I was trying to put my streamer (RPi 2) in some "low power" mode by disabling USB (thus also a network) and maybe lower CPU freq. For that I need to track a state of a GPIO pin in asynchronous manner; for now bash script in polling mode seems to work but this is suboptimal.
I tried to tweak the system a bit, however with pacman update I soon understood that this was wrong option

May I ask for pointers to armv7h packages dedicated to corresponding version of RuneOS? Or some SDK?
I gues I could employ syscall ABI (poll, select or sth) but this is an overkill for me in terms of effort.
Thank you!
