@wolf480pl @gigabecquerel but when do you do that? Unix and GPIOs are pretty orthogonal concepts, and if you really want that POSIXness (and many people who've worked long with unixoid systems will look at you strangely if you proclaim you do and ask you which part of your application demands and hardware reality *really* reflects that need), well Zephyr on a microcontroller gets you there without booting a strange application processor with very loose control of its GPIO peripherals.

@wolf480pl @gigabecquerel … and I say that as someone who's not used non-unixoid OSes for anything non-embedded since ca 1999. The parts that make a RPi's GPIO useful are, as far as I can tell, not that it has a solid fork() syscall when running Linux, nor that you can theoretically run a postgres server with data on its SD card, nor that it's easy to port software written for HP-UX to it.
