I have bought a fanless PC, and it is really important for me to have some form of power management for this PC, because currently I don't under Qubes, and the result is that if I do something that puts a lot of load on the CPU like playing a full-screen video in Firefox, the CPU overheats and the system (firmware?) automatically goes into emergency power-saving mode, which involves making the CPU go really slow.

I have transferred responsibility to the Linux kernel for power management by adding cpufreq=dom0-kernel to the Xen command line. This doesn't help.

I have then tried to switch from the intel pstate driver (which doesn't work with my Rocket Lake CPU, an Intel® Core™ i7-11700) to the acpi-cpufreq driver by adding intel_pstate=disable. This also doesn't help - sudo cpupower frequency-info shows "no or unknown cpufreq driver is active on this CPU".

I then installed the latest version of thermald on my dom0 domain, but thermald is not able to find any temperature sensors:

[WARN]Thermal DTS: No coretemp sysfs found

I have ran sudo sensors-detect, but that didn't help.

I have then ran modprobe processor_thermal_rapl and modprobe processor_thermal_device and restarted thermald, but it still showed the same errors.

My motherboard is an Asus TUF GAMING B560M-PLUS WIFI.

Please help me to enable some form of thermal throttling / frequency governor on this PC, other than the firmware's emergency thermal throttling.

  • Also tried acpi=force and blacklisting xen_acpi_processor, but those didn't help either. Commented May 1, 2022 at 13:15
  • Are any of the required kernel modules loaded, such as coretemp? Commented May 1, 2022 at 14:01
  • @Bib When I tried sudo modprobe coretemp, I got modprobe: ERROR: could not insert 'coretemp': No such device. Commented May 9, 2022 at 6:54

Maybe it's my imagination, but it seems like adding intel_pstate=disable rdblacklist=xen_acpi_processor to the kernel command line has solved the original problem, so that I don't need thermald after all.

I'm not sure how that can be the case though, since no driver or process is now controlling the CPU frequency...

EDIT: Just to confirm, over a year later, I have had zero overheating events - except one incident where the PC shut down for unknown reasons, which I guess could have been an overheating event. That said, I mostly use this PC for web browsing, so it's not usually very overtaxed.
