19 Checks the parameter of SmbusExecute().
21 This function checks the input parameters of SmbusExecute(). If the input parameters are valid
22 for certain SMBus bus protocol, it will return EFI_SUCCESS; otherwise, it will return certain
23 error code based on the input SMBus bus protocol.
25 @param SmBusAddress Address that encodes the SMBUS Slave Address, SMBUS Command, SMBUS Data Length,
27 @param Operation Signifies which particular SMBus hardware protocol instance that
28 it will use to execute the SMBus transactions. This SMBus
29 hardware protocol is defined by the SMBus Specification and is
31 @param Length Signifies the number of bytes that this operation will do. The
32 maximum number of bytes can be revision specific and operation
33 specific. This field will contain the actual number of bytes that
34 are executed for this operation. Not all operations require this
36 @param Buffer Contains the value of data to execute to the SMBus slave device.
37 Not all operations require this argument. The length of this
38 buffer is identified by Length.
40 @retval EFI_SUCCESS All the parameters are valid for the corresponding SMBus bus
42 @retval EFI_INVALID_PARAMETER Operation is not defined in EFI_SMBUS_OPERATION.

120 Executes an SMBus operation to an SMBus controller. Returns when either the command has been
121 executed or an error is encountered in doing the operation.
123 The SmbusExecute() function provides a standard way to execute an operation as defined in the System
124 Management Bus (SMBus) Specification. The resulting transaction will be either that the SMBus
125 slave devices accept this transaction or that this function returns with error.
