I'm runing my JavaFX application on a Udoo Quad, a ARMv7 with Vivante
GPU. I haven't succeeded in using the GPU yet, and I'm endeavouring on
the quest to find out why. It probably has to do something with
drivers, missing libraries etc etc. I'm aware of the page "Porting
JavaFX to additional embedded Linux devices" [1], although I haven't
found the answer there yet that I need.
I tried to look inside the code to see how it works, and why the
native display cannot be gotten. I found the code in
AcceleratedScreen, but I fail to understand where a different
resultcode of 0 is implemented, so who should realize the call? This
will help me to look further.
The output of my javafx program is:
Prism pipeline init order: es2 sw
Using native-based Pisces rasterizer
Using dirty region optimizations
Using system sized mask for primitives
Not forcing power of 2 sizes for textures
Using hardware CLAMP_TO_ZERO mode
Opting in for HiDPI pixel scaling
