* platform/x86: wmi: Add MSI WMI Platform driverArmin Wolf2024-04-291-0/+194
| | | | | | | | | | | | | | | | | | | | | | Add a new driver for the MSI WMI Platform interface. The underlying ACPI WMI interface supports many features, but so far only reading of fan speed sensors is implemented. The driver was reverse-engineered based on a user request to the lm-sensors project, see the github issue for details. The ACPI WMI interface used by this driver seems to use the same embedded controller interface as the msi-ec driver, but supports automatic discovery of supported machines without relying on a DMI whitelist. The driver was tested by the user who created the github issue.

* platform/x86: wmi: Add driver development guideArmin Wolf2024-04-082-0/+179
| | | | | | | | | | | | | | | | | | | Since 2010, an LWN article covering WMI drivers exists: https://lwn.net/Articles/391230/ Since the introduction of the modern bus-based interface and other userspace tooling (bmfdec, lswmi, ...), this article is outdated and causes people to still submit new WMI drivers using the deprecated GUID-based interface. Fix this by adding a short guide on how to develop WMI drivers using the modern bus-based interface.

| | | | | | | | | | | | | | The WMI interface used by the dell-wmi-ddv driver contains many methods which are currently unused, making it difficult to document these inside the drivers source code.

* platform/x86: wmi: Add documentationArmin Wolf2023-05-092-0/+114
Add documentation for the WMI subsystem. The documentation describes both the ACPI WMI interface and the driver API for interacting with the WMI driver core. The information regarding the ACPI interface was retrieved from the Ubuntu kernel references and the Windows driver samples available on GitHub. The documentation is supposed to help driver developers writing WMI drivers, as many modern machines designed to run Windows provide an ACPI WMI interface.
