| /** | |
| Executes an SMBus operation to an SMBus controller. Returns when either the command has been | |
| executed or an error is encountered in doing the operation. | |
| The SmbusExecute() function provides a standard way to execute an operation as defined in the System | |
| Management Bus (SMBus) Specification. The resulting transaction will be either that the SMBus | |
| slave devices accept this transaction or that this function returns with error. | |
| @param SmbusAddress Address that encodes the SMBUS Slave Address, SMBUS Command, SMBUS Data Length, | |
| and PEC. | |
| @param Operation Signifies which particular SMBus hardware protocol instance that | |
| it will use to execute the SMBus transactions. This SMBus | |
| hardware protocol is defined by the SMBus Specification and is | |
| not related to EFI. | |
| @param Length Signifies the number of bytes that this operation will do. The | |
| maximum number of bytes can be revision specific and operation | |
| specific. This field will contain the actual number of bytes that | |
| are executed for this operation. Not all operations require this | |
| argument. | |
| @param Buffer Contains the value of data to execute to the SMBus slave device. | |
| Not all operations require this argument. The length of this | |
| buffer is identified by Length. | |
| @retval EFI_SUCCESS The last data that was returned from the access matched the poll | |
| exit criteria. | |
| @retval EFI_CRC_ERROR Checksum is not correct (PEC is incorrect). | |
| @retval EFI_TIMEOUT Timeout expired before the operation was completed. Timeout is | |
| determined by the SMBus host controller device. | |
| @retval EFI_OUT_OF_RESOURCES The request could not be completed due to a lack of resources. | |
| @retval EFI_DEVICE_ERROR The request was not completed because a failure that was | |
| reflected in the Host Status Register bit. Device errors are a | |
| result of a transaction collision, illegal command field, | |
| unclaimed cycle (host initiated), or bus errors (collisions). | |
| @retval EFI_INVALID_PARAMETER Operation is not defined in EFI_SMBUS_OPERATION. | |
| @retval EFI_INVALID_PARAMETER Length/Buffer is NULL for operations except for EfiSmbusQuickRead | |
| and EfiSmbusQuickWrite. Length is outside the range of valid | |
| values. | |
| @retval EFI_UNSUPPORTED The SMBus operation or PEC is not supported. | |
| @retval EFI_BUFFER_TOO_SMALL Buffer is not sufficient for this operation. | |
