99 The SMBus controller is function 3 in device 1f. Class 0c05 is SMBus Serial
103 SMBus controller.

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