97 The SMBus controller is function 3 in device 1f. Class 0c05 is SMBus Serial
101 SMBus controller.

119 The 82801DB (ICH4) and later chips support several SMBus 2.0 features.
128 Hidden ICH SMBus
132 SMBus device at 00:1f.3 in lspci, and you can't figure out any way in the
138 SMBus was hidden on purpose because it'll be driven by ACPI. If the
140 don't try to unhide the ICH SMBus. Even if i2c-scmi doesn't work, you
141 better make sure that the SMBus isn't used by the ACPI code. Try loading
144 accessing the SMBus and it's safer not to unhide it. Only once you are
145 certain that ACPI isn't using the SMBus, you can attempt to unhide it.
147 In order to unhide the SMBus, we need to change the value of a PCI
150 function asus_hides_smbus_hostbridge.) If the SMBus device is missing,
151 and you think there's something interesting on the SMBus (e.g. a
169 that the unhidden SMBus doesn't conflict with e.g. ACPI.
171 If it works, proves useful (i.e. there are usable chips on the SMBus)
176 temporarily unhide the SMBus without having to patch and recompile your
178 anything interesting on your hidden ICH SMBus.
