I followed the instructions on the official to compile the Linux kernel into a real-time system that can preempt low-priority work.

Due to some factors I need to use "CONFIG_RT_GROUP_SCHED". But when I searched for availability, the following results appeared: CONFIG_RT_GROUP_SCHED is not set

Then I looked for related messages and found that it doesn't seem to be available. What should I do next? Should I follow this article to compile the kernel to an older version? I don't think this is a good way.

This is my kernel version:5.15.0-1028-realtime

  • Do you honestly need a picture to represent your kernel version? Please use text that can also be indexed and searched! Also, what precisely do you mean with "when I searched for my availability"? Please, be precise with what you did and what you observed. As a new user here, also take the [tour] and read [ask]. – Ulrich Eckhardt Dec 22 '22 at 07:42
