cc0809b7 - platform/x86: dell-smo8800: Move instantiation of lis3lv02d i2c_client from i2c-i801 to dell-lis3lv02d

Mon, 09 Dec 2024 18:35:55 +0000

platform/x86: dell-smo8800: Move instantiation of lis3lv02d i2c_client from i2c-i801 to dell-lis3lv02dVarious Dell laptops have an lis3lv02d freefall/accelerometer sensor.The lis3lv02d chip has an interrupt line as well as an I2C connection tothe system's main SMBus.The lis3lv02d is described in the ACPI tables by an SMO88xx ACPI device,but the SMO88xx ACPI fwnodes are incomplete and only list an IRQ resource.So far this has been worked around with some SMO88xx specific quirk codein the generic i2c-i801 driver, but it is not necessary to handle the Dellspecific instantiation of i2c_client-s for SMO88xx ACPI devices there.The kernel already instantiates platform_device-s for these with anacpi:SMO88xx modalias. The drivers/platform/x86/dell/dell-smo8800.cdriver binds to this platform device but this only deals withthe interrupt resource. Add a drivers/platform/x86/dell/dell-lis3lv02d.cwhich will matches on the same acpi:SMO88xx modaliases and movethe i2c_client instantiation from the generic i2c-i801 driver there.Moving the i2c_client instantiation has the following advantages:1. This moves the SMO88xx ACPI device quirk handling away from the generici2c-i801 module which is loaded on all Intel x86 machines to a modulewhich will only be loaded when there is an ACPI SMO88xx device.2. This removes the duplication of the SMO88xx ACPI Hardware ID (HID) tablebetween the i2c-i801 and dell-smo8800 drivers.3. This allows extending the quirk handling by adding new code and relatedmodule parameters to the dell-lis3lv02d driver, without needing to modifythe i2c-i801 code.Reviewed-by: Pali Rohár Signed-off-by: Hans de Goede Acked-by: Wolfram Sang Link: https://lore.kernel.org/r/20241209183557.7560-3-hdegoede@redhat.comReviewed-by: Ilpo Järvinen Signed-off-by: Ilpo Järvinen List of files: /linux-6.15/drivers/platform/x86/dell/Kconfig

9f6c4304 - alienware-wmi: added platform profile support

Wed, 30 Oct 2024 00:11:23 +0000

alienware-wmi: added platform profile supportImplements platform profile support for Dell laptops with new WMAX thermalinterface, present on some Alienware X-Series, Alienware M-Series andDell's G-Series laptops. This interface is suspected to be used byAlienware Command Center (AWCC), which is not available for linuxsystems, to manage thermal profiles.This implementation makes use of three WMI methods, namelyTHERMAL_CONTROL, THERMAL_INFORMATION and GAME_SHIFT_STATUS, which takeu32 as input and output arguments. Each method has a set of supportedoperations specified in their respective enums.Not all models with WMAX WMI interface support these methods. Because ofthis, models have to manually declare support through new quirks`thermal` for THERMAL_CONTROL and THERMAL_INFORMATION and `gmode` forGAME_SHIFT_STATUS.Wrappers written for these methods support multiple operations.THERMAL_CONTROL switches thermal modes through operationACTIVATE_PROFILE. Available thermal codes are auto-detected at runtimeand matched against a list of known thermal codes:Thermal Table "User Selectable Thermal Tables" (USTT): BALANCED 0xA0 BALANCED_PERFORMANCE 0xA1 COOL 0xA2 QUIET 0xA3 PERFORMANCE 0xA4 LOW_POWER 0xA5Thermal Table Basic: QUIET 0x96 BALANCED 0x97 BALANCED_PERFORMANCE 0x98 PERFORMANCE 0x99Devices are known to implement only one of these tables without mixingtheir thermal codes.The fact that the least significant digit of every thermal code isconsecutive of one another is exploited to efficiently match codesthrough arrays.Autodetection of available codes is done through operation LIST_IDS ofmethod THERMAL_INFORMATION. This operation lists fan IDs, CPU sensor ID,GPU sensor ID and available thermal profile codes, *in that order*. Asnumber of fans and thermal codes is very model dependent, almost everyID is scanned and matched based on conditions found onis_wmax_thermal_code(). The known upper bound for the number of IDs is13, corresponding to a device that have 4 fans, 2 sensors and 7 thermalcodes.Additionally G-Series laptops have a key called G-key, which (with AWCCproprietary driver) switches the thermal mode to an special mode namedGMODE with code 0xAB and changes Game Shift Status to 1. Game Shift is amode the manufacturer claims, increases gaming performance.GAME_SHIFT_STATUS method is used to mimic this behavior when selectingPLATFORM_PROFILE_PERFORMANCE option.All of these profiles are known to only change fan speed profiles,although there are untested claims that some of them also change powerprofiles.Activating a thermal mode with method THERMAL_CONTROL may cause shorthangs. This is a known problem present on every platform.Signed-off-by: Kurt Borja Reviewed-by: Ilpo Järvinen Reviewed-by: Armin Wolf Link: https://lore.kernel.org/r/20241030001124.7589-1-kuurtb@gmail.comSigned-off-by: Ilpo Järvinen List of files: /linux-6.15/drivers/platform/x86/dell/Kconfig

