Yeah. - Free time. Sure, you need free time to do anything. But the async-workflow of kernel dev is actually fairly forgiving. - A computer. Yes, if you are patient even a fairly slow computer will do. Not a huge barrier for someone who wants to work on something that is only useful if you have a computer to run it on. - A reliable internet connection. You don't even need reliable. Cloning the first time will take a while (a shallow-clone won't be too bad), but the async email workflow is very forgiving of poor connections. Overall I struggle to see how the kernel development workflow could be made more accessible. The only possible improvement would be making it easier to hack on a small part of the kernel without downloading and compiling the whole thing.
