The only version of linux I know of that's capable of hard real time performance isn't really linux anymore but instead just runs an rtos microkernel underneath linux to make real time guarantess and simply runs linux as the lowest priority task on that kernel. https://en.wikipedia.org/wiki/RTLinux https://en.wikipedia.org/wiki/RTLinux
