I'm not sure if it is the safer way to do this, but I think you can
achieve this by c
Changing the policy of the init process at include/linux/init_task.h
worked! Although a lot of tasks asked to change the scheduler policy to
SCHED_NORMAL (and thus the scheduler class to CFS) through
sched_setscheduler(), so I had to add some code there to force the SCHED_RR
policy.
I made the pri

Yes, I've managed to go this far. My problem is discovering where to
change on the code to change the default scheduler. It is my first time
trying to understand the linux sources, and I couldn't find much updated
info online.

The idea is to patch the kernel. I am trying to discover how I can set the
default scheduler for new processes, so that I can test the behavior of any
schedulers that I may write. Do you have any ideas?

Hello,
I am a new developer trying to learn how to tinker with the kernel. I
searched on the internet but couldn't find much info about this (and
couldn't find any info up to date).
My question is, how does the kernel decide which is the default scheduler
that all processes start with? I can chan
