platform/x86: bitland-mifs-wmi: Add new Bitland MIFS WMI driver

2026-03-24T13:03:09+00:00

Add a new driver for Bitland laptops that utilize the MIFS (MiInterface) WMI interface. The driver implements several features through the WMI interface: - Platform Profile: Supports "Quiet", "Balanced", "Performance", and "Full Speed" modes. The "Full Speed" mode is intelligently restricted based on the AC adapter type (requires DC power, not supported on USB-C charging) as required by the hardware. - Hwmon: Provides monitoring for CPU, GPU, and System fan speeds, as well as CPU temperature sensors. - Keyboard Backlight: Integrated with the LED class device for brightness control and provides sysfs attributes for keyboard modes (cyclic, fixed, etc.). - GPU Mode: Allows switching between Hybrid, Discrete, and UMA graphics modes via sysfs. - Hotkeys: Handles WMI events for system hotkeys (Calculator, Browser, App launch) using sparse keymaps and reports status changes for Airplane mode, Touchpad, and CapsLock. - Fan Boost: Provides a sysfs interface to force fans to maximum speed. The driver registers two WMI GUIDs: - B60BFB48-3E5B-49E4-A0E9-8CFFE1B3434B: Control methods - 46C93E13-EE9B-4262-8488-563BCA757FEF: Event notifications Reviewed-by: Armin Wolf Signed-off-by: Mingyou Chen Link: https://patch.msgid.link/20260323132218.444383-1-qby140326@gmail.com Reviewed-by: Ilpo Järvinen Signed-off-by: Ilpo Järvinen

platform/x86: ayaneo-ec: Add Ayaneo Embedded Controller platform driver

2025-11-21T15:36:12+00:00

Recent Ayaneo devices feature an ACPI mapped Embedded Controller (EC) with standard addresses across models that provides access to fan speed, fan control, battery charge limits, and controller power controls. Introduce a new driver stub that will handle these driver features.

platform/x86: asus-armoury: move existing tunings to asus-armoury module

2025-11-12T12:21:08+00:00

The fw_attributes_class provides a much cleaner interface to all of the attributes introduced to asus-wmi. This patch moves all of these extra attributes over to fw_attributes_class, and shifts the bulk of these definitions to a new kernel module to reduce the clutter of asus-wmi with the intention of deprecating the asus-wmi attributes in future. The work applies only to WMI methods which don't have a clearly defined place within the sysfs and as a result ended up lumped together in /sys/devices/platform/asus-nb-wmi/ with no standard API. Where possible the fw attrs now implement defaults, min, max, scalar, choices, etc. As en example dgpu_disable becomes: /sys/class/firmware-attributes/asus-armoury/attributes/dgpu_disable/ ├── current_value ├── display_name ├── possible_values └── type as do other attributes.

platform/x86: Add Uniwill laptop driver

2025-11-10T10:04:34+00:00

Add a new driver for Uniwill laptops. The driver uses a ACPI interface to talk with the embedded controller, but relies on a ACPI WMI interface for receiving event notifications. The driver is reverse-engineered based on the following information: - OEM software from intel - https://github.com/pobrn/qc71_laptop - https://gitlab.com/tuxedocomputers/development/packages/tuxedo-drivers - https://github.com/tuxedocomputers/tuxedo-control-center The underlying EC supports various features, including hwmon sensors, battery charge limiting, a RGB lightbar and keyboard-related controls.

platform/x86: Fix initialization order for firmware_attributes_class

2025-07-11T15:52:54+00:00

The think-lmi driver uses the firwmare_attributes_class. But this class is registered after think-lmi, causing the "think-lmi" directory in "/sys/class/firmware-attributes" to be missing when the driver is compiled as builtin.

platform/x86: portwell-ec: Add GPIO and WDT driver for Portwell EC

2025-05-08T14:37:58+00:00

Adds a driver for the ITE Embedded Controller (EC) on Portwell boards. It integrates with the Linux GPIO and watchdog subsystems to provide: - Control/monitoring of up to 8 EC GPIO pins. - Hardware watchdog timer with 1-255 second timeouts. The driver communicates with the EC via I/O port 0xe300 and identifies the hardware by the "PWG" firmware signature. This enables enhanced system management for Portwell embedded/industrial platforms.
