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.

 

[Q1]

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?

 

[Q2]

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?

 

 

Best Regards,
