Did you figure out how to make custom gt_min_freq_mhz setting permanent?

Edit: Nevermind, adding it to autostart.sh actually works. It always stays at max frequency when playing video (I use 750 Mhz) and switch to 100 Mhz when Kodi does nothing.    

Can you post the actual content of your autostart.sh? Would like to check it against mine. Also the what device are you running on?     

Code:

echo 750 > /sys/devices/pci0000:00/0000:00:02.0/drm/card0/gt_min_freq_mhz

Running on Asrock J4105B-ITX board. 

Thanks!
