Valve's custom kernel patches for SteamOS' kernel; how many are up-streamed into the mainline kernel already?
Title says all, is it possible to use a mainline kernel on a non-SteamOS install or do you have to use Valve's kernel they ship with SteamOS 3.x? Is it possible to find all the the patches they use and compile a kernel yourself?
For the life of me, I can't figure out the search terms I need to find what I'm looking for. On top of that, I'm beginning to think I heard it on a podcast. But I seem to remember an interview with someone at Valve talking about how they were upstreaming EVERYTHING they were doing. I would assume that meant kernel work as well.
