Those were removed from mainline kernels by Chromebook devs,
wanting to protect their broken babies at all cost.
This patch was dully tested here :
https://forum.armbian.com/topic/13515-panfrost-on-rk3288-and-gpu-on-600mhz-problems/
But you're welcome to test it again !
I did it, with a whole glmark2 round and it worked flawlessly.
To test the GPU at that frequency, locate the **devfreq** folder of your GPU unit on your system (For tinkerboards, it's in **/sys/devices/platform/ffa30000.gpu/devfreq/ffa30000.gpu**) and then :
* Check the available frequencies by doing `sudo cat available_frequencies` .
That should output something like this : `100000000 200000000 300000000 400000000 500000000 600000000`
Be sure that `500000000` is in the list.
* Setup the minimum GPU frequency to 500Mhz like this : `sudo echo 500000000 > min_freq`
You can also set up the GPU to not go over 500Mhz like this : `sudo echo 500000000 > max_freq`

armbian-firstrun: exclude helios64 from generating fixed_mac
Each network interface on Helios64 already assigned to unique MAC
address in factory. Assigning Network Manager with cloned MAC is not
needed.
