  • Basically just start with what you’re aiming to enable and work backwards (as you’ve started to do). With judicious use of grep find out where that symbol is defined. If it’s in arch configs for other arches but not your own, it’s probably that.

    There may be better tools out there to do this, but in my experience just sleuthing it out a bit will answer your question. The Kconfig system can be complex, but the files are pretty readable.











  • John Carmack, author of the Doom engine, is a long time Linux user and for a while the policy was to open source the idTech engines once they had moved on.

    However, Doom was hugely popular on its own before this, and was actually more pivotal for making Windows a gaming platform (over DOS).

    The reason it runs everywhere is a combination of it’s huge popularity, it’s (now) open source and it’s generally low system requirements.
