yes. but the companies contributing code don't want to bother to do it right and simply use from user space the kernel real time primitives.

much easier to just add real time code and bugs in the kernel and clock out at 5. (byw, their code isn't even that real time)




What’s a good method for semi real-time, multi process, and multi hardware port synchronization, in user space? All of the real-time kernel code I’ve worked on wasn’t possible 15 years or so. Are there some new user space hooks?


The kernel aint hard real time anyway. In userspace, guess you can pin the task to one or two core, have it the highest rr priority and get more or less the same soft realtime we have in kernel?


So, basically you need to manually pin the processes, be constrained to specific cores, and cross your fingers...
