Just achieved a rock-solid 8µs max jitter on a standard 500€ PC (codename: Katana) using a custom Buildroot env and Kernel 6.12.57-rt14.

​The craziest part? It’s running off a 2015 USB 2.0 stick! 🤯

​16 threads stress-tested (cyclictest)
​cpu_dma_latency set to 0µs
​Average jitter: 1µs
​Zero tuning in BIOS
