Executes an SMBus operation to an SMBus controller.
@param This A pointer to the EFI_PEI_SMBUS2_PPI instance.
@param SlaveAddress The SMBUS hardware address to which the SMBUS device is preassigned or
allocated.
@param Command This command is transmitted by the SMBus host controller to the SMBus slave
device and the interpretation is SMBus slave device specific.
It can mean the offset to a list of functions inside
an SMBus slave device. Not all operations or slave devices support
this command's registers.
@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 System Management Bus (SMBus)
Specification and is not related to UEFI.
@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.
The maximum number of bytes can be revision specific and operation specific.
This parameter 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 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.
