The EFI_TREE_PROTOCOL GetCapability function call provides protocol capability information and state information about the TrEE.
[in] | This | Indicates the calling context |
[out] | ProtocolCapability | The caller allocates memory for a TREE_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 TrEE state information up to the number of fields which fit within the size of the structure passed in. |
EFI_SUCCESS | Operation completed successfully. | |
EFI_DEVICE_ERROR | The command was unsuccessful. The ProtocolCapability variable will not be populated. | |
EFI_INVALID_PARAMETER | One or more of the parameters are incorrect. The ProtocolCapability variable will not be populated. | |
EFI_BUFFER_TOO_SMALL | The ProtocolCapability variable is too small to hold the full response. It will be partially populated (required Size field will be set). |
[in] | This | Indicates the calling context |
[in] | EventLogFormat | The type of the event log for which the information is requested. |
[out] | EventLogLocation | A pointer to the memory address of the event log. |
[out] | 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. |
[out] | EventLogTruncated | If 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. |
EFI_SUCCESS | Operation completed successfully. | |
EFI_INVALID_PARAMETER | One or more of the parameters are incorrect (e.g. asking for an event log whose format is not supported). |
[in] | This | Indicates the calling context |
[in] | Flags | Bitmap providing additional information. |
[in] | DataToHash | Physical address of the start of the data buffer to be hashed. |
[in] | DataToHashLen | The length in bytes of the buffer referenced by DataToHash. |
[in] | Event | Pointer to data buffer containing information about the event. |
EFI_SUCCESS | Operation completed successfully. | |
EFI_DEVICE_ERROR | The command was unsuccessful. | |
EFI_VOLUME_FULL | The extend operation occurred, but the event could not be written to one or more event logs. | |
EFI_INVALID_PARAMETER | One or more of the parameters are incorrect. | |
EFI_UNSUPPORTED | The PE/COFF image type is not supported. |
[in] | This | Indicates the calling context |
[in] | InputParameterBlockSize | Size of the TrEE input parameter block. |
[in] | InputParameterBlock | Pointer to the TrEE input parameter block. |
[in] | OutputParameterBlockSize | Size of the TrEE output parameter block. |
[in] | OutputParameterBlock | Pointer to the TrEE output parameter block. |
EFI_SUCCESS | The command byte stream was successfully sent to the device and a response was successfully received. | |
EFI_DEVICE_ERROR | The command was not successfully sent to the device or a response was not successfully received from the device. | |
EFI_INVALID_PARAMETER | One or more of the parameters are incorrect. | |
EFI_BUFFER_TOO_SMALL | The output parameter block is too small. |
