## NCT6687D Kernel module
|
|
|
|
This kernel module permit to recognize the chipset Nuvoton NCT6687-R in lm-sensors package.
|
|
This sensor is present on some B550 motherboard such as MSI or ASUS.
|
|
|
|
The implementation is minimalist and was done by reverse coding of Windows 10 source code from [LibreHardwareMonitor](https://github.com/LibreHardwareMonitor/LibreHardwareMonitor)
|
|
|
|
## Installation
|
|
|
|
To install this module, you need a buid environment. Exemple for Ubuntu
|
|
|
|
```shell
|
|
apt-get install build-essential linux-headers-`uname -r`
|
|
```
|
|
|
|
Clone this repository and go to source directory, just run make install. During install, you could be asked for your password because some commands are sudoed.
|
|
|
|
```shell
|
|
make install
|
|
```
|

## Tested
|
|
|
|
This module was tested on Ubuntu 20.04 with [Linux Kernel 5.8.18-050818-generic](https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8.18/) on motherboard [MAG-B550-TOMAHAWK](https://www.msi.com//Motherboard/MAG-B550-TOMAHAWK) running an [AMD 3900X](https://www.amd.com/en/products/cpu/amd-ryzen-9-3900x)

## TODO
|
|
|
|
**1. Fan speed control**
|
|
|
|
- Changing fan speed and restore to default value not tested.
|
|
- Becareful probably fan speed could down to 0 RPM
