What thermal limiting methods are being used? Is idle injection being used? Or CPU frequency limiting or both.
How do I find out?
From the turbostat data you do not appear to be using the TCC offset method. This line:
cpu0: MSR_IA32_TEMPERATURE_TARGET: 0x0f690080 (105 C)
whereas on my test computer, using the TCC offset method, shows:
cpu0: MSR_IA32_TEMPERATURE_TARGET: 0x14641422 (80 C) (100 default - 20 offset)
To check if thermal is being used do:
systemctl status thermal
chromeos doesn't use systemd. A quick ps grep doesn't show any thermal-related processes.
