[PATCH v3 1/4] platform/x86: Add lenovo-wmi drivers Documentation

Derek J. Clark
2025-02-25T22:00:52Z

Adds documentation for all new lenovo-wmi drivers.

v3:
- Split documentation into multiple files, one for each parent
driver for the Gamezone and Other Mode WMI interfaces.
- Add MOF data for all parent and child interfaces.
- Remove lenovo-wmi-camera.c driver from v2 documentation.
v2:
- Update description of Custom Profile to include the need to manually
set it.
- Remove all references to Legion hardware.
- Add section for lenovo-wmi-camera.c driver as it follows the same
naming convention.

+Lenovo WMI Interface Gamezone Driver (lenovo-wmi-gamezone)
+==========================================================
+
+Introduction
+============
+The Lenovo WMI gamezone interface is broken up into multiple GUIDs,
+The priamry "Gamezone" GUID provides advanced features such as fan
+profiles and overclocking. It is paired with multiple event GUIDs
+and data block GUIDs that provide context for the various methods.
+
+Gamezone Data
+-------------
+WMI GUID "887B54E3-DDDC-4B2C-8B88-68A26A8835D0"
+
+The Gamezone Data WMI interface provides platform-profile and fan curve
+settings for devices that fall under the "Gaming Series" of Lenovo devices.
+It uses a notifier chain to inform other Lenovo WMI interface drivers of the
+current platform profile when it changes.
+
+The following platform profiles are supported:
+ - low-power
+ - balanced
+ - balanced-performance
+ - performance
+ - custom
+
+Balanced-Perfornance and Performance Profiles
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Some newer Lenovo "Gaming Series" laptops have an "Extreme Mode" profile
+enabled in their BIOS. For these devices, the performance platform profile
+will correspond to the BIOS Extreme Mode, while the balanced-performance
+platform profile will correspond to the BIOS Performance mode. For legacy
+devices, the performance platform prfile will correspond with the BIOS
+Performance mode.
+
+Custom Profile
+~~~~~~~~~~~~~~
+The custom profile represents a hardware mode on Lenovo devices that enables
+user modifications to Package Power Tracking (PPT) and fan curve settings.
+When an attribute exposed by the Other Mode WMI interface is to be modified,
+the Gamezone driver must first be switched to the "custom" profile manually,
+or the setting will have no effect. If another profile is set from the list
+of supported profiles, the BIOS will override any user PPT settings when
+switching to that profile.
+
+Gamezone Thermal Mode Event
+---------------------------
+WMI GUID "D320289E-8FEA-41E0-86F9-911D83151B5F"
+
+The Gamezone Thermal Mode Event interface notifies the system when the platform
+profile has changed, either through the hardware event (Fn+Q for laptops or
+Legion + Y for Go Series), or through the Gamezone WMI interface.
+
+

+Lenovo WMI Interface Other Mode Driver (lenovo-wmi-other)
+===========================================================
+
+Introduction
+============
+Lenovo WMI Other Mode interface is broken up into multiple GUIDs,
+The primary Other Mode interface provides advanced power tuning features
+such as Package Power Tracking (PPT). It is paired with multiple data block
+GUIDs that provide context for the various methods.
+
+
+Other Mode
+------------
+WMI GUID "DC2A8805-3A8C-41BA-A6F7-092E0089CD3B"
+
+The Other Mode WMI interface uses the fw_attributes class to expose
+various WMI attributes provided by the interface in the sysfs. This enables
+CPU and GPU power limit tuning as well as various other attributes for
+devices that fall under the "Gaming Series" of Lenovo devices. Each
+attribute exposed by the Other Mode interface has corresponding
+capability data blocks which allow the driver to probe details about the
+attribute. Each attibute has multiple pages, one for each of the platform
+profiles managed by the Gamezone interface. Attributes are exposed in sysfs
+under the following path:
+
+::
+/sys/class/firmware-attributes/lenovo-wmi-other/attributes/<attribute>/
+
+LENOVO_CAPABILITY_DATA_01
+~~~~~~~~~~~~~~~~~~~~~~~~~
+WMI GUID "7A8F5407-CB67-4D6E-B547-39B3BE018154"
+
+The LENOVO_CAPABILITY_DATA_01 interface provides information on various
+power limits of integrated CPU and GPU components.
+
+The following attributes are supported:
+ - ppt_pl1_spl: Platform Profile Tracking Sustained Power Limit
+ - ppt_pl2_sppt: Platform Profile Tracking Slow Package Power Tracking
+ - ppt_pl3_fppt: Platform Profile Tracking Fast Package Power Tracking
+
+Each attribute has the following properties:
+ - current_value
+ - default_value
+ - display_name
+ - max_value
+ - min_value
+ - scalar_increment
+ - type
+
