Binary package “tuna” in ubuntu lunar
Low-level system performance tuning for realtime systems
Tuna is used to change the attributes of application and kernel threads, IRQs,
CPUs, and CPU sockets. It can change scheduling policy, scheduler priority and
processor affinity for processes and process threads. It can also change the
processor affinity for interrupts, isolate CPUs, and spread threads or IRQs
across CPUs.
