This implementation automatically detects available thermal profiles and GMODE + Game Shift availability, which is a feature of G-Series laptops. Signed-off-by: Kurt Borja --- v7: - Method operations are now clearly listed as separate enums - wmax_thermal_modes are now listed without codes in order to support autodetection, as well as getting and setting thermal profiles cleanly through arrays - Added wmax_mode_to_platform_profile[] - Added struct wmax_u32_args to replace bit mask approach of constructing arguments for wmax methods - create_thermal_profile now autodetects available thermal codes through operation 0x03 of THERMAL_INFORMATION method. These are codes are stored in supported_thermal_profiles[] - thermal_profile_get now uses wmax_mode_to_platform_profile[] instead of switch-case approach - thermal_profile_set now uses supported_thermal_profiles[] instead of switch-case approach - When gmode is autodetected, thermal_profile_set also sets Game Shift status accordingly v6: - Fixed alignment on some function definitions - Fixed braces on if statment - Removed quirk thermal_ustt - Now quirk thermal can take values defined in enum WMAX_THERMAL_TABLE. - Proper removal of thermal_profile --- This refactor was done in order to autodetect available thermal modes efficently through operation 0x03. This new array approach exploits the fact that the first 4 bits of every thermal code are consecutive from 0 to 9, however next 4 bits are not consecutive (available thermal codes are documented in patch 4/4) so full codes are dynamically probed based on rules found in is_wmax_thermal_code(). --- drivers/platform/x86/dell/Kconfig | 1 + drivers/platform/x86/dell/alienware-wmi.c | 282 ++++++++++++++++++++++ 2 files changed, 283 insertions(+) diff --git a/drivers/platform/x86/dell/Kconfig b/drivers/platform/x86/dell/Kconfig index 68a49788a..b06d634cd 100644 --- a/drivers/platform/x86/dell/Kconfig +++ b/drivers/platform/x86/dell/Kconfig @@ -21,6 +21,7 @@ config ALIENWARE_WMI depends on LEDS_CLASS depends on NEW_LEDS depends on ACPI_WMI + select ACPI_PLATFORM_PROFILE help This is a driver for controlling Alienware BIOS driven features.

SPDX-License-Identifier: GPL-2.0-or-later + +============================================== +Dell AWCC WMI interface driver (alienware-wmi) +============================================== + +Introduction +============ + +The WMI device WMAX has been implemented for many Alienware and Dell's G-Series +models. Throughout these models, two implementations have been identified. The +first one, used by older systems, deals with HDMI, brightness, RGB, amplifier +and deep sleep control. The second one used by newer systems deals primarily +with thermal, overclocking, and GPIO control. + +It is suspected that the latter is used by Alienware Command Center (AWCC) to +manage manufacturer predefined thermal profiles. The alienware-wmi driver +exposes Thermal_Information and Thermal_Control methods through the Platform +Profile API to mimic AWCC's behavior. + +This newer interface, named AWCCMethodFunction has been reverse engineered, as +Dell has not provided any official documentation. We will try to describe to the +best of our ability its discovered inner workings. + +.. note:: + The following method description may be incomplete and some operations have + different implementations between devices. + +WMI interface description +------------------------- + +The WMI interface description can be decoded from the embedded binary MOF (bmof) +data using the `bmfdec `_ utility: + +:: + + [WMI, Dynamic, Provider("WmiProv"), Locale("MS\\0x409"), Description("WMI Function"), guid("{A70591CE-A997-11DA-B012-B622A1EF5492}")] + class AWCCWmiMethodFunction { + [key, read] string InstanceName; + [read] boolean Active; + + [WmiMethodId(13), Implemented, read, write, Description("Return Overclocking Report.")] void Return_OverclockingReport([out] uint32 argr); + [WmiMethodId(14), Implemented, read, write, Description("Set OCUIBIOS Control.")] void