What is the difference between GPU_POWER_CONTROL_ENABLE and GPU_POWER_CONTROL_DISABLE?
In my knowledge, if GPU_POWER_CONTROL_ENABLE is ON, DVFS of GPU is activated and managed by DVFS Governor. However, I’m curious about why GPU_POWER_CONTROL_DISABLE exists, and why the values of this option is set to ‘auto’ by default.
Hi,
The two definitions are for configuring the GPU. In order to configure:
GPU MIN_FREQ 0
GPU MAX_FREQ 306000000
The node /sys/devices/platform/gpu.0/power/control has to be on first and then back to auto.
Thanks, I understand how it works. You mean that to configure the GPU’s max frequency and min frequency, I have to set power control enable on, and back to auto after setting its frequency.
