2025-11-18platform/x86: asus-wmi: deprecate bios featuresLuke D. Jones
With the existence of the asus-armoury module the attributes no longer need to live under the /sys/devices/platform/asus-nb-wmi/ path. Deprecate all those that were implemented in asus-bioscfg with the goal of removing them fully in the next LTS cycle. Signed-off-by: Denis Benato <denis.benato@linux.dev> Signed-off-by: Luke D.

2025-11-14platform/chrome: sensorhub: Support devices without FIFO_INT_ENABLEDiogo Ivo
Some devices (such as Smaug) report having MOTION_SENSE_FIFO but do not support controlling the behaviour of the FIFO interrupt via the FIFO_INT_ENABLE command and in these cases the interrupt is always enabled. However, currently the code assumes that if MOTION_SENSE_FIFO is supported then so is FIFO_INT_ENABLE, and when it tries to enable the interrupt via this command and an unsupported device reports a failure it then propagates this into failing the sensors probe. Interpret the return value -EINVAL as a device where FIFO_INT_ENABLE is not present and the interrupt is always enabled.

2025-11-12platform/x86: asus-armoury: move existing tunings to asus-armoury moduleLuke D. Jones
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.

2025-11-10platform/x86: msi-wmi-platform: Fix typo in WMI GUIDArmin Wolf
The WMI driver core only supports GUID strings containing only uppercase characters, however the GUID string used by the msi-wmi-platform driver contains a single lowercase character. This prevents the WMI driver core from matching said driver to its WMI device. Fix this by turning the lowercase character into a uppercase character. Also update the WMI driver development guide to warn about this.

2025-11-10platform/x86: msi-wmi-platform: Only load on MSI devicesArmin Wolf
It turns out that the GUID used by the msi-wmi-platform driver (ABBC0F60-8EA1-11D1-00A0-C90629100000) is not unique, but was instead copied from the WIndows Driver Samples. This means that this driver could load on devices from other manufacturers that also copied this GUID, potentially causing hardware errors. Prevent this by only loading on devices whitelisted via DMI. The DMI matches where taken from the msi-ec driver.

The newer HP Omen laptops, such as Omen 16-wf1xxx, use the same WMI-based thermal profile interface as Victus 16-r1000 and 16-s1000 models. Add the DMI board name "8C78" to the victus_s_thermal_profile_boards list to enable proper fan and thermal mode control. Tested on: HP Omen 16-wf1xxx (board 8C78) Result: * Fan RPMs are readable * echo 0 | sudo tee /sys/devices/platform/hp-wmi/hwmon/*/pwm1_enable allows the fans to run on max RPM.

HONOR MagicBook X16/X14 models produced in 2025 cannot use the Print Screen and YOYO keys properly, with the system reporting them as unknown key presses (codes: 0x028b and 0x028e).

2025-10-30platform/x86: acer-wmi: Fix setting of fan behaviorArmin Wolf
After studying the linuwu_sense driver (https://github.com/0x7375646F/Linuwu-Sense) i was able to understand the meaning of the SetGamingFanBehavior() WMI method: - the first 16-bit are a bitmap of all fans affected by a fan behavior change request. - the next 8 bits contain four fan mode fields (2-bit), each being associated with a bit inside the fan bitmap. There are three fan modes: auto, turbo and custom. Use this newfound knowledge to fix the turbo fan handling by setting the correct bits before calling SetGamingFanBehavior(). Also check the result of the WMI method call and return an error should the ACPI firmware signal failure.

2025-10-28platform/x86: int3472: Fix double free of GPIO device during unregisterQiu Wenbo
regulator_unregister() already frees the associated GPIO device. On ThinkPad X9 (Lunar Lake), this causes a double free issue that leads to random failures when other drivers (typically Intel THC) attempt to allocate interrupts. The root cause is that the reference count of the pinctrl_intel_platform module unexpectedly drops to zero when this driver defers its probe. This behavior can also be reproduced by unloading the module directly. Fix the issue by removing the redundant release of the GPIO device during regulator unregistration.
