion status of the operation.
