Hi Jeshwanth,
I'm not an expert in kernel development, but I think that if you receive an
interrupt every 50_micro_seconds IMHO you should definitely deal with it in
kernel mode and maybe also think about enabling Real Time to be more
certain about kernel latencies and scheduling.
The context switch time between kernel and user space I think it's too long
to delegate the elaboration to userspace.
