Real-Time capabilities on Debian: Concept and practical use

" summary

Explains real-time (RT) on Debian by defining real-time requirements, detailing the PREEMPT_RT kernel patch set and how it makes Linux low-latency, and describing Debian’s current RT support. Covers practical system configuration and tools — tuned, CPU isolation, IRQ affinity, scheduler tuning — plus latency measurement with cyclictest, installation/configuration steps, and brief notes on achieving RT inside virtual machines. Targets developers and integrators with guidance on when to use RT kernels, tuning and benchmarking techniques, and example use cases like robotics, audio, and energy systems.
