Comment 32 for bug 1873083

Hi!

I have C940-14IIL, running under Fedora 32 and I am very pleased by this laptop. Everything is OK, except shutdown/reboot (workaround i915.enable_psr=0 kernel option), fingerprint reader (do not care) and overheating shutdown.

I have resolved my overheating problem by installing the last version 2.2 of thermald from Github and automatically creating config bydptfxtract (https://github.com/intel/dptfxtract).
The bydptfxtract create 10 different thermal-conf.xml. I have tested all of them and I am attaching the most successful of them.

I did a stress test with full load for 10 minutes. Following is the uptime output:
14:47:46 up 18:57, 1 user, load average: 8.49, 9.10, 7.25

During the test temperature vary around 75-80 degree - something that I could not imagine before installing the thermald. One virtual machine and a minute of compilation or R calculations would certainly cause overheating shutdown.

Actually, as far as can explain the results, the thermald do a CPU scaling of the CPU speed in range 2.5-2.8 GHz - about 1 GHz below the maximum speed - something that I definitely agree. Scaling is done after the rise of the temperature and I do not experience any inconvenience, troubles or interruptions with the lower speed.
