I have Linux with a kernel that was compiled with the real-time patch, but the config option CONFIG_PREEMPT_RT_FULL was not enabled (it says in /proc/config that it is not set).



Do you now if there is any way to turn this on, without having to recompile the kernel?



I guess it's not possible but maybe there's some way?

          No, it’s a solely compile-time configuration option, there’s no runtime equivalent. You’ll need to rebuild your kernel.
