Do you know if Valve's changes are at the kernel level; or just the wrappers around the various core components (kernel, x, ...) with perhaps custom driver for their joystick ?
-
I.e, are they just packaging or actually make core changes ?
No, we don't know. We don't work for Valve. I would assume that any Steam OS changes that happen are more about optimization and not changing the way inputs and outputs of information to various components work. If a game designed for Linux had to be altered to work with SteamOS, that would be counterproductive to the entire idea.