Set_OCUIBIOSControl([in] uint32 arg2, [out] uint32 argr); + [WmiMethodId(15), Implemented, read, write, Description("Clear OC FailSafe Flag.")] void Clear_OCFailSafeFlag([out] uint32 argr); + [WmiMethodId(19), Implemented, read, write, Description("Get Fan Sensors.")] void GetFanSensors([in] uint32 arg2, [out] uint32 argr); + [WmiMethodId(20), Implemented, read, write, Description("Thermal Information.")] void Thermal_Information([in] uint32 arg2, [out] uint32 argr); + [WmiMethodId(21), Implemented, read, write, Description("Thermal Control.")] void Thermal_Control([in] uint32 arg2, [out] uint32 argr); + [WmiMethodId(23), Implemented, read, write, Description("MemoryOCControl.")] void MemoryOCControl([in] uint32 arg2, [out] uint32 argr); + [WmiMethodId(26), Implemented, read, write, Description("System Information.")] void SystemInformation([in] uint32 arg2, [out] uint32 argr); + [WmiMethodId(28), Implemented, read, write, Description("Power Information.")] void PowerInformation([in] uint32 arg2, [out] uint32 argr); + [WmiMethodId(32), Implemented, read, write, Description("FW Update GPIO toggle.")] void FWUpdateGPIOtoggle([in] uint32 arg2, [out] uint32 argr); + [WmiMethodId(33), Implemented, read, write, Description("Read Total of GPIOs.")] void ReadTotalofGPIOs([out] uint32 argr); + [WmiMethodId(34), Implemented, read, write, Description("Read GPIO pin Status.")] void ReadGPIOpPinStatus([in] uint32 arg2, [out] uint32 argr); + [WmiMethodId(35), Implemented, read, write, Description("Read Chassis Color.")] void ReadChassisColor([out] uint32 argr); + [WmiMethodId(36), Implemented, read, write, Description("Read Platform Properties.")] void ReadPlatformProperties([out] uint32 argr); + [WmiMethodId(37), Implemented, read, write, Description("Game Shift Status.")] void GameShiftStatus([in] uint32 arg2, [out] uint32 argr); + [WmiMethodId(128), Implemented, read, write, Description("Caldera SW installation.")] void CalderaSWInstallation([out] uint32 argr); + [WmiMethodId(129), Implemented, read, write, Description("Caldera SW is released.")] void CalderaSWReleased([out] uint32 argr); + [WmiMethodId(130), Implemented, read, write, Description("Caldera Connection Status.")] void CalderaConnectionStatus([in] uint32 arg2, [out] uint32 argr); + [WmiMethodId(131), Implemented, read, write, Description("Surprise Unplugged Flag Status.")] void SurpriseUnpluggedFlagStatus([out] uint32 argr); + [WmiMethodId(132), Implemented, read, write, Description("Clear Surprise Unplugged Flag.")] void ClearSurpriseUnpluggedFlag([out] uint32 argr); + [WmiMethodId(133), Implemented, read, write, Description("Cancel Undock Request.")] void CancelUndockRequest([out] uint32 argr); + [WmiMethodId(135), Implemented, read, write, Description("Devices in Caldera.")] void DevicesInCaldera([in] uint32 arg2, [out] uint32 argr); + [WmiMethodId(136), Implemented, read, write, Description("Notify BIOS for SW ready to disconnect Caldera.")] void NotifyBIOSForSWReadyToDisconnectCaldera([out] uint32 argr); + [WmiMethodId(160), Implemented, read, write, Description("Tobii SW installation.")] void TobiiSWinstallation([out] uint32 argr); + [WmiMethodId(161), Implemented, read, write, Description("Tobii SW Released.")] void TobiiSWReleased([out] uint32 argr); + [WmiMethodId(162), Implemented, read, write, Description("Tobii Camera Power Reset.")] void TobiiCameraPowerReset([out] uint32 argr); + [WmiMethodId(163), Implemented, read, write, Description("Tobii Camera Power On.")] void TobiiCameraPowerOn([out] uint32 argr); + [WmiMethodId(164), Implemented, read, write, Description("Tobii Camera Power Off.")] void TobiiCameraPowerOff([out] uint32 argr); + }; + +Some of these methods get quite intricate so we will describe them using +pseudo-code that vaguely resembles the original ASL code. + +Methods not described in the following document have unknown behavior. + +Argument Structure +------------------ + +All input arguments have type **uint32** and their structure is very similar +between methods.
