2024-01-02hwmon: Add driver for Gigabyte AORUS Waterforce AIO coolersAleksa Savic
This driver exposes hardware sensors of the Gigabyte AORUS Waterforce all-in-one CPU liquid coolers, which communicate through a proprietary USB HID protocol. Report offsets were initially discovered in [1] and confirmed by me on a Waterforce X240 by observing the sent reports from the official software. Available sensors are pump and fan speed in RPM, as well as coolant temperature. Also available through debugfs is the firmware version. Attaching a fan is optional and allows it to be controlled from the device. If it's not connected, the fan-related sensors will report zeroes. The addressable RGB LEDs and LCD screen are not supported in this driver and should be controlled through userspace tools.

2023-10-29hwmon: Add driver for ltc2991Antoniu Miclaus
Add support for LTC2991 Octal I2C Voltage, Current, and Temperature Monitor. The LTC2991 is used to monitor system temperatures, voltages and currents. Through the I2C serial interface, the eight monitors can individually measure supply voltages and can be paired for differential measurements of current sense resistors or temperature sensing transistors. Additional measurements include internal temperature and internal VCC.

SMM665 and related chips are power controller/sequencer chips from Summit Microelectronics. The company was acquired by Qualcomm in 2012, and support for the chip series stopped. The chips are long since gone from active use, making the driver unsupportable and just consuming space and compile time. Remove it. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2023-06-08hwmon: add HP WMI Sensors driverJames Seo
Hewlett-Packard (and some HP Compaq) business-class computers report hardware monitoring information via WMI. This driver exposes that information to hwmon. Initial support is provided for temperature, fan speed, and intrusion sensor types. Provisional support is provided for voltage and current sensor types. HP's WMI implementation permits many other types of numeric sensors. Therefore, a debugfs interface is also provided to enumerate and inspect all numeric sensors visible on the WMI side. This should facilitate adding support for other sensor types in the future. Tested on a HP Z420, a HP EliteOne 800 G1, and a HP Compaq Elite 8300 SFF. Note that provisionally supported sensor types are untested and seem to be rare-to-nonexistent in the wild, having been encountered neither on test systems nor in ACPI dumps from the Linux Hardware Database. They are included because their popularity in general makes their presence on past or future HP systems plausible and because no doubt exists as to how the sensors themselves would be represented in WMI (alarm attributes will need to wait for hardware to be located). A 2005 HP whitepaper gives the relevant sensor object MOF definition and sensor value scaling calculation, and both this driver and the official HP Performance Advisor utility comply with them (confirmed in the latter case by reverse engineering).

2022-12-04hwmon: add OneXPlayer mini AMD sensors driverJoaquín Ignacio Aramendía
Sensors driver for OXP Handhelds from One-Netbook that expose fan reading and control via hwmon sysfs. As far as I could gather all OXP boards have the same DMI strings and they can be told appart only by the boot cpu vendor (Intel/AMD). Currently only AMD boards are supported since Intel have different EC registers and values to read/write. Fan control is provided via pwm interface in the range [0-255]. AMD boards have [0-100] as range in the EC, the written value is scaled to accommodate for that.

2021-12-26hwmon: add driver for NZXT RGB&Fan Controller/Smart Device v2.Aleksandr Mezin
This driver implements monitoring and control of fans plugged into the device. Besides typical speed monitoring and PWM duty cycle control, voltage and current are reported for every fan. The device also has 2 connectors for RGB LEDs, support for them isn't implemented (mainly because there is no standardized sysfs interface). Also, the device has a noise sensor, but the sensor seems to be completely useless (and very imprecise), so support for it isn't implemented too. The driver coexists with userspace tools that access the device through hidraw interface with no known issues. The driver has been tested on x86_64, built in and as a module. Some changes/improvements were suggested by Jonas Malaco.

Many ASUS motherboards do not publish all the available sensors via the Super I/O chip but the missing ones are available through the embedded controller (EC) registers. This driver implements reading those sensor data via the WMI method BREC, which is known to be present in all ASUS motherboards based on the AMD 500 series chipsets (and probably is available in other models too). The driver needs to know exact register addresses for the sensors and thus support for each motherboard has to be added explicitly. The EC registers do not provide critical values for the sensors and as such they are not published to the HWMON. Supported motherboards: * PRIME X570-PRO * Pro WS X570-ACE * ROG CROSSHAIR VIII HERO * ROG CROSSHAIR VIII DARK HERO * ROG CROSSHAIR VIII FORMULA * ROG STRIX X570-E GAMING * ROG STRIX B550-I GAMING * ROG STRIX B550-E GAMING Co-developed-by: Eugene Shalygin <eugene.shalygin@gmail.com> Signed-off-by: Eugene Shalygin <eugene.shalygin@gmail.com> Co-developed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Denis Pauk <pauk.denis@gmail.com> Tested-by: Tor Vic <torvic9@mailbox.org> Tested-by: Oleksandr Natalenko <oleksandr@natalenko.name> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2021-08-28hwmon: add driver for Aquacomputer D5 NextAleksa Savic
This driver exposes hardware sensors of the Aquacomputer D5 Next watercooling pump, which communicates through a proprietary USB HID protocol. Available sensors are pump and fan speed, power, voltage and current, as well as coolant temperature. Also available through debugfs are the serial number, firmware version and power-on count. Attaching a fan is optional and allows it to be controlled using temperature curves directly from the pump. If it's not connected, the fan-related sensors will report zeroes. The pump can be configured either through software or via its physical interface. Configuring the pump through this driver is not implemented, as it seems to require sending it a complete configuration. That includes addressable RGB LEDs, for which there is no standard sysfs interface. Thus, that task is better suited for userspace tools. This driver has been tested on x86_64, both in-kernel and as a module. Signed-off-by: Aleksa Savic <savicaleksa83@gmail.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

