Thank you for your response.

I did my development and testing on a Dell Intel system. Specifically the XPS 15 9560 with i7-7700HQ.

I do have thermald running, though I admit I am not really aware of what exactly it does, besides being related to thermals in some way.

I normally set the thermal mode with Dell's smbios-thermal-ctl program. I am not too sure all the values that the bios configures on it's own depending on the provided mode, so I am not sure if thermald conflicts. But my understanding is that would be out of scope of this driver, since we are only telling the bios what we want at a high level.
