2025-08-29platform/x86/intel: power-domains: Use topology_logical_package_id() for ↵David Arcari
package ID Currently, tpmi_get_logical_id() calls topology_physical_package_id() to set the pkg_id of the info structure. Since some VM hosts assign non contiguous package IDs, topology_physical_package_id() can return a larger value than topology_max_packages(). This will result in an invalid reference into tpmi_power_domain_mask[] as that is allocatead based on topology_max_packages() as the maximum package ID.

2025-08-28platform/x86: acer-wmi: Stop using ACPI bitmap for platform profile choicesArmin Wolf
It turns out that the platform firmware on some models does not return valid data when reading the bitmap of supported platform profiles. This prevents the driver from loading on said models, even when the platform profile interface itself works. Fix this by stop using said bitmap until we have figured out how the OEM software itself detects available platform profiles.

2025-08-28platform/x86: hp-wmi: Add support for Fn+P hotkeyEdip Hazuri
Add support for the Fn+P hotkey found on newer HP Victus (and probably newer Omen) laptops. This hotkey is intended for use with Omen Gaming Hub to change the performance profile (see [1]). Pressing Fn+P under linux produced the following warning in dmesg: > hp_wmi: Unknown event_id - 27 - 0x7 Implemented a handling for this event so that the hotkey cycles between the platform profiles when triggered. Tested on Victus 16-s1011nt (9Z791EA, MB 8C9C).

2025-08-28platform/x86: asus-wmi: Fix racy registrationsTakashi Iwai
asus_wmi_register_driver() may be called from multiple drivers concurrently, which can lead to the racy list operations, eventually corrupting the memory and hitting Oops on some ASUS machines. Also, the error handling is missing, and it forgot to unregister ACPI lps0 dev ops in the error case. This patch covers those issues by introducing a simple mutex at acpi_wmi_register_driver() & *_unregister_driver, and adding the proper call of asus_s2idle_check_unregister() in the error path.

2025-08-25platform/x86: asus-wmi: Fix ROG button mapping, tablet mode on ASUS ROG Z13Antheas Kapenekakis
On commit 9286dfd5735b ("platform/x86: asus-wmi: Fix spurious rfkill on UX8406MA"), Mathieu adds a quirk for the Zenbook Duo to ignore the code 0x5f (WLAN button disable). On that laptop, this code is triggered when the device keyboard is attached. On the ASUS ROG Z13 2025, this code is triggered when pressing the side button of the device, which is used to open Armoury Crate in Windows. As this is becoming a pattern, where newer Asus laptops use this keycode for emitting events, let's convert the wlan ignore quirk to instead allow emitting codes, so that userspace programs can listen to it and so that it does not interfere with the rfkill state. With this patch, the Z13 wil emit KEY_PROG3 and the Duo will remain unchanged and emit no event. While at it, add a quirk for the Z13 to switch into tablet mode when removing the keyboard.

2025-08-25platform/x86: asus-wmi: Remove extra keys from ignore_key_wlan quirkAntheas Kapenekakis
Currently, the ignore_key_wlan quirk applies to keycodes 0x5D, 0x5E, and 0x5F. However, the relevant code for the Asus Zenbook Duo is only 0x5F. Since this code is emitted by other Asus devices, such as from the Z13 for its ROG button, remove the extra codes before expanding the quirk. For the Duo devices, which are the only ones that use this quirk, there should be no effect.

2025-08-12platform/x86/amd: pmc: Drop SMU F/W match for CezanneMario Limonciello
Chris reported that even on a BIOS that has a new enough SMU F/W version there is still a spurious IRQ1. Although the solution was added to SMU F/W 64.66.0 it turns out there needs to be a matching SBIOS change to activate it. Thus Linux shouldn't be avoiding the IRQ1 workaround on newer SMU F/W because there is no indication the BIOS change is in place. Drop the match for 64.66.0+ and instead match all RN/CZN/BRC (they all share same SMU F/W). Adjust the quirk infrastructure to allow quirking the workaround on or off and also adjust existing quirks to match properly. Unfortunately this may cause some systems that did have the SBIOS change in place to regress in keyboard wakeup but we don't have a way to know. If a user reports a keyboard wakeup regression they can run with amd_pmc.disable_workarounds=1 to deactivate the workaround and share DMI data so that their system can be quirked not to use the workaround in the upstream kernel.

2025-08-12platform/x86: dell-smbios-wmi: Stop touching WMI device IDArmin Wolf
The Dell SMBIOS driver uses the "id" field inside struct device for prioritizing the WMI backend over the SMM backend. Because of this the WMI backend modifies the "id" field of the underlying WMI device. However the WMI core itself uses wdev->dev.id internally to track device IDs, so modifying this value will result in a resource leak. Fix this by not using the "id" field inside struct device for SMBIOS prioritization. Instead extend struct smbios_device with a separate "priority" field. Tested on a Dell Inspiron 3505.

2025-07-09platform/x86/amd/hsmp: Enhance the print messages to prevent confusionSuma Hegde
When the HSMP ACPI device is present, loading the amd_hsmp.ko module incorrectly displays the message "HSMP is not supported on Family:%x model:%x\n" despite being supported by the hsmp_acpi.ko module, leading to confusion. To address this issue, relocate the acpi_dev_present() check to the beginning of the hsmp_plt_init() and revise the print message to better reflect the current support status. Additionally, add more error messages in the error paths and debug messages to indicate successful probing for both hsmp_acpi.ko and amd_hsmp.ko modules.

2025-07-09lenovo-wmi-hotkey: Avoid triggering error -5 due to missing mute LEDJackie Dong
Not all of Lenovo non-ThinkPad devices support both mic mute LED (on F4) and audio mute LED (on F1). Some of them only support one mute LED, some of them don't have any mute LEDs. If any of the mute LEDs is missing, the driver reports error -5. Check if the device supports a mute LED or not. Do not trigger error -5 message from missing a mute LED if it is not supported on the device.
