- @param[in] Command This command is transmitted by the SMBus host
- controller to the SMBus slave device, and the

- @param[in] Operation Signifies which particular SMBus hardware protocol
- instance to use to execute the SMBus transactions.
- @param[in] PecCheck Defines if Packet Error Code (PEC) checking is
- required for this operation.
- @param[in, out] Length The number of bytes for this operation.
- @param[in, out] Buffer Contains the value of data to execute to the SMBus
- slave device.
-
- @retval EFI_SUCCESS The last data that was returned from the access
- matched the poll exit criteria.
- @retval EFI_CRC_ERROR The 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
- was recorded in the Host Status Register bit.
- @retval EFI_INVALID_PARAMETER The 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.
