12 | Executes an SMBus operation to an SMBus controller. Returns when either the command has been\r | |
13 | executed or an error is encountered in doing the operation.\r | |
14 | \r | |
15 | The SmbusExecute() function provides a standard way to execute an operation as defined in the System\r | |
16 | Management Bus (SMBus) Specification. The resulting transaction will be either that the SMBus\r | |
17 | slave devices accept this transaction or that this function returns with error.\r | |
18 | \r | |
3a03e95e | 19 | @param SmbusAddress Address that encodes the SMBUS Slave Address, SMBUS Command, SMBUS Data Length,\r |
64d14edf | 20 | and PEC.\r |
21 | @param Operation Signifies which particular SMBus hardware protocol instance that\r | |
22 | it will use to execute the SMBus transactions. This SMBus\r | |
23 | hardware protocol is defined by the SMBus Specification and is\r | |
24 | not related to EFI.\r | |
25 | @param Length Signifies the number of bytes that this operation will do. The\r | |
26 | maximum number of bytes can be revision specific and operation\r | |
27 | specific. This field will contain the actual number of bytes that\r | |
28 | are executed for this operation. Not all operations require this\r | |
29 | argument.\r | |
30 | @param Buffer Contains the value of data to execute to the SMBus slave device.\r | |
31 | Not all operations require this argument. The length of this\r | |
32 | buffer is identified by Length.\r | |
33 | \r | |
34 | @retval EFI_SUCCESS The last data that was returned from the access matched the poll\r | |
35 | exit criteria.\r | |
36 | @retval EFI_CRC_ERROR Checksum is not correct (PEC is incorrect).\r | |
37 | @retval EFI_TIMEOUT Timeout expired before the operation was completed. Timeout is\r | |
38 | determined by the SMBus host controller device.\r | |
39 | @retval EFI_OUT_OF_RESOURCES The request could not be completed due to a lack of resources.\r | |
40 | @retval EFI_DEVICE_ERROR The request was not completed because a failure that was\r | |
41 | reflected in the Host Status Register bit. Device errors are a\r | |
42 | result of a transaction collision, illegal command field,\r | |
43 | unclaimed cycle (host initiated), or bus errors (collisions).\r | |
44 | @retval EFI_INVALID_PARAMETER Operation is not defined in EFI_SMBUS_OPERATION.\r | |
45 | @retval EFI_INVALID_PARAMETER Length/Buffer is NULL for operations except for EfiSmbusQuickRead\r | |
46 | and EfiSmbusQuickWrite. Length is outside the range of valid\r | |
47 | values.\r | |
48 | @retval EFI_UNSUPPORTED The SMBus operation or PEC is not supported.\r | |
49 | @retval EFI_BUFFER_TOO_SMALL Buffer is not sufficient for this operation.\r | |
