2026-01-20platform/x86: hp-bioscfg: Fix automatic module loadingMario Limonciello
hp-bioscfg has a MODULE_DEVICE_TABLE with a GUID in it that looks plausible, but the module doesn't automatically load on applicable systems. This is because the GUID has some lower case characters and so it doesn't match the modalias during boot. Update the GUIDs to be all uppercase.

2026-01-20platform/x86: hp-bioscfg: Fix kernel panic in GET_INSTANCE_ID macroMario Limonciello
The GET_INSTANCE_ID macro that caused a kernel panic when accessing sysfs attributes: 1. Off-by-one error: The loop condition used '<=' instead of '<', causing access beyond array bounds. Since array indices are 0-based and go from 0 to instances_count-1, the loop should use '<'. 2. Missing NULL check: The code dereferenced attr_name_kobj->name without checking if attr_name_kobj was NULL, causing a null pointer dereference in min_length_show() and other attribute show functions. The panic occurred when fwupd tried to read BIOS configuration attributes: Oops: general protection fault [#1] SMP KASAN NOPTI KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007] RIP: 0010:min_length_show+0xcf/0x1d0 [hp_bioscfg] Add a NULL check for attr_name_kobj before dereferencing and corrects the loop boundary to match the pattern used elsewhere in the driver.

2026-01-20platform/wmi: Introduce marshalling supportArmin Wolf
The Windows WMI-ACPI driver likely uses wmilib [1] to interact with the WMI service in userspace. Said library uses plain byte buffers for exchanging data, so the WMI-ACPI driver has to convert between those byte buffers and ACPI objects returned by the ACPI firmware. The format of the byte buffer is publicly documented [2], and after some reverse eingineering of the WMI-ACPI driver using a set of custom ACPI tables, the following conversion rules have been discovered: - ACPI integers are always converted into a uint32 - ACPI strings are converted into special WMI strings - ACPI buffers are copied as-is - ACPI packages are unpacked Extend the ACPI-WMI driver to also perform this kind of marshalling for WMI data blocks, methods and events. Doing so gives us a number of benefits: - WMI drivers are not restricted to a fixed set of supported ACPI data types anymore, see dell-wmi-aio (integer vs buffer) and hp-wmi-sensors (string vs buffer) - correct marshalling of WMI strings when data blocks are marked as requiring ACPI strings instead of ACPI buffers - development of WMI drivers without having to understand ACPI This eventually should result in better compatibility with some ACPI firmware implementations and in simpler WMI drivers. There are however some differences between the original Windows driver and the ACPI-WMI driver when it comes to ACPI object conversions: - the Windows driver copies internal _ACPI_METHOD_ARGUMENT_V1 data structures into the output buffer when encountering nested ACPI packages. This is very likely an error inside the driver itself, so we do not support nested ACPI packages. - when converting WMI strings (UTF-16LE) into ACPI strings (ASCII), the Windows driver replaces non-ascii characters (ä -> a, & -> ?) instead of returning an error. This behavior is not documented anywhere and might lead to severe errors in some cases (like setting BIOS passwords over WMI), so we simply return an error. As the current bus-based WMI API is based on ACPI buffers, a new API is necessary. The legacy GUID-based WMI API is not extended to support marshalling, as WMI drivers using said API are expected to move to the bus-based WMI API in the future.

2026-01-15platform/x86: hp-wmi: fix platform profile values for Omen 16-wf1xxxKrishna Chomal
HP Omen 16-wf1xxx (board ID 8C78) currently sends the incorrect Victus-specific thermal profile values via WMI, leading to a logical inconsistency when switching between platform profiles. The driver currently uses Victus S values: 0x00 => Balanced / Low-Power 0x01 => Performance However, Omen Gaming Hub logs / EC register inspection on Windows shows that this board is intended to use: 0x30 => Balanced / Low-Power 0x31 => Performance This patch corrects the thermal profile command values to match the values observed from Omen Gaming Hub logs. The performance benchmarks and peak power draw (from both CPU and GPU) show no observable change with this correction (suggesting that the firmware is currently tolerant of the incorrect values). However sending the correct values prevents potential regressions after future firmware updates. Refactor victus_s_thermal_profile_boards from a list of strings to a dmi_system_id table and move the lookup to module init. The new struct thermal_profile_params is used to store board-specific WMI parameters, allowing the driver to cache these values in a static pointer. This avoids repeated DMI string comparisons and allows marking of DMI table as __initconst. Testing on HP Omen 16-wf1xxx (board 8C78) confirmed WMI codes 0x30/0x31 are now sent, resolving the logical inconsistency and ensuring the value visible in EC registers match the Windows state for this profile.

