- @param SlaveAddress The SMBus slave address of the device with which to communicate.
- @param Command This command is transmitted by the SMBus host
- controller to the SMBus slave device and the interpretation is
- SMBus slave device specific.
- @param Operation Signifies which particular SMBus hardware protocol
- instance that it will use to execute the SMBus transactions.
- @param PecCheck Defines if Packet Error Code (PEC) checking is required
- for this operation.
- @param Length Signifies the number of bytes that this operation will do.
- @param 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 reflected in the Host Status Register bit.
- @retval EFI_INVALID_PARAMETER Operation is not defined in EFI_SMBUS_OPERATION.
- Or 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.
