ACPISMBUS(4) | NetBSD Kernel Interfaces Manual | ACPISMBUS(4) |
The SMBus CMI protocol defines a method to provide a list of devices on an i2c bus segment and their addresses. The acpismbus driver makes no attempt to retrieve or process this device list.
There is currently no way to determine if the i2c controller managed by an instance of the ACPI SMBus CMI can also be accessed using a native device driver. Therefore, the acpismbus driver should not be enabled by default. If both a native driver and the acpismbus driver attempt to access the same i2c bus segment, the results are undefined.
