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?
