CPU/GPU Load average - Linux 4.1

Hi all,

i working with an i.MX6s CPU (single core). The system is running with Linux 4.1 and QtQuick 2.3 Application.

 

System Application idle (no animations, only background processes):

If we check the system performance with TOP / HTOP we can see an CPU Load average of ~  0.4 / 0.4 / 0.35

CPU:  3.6% usr  8.3% sys  0.0% nic 85.1% idle  0.0% io  0.0% irq  2.7% sirq

 

 

Then we start some QML Animations and the cpu load average rises up to ~ 1.4 

CPU: 26.5% usr 14.9% sys  0.0% nic 50.5% idle  0.0% io  0.0% irq  7.9% sirq

 

Now my question: Is this an combination from the GPU and CPU load? The system is running smoothly and I cannot see any lags or blocking operations.

Should I be worried or is it only an Linux interpratation from the overall GPU CPU load?

Usually the single core must be lower then 1.0 ->

dual core lower then 2.0 -> and so on.

 

Is it possible to readout the GPU load only?

Has anyone a good explanation?

 

Thanks.
