I am a new bee in Linux kernel programming, trying to work with an old kernel Linux 2.6.32 on x86_64. I want to enable the CONFIG_PREEMPT option in it but can not find information about how can I do it. I can compile a new kernel with my preferred options, but do not know what I need to do in this case. So can anyone please tell me
How can I enable CONFIG_PREEMPT option? Do I need to recompile the kernel again with new menuconfig? In that case which option is responsible for CONFIG_PREEMPT?
I think it's trivial for anyone who worked with this before, so please give me your valuable help!
