◆ EFI_TCG2_GET_ACTIVE_PCR_BANKS

typedef EFI_STATUS(EFIAPI * EFI_TCG2_GET_ACTIVE_PCR_BANKS) (IN EFI_TCG2_PROTOCOL *This, OUT UINT32 *ActivePcrBanks)

This service returns the currently active PCR banks.

Parameters
[in]ThisIndicates the calling context
[out]ActivePcrBanksPointer to the variable receiving the bitmap of currently active PCR banks.
Return values
EFI_SUCCESSThe bitmap of active PCR banks was stored in the ActivePcrBanks parameter.
EFI_INVALID_PARAMETEROne or more of the parameters are incorrect.

Definition at line 257 of file Tcg2Protocol.h.

◆ EFI_TCG2_GET_CAPABILITY

typedef EFI_STATUS(EFIAPI * EFI_TCG2_GET_CAPABILITY) (IN EFI_TCG2_PROTOCOL *This, IN OUT EFI_TCG2_BOOT_SERVICE_CAPABILITY *ProtocolCapability)

The EFI_TCG2_PROTOCOL GetCapability function call provides protocol capability information and state information.

Parameters
[in]ThisIndicates the calling context
[in,out]ProtocolCapabilityThe caller allocates memory for a EFI_TCG2_BOOT_SERVICE_CAPABILITY structure and sets the size field to the size of the structure allocated. The callee fills in the fields with the EFI protocol capability information and the current EFI TCG2 state information up to the number of fields which fit within the size of the structure passed in.
Return values
EFI_SUCCESSOperation completed successfully.
EFI_DEVICE_ERRORThe command was unsuccessful. The ProtocolCapability variable will not be populated.
EFI_INVALID_PARAMETEROne or more of the parameters are incorrect. The ProtocolCapability variable will not be populated.
EFI_BUFFER_TOO_SMALLThe ProtocolCapability variable is too small to hold the full response. It will be partially populated (required Size field will be set).

◆ EFI_TCG2_GET_EVENT_LOG

typedef EFI_STATUS(EFIAPI * EFI_TCG2_GET_EVENT_LOG) (IN EFI_TCG2_PROTOCOL *This, IN EFI_TCG2_EVENT_LOG_FORMAT EventLogFormat, OUT EFI_PHYSICAL_ADDRESS *EventLogLocation, OUT EFI_PHYSICAL_ADDRESS *EventLogLastEntry, OUT BOOLEAN *EventLogTruncated)

The EFI_TCG2_PROTOCOL Get Event Log function call allows a caller to retrieve the address of a given event log and its last entry.

Parameters
[in]ThisIndicates the calling context
[in]EventLogFormatThe type of the event log for which the information is requested.
[out]EventLogLocationA pointer to the memory address of the event log.
[out]EventLogLastEntryIf 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.
[out]EventLogTruncatedIf the Event Log is missing at least one entry because an event would have exceeded the area allocated for events, this value is set to TRUE. Otherwise, the value will be FALSE and the Event Log will be complete.
Return values
EFI_SUCCESSOperation completed successfully.
EFI_INVALID_PARAMETEROne or more of the parameters are incorrect (e.g. asking for an event log whose format is not supported).

Definition at line 185 of file Tcg2Protocol.h.

◆ EFI_TCG2_GET_RESULT_OF_SET_ACTIVE_PCR_BANKS

typedef EFI_STATUS(EFIAPI * EFI_TCG2_GET_RESULT_OF_SET_ACTIVE_PCR_BANKS) (IN EFI_TCG2_PROTOCOL *This, OUT UINT32 *OperationPresent, OUT UINT32 *Response)

This service retrieves the result of a previous invocation of SetActivePcrBanks.

Parameters
[in]ThisIndicates the calling context
[out]OperationPresentNon-zero value to indicate a SetActivePcrBank operation was invoked during the last boot.
[out]ResponseThe response from the SetActivePcrBank request.
Return values
EFI_SUCCESSThe result value could be returned.
EFI_INVALID_PARAMETEROne or more of the parameters are incorrect.

Definition at line 290 of file Tcg2Protocol.h.

◆ EFI_TCG2_HASH_LOG_EXTEND_EVENT

typedef EFI_STATUS(EFIAPI * EFI_TCG2_HASH_LOG_EXTEND_EVENT) (IN EFI_TCG2_PROTOCOL *This, IN UINT64 Flags, IN EFI_PHYSICAL_ADDRESS DataToHash, IN UINT64 DataToHashLen, IN EFI_TCG2_EVENT *EfiTcgEvent)

The EFI_TCG2_PROTOCOL HashLogExtendEvent function call provides callers with an opportunity to extend and optionally log events without requiring knowledge of actual TPM commands. The extend operation will occur even if this function cannot create an event log entry (e.g. due to the event log being full).

Parameters
[in]ThisIndicates the calling context
[in]FlagsBitmap providing additional information.
[in]DataToHashPhysical address of the start of the data buffer to be hashed.
[in]DataToHashLenThe length in bytes of the buffer referenced by DataToHash.
[in]EfiTcgEventPointer to data buffer containing information about the event.
Return values
EFI_SUCCESSOperation completed successfully.
EFI_DEVICE_ERRORThe command was unsuccessful.
EFI_VOLUME_FULLThe extend operation occurred, but the event could not be written to one or more event logs.
EFI_INVALID_PARAMETEROne or more of the parameters are incorrect.
EFI_UNSUPPORTEDThe PE/COFF image type is not supported.

◆ EFI_TCG2_SET_ACTIVE_PCR_BANKS

typedef EFI_STATUS(EFIAPI * EFI_TCG2_SET_ACTIVE_PCR_BANKS) (IN EFI_TCG2_PROTOCOL *This, IN UINT32 ActivePcrBanks)

This service sets the currently active PCR banks.

Parameters
[in]ThisIndicates the calling context
[in]ActivePcrBanksBitmap of the requested active PCR banks. At least one bit SHALL be set.
Return values
EFI_SUCCESSThe bitmap in ActivePcrBank parameter is already active.
EFI_INVALID_PARAMETEROne or more of the parameters are incorrect.

Definition at line 273 of file Tcg2Protocol.h.

◆ EFI_TCG2_SUBMIT_COMMAND

typedef EFI_STATUS(EFIAPI * EFI_TCG2_SUBMIT_COMMAND) (IN EFI_TCG2_PROTOCOL *This, IN UINT32 InputParameterBlockSize, IN UINT8 *InputParameterBlock, IN UINT32 OutputParameterBlockSize, IN UINT8 *OutputParameterBlock)

This service enables the sending of commands to the TPM.

Parameters
[in]ThisIndicates the calling context
[in]InputParameterBlockSizeSize of the TPM input parameter block.
[in]InputParameterBlockPointer to the TPM input parameter block.
[in]OutputParameterBlockSizeSize of the TPM output parameter block.
[in]OutputParameterBlockPointer to the TPM output parameter block.
Return values
EFI_SUCCESSThe command byte stream was successfully sent to the device and a response was successfully received.
EFI_DEVICE_ERRORThe command was not successfully sent to the device or a response was not successfully received from the device.
EFI_INVALID_PARAMETEROne or more of the parameters are incorrect.
EFI_BUFFER_TOO_SMALLThe output parameter block is too small.
