mbpfan does not detect the applesmc plugin

[Dizspy]

I have Mac mini 2018 (Macmini8,1)

I've installed proxmox with custom linux kernel v5.19.17-1 for T2 support
https://github.com/AdityaGarg8/pve-edge-kernel-t2

applesmc plugin successfully loaded
root@proxmox:/# lsmod |grep smc
applesmc 32768 0

sensors are successfully detecting all the values:

Anyway, mbpfan does not detect the applesmc plugin
root@proxmox:/# mbpfan
mbpfan needs applesmc support. Please either load it or build it into the kernel. Exiting.

How can I manually point mbpfan to detect the applesmc correctly to make it work?

[Redecorating]

Upstream mbpfan doesn't yet have the right folder path to work with the patched T2 kernels (#236 ), please have a look at this https://wiki.t2linux.org/guides/fan/ for now.

[Dizspy]

Thanks. I've managed to patch and make mbpfan for the right folder.

But now there is another issue:

root@proxmox:~# mbpfan -f

mbpfan could not detect any fan. Please contact the developer.

mbpfan could not detect the fan. Despite the fact that 'sensors' detected fan1 successfully.

Hi, @Dizspy some time ago I checked this issue and I had the same problem, it seems that mbpfan could not read the applesmc and only took the coretemp temperature, which was lower than what my applesmc was reading.

I have developed a script that may solve your problem, as it also solved mine https://github.com/zft9xgy/mac-temp2fan-controler the code is still in its first version so it is possible to find some bugs.

This works, thank!

I'm happy to merge PRs to improve fan or sensor support -- please test and submit them since I lack hardware for these.

[zft9xgy]

Yes, that is probably the best idea at that time but I don't got enough skill on dev and got at that time so I choose to build my own...

And right now I don't got the hardware available, maybe in the future I will got it again and I will do the fork+pr.

Thanks !!
