O! I did not know about such difference between Linux releases for ROCKPro64.
Have you already gathered experience about performance of this new interface? It is very interresting!
I am using a set of own C-functions to handle GPIO. This is very fast and simple, but I miss one functionality: A possibility of async reaction to interrupt from GPIO. I have no clue, how to achieve this in purely user-space process.
Does this new interface allow for something, like select() which returns when GPIO pin changes state?
BR,
Gienek.
