"@Colin I am using an ASUS Z170M-Plus MB (https://www.asus.com/sg/Motherboards/Z170M-PLUS/specifications/). It's UEFI is equip to perform active thermal management of the CPU and a few other locations on the MB."
..I could not find the source of information you are referring to about " UEFI is equip to perform active thermal management of the CPU and a few other locations on the MB". Can you point me to that assertion? "Is there a reason why the devices of TRT and ART are not detected? Are these tables required to monitor and control temperatures on my CPU and MB?" _TRT and _ART are ACPI control objects, see sections 11.4.19 _TRT (Thermal Relationship Table) and 11.4.3 _ART (Active Cooling Relationship Table) of the ACPI specification, http://www.uefi.org/sites/default/files/resources/ACPI_6_1.pdf The kernel driver (drivers/thermal/int340x_thermal/acpi_thermal_rel.c) attempts to evaluate these objects and these fail to evaluate (most probably because they don't exist) hence these interfaces are not exposed in a working state to user space programs such as thermald. It is highly probably that the BIOS vendor just didn't implement these ACPI objects. If they did not, well, that's the way it is. Debugging and fixing the firmware is out of scope for this kind of bug report. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1582982 Title: thermald 1.5-2ubuntu1 failures in ubuntu16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thermald/+bug/1582982/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
