Notes:
The driver provides a Microsoft IO Control interface. This allows the SMBus driver to easily interface under the existing Microsoft drivers without any re-work. As previously stated, the driver allows multiple SMBus branches to be operational within the system. Each segment is registered under ACPI and reports to the system OS using the SMBus information control method. Additionally the characteristics each fixed slave address SMBus device attached to those segments is also available via the SMBus information control method. The driver supports all aspects of SMBus including managing the Alert function. If an SMBus device utilizes the Alert Feature, applications registering in ACPI for this type of notification can receive alert information from multiple branches and multiple devices in an orderly and deterministic way.
