Phoronix: More ASUS Motherboard Sensors & Other Hardware Monitoring Improvements For Linux 5.20

Ahead of the Linux 5.19 stable kernel being launched later today, a few pull requests have already begun queuing for the Linux 5.20 merge window. Among those early pulls are the hardware monitoring "HWMON" subsystem updates...

I've always bought ASUS motherboards, but this time I went with MSI... Their use of strange variants of NCT Super I/O chips is complicated, thus proper HWMON support is complicated and needs an outside community module (https://github.com/Fred78290/nct6687d). Next time I'm going to stick with ASUS again.

I also need this for my Zenith II extreme Mobo.
I wonder if it's still required with 5.20.

the new asus sensor stuff sure is nice, being able to see various temps and sensors I don't have xD

i use a msi b550 tomahawk. never knew about this. i figured what lmsensors was showing me was good enough. ill give this module a try.

Here I am with my ASUS PRIME B450-PLUS with no support Well, I guess I could check if there's support for it (BIOS has updated several times along the years...)

With all the hacking Gunter is doing to the LM90 driver to support so many things...perhaps we'll hear in future releases that it also works as a:

• can opener
• knife sharpener
• pitchfork
• TESLA car charger

On the other hand, I guess when the only tool that you have is a hammer, then every problem looks like a nail.

Hi,
have you tried that driver and does it work? It doesn't look like the correct chip to me.

On my ASUS Zenith II Extreme (non Alpha, but I think they are the same), the chip identifies as a nct6798D. I think it's the nct6775 kernel driver that manages this.

This kernel shows me this in sensors:

The new code in 5.20 extends the asusec driver, and adds this block to the sensors output:

asusec-isa-0000

Water_Flow:         0 RPM
Chipset:          +74.0°C
CPU:              +53.0°C
Motherboard:      +47.0°C
T_Sensor:         -40.0°C
VRM:              +52.0°C
Water_In:         -40.0°C
Water_Out:        -40.0°C
Water_Block_In:   -40.0°C
Water_Block_Out:  -40.0°C
T_sensor_2:       +39.0°C
Extra_1:          -40.0°C
Extra_2:          -40.0°C
Extra_3:          -40.0°C
CPU:              11.00 A

What's displayed depends on what you have connected on your motherboard (-40.0°C is the value displayed when nothing is connected to a sensor).

It looks like there are not a lot of Zenith II Extreme Linux hackers around, haven't seen a lot of work happen to support them.
