# metaboxfan - Metabox Fan control module

Kernel module that provides fan control for various Metabox mainboards via standard hwmon interfaces (to use with generic fan control softwares like lm-sensors, pwmconfig, fancontrol, ...).

## Forked Project

This project has been forked from https://github.com/simopil/clevofan as changes were required for board and vendor names in order to get working.

Name changed to prevent conflicts.

## Supported models

```bash

L14xMU: supported and completely tested

```

* Theoretically supports all Metabox laptops but I have to add correct DMI_BOARD_NAME string and fan number to make module load without force_match parameter. Please open an issue "Add support for *model*" and attach the output file of *dmi_info_dump* script, then I'll add support (look "parameters" section for tests).

## Features

* Up to 3 fans supported

* FAN Speed Reading

  - Exposed hwmon device for reading fan speed provided by EC

* Fan Speed Control

  - Exposed hwmon PWM interface to make every fan control software capable of controlling the fan speed

  - pwmX-enable possible values are 


  1 -> manual speed 


  2 -> default EC automatic speed

## Parameters

* force_match [default:0] force driver to match with non-compatible mainboard, set number of fans to enable

  

## Please read CAREFULLY

This module executes write operations on the mainboard's Embedded Controller (EC). Thus reading is totally secure, issuing fan speed commands can teoretically put EC in a bad state until system is rebooted. This is caused by the nature of fan speed command, because is splitted in two different calls to EC: first one specifies the fan, second one the speed. If another module/acpi stuffs issues a command between those two calls, EC response/action is unpredictable.

## Install

```bash

make

make install

```

## Load

```bash

modprobe metaboxfan

```
