This service abstracts the capability to do a hash operation on a data buffer.
| This | Indicates the calling context. |
| HashData | The pointer to the data buffer to be hashed. |
| HashDataLen | The length of the data buffer to be hashed. |
| AlgorithmId | Identification of the Algorithm to use for the hashing operation. |
| HashedDataLen | Resultant length of the hashed data. |
| HashedDataResult | Resultant buffer of the hashed data. |
| EFI_SUCCESS | The operation completed successfully. |
| EFI_INVALID_PARAMETER | HashDataLen is NULL. |
| EFI_INVALID_PARAMETER | HashDataLenResult is NULL. |
| EFI_OUT_OF_RESOURCES | Cannot allocate buffer of size *HashedDataLen. |
| EFI_UNSUPPORTED | AlgorithmId not supported. |
| EFI_BUFFER_TOO_SMALL | *HashedDataLen < sizeof (TCG_DIGEST). |
| typedef EFI_STATUS(EFIAPI * EFI_TCG_HASH_LOG_EXTEND_EVENT)(IN EFI_TCG_PROTOCOL *This, IN EFI_PHYSICAL_ADDRESS HashData, IN UINT64 HashDataLen, IN TCG_ALGORITHM_ID AlgorithmId, IN OUT TCG_PCR_EVENT *TCGLogData, IN OUT UINT32 *EventNumber, OUT EFI_PHYSICAL_ADDRESS *EventLogLastEntry) |
This service abstracts the capability to do a hash operation on a data buffer, extend a specific TPM PCR with the hash result, and add an entry to the Event Log
| This | Indicates the calling context |
| HashData | The physical address of the start of the data buffer to be hashed, extended, and logged. |
| HashDataLen | The length, in bytes, of the buffer referenced by HashData |
| AlgorithmId | Identification of the Algorithm to use for the hashing operation |
| TCGLogData | The physical address of the start of the data buffer containing the TCG_PCR_EVENT data structure. |
| EventNumber | The event number of the event just logged. |
| EventLogLastEntry | The physical address of the first byte of the entry just placed in the Event Log. If the Event Log was empty when this function was called then this physical address will be the same as the physical address of the start of the Event Log. |
| EFI_SUCCESS | The operation completed successfully. |
| EFI_UNSUPPORTED | AlgorithmId != TPM_ALG_SHA. |
| EFI_UNSUPPORTED | Current TPL >= EFI_TPL_CALLBACK. |
| EFI_DEVICE_ERROR | The command was unsuccessful. |
| typedef EFI_STATUS(EFIAPI * EFI_TCG_LOG_EVENT)(IN EFI_TCG_PROTOCOL *This, IN TCG_PCR_EVENT *TCGLogData, IN OUT UINT32 *EventNumber, IN UINT32 Flags) |
This service abstracts the capability to add an entry to the Event Log.
| This | Indicates the calling context |
| TCGLogData | The pointer to the start of the data buffer containing the TCG_PCR_EVENT data structure. All fields in this structure are properly filled by the caller. |
| EventNumber | The event number of the event just logged. |
| Flags | Indicates additional flags. Only one flag has been defined at this time, which is 0x01 and means the extend operation should not be performed. All other bits are reserved. |
| EFI_SUCCESS | The operation completed successfully. |
| EFI_OUT_OF_RESOURCES | Insufficient memory in the event log to complete this action. |
| typedef EFI_STATUS(EFIAPI * EFI_TCG_PASS_THROUGH_TO_TPM)(IN EFI_TCG_PROTOCOL *This, IN UINT32 TpmInputParameterBlockSize, IN UINT8 *TpmInputParameterBlock, IN UINT32 TpmOutputParameterBlockSize, IN UINT8 *TpmOutputParameterBlock) |
This service is a proxy for commands to the TPM.
| This | Indicates the calling context. |
| TpmInputParameterBlockSize | Size of the TPM input parameter block. |
| TpmInputParameterBlock | The pointer to the TPM input parameter block. |
| TpmOutputParameterBlockSize | Size of the TPM output parameter block. |
| TpmOutputParameterBlock | The pointer to the TPM output parameter block. |
| EFI_SUCCESS | The operation completed successfully. |
| EFI_INVALID_PARAMETER | Invalid ordinal. |
| EFI_UNSUPPORTED | Current Task Priority Level >= EFI_TPL_CALLBACK. |
| EFI_TIMEOUT | The TIS timed-out. |

| typedef EFI_STATUS(EFIAPI * EFI_TCG_STATUS_CHECK)(IN EFI_TCG_PROTOCOL *This, OUT TCG_EFI_BOOT_SERVICE_CAPABILITY *ProtocolCapability, OUT UINT32 *TCGFeatureFlags, OUT EFI_PHYSICAL_ADDRESS *EventLogLocation, OUT EFI_PHYSICAL_ADDRESS *EventLogLastEntry) |
This service provides EFI protocol capability information, state information about the TPM, and Event Log state information.
| This | Indicates the calling context |
| ProtocolCapability | The callee allocates memory for a TCG_BOOT_SERVICE_CAPABILITY structure and fills in the fields with the EFI protocol capability information and the current TPM state information. |
| TCGFeatureFlags | This is a pointer to the feature flags. No feature flags are currently defined so this parameter MUST be set to 0. However, in the future, feature flags may be defined that, for example, enable hash algorithm agility. |
| EventLogLocation | This is a pointer to the address of the event log in memory. |
| EventLogLastEntry | If the Event Log contains more than one entry, this is a pointer to the address of the start of the last entry in the event log in memory. |
| EFI_SUCCESS | The operation completed successfully. |
| EFI_INVALID_PARAMETER | ProtocolCapability does not match TCG capability. |
