i.MX6 CPU and GPU frequency when cooling by thermal driver.

[satoshishimoda]

Hi community,

Our partner have a question about i.MX6 Linux BSP thermal driver.

Please see chapter 26.1 in i.MX 6 Linux Reference Manual (IMX6LXRM Rev L3.10.17-1.0.0-ga) in Yocto BSP.

It says " When reaching passive point, cooling device will lower CPU frequency and notify GPU to run at a lower frequency."

Then, could you let me know the concrete frequency when the cooling?

(e.g. CPU = xxx MHz, GPU = yyy MHz)

Best Regards,

Satoshi Shimoda

Hi Satoshi

these frequencies are described in

"Software Thermal Driver" AN4579

i.MX 6 Series Thermal Management Guidelines

L3.10.17-1.0.0 setings basically the same and one can verify them

checking sources, mentioned in IMX6LXRM Rev L3.10.17-1.0.0-ga sect.26.3.1 Source Code Structure

Best regards

igor
