_Hwmon Linux kernel driver for monitoring Asus ROG Ryujin AIO coolers_

## Overview

The following device(s) are supported by this driver:

* ASUS ROG RYUJIN II 360, since kernel v6.9

It's very likely that 240 is supported as well, but no one has tested that yet.

Being a standard `hwmon` driver, it provides readings via `sysfs`, which are easily accessible through `lm-sensors` as usual.

Report offsets were initially taken from [here](https://github.com/liquidctl/liquidctl/pull/653).

## Installation and usage

First, clone the repository by running:

```commandline

git clone https://github.com/aleksamagicka/asus_rog_ryujin-hwmon.git

```

Then, compile it and insert it into the running kernel, replacing the existing instance (if needed):

```commandline

make dev

```

You can then try running `sensors` and your device(s) should be listed there.

### Setting fan speeds

Pump, embedded/internal fan and fans connected to the controller can be controlled. Find the appropriate entry under

`/sys/class/hwmon` (you'll need root) and echo 0-255 values to pwm1, pwm2 or pwm3, respectively. For example:

```commandline

echo 200 > /sys/class/hwmon/hwmonX/pwm1

```

where `hwmonX` will be the entry for your AIO. You can check that it's the one by looking up it's name:

```commandline

cat /sys/class/hwmon/hwmonX/name

```

which should be `rog_ryujin`.
