Support Gigabyte B550M AORUS ELITE

[s-kostyuk]

B550M AORUS ELITE (v1.3) uses the IT8689 super I/O chip:

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no):
Probing for Super-I/O at 0x2e/0x2f
Trying family `ITE'...                                      Yes
Found unknown chip with ID 0x8689

The WMI driver loads and populates the hwmon interface with force-load=1:

Talking about fans - I managed to read the RPM values using the frankcrawford/it87 DKMS driver and acpi_enforce_resources=lax in the kernel boot parameters. I have no idea about the fan readout support via WMI. Probably it is supported, but not documented, since I can control the fans via a proprietary tool from Gigabyte on Windows.

Thanks for the report!

I won't do anything about it right now, as beginning with 6.5 the whole allowlist and force_load will completely go away.
So force_load=1 will effectively will be the default.
Unfortunately in the meantime we can't add new hardware IDs, so it will be a bit annoying during the transition phase.

Unfortunately anything involving acpi_enforce_resources=lax is a complete no-go for upstream defaults.

It is fine. I am using the old Ubuntu 5.19 kernel anyway, so will resort to the force_load=1 workaround in modprobe.d.

I understand that. What I am saying is that this option is available for experimentation. Whether we do any experiments with it is a separate question.

Thank you.

If someone figures out how to change RPM values via WMI this would absolutely be a candidate for this driver.
I was not able to do so far.