2026-01-15platform/x86: hp-wmi: implement fan keep-aliveKrishna Chomal
The firmware on some HP laptops automatically reverts the fan speed control to "Auto" mode after a 120 second timeout window. To ensure that the user-selected fan profile (Max/Manual) persists, implement a keep-alive mechanism that periodically refreshes the fan mode trigger before the timeout occurs. - Introduce a delayed workqueue to trigger the fan mode refresh every 90 seconds, ensuring the system maintains the correct fan mode setting. - Integrate the refresh mechanism into hp_wmi_apply_fan_settings() to start, update or cancel the keep-alive process based on the current fan mode. This ensures that the driver stays in sync with the hardware.

2026-01-15platform/x86: hp-wmi: add manual fan control for Victus S modelsKrishna Chomal
Add manual fan speed control and PWM reporting for HP Victus S-series laptops. While HPWMI_FAN_SPEED_SET_QUERY was previously added to reset max fan mode, it is actually capable of individual fan control. This patch implements hp_wmi_fan_speed_set() to allow manual control and hides PWM inputs for non-Victus devices as the query is Victus specific. The existing hp_wmi_fan_speed_max_get() query is unreliable on Victus S firmware, often incorrectly reporting "Auto" mode even when "Max" is active. To resolve this synchronization issue, move state tracking to a per-device private context and apply "Auto" mode during driver initialization to ensure a consistent starting point. Refactor hp_wmi_apply_fan_settings() to use an intermediate ret variable. This prepares the switch block for keep-alive logic being added in a later patch, avoiding the need for duplicated mode check.

2026-01-08platform/chrome: cros_hps_i2c: Discard pm_runtime_put() return valueRafael J. Wysocki
Passing pm_runtime_put() return value to the callers is not particularly useful. Returning an error code from pm_runtime_put() merely means that it has not queued up a work item to check whether or not the device can be suspended and there are many perfectly valid situations in which that can happen, like after writing "on" to the devices' runtime PM "control" attribute in sysfs for one example. It also happens when the kernel is configured with CONFIG_PM unset. Accordingly, update hps_release() to simply discard the return value of pm_runtime_put() and always return success to the caller. This will facilitate a planned change of the pm_runtime_put() return type to void in the future. Signed-off-by: Rafael J.

The PMT feature probe creates a child device with device_create(). If device creation fail, the code pass priv->dev (which is an ERR_PTR) to dev_err_probe(), which is not a valid device pointer. This patch change the dev_err_probe() call to use the parent auxiliary device (&auxdev->dev) and update the error message to reference the parent device name. It ensure correct error reporting and avoid passing an invalid device pointer.

2025-12-29platform/x86: hp-bioscfg: Fix out-of-bounds array access in ACPI package parsingJunrui Luo
The hp_populate_*_elements_from_package() functions in the hp-bioscfg driver contain out-of-bounds array access vulnerabilities. These functions parse ACPI packages into internal data structures using a for loop with index variable 'elem' that iterates through enum_obj/integer_obj/order_obj/password_obj/string_obj arrays. When processing multi-element fields like PREREQUISITES and ENUM_POSSIBLE_VALUES, these functions read multiple consecutive array elements using expressions like 'enum_obj[elem + reqs]' and 'enum_obj[elem + pos_values]' within nested loops. The bug is that the bounds check only validated elem, but did not consider the additional offset when accessing elem + reqs or elem + pos_values. The fix changes the bounds check to validate the actual accessed index.
