100 The SMBus controller is function 3 in device 1f. Class 0c05 is SMBus Serial
104 SMBus controller.

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