Hi community,


I have some questions about i.MX6DQ thermal control.

Actually, our partner want to disable the thermal control to prevent lower cpu frequency.

Then, please see our questions as following.



Please see chapter 26 of i.MX6 linux reference manual in L3.10.17_1.0.0-ga (IMX6LXRM Rev L3.10.17_1.0.0-ga).

I understand i.MX6DQ CPU and GPU run at a lower frequency when reaching passive point.

So decreasing of processing capacity of CPU and GPU is not avoidable when cooling is active.

Is this correct?



To disable the thermal control, I think there are two method.

A. Remove thermal driver with bitbake menuconfig.

B. Execute the following command.

   cat disable > /sys/class/thermal/thermal_zone0/mode

Is this correct?
