Mon, 23 Mar 2026 14:22:18 +0100

platform/x86: bitland-mifs-wmi: Add new Bitland MIFS WMI driverAdd 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 notificationsReviewed-by: Armin Wolf Signed-off-by: Mingyou Chen Link: https://patch.msgid.link/20260323132218.444383-1-qby140326@gmail.comReviewed-by: Ilpo Järvinen Signed-off-by: Ilpo Järvinen List of files: /linux/drivers/platform/x86/Kconfig

platform/x86: asus-armoury: move existing tunings to asus-armoury moduleThe fw_attributes_class provides a much cleaner interface to all of theattributes introduced to asus-wmi. This patch moves all of these extraattributes over to fw_attributes_class, and shifts the bulk of thesedefinitions to a new kernel module to reduce the clutter of asus-wmiwith the intention of deprecating the asus-wmi attributes in future.The work applies only to WMI methods which don't have a clearly definedplace 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└── typeas do other attributes.Co-developed-by: Denis Benato Signed-off-by: Denis Benato Signed-off-by: Luke D.

This means that this drivercould load on devices from other manufacturers that also copied thisGUID, potentially causing hardware errors.Prevent this by only loading on devices whitelisted via DMI.

Tue, 10 Jun 2025 07:55:26 +0200

platform/x86: wmi: Fix WMI device naming issueWhen multiple WMI devices with the same GUID are presentinside a given system, the WMI driver core might fail toregister all of them.Consider the following scenario: WMI devices ([-]): 05901221-D566-11D1-B2F0-00A0C9062910 (on PNP0C14:00) 05901221-D566-11D1-B2F0-00A0C9062910-1 (on PNP0C14:01)If the WMI core driver somehow unbinds from PNP0C14:00, the followingwill happen upon rebinding:1. The WMI driver core counts all registered WMI devices with a GUID of 05901221-D566-11D1-B2F0-00A0C9062910 (count: 1).2. The new WMI device will be named "05901221-D566-11D1-B2F0-00A0C9062910-1" because another device with the same GUID is already registered (on PNP0C14:01).3. The new WMI device cannot be registered due to a name conflict.Use a IDA when building the WMI device name to avoid such namecollisions by ensuring that a given WMI device ID is not reused.Userspace applications using udev for WMI device detection are notimpacted by this change. Additionally userspace applications that dofully support the existing naming scheme are also not impacted. Onlyuserspace applications using hardcoded sysfs paths will break.Introduce a kconfig option for restoring the old naming scheme togive developers time to fix any compatibility issues.Tested on a Asus Prime B650-Plus.Signed-off-by: Armin Wolf Link: https://lore.kernel.org/r/20250610055526.23688-2-W_Armin@gmx.deReviewed-by: Ilpo Järvinen Signed-off-by: Ilpo Järvinen List of files: /linux/drivers/platform/x86/Kconfig
