2025-02-24platform/x86: thinkpad_acpi: Move subdriver initialization to ↵Kurt Borja
tpacpi_pdriver's probe. It was reported that if subdrivers assigned devres resources inside ibm_init_struct's .init callbacks, driver binding would fail with the following error message: platform thinkpad_acpi: Resources present before probing Let the driver core manage the lifetimes of the subdrivers and children devices, by initializing them inside tpacpi_driver's .probe callback. This is appropriate because these subdrivers usually expose sysfs groups and the driver core manages this automatically to avoid races. One immediate benefit of this, is that we are now able to use devres inside .init subdriver callbacks. platform_create_bundle is specifically used because it makes the driver's probe type synchronous and returns an ERR_PTR if attachment failed. Additionally, to make error handling simpler, allocate the input device using devm_input_allocate_device().

2025-02-24platform/x86: wmi: Call WCxx methods when setting data blocksArmin Wolf
After performing some tests with a custom SSDT table available at https://github.com/Wer-Wolf/acpi-wmi-ssdt i found out that Windows also enables data block collection even when the data block is being set. Emulate this behaviour to avoid confusing the ACPI firmware. The bus-based API already implements this behaviour, so only the legacy GUID-based API needs to be changed.

2025-02-24platform/x86: wmi: Rework WCxx/WExx ACPI method handlingArmin Wolf
The handling of the WExx ACPI methods used for enabling and disabling WMI events has multiple flaws: - the ACPI methods are called even when the WMI device has not been marked as expensive. - WExx ACPI methods might be called for inappropriate WMI devices. - the error code AE_NOT_FOUND is treated as success. The handling of the WCxx ACPI methods used for enabling and disabling WMI data blocks is also flawed: - WMI data blocks are enabled and disabled for every single "query" operation. This is racy and inefficient. Unify the handling of both ACPI methods by introducing a common helper function for enabling and disabling WMI devices. Also enable/disable WMI data blocks during probe/remove and shutdown to match the handling of WMI events. Legacy GUID-based functions still have to enable/disable the WMI device manually and thus still suffer from a potential race condition. Since those functions are deprecated and suffer from various other flaws this issue is purposefully not fixed.

2025-02-24platform/x86: wmi: Use devres to disable the WMI deviceArmin Wolf
Use devm_add_action_or_reset() to disable the WMI device instead of manually calling wmi_method_enable() to prepare for future changes inside the WMI data block handlign code. The reason for this is that we have to make sure that all devres-managed resources are released first because some might still want to access the underlying WMI device. Because devres-managed resources are not released during shutdown we still have to manually disable the WMI device in this case.

This error is seen in the kernel logs, and the various tpacpi entries are not created: [ 7550.642171] platform thinkpad_acpi: Resources present before probing This happens because devm_platform_profile_register() is called before tpacpi_pdev probes (thanks to Kurt Borja for identifying the root cause).

Split thermal features into a new DMI table to support upcoming file split. While at it: Rename quirk_entry -> alienfx_quirks, Rename quirks -> alienfx and change hdmi_mux, amplifier and deepslp types to bool, because they are already being implicitly used as bools.

2025-02-10platform/x86: alienware-wmi: Refactor LED control methodsKurt Borja
Both WMI devices handled by this module specify a distinct interface for LED control. Previously this module handled this by dynamically adapting arguments passed to wmi_evaluate_method() based on the `interface` global variable. To avoid the use of global variables, and enable the migration to non-deprecated WMI methods, let the WMI drivers define upd_led and upd_brightness operations, which completely replace alienware_update_led() and wmax_brightness(). Also define alienware_wmi_command(), which serves as a wrapper for wmidev_evaluate_method(). This new method is very similar to alienware_wmax_command() but is WMI device agnostic.

2025-02-10platform/x86: alienware-wmi: Add WMI DriversKurt Borja
Add WMI drivers for LEGACY and WMAX devices. This involves moving the platform device registration to a helper function that is now called from the driver's preferred WMI device driver probe. In the case of the WMAX this is done only if `!quirks->thermal` because the newer WMAX interface doesn't support any of the LED features of this driver. This also eliminates the need to check for `quirks->num_zones > 0` inside alienfx_probe(). Only one WMI driver is registered on module initialization to prevent registering a duplicate platform device. Additionally, create_thermal_profile() now takes wmi_device * instead of platform_device *.

Add a state container for the "alienware-wmi" platform device and initialize it on the new alienfx_probe(). Migrate all LED control functions to use this state container to support upcoming file split. Additionally move the led_classdev registration to the platform driver probe and make it device managed. Drop alienware_zone_init() and alienware_zone_exit() because they are no longer needed and mimic the `quirks->num_zone > 0` check by failing the platform device probe.
