0.7.9 Linux release from ayufan

[dukla2000]

With this change the cores stay nicely at 1.8 Ghz for me. Just to be clear: This is all with the mainline kernel. I assume it works fine with the 4.4 rockchip kernel.

Yup, I have the same frustration starting at 4.18, still there at 4.19 as per my post here.

For most of what I need mainline is cool - the scheduling is an irritation, but I really need to get sound somehow as well. Watching the noises here and on IRC seems sound is pretty close (may well be OK for others, I am still struggling )

PS - at 4.4 thermal zone1 is also gpu - agree strange but seems not the problem (on its own):

Code:

$ cat /sys/class/thermal/thermal_zone1/type
gpu-thermal
$ cat /sys/class/thermal/thermal_zone0/type
soc-thermal
