CPU shielding is a practice where on a multiprocessor system or on a CPU with multiple cores, real-time tasks can run on one CPU or core while non-real-time tasks run on another.
The operating system must be able to set a CPU affinity for both processes and interrupts.

In Linux in order to shield CPUs from individual interrupts being serviced on them you have to make sure that the following kernel configuration parameter is set:
- CONFIG_IRQBALANCE
