summary
RTLA ships kernel tracers (os_noise since 5.14, userland tool since 5.17) plus a C user-space front end that automates expert workflows, runs rtla os-noise and rtla timer-lat to collect histograms and timelines, and saves trace files readable by KernelShark. It measures nested interference (IRQ, softirq, thread, NMI), supports a one microsecond fine-tune (default 5 µs), stops on thresholds (examples: 8.8 µs, 500 µs), runs on real systems (24 CPUs, half isolated) and is packaged for Fedora/other distros.