ab58016c - platform/x86:dell-laptop: Add knobs to change battery charge settings

Tue, 20 Aug 2024 07:30:05 +0000

platform/x86:dell-laptop: Add knobs to change battery charge settingsThe Dell BIOS allows you to set custom charging modes, which is usefulin particular for extending battery life. This adds support for tweakingthose various settings from Linux via sysfs knobs. One might, forexample, have their laptop plugged into power at their desk the vastmajority of the time and choose fairly aggressive battery-savingsettings (eg, only charging once the battery drops below 50% and onlycharging up to 80%). When leaving for a trip, it would be more usefulto instead switch to a standard charging mode (top off at 100%, chargeany time power is available). Rebooting into the BIOS to change thecharging mode settings is a hassle.For the Custom charging type mode, we reuse the commoncharge_control_{start,end}_threshold sysfs power_supply entries. TheBIOS also has a bunch of other charging modes (with varying levels ofusefulness), so this also adds a 'charge_type' sysfs entry that maps thestandard values to Dell-specific ones.This work is based on a patch by Perry Yuan andLimonciello Mario submitted back in 2020.Hans de Goede:s/charge_type/charge_types/ since charge_types_show() used the newcharge_types power-supply property output format.Signed-off-by: Andres Salomon Reviewed-by: Pali Rohár Link: https://lore.kernel.org/r/20240820033005.09e03af1@5400Reviewed-by: Hans de Goede Signed-off-by: Hans de Goede List of files: /linux-6.15/drivers/platform/x86/dell/Kconfig

platform/x86: Add new Dell UART backlight driverDell All In One (AIO) models released after 2017 use a backlight controllerboard connected to an UART.In DSDT this uart port will be defined as: Name (_HID, "DELL0501") Name (_CID, EisaId ("PNP0501")Instead of having a separate ACPI device with an UartSerialBusV2() resourceto model the backlight-controller, which would be the standard way to dothis.The acpi_quirk_skip_serdev_enumeration() has special handling for thisand it will make the serial port code create a serdev controller devicefor the UART instead of a /dev/ttyS0 char-dev. It will also createa dell-uart-backlight driver platform device for this driver to bind too.This new kernel module contains 2 drivers for this:1. A simple platform driver which creates the actual serdev device (with the serdev controller device as parent)2. A serdev driver for the created serdev device which exports the backlight functionality uses a standard backlight class device.Reported-by: Roman Bogoyev Tested-by: Roman Bogoyev Tested-by: Kai-Heng Feng Co-developed-by: AceLan Kao Signed-off-by: AceLan Kao Signed-off-by: Hans de Goede Link: https://lore.kernel.org/r/20240513144603.93874-2-hdegoede@redhat.com List of files: /linux-6.15/drivers/platform/x86/dell/Kconfig
