I have MSI MAG Z690 Tomahawk motherboard and Intel i9-12900k.
I’ve run sensors-detect again and this time I’ve noticed that I do have some unknown sensors in the output.
Found unknown chip with ID 0xd592
So after searching a bit I found out that there is a NCT6686D hardware monitoring IC on the motherboard and it’s missing driver.
I’ve found the driver:
And tried to install it:
sudo qubes-dom0-update make automake gcc gcc-c++ kernel-latest-devel dkms
make dkms/install
But got this error because of some extra quotes:
make -C /lib/modules/5.17.5-1.fc32.qubes.x86_64/build M=/home/user/Downloads/nct6687d-main2/5.17.5-1.fc32.qubes.x86_64 modules
make[1]: Entering directory '/usr/src/kernels/5.17.5-1.fc32.qubes.x86_64'
/bin/sh: -c: line 0: syntax error near unexpected token `('
/bin/sh: -c: line 0: `if [ "gcc (GCC) 10.3.1 20210422 (Red Hat 10.3.1-1)" != ""gcc (GCC) 10.3.1 20210422 (Red Hat 10.3.1-1)"" ]; then \'
make[1]: *** [Makefile:1717: prepare] Error 1
make[1]: Leaving directory '/usr/src/kernels/5.17.5-1.fc32.qubes.x86_64'
make: *** [Makefile:11: build] Error 2
And fixed it for now with patching kernel headers:
sudo sed -i "s/CONFIG_CC_VERSION_TEXT=\"gcc (GCC) 10.3.1 20210422 (Red Hat 10.3.1-1)\"/CONFIG_CC_VERSION_TEXT='gcc (GCC) 10.3.1 20210422 (Red Hat 10.3.1-1)'/g" /usr/src/kernels/5.17.5-1.fc32.qubes.x86_64/include/config/auto.conf
Then kernel module installed successfully.
Now I can see some hardware monitoring info from motherboard:

I guess CPU temperature is CPU package temperature here.
I also have some unknown SMBus device in sensors-detect
Found unknown SMBus adapter 8086:7aa3 at 0000:00:1f.4.
It seems to be Alder Lake-S PCH SMBus Controller and I can see that it’s driver is loaded:
[user@dom0 ~]$ lsmod | grep i2c_i801
i2c_i801 36864 0
i2c_smbus 20480 1 i2c_i801
But the coretemp driver can’t be loaded as it can’t find the device:
[user@dom0 ~]$ lsmod | grep coretemp
[user@dom0 ~]$ sudo modprobe coretemp
modprobe: ERROR: could not insert 'coretemp': No such device
I’ve found this page where it says:
For my system coretemp and i2c-i801 driver need to loaded in order to see sensors data.
https://www.cyberciti.biz/faq/howto-linux-get-sensors-information/
So it seems to me that coretemp can’t find the device because Xen hid it.
Also acpitz sensor seems to be a dummy one as its temperature is not changing.
