Add a new driver for Uniwill laptops. The driver uses a ACPI interface to talk with the embedded controller, but relies on a ACPI WMI interface for receiving event notifications. The driver is reverse-engineered based on the following information: - OEM software from intel - https://github.com/pobrn/qc71_laptop - https://gitlab.com/tuxedocomputers/development/packages/tuxedo-drivers - https://github.com/tuxedocomputers/tuxedo-control-center The underlying EC supports various features, including hwmon sensors, battery charge limiting, a RGB lightbar and keyboard-related controls.

SPDX-License-Identifier: GPL-2.0-or-later + +======================================== +Uniwill Notebook driver (uniwill-laptop) +======================================== + +Introduction +============ + +Many notebooks manufactured by Uniwill (either directly or as ODM) provide a EC interface +for controlling various platform settings like sensors and fan control.

This makes the WMI-GUID unusable for autoloading. + +WMI method GetULong() +--------------------- + +This WMI method was copied from the Windows driver samples and has no function. + +WMI method SetULong() +--------------------- + +This WMI method was copied from the Windows driver samples and has no function. + +WMI method FireULong() +---------------------- + +This WMI method allows to inject a WMI event with a 32-bit payload. Its primary purpose seems +to be debugging. + +WMI method GetSetULong() +------------------------ + +This WMI method is used to communicate with the EC. The ``Data`` argument holds the following +information (starting with the least significant byte): + +1. 16-bit address +2. 16-bit data (set to ``0x0000`` when reading) +3. 16-bit operation (``0x0100`` for reading and ``0x0000`` for writing) +4. 16-bit reserved (set to ``0x0000``) + +The first 8 bits of the ``Return`` value contain the data returned by the EC when reading. +The special value ``0xFEFEFEFE`` is used to indicate a communication failure with the EC. + +WMI method GetButton() +---------------------- + +This WMI method is not implemented on all machines and has an unknown purpose. + +Reverse-Engineering the EC WMI interface +======================================== + +.. warning:: Randomly poking the EC can potentially cause damage to the machine and other unwanted + side effects, please be careful. + +The EC behind the ``GetSetULong`` method is used by the OEM software supplied by the manufacturer. +Reverse-engineering of this software is difficult since it uses an obfuscator, however some parts +are not obfuscated. In this case `dnSpy <https://github.com/dnSpy/dnSpy>`_ could also be helpful. + +The EC can be accessed under Windows using powershell (requires admin privileges): + +:: + + > $obj = Get-CimInstance -Namespace root/wmi -ClassName AcpiTest_MULong | Select-Object -First 1 + > Invoke-CimMethod -InputObject $obj -MethodName GetSetULong -Arguments @{Data = <input>} + +WMI event interface description +=============================== + +The WMI interface description can also be decoded from the embedded binary MOF (bmof) +data: + +:: + + [WMI, Dynamic, Provider("WmiProv"), Locale("MS\\0x409"), + Description("Class containing event generated ULong data"), + guid("{ABBC0F72-8EA1-11d1-00A0-C90629100000}")] + class AcpiTest_EventULong : WmiEvent { + [key, read] string InstanceName; + [read] boolean Active; + + [WmiDataId(1), read, write, Description("ULong Data")] uint32 ULong; + }; + +Most of the WMI-related code was again copied from the Windows driver samples, causing this WMI +interface to suffer from the same restrictions as the EC WMI interface described above. + +WMI event data +-------------- + +The WMI event data contains a single 32-bit value which is used to indicate various platform events. + +Reverse-Engineering the Uniwill WMI event interface +=================================================== + +The driver logs debug messages when receiving a WMI event. Thus enabling debug messages will be +useful for finding unknown event codes. + +EC ACPI interface description +============================= + +The ``INOU0000`` ACPI device is a virtual device used to access various hardware registers +available on notebooks manufactured by Uniwill. Reading and writing those registers happens +by calling ACPI control methods. The ``uniwill-laptop`` driver uses this device to communicate +with the EC because the ACPI control methods are faster than the WMI methods described above. + +ACPI control methods used for reading registers take a single ACPI integer containing the address +of the register to read and return a ACPI integer containing the data inside said register. ACPI +control methods used for writing registers however take two ACPI integers, with the additional +ACPI integer containing the data to be written into the register. Such ACPI control methods return +nothing. + +System memory +------------- + +System memory can be accessed with a granularity of either a single byte (``MMRB`` for reading and +``MMWB`` for writing) or four bytes (``MMRD`` for reading and ``MMWD`` for writing). Those ACPI +control methods are unused because they provide no benefit when compared to the native memory +access functions provided by the kernel. + +EC RAM +------ + +The internal RAM of the EC can be accessed with a granularity of a single byte using the ``ECRR`` +(read) and ``ECRW`` (write) ACPI control methods, with the maximum register address being ``0xFFF``. +The OEM software waits 6 ms after calling one of those ACPI control methods, likely to avoid +overwhelming the EC when being connected over LPC. + +PCI config space +---------------- + +The PCI config space can be accessed with a granularity of four bytes using the ``PCRD`` (read) and +``PCWD`` (write) ACPI control methods. The exact address format is unknown, and poking random PCI +devices might confuse the PCI subsystem. Because of this those ACPI control methods are not used. + +IO ports +-------- + +IO ports can be accessed with a granularity of four bytes using the ``IORD`` (read) and ``IOWD`` +(write) ACPI control methods. Those ACPI control methods are unused because they provide no benefit +when compared to the native IO port access functions provided by the kernel. + +CMOS RAM +-------- + +The CMOS RAM can be accessed with a granularity of a single byte using the ``RCMS`` (read) and +``WCMS`` ACPI control methods. Using those ACPI methods might interfere with the native CMOS RAM +access functions provided by the kernel due to the usage of indexed IO, so they are unused. + +Indexed IO +---------- + +Indexed IO with IO ports with a granularity of a single byte can be performed using the ``RIOP`` +(read) and ``WIOP`` (write) ACPI control methods. Those ACPI methods are unused because they +provide no benifit when compared to the native IO port access functions provided by the kernel. + +Special thanks go to github user `pobrn` which developed the +`qc71_laptop <https://github.com/pobrn/qc71_laptop>`_ driver on which this driver is partly based. +The same is true for Tuxedo Computers, which developed the +`tuxedo-drivers <https://gitlab.com/tuxedocomputers/development/packages/tuxedo-drivers>`_ package +which also served as a foundation for this driver. diff --git a/MAINTAINERS b/MAINTAINERS index fe168477caa4..99624393f271 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -25903,6 +25903,16 @@ L: linux-scsi@xxxxxxxxxxxxxxx S: Maintained F: drivers/ufs/host/ufs-renesas.c +UNIWILL LAPTOP DRIVER +M: Armin Wolf <W_Armin@xxxxxx> +L: platform-driver-x86@xxxxxxxxxxxxxxx +S: Maintained +F: Documentation/ABI/testing/sysfs-driver-uniwill-laptop +F: Documentation/wmi/devices/uniwill-laptop.rst +F: drivers/platform/x86/uniwill/uniwill-acpi.c +F: drivers/platform/x86/uniwill/uniwill-wmi.c +F: drivers/platform/x86/uniwill/uniwill-wmi.h + UNSORTED BLOCK IMAGES (UBI) M: Richard Weinberger <richard@xxxxxx> R: Zhihao Cheng <chengzhihao1@xxxxxxxxxx> diff --git a/drivers/platform/x86/Kconfig b/drivers/platform/x86/Kconfig index 6d238e120dce..a4c2ea69970d 100644 --- a/drivers/platform/x86/Kconfig +++ b/drivers/platform/x86/Kconfig @@ -74,6 +74,8 @@ config HUAWEI_WMI To compile this driver as a module, choose M here: the module will be called huawei-wmi. +source "drivers/platform/x86/uniwill/Kconfig" + config UV_SYSFS tristate "Sysfs structure for UV systems" depends on X86_UV diff --git a/drivers/platform/x86/Makefile b/drivers/platform/x86/Makefile index a0c5848513e3..a6271588e05a 100644 --- a/drivers/platform/x86/Makefile +++ b/drivers/platform/x86/Makefile @@ -109,6 +109,9 @@ obj-$(CONFIG_TOSHIBA_WMI) += toshiba-wmi.o # before toshiba_acpi initializes obj-$(CONFIG_ACPI_TOSHIBA) += toshiba_acpi.o +# Uniwill +obj-y += uniwill/ + # Inspur obj-$(CONFIG_INSPUR_PLATFORM_PROFILE) += inspur_platform_profile.o diff --git a/drivers/platform/x86/uniwill/Kconfig b/drivers/platform/x86/uniwill/Kconfig new file mode 100644 index 000000000000..d07cc8440188 --- /dev/null +++ b/drivers/platform/x86/uniwill/Kconfig @@ -0,0 +1,38 @@ +# SPDX-License-Identifier: GPL-2.0-or-later +# +# Uniwill X86 Platform Specific Drivers +# + +menuconfig X86_PLATFORM_DRIVERS_UNIWILL + bool "Uniwill X86 Platform Specific Device Drivers" + depends on X86_PLATFORM_DEVICES + help + Say Y here to see options for device drivers for various + Uniwill x86 platforms, including many OEM laptops originally + manufactured by Uniwill. + This option alone does not add any kernel code. + + If you say N, all options in this submenu will be skipped and disabled. + +if X86_PLATFORM_DRIVERS_UNIWILL + +config UNIWILL_LAPTOP + tristate "Uniwill Laptop Extras" + default m + depends on ACPI + depends on ACPI_WMI + depends on ACPI_BATTERY + depends on HWMON + depends on INPUT + depends on LEDS_CLASS_MULTICOLOR + depends on DMI + select REGMAP + select INPUT_SPARSEKMAP + help + This driver adds support for various extra features found on Uniwill laptops, + like the lightbar, hwmon sensors and hotkeys.