On AMD platforms the Out-of-band access is provided by Advanced Platform Management Link (APML), APML is a SMBus v2.0 compatible 2-wire processor client interface. APML is also referred as the sideband interface (SBI). APML is used to communicate with the Side-Band Remote Management Interface (SB-RMI) which provides Soft Mailbox messages to manage power consumption and power limits of the CPU socket. - This module add support to read power consumption, power limit & max power limit and write power limit. - To instantiate this driver on a Board Management Controller (BMC) connected to an AMD CPU with SB-RMI support, the i2c bus number would be the bus connected from the BMC to the CPU.

2021-04-20hwmon: add driver for NZXT Kraken X42/X52/X62/X72Jonas Malaco
These are "all-in-one" CPU liquid coolers that can be monitored and controlled through a proprietary USB HID protocol. While the models have differently sized radiators and come with varying numbers of fans, they are all indistinguishable at the software level. The driver exposes fan/pump speeds and coolant temperature through the standard hwmon sysfs interface. Fan and pump control, while supported by the devices, are not currently exposed. The firmware accepts up to 61 trip points per channel (fan/pump), but the same set of trip temperatures has to be maintained for both; with pwmX_auto_point_Y_temp attributes, users would need to maintain this invariant themselves. Instead, fan and pump control, as well as LED control (which the device also supports for 9 addressable RGB LEDs on the CPU water block) are left for existing and already mature user-space tools, which can still be used alongside the driver, thanks to hidraw. A link to one, which I also maintain, is provided in the documentation. The implementation is based on USB traffic analysis. It has been runtime tested on x86_64, both as a built-in driver and as a module.

2021-01-27hwmon: (abx500) Decomission abx500 driverGuenter Roeck
This deletes the ABx500 hwmon driver, the only supported variant being the AB8500. This driver has been replaced by generic frameworks. By inspecting the abx500 sysfs files we see that it contains things such as temp1_max, temp1_max_alarm, temp1_max_hyst, temp1_max_hyst_alarm, temp1_min, temp1_min_alarm. It becomes obvious that the abx500.c is a reimplementation of thermal zones. This is not very strange as the generic thermal zones were not invented when this driver was merged so people were rolling their own. The ab8500.c driver contains conversion tables for handling a thermistor on ADC channels AUX1 and AUX2. I managed to replace the functionality of the driver with: - Activation of the ntc_thermistor.c driver, CONFIG_SENSORS_NTC_THERMISTOR - Activation of thermal zones, CONFIG_THERMAL - In the device tree, connecting the NTC driver to the processed IIO channels from the AB8500 GPADC ADC forming two instances of NTC sensors. - Connecting the two NTC sensors to a "chassis" thermal zone in the device tree and setting that to hit the CPU frequency at 50 degrees celsius and do a critical shutdown at 70 degrees celsius, deploying a policy using the sensors. After talking to the original authors we concluded that the driver was never properly parameterized in production so what we now have in the device tree is already puts the thermistors to better use than what the hwmon driver did. The two remaining channels for two battery temperatures is already handled in the charging algorithms but can be optionally extended to thermal zones as well if we want these to trigger critical shutdown for the platform.

2020-12-12hwmon: (sbtsi) Add basic support for SB-TSI sensorsKun Yi
SB Temperature Sensor Interface (SB-TSI) is an SMBus compatible interface that reports AMD SoC's Ttcl (normalized temperature), and resembles a typical 8-pin remote temperature sensor's I2C interface to BMC. This commit adds basic support using this interface to read CPU temperature, and read/write high/low CPU temp thresholds. To instantiate this driver on an AMD CPU with SB-TSI support, the i2c bus number would be the bus connected from the board management controller (BMC) to the CPU. The i2c address is specified in Section 6.3.1 of the spec [1]: The SB-TSI address is normally 98h for socket 0 and 90h for socket 1, but it could vary based on hardware address select pins.

The Corsair digital power supplies of the series RMi, HXi and AXi include a small micro-controller with a lot of sensors attached. The sensors can be accessed by an USB connector from the outside. This micro-controller provides the data by a simple proprietary USB HID protocol. The data consist of temperatures, current and voltage levels, power usage, uptimes, fan speed and some more. It is also possible to configure the PSU (fan mode, mono/multi-rail, over current protection). This driver provides access to the sensors/statistics of the RMi and HXi series power supplies. It does not support configuring these devices, because there would be many ways to misconfigure or even damage the PSU.

2020-07-24hwmon: add Corsair Commander Pro driverMarius Zachmann
This is v7 of a driver for the Corsair Commander Pro. It provides sysfs attributes for: - Reading fan speed - Reading temp sensors - Reading voltage values - Writing pwm and reading last written pwm - Reading fan and temp connection status It is an usb driver, so it needs to be ignored by usbhid. The Corsair Commander Pro is a fan controller and provides no means for user interaction. The two device numbers are there, because there is a slightly different version of the same device. (Only difference seem to be in some presets.) Squashed: hwmon: (corsair-cpro) add fan_target This adds fan_target entries to the corsair-cpro driver. Reading the attribute from the device does not seem possible, so it returns the last set value (same as pwm). send_usb_cmd now has one more argument, which is needed for the fan_target command. hwmon: corsair-cpro: Change to HID driver This changes corsair-cpro to a hid driver using hid reports.
