I need changing the frequency of the GPU for Khadas vim3 running Android.
There are no mail governors in devfreq to set governor or change the frequency of the GPU with the command line.
I also try to enable mali devfreq in the kernel but this option is not available in the kernel which is used in Khadas AOSP. I am wondering why “arm” directory is missing in drivers/gpu of Khadas AOSP. In Andriod AOSP of this board, there is this option however Android AOSP does not support NPU.
I really appreciate it if you let me know how could I enable GPU DVFS? Why Khadas team do not complete drivers/gpu/ or are they supposed to complete it?
PS: We are designing an embedded lab systems course at university for 20 students, and need GPU DVFS working on this board.
