Doesn’t say, but I am curious. They said their workarounds broke other workarounds which caused a lot of implementation delay, but I’m not sure what the actual compromise was to address all that.
Answer probably lies somewhere in the kernel maintainer’s mailing list, I’d imagine. Just not equipped to search for it right at the moment.
Probably some use cases for “regular” users. Someone mentioned music production, though that’s probably more professional than hobby.
To my understanding, you mostly need real time performance for specialty cases where timing is absolutely critical. So I guess if you were building custom drones or custom control boards for drones, you could use real time Linux for that now since the timing could be guaranteed.
