Typedef Documentation

typedef EFI_STATUS(EFIAPI * EDKII_TCG_HASH_LOG_EXTEND_EVENT)(IN EDKII_TCG_PPI *This, IN UINT64 Flags, IN UINT8 *HashData, IN UINTN HashDataLen, IN TCG_PCR_EVENT_HDR *NewEventHdr, IN UINT8 *NewEventData)

Tpm measure and log data, and extend the measurement result into a specific PCR.

Parameters

[in]	This	Indicates the calling context
[in]	Flags	Bitmap providing additional information
[in]	HashData	If BIT0 of Flags is 0, it is physical address of the start of the data buffer to be hashed, extended, and logged. If BIT0 of Flags is 1, it is physical address of the start of the pre-hash data buffter to be extended, and logged. The pre-hash data format is TPML_DIGEST_VALUES.
[in]	HashDataLen	The length, in bytes, of the buffer referenced by HashData.
[in]	NewEventHdr	Pointer to a TCG_PCR_EVENT_HDR data structure.
[in]	NewEventData	Pointer to the new event data.

Return values

EFI_SUCCESS	Operation completed successfully.
EFI_UNSUPPORTED	TPM device not available.
EFI_OUT_OF_RESOURCES	Out of memory.
EFI_DEVICE_ERROR	The operation was unsuccessful.
